Ozone Therapy for Ear, Nose and Throat Conditions: What the Evidence Shows

At a glance:

1. Ear, nose, and throat conditions can be bothersome, recurring, and hard to treat. For many conditions, only symptom management is available.
2. Ozone therapy gives the body a different kind of help: it fights microbes, calms inflammation and supports healing. The best evidence so far is for sudden hearing loss and chronic ear discharge.
3. Ear and breathing ozone oil, along with topical ozone oil and water use are easy ways to use ozone therapy for ear, nose, and throat conditions at home. However, systemic methods, such as rectal insufflation and ozone IV can also be very beneficial. 
4. Beyond just disinfecting on contact, ozone therapy jumpstarts and speeds healing, improves blood flow and oxygenation, and supports mitochondrial function. 
5. Ozone therapy may help with hearing, balance, sinus issues, problems with the head, or even allergies, cold, and flu. 
6. For tinnitus, results vary from person to person: some people report quieter ringing and many notice no change. The tinnitus section below covers what the studies show and when to see an ENT first.

Ear, nose, and throat (ENT) conditions can be very bothersome and hard to treat. Many people struggle with recurring issues that warrant surgery or ongoing medications to control the symptoms. Moreover, some ENT conditions like hearing loss and tinnitus tend to arise with age. Whereas, some infectious ENT conditions may often come back after successful treatment. When infections in the ENT areas remain untreated, they run the risk of progressing to the brain. 

For a complete overview of conditions, see what diseases does ozone therapy treat.

Ozone has both antimicrobial and regenerative benefits. Studies have tested it against recurring and treatment-resistant infections, including chronic ear discharge. The gas can penetrate narrow areas and hard-to-reach spaces like the sinus cavities and ear canal. Therefore, ozone therapy may have many unique advantages over conventional treatments.

Important Considerations

Ozone ear insufflation is generally well tolerated in studies when it is dosed correctly. Too high a concentration can cause temporary, minor irritation.

Because ozone can be toxic to the lungs, it is important to proceed with caution. Ideally, work with a provider trained in ozone therapy to determine the appropriateness of the treatment, the correct dosage, and duration, and to minimize the risk of adverse effects. 

Ozone therapy may also be an add-on to your current treatments rather than as stand-alone treatments.

Various ways to use ozone therapy for ears, nose, and throat conditions

Ear insufflation

Ear insufflation means putting gas into the ear canal. For ozone ear therapy, you’ll use a headphone or stethoscope-like device to push ozone into the ear canals.

The eardrum separates the ear canal from the middle ear. The middle ear connects to the back of your nose through the eustachian tube, which explains why blowing your nose can affect your ears. Ozone put into the canal acts mostly on the canal and nearby tissue, plus whatever the body absorbs. 

Ear insufflation may help with conditions involving the ears (hearing and balance issues) as much as areas near the ear canals, including:

• Jaws and jawbones
• The sides of the head
• Sinus cavities
• The brain and nerves in the head
• Lymph nodes and glands near the ears or jaws

Ozone oil or water drops

Ozone oil or ozone water can be dropped into the ears, most likely to treat infections or stimulate regeneration. 

Ozone oil (ozonated oil) and ozone water drops introduce the therapeutic properties of ozone directly into the ear canal, providing a local treatment for various ear conditions.

Breathing ozone oil  

Breathing ozone oil involves the infusion of ozone through olive oil, then the vapor is passed directly into the nasal passages and sinuses. This avoids the toxic effects of ozone inhalation. 

Practitioners use BOO for sinus problems, such as infections or loss of smell. Since the sinus cavities are connected to the brain, it may also help deliver the benefits of ozone to the brain.  

Rectal insufflation

Rectal insufflation involves placing ozone into the gut through the rectum. Ozone may interact with the blood through large veins in the rectum area, replicating some whole-body benefits of ozone autohemotherapy. Some small studies of whole-body ozone report less tinnitus, though the results are mixed (see the tinnitus section below).

Nasal ozone insufflation: how ozone reaches the nose and sinuses

Nasal ozone insufflation means getting ozone into the nose and sinuses. Some clinics run ozone gas into the nostrils at a low concentration while the patient holds their breath. We don't recommend doing that at home: ozone gas that is breathed in irritates the lungs, and a single breath is enough. These are the safer ways people get ozone to the nose and sinuses:

• Breathing ozonated oil (BOO). The ozone gas is bubbled through olive oil first, and you breathe the vapor through a nasal cannula. Practitioners use it mainly for sinus, throat and lung infections. See the BOO protocol.
• Ozonated glycerin nasal spray. Ozonated glycerin mixed into saline at about 10% (start at 5% if your nose is sensitive), sprayed 2–3 times a day. No generator is needed. See the ozonated glycerin protocol.
• Ozone water sinus rinse. Freshly made ozone water used as a sinus wash.
• Ear insufflation. The ear connects to the back of the nose through the eustachian tube, so some people use ear insufflation for sinus pressure as well. See the ear insufflation protocol.

Research on ozone for sinusitis is small and mostly older. A 1996 study looked at ozone preparations added to standard treatment for sinusitis [22]. Keep expectations modest, and see a doctor for a sinus infection that lasts more than 10 days or comes with a high fever, swelling around the eyes or a severe headache.

Ozone therapy devices and supplies for ear, nose, and throat conditions at home

If you have a home ozone therapy machine, you can produce the ozone, or ozonate water to use for ENT treatments along with insufflation kits. For oil, buy lab-tested ozone oil that lists its peroxide value; we do not recommend making it at home. You can also purchase ozone water to use as a rinse. The following are devices or supplies that can help with ENT conditions, based on clinical studies.

• Medical-grade ozone generator or ozone therapy machine
  • Produces medical-grade pure ozone-oxygen gas for various therapeutic applications.
  • Can produce ozone-oxygen gas at the desired concentration for nasal or ear insufflation, or to produce ozone oil or water.
• Ear Insufflation Kits
  • Consist of an ozone generator, tubing, and a special earpiece for delivering ozone directly into the ear canal.
  • Are specifically designed for pushing ozones into the ear canals
• Breathing Ozone Oil Devices
  • Passes ozone through oil, and then passing the resulting vapor into the nasal cannula
  • May help with treating sinus infections, allergies, and other nasal or respiratory conditions.
• Rectal Insufflation Devices
  • Introduce ozone gas into the rectum to deliver gut and whole-body benefits.
  • May help with treating conditions that benefit from systemic ozone effects, such as inflammatory conditions and infections
• Ozonated Water: may be swallowed, gargled, or used as ear or sinus wash
• Ozone Oil [3] can be diluted into the right concentration and dropped into the ear

How ozone therapy helps with ear, nose, and throat conditions

1. Antimicrobial to sterilize and clean your ears

Ozone exposures can kill bacteria, virus, and fungi in the ear and sinus cavities, and used locally it does not disturb the gut flora the way oral antibiotics can. The gas also breaks up biofilm, where these microbes can hide from antibiotics. In a controlled study of chronic ear discharge, adding ozone-oxygen irrigation of the middle ear (given by an ENT through the perforation) stopped the discharge in most patients [4].

2. Anti-inflammatory and immune modulation

Ozone therapy delivers tiny amounts of oxidants that jumpstarts and rebalances the immune system. This may help resolve stagnant inflammation that inhibits healing. Also, since imbalanced immune functions can cause allergies or autoimmunity, ozone treatment may benefit allergies and autoimmune-related hearing loss.

3. Improves oxygenation and blood flow

Blood flow brings oxygen and nutrients, which are crucial for healing. When you have acute injuries or infections, the body tends to naturally reduce blood flow to the area, which can slow down the healing. Ozone therapy can give oxygen to the tissue and promote blood flow. This improves healing processes in injuries like inner ear loud noise trauma and eardrum perforations [29], [31].

4. Stimulates cellular antioxidant defenses

Excess oxidative stress, which can come from infections and inflammation, can interfere with healing. Ozone therapy introduces a tiny amount of oxidative stress that stimulates the body’s antioxidant responses, helping to mitigate oxidative stress and improve cellular health. This is useful for managing chronic conditions and enhancing recovery from acoustic trauma [29].

5. Stimulates mitochondrial function and anti-aging pathways

Some ENT conditions such as tinnitus and hearing loss tend to arise due to age. Hearing loss has also been linked to a higher risk of dementia, so ear health and brain health may be connected. By stimulating mitochondrial functions and cellular anti-aging pathways, ozone therapy may help with both ear and brain health. 

Ear, Nose, and Throat Conditions that May be Helped with Ozone Therapy

Ozone therapy was used to treat many ENT conditions with studies describing protocols and their effectiveness back in the 1800s [9, 10].

Since then, ozone therapy devices and technology have significantly evolved to produce purer ozone for safer therapeutic uses. Modern clinical studies have since tested many of the uses those early physicians described.

Here is the strongest evidence for each condition on this page, so you can see where ozone stands before reading the details:

Vertigo

Vertigo is a chronic condition when a patient feels spinning or swaying even though they’re stationary. It is an inner ear disorder that affects the brain’s ability to balance the body [14].

Some people who have vertigo also have tinnitus. 

Symptoms may include:

• Dizziness or a spinning sensation
• Nausea and vomiting
• Balance problems
• Nystagmus (abnormal eye movements)
• Headache and sweating

Ozone therapy addresses underlying factors like inflammation and circulation that can contribute to the condition.

A systematic review examined 264 studies and found three to be of sufficient quality for analysis [42].

The most remarkable one out of three was a Cuban uncontrolled trial with 50 patients.

These patients had suffered from various symptoms of vestibulocochlear syndrome lasting for over three months, including hearing loss, tinnitus, mild peripheral vertigo, and nystagmus. They received 20 ozone injections into the area between the cervical spine 2 and 3 [15]. 

The study found that:

• 90% had improved vertigo
• 80% had improved hearing loss
• 65% had improved tinnitus
• 100% had improved nystagmus

Another study in this review examined patients with Meniere’s disease. Participants received 8 mg/L of ozone at 60 mL/min for 10 minutes and also received the standard treatment called pressure-pulse therapy for 10 minutes each day. The treatment period lasted 10 days. Patients reported fewer and milder attacks and less tinnitus, but the hearing tests did not change [16]. 

No side effects were reported in the 50-patient study. There was no comparison group, so the results are promising but not proof, and they point to ozone as worth testing in proper trials for vestibular and cochlear problems [15].

Hearing loss

Hearing loss is the partial or total inability to hear sounds in one or both ears. It's classified into two main types: sensorineural and conductive [17]:

• Sensorineural: Caused by damage to the inner ear or the nerve pathways from the inner ear to the brain.
• Conductive: Results from obstructions or damages to the outer or middle ear that prevents sound from being conducted to the inner ear.

Conventional treatments for hearing loss include hearing aids, cochlear implants, surgery, antibiotics to treat infections, and treating other underlying conditions. 

The hearing-loss evidence comes from clinic studies of sudden sensorineural hearing loss, where ozone (IV autohemotherapy) was used alongside standard care. We found no study of ozone for conductive hearing loss.

In a prospective, randomized, double-blinded, placebo-controlled, parallel group clinical trial, forty five patients suffering from sudden sensorineural hearing loss (SSNHL) either received IV autohemotherapy or placebo treatment. 

23 out of 30 (77%) patients in the ozone group significantly improved their hearing. Whereas, only 6 out of 15 (40%) in the control group improved their hearing. Furthermore, patients treated with ozone therapy significantly improved all measured hearing parameters - mean hearing gains, pure tone averages, speech reception thresholds, and subjective recovery rates. 

In conclusion, ozone therapy might potentially be very helpful for sensorineural hearing loss, but benefits are individual [18].

Tinnitus: what we know and what we don't

Tinnitus is hearing a sound, such as ringing, buzzing, hissing or clicking, when there is no outside sound. It affects about 15–20% of people [11]. Tinnitus is a symptom with many possible causes: hearing loss, loud-noise damage, ear infections, earwax, jaw (TMJ) and neck problems, blood flow problems and some medicines. The cause matters, because it decides whether ozone has anything to work on.

Why ozone is discussed for tinnitus

The inner ear needs a steady supply of oxygen and is sensitive to oxidative stress and poor blood flow. Ozone therapy is thought to help by:

• Improving blood flow and oxygen delivery to the ear tissues
• Switching on the body's own antioxidant defenses
• Calming inflammation and helping clear infection, where that is part of the problem

In an animal study, guinea pigs given ozone before the blood supply to the inner ear was cut off had less damage to the cochlea than untreated animals [39]. Animal results like this don't always carry over to people.

What the research in people shows

• The best-controlled tinnitus trial found no clear benefit. In a randomized study of 68 people, 10 sessions of ozone autohemotherapy did not reduce tinnitus loudness compared with no treatment. Quality-of-life scores improved in the ozone group, but by no more than in the other groups [13].
• Uncontrolled studies report better results. In a study of 50 people with inner ear (vestibulocochlear) symptoms, 20 sessions of ozone injected in the neck at C2–C3 were followed by tinnitus improvement in 65% of patients, with no side effects. There was no comparison group [15].
• Tinnitus linked to the neck. A 2026 study of 256 people whose dizziness and tinnitus were linked to a herniated neck disc used CT-guided injections of an ozone-oxygen mix with saline and a steroid. A year later, 75.6% of those with tinnitus reported relief. The injection also contained a steroid and there was no control group, so how much of the effect came from ozone isn't known [40].
• Sudden hearing loss, which often comes with tinnitus. In a double-blind trial of 45 people, ozone autohemotherapy led to hearing recovery in 77%, compared with 40% on placebo [18]. In a 106-person study, adding ozone to steroids raised the response rate from 51% to 82% [41]. This is the strongest ozone evidence for the ear, though these studies measured hearing recovery rather than tinnitus.
• Reviews. A 2022 systematic review found only a handful of usable studies and concluded that well-run randomized trials are still needed [42]. A shorter 2022 review reported that ozone resolved nighttime tinnitus in the studies it looked at [12], but it was based on very few patients, so read that result with caution.

The honest summary: some people report quieter ringing after ozone, many notice no change, and nobody can predict who will respond. Results look more promising when tinnitus comes with sudden hearing loss, inner ear circulation problems, a neck problem or an ear infection. Long-standing tinnitus from noise damage or age-related hearing loss has not been shown to respond. No study shows that ozone cures tinnitus.

Which ozone methods people use for tinnitus

• Ear insufflation is the most common home method for ear symptoms. Our ear insufflation protocol covers the dosing schedule week by week.
• Whole-body methods: IV ozone (major autohemotherapy) in a clinic, which is what the sudden hearing loss trials used, or rectal insufflation at home.
• Injections around the neck, given by trained doctors, as in the inner ear and neck disc studies above [15, 40].

See an ENT or audiologist first

Get your ears checked before trying ozone. Go urgently if the tinnitus is in one ear only, pulses with your heartbeat, or came with sudden hearing loss, dizziness or facial weakness. Sudden hearing loss is treated as an emergency, because steroids work best when started within the first two weeks. In the studies above, ozone was given alongside standard care.

Temporomandibular Joint disorder (TMJ)

Temporomandibular joint disorder, (also abbreviated TMJ, TMJD, or TMD), is a chronic pain disorder affecting the jaw joint and surrounding muscles and ligaments. TMJ may arise from physical stress on the joints or muscles, misalignments, or other musculoskeletal disorders. Symptoms may include pain, limited jaw movements, disrupted sleep, headache, and teeth grinding that can wear down dentin [19]. 

TMJ is a condition with no official cure, as most treatments like massages, painkillers, and antidepressants only manage the symptoms. Since the TMJ joints are very close to the ears, it's often treated by ozone ear insufflation. 

Ozone therapy for TMJ involves:

• Ozone ear insufflation
• Application of ozonated oils on the skin near the joints
• Injection of ozone gas into the jaw joints (in a medical or dental office)

Pain disorders tend to improve with more blood flow, tissue oxygenation, and lower inflammation. Ozone therapy may help with TMJ by providing these factors and also support joint regeneration in cases of significant joint wear. 

Most clinical trials of ozone therapy for TMJ injected the gas into the joint. However, many ozone dentists use ear insufflation as a less invasive way to treat TMJ with ozone.

A review of six articles involving 176 patients investigated the impact of ozone therapy on TMJ disorders, particularly in terms of pain management. Most trials reported that ozone therapy significantly helped with pain and improved jaw movements in TMJ patients [20]. In one trial, 87% (26/30) of patients in the ozone therapy group completely resolved their TMJ.

Sinus infection

Sinus infections, or sinusitis, occur when the cavities around nasal passages (sinuses) become inflamed and swollen. When it lasts 12 weeks or more despite treatment, it is called chronic sinusitis. This condition can interfere with drainage and cause mucus buildup [21].

The causes could be viral, bacterial, fungal, or allergies. You may feel congestion or blockage with constantly swollen sinus or discolored mucus. Some patients may also feel facial pain or pressure.

Ozone therapy for sinus infections can be applied through nasal or ear insufflation, or a sinus rinse with ozone water. The ozone treatment can help with:

• Eliminating pathogens
• Jumpstarting immune function to clear inflammation and heal
• Breaking mucus
• Reducing congestion 

In a small 1996 study of 39 patients with sinusitis, those given ozone preparations alongside standard treatment stopped discharging mucus 2 - 3 days earlier than the control group [22]. 

That makes ozone a reasonable add-on to standard sinus care, though larger modern studies are still needed.

Brain fog

Brain fog (also called cognitive dysfunction or mild cognitive impairment) is not a medical condition. It’s a vague term typically used to describe symptoms like declining mental clarity, focus, memory, and other aspects of cognitive function [23]. Brain fog could be a mild symptom from lifestyle factors such as sleep deprivation, poor nutrition, and stress. However, it could also be a symptom of more serious mental health and neurologic conditions, such as depression and Alzheimer’s disease. In some cases, brain fog may be an early symptom of developing serious conditions or a symptom during recovery from an illness.

Ozone therapy works by boosting tissue oxygenation, blood flow, and mitochondria function, making it a promising treatment for brain and mental health [24].

The leading root causes of brain fog include increased oxidative stress and inflammation, along with poor mitochondria function. Some medications and hormone imbalances can also contribute to brain fog. Low oxygenation and brain blood flow can also contribute to brain fog. These causes have many ripple effects, such as lower acetylcholine, a key neurotransmitter in cognition and memory.

You can’t directly apply ozone to the brain. However, rectal insufflation or ozone IV can deliver full-body effects, including the brain. Also, ear and nasal insufflation with ozone oil vapor may deliver some brain benefits of ozone, just as the sinus membrane can allow some substances into the brain. In fact, many people anecdotally report improved mental clarity after receiving ozone IV, saunas, and rectal insufflation. 

A clinical trial of 16 patients experiencing treatment resistant depression and anxiety due to cancer treatment and advanced non-oncologic diseases received ozone therapy. 56% of the study participants were already receiving anxiolytic and/or antidepressant treatments. Ozone therapy resulted in significant improvements in anxiety and depression, as evidenced by both the Hospital Anxiety and Depression Scale (HADS) subscales and the EQ-5D-5L questionnaire.

This study underscores the potential of ozone therapy as a complementary treatment modality. It may help with mental wellbeing and cognitive function, even though the studies in healthy people are limited [25].

Ear infections and ear discharge

Ear infections refer to bacteria or viral infections in the middle ear. It can also happen as a complication from cold, flu, or allergies. 

Ear discharge, or otorrhea, refers to any fluid from the ear. It's a symptom rather than a disease itself and can vary in appearance (clear, bloody, or pus-like) depending on the cause [26]. You may have fluids leaking from the ears along with ear pain, and potentially hearing loss.

Common causes of ear discharge include ear infections, perforated ear drums, and ear surgery. 

The standard treatments for ear infections include antibiotics, anti-inflammatory or pain medications, along with mechanically removing wax or pus from the ears. While these treatments are essential, they allow the damaged ear tissues to regenerate without boosting the regenerative capacity. Also, ear infections can often recur, especially in children, leading to frequent antibiotic use [27]. 

Ozone therapy can uniquely help with ear infections and ear discharge by:

• Helping to disinfect the ear canal with its broad-spectrum antimicrobial properties
• Stimulating the immune cells in the infected tissues to work against the microbes and heal the damages
• Overall supporting tissue regeneration by boosting oxygenation and blood flow
• Reducing pain and discomfort
• Helping to avoid damage to the gut flora from oral antibiotic use

Ozone therapy for ear discharge can be used alone or in combination with conventional treatment. It could be ear insufflation, ear wash with ozone water, or drops with ozone oil. 

A clinical trial enrolled 52 patients diagnosed with chronic purulent mesotympanitis (CPM), or persistent ear discharge and inflammation of the eardrum. Participants received irrigations of the middle ear (the tympanic cavity, through the perforation by an ENT) with an oxygen-ozone mix at 600 microg/l, 5-7 times. This is a clinic procedure, not the home ear insufflation described above. For comparison, 18 control patients received standard treatment without ozone-oxygen irrigations.

81% of patients in the ozone group stopped having ear discharge and inflammation of the eardrums. The ozone group also had reduced inflammation markers, and the bacteria in their ears became more sensitive to antibiotics. 

This article concluded that ozone therapy could help with inflamed eardrums by directly eliminating pathogens, enhancing antibiotic efficacy, reducing inflammation, and improving the immune response and oxygenation of the affected tissues [4]. It can be a powerful part of a multi-faceted approach.

Inner ear acoustic trauma

Inner ear acoustic trauma is when very loud noise damages your inner ear structures, like the cochlear or ear drums. This can cause temporary or permanent hearing loss, ear fullness sensation, and tinnitus [28].

Common causes may include:

• Exposure to loud noises (above 85 decibels), such as machinery, explosions, or loud music
• Sudden, extremely loud blasts of sound, like gunfire or fireworks close to the ear

Home-based ozone therapy for inner ear acoustic trauma might involve ear insufflation or the use of ozonated oils. These methods aim to sterilize, promote healing of the damaged inner ear structures, and mitigate symptoms like tinnitus and hearing loss.

A rat study tested the protective effects of ozone therapy on hearing loss from noise trauma. Thirty-two rats were distributed into four treatments- acoustic trauma, ozone given 24 hours before acoustic trauma, ozone without undergoing trauma, and no treatment or exposure.

Acoustic trauma was induced using 105 dB white band noise for four hours. To evaluate the impact of the interventions, the animals received two tests: Distortion Product Otoacoustic Emissions (DPOAE) and Auditory Brainstem Response (ABR) tests on days 1, 5, and 10 following the trauma. The rats given noise alone stayed damaged on days 1, 5 and 10. The rats given ozone first had significant improvements on both tests on days 5 and 10, recovering close to baseline measurements.

Based on this study, ozone seems to speed recovery from noise damage in rats. It has not been tested this way in people yet [29].

Other types of eardrum injuries

Eardrum injuries (tympanic membrane perforation) can disrupt normal hearing and make the middle ear more susceptible to infections [30].

Common causes may include:

• Middle ear infections (otitis media) leading to increased pressure and rupture
• Trauma, such as a severe blow to the ear, sudden pressure changes, or inserting objects into the ear
• Loud sounds or blasts (acoustic trauma)

Symptoms may include:

• Ear pain, potentially sudden and sharp
• Hearing loss or diminished hearing in the affected ear
• Tinnitus (ringing in the ear)

Ozone therapy can help keep the ear canals sterilized to avoid infections and complications. It can also promote healing and prevent further complications. You can do it from home with ear insufflation, ozone oil ear drops, or ozone water irrigations. However, if you have perforated eardrum, ear insufflation is usually contraindicated but you can use ozone therapy in other ways.

An animal study explored the histopathological effects of both local and systemic ozone therapy on experimental eardrum injuries. After inducing traumatic perforations, rats were segregated into four groups: no intervention, 0.5 mL of ozone oil ear drop, 1.0 mL of 1 µg/mL ozone as rectal insufflation, or ozone oil ear drop + rectal insufflation for 10 days. 

Groups treated with ozone—locally, rectally, or a combination of both—showed significantly enhanced cell growth and tissue regeneration when compared to the control group. This means the ozone treatment led to a marked improvement in wound healing (p<0.05). Local and rectal ozone helped the eardrums heal in rats, which suggests it is worth studying in people [31].

Allergies

Allergies are the immune system's hypersensitive reactions to otherwise harmless environmental substances (allergens) [32].

In addition to the presence of allergens, genetic factors, gut flora, and your immune tendency play a role.

Ozone may help particularly by helping to balance inflammation in the sinus. However, it’s not safe to inhale as ozone inhalation can damage the lungs or exacerbate asthma. 

Ozone therapy at home for allergies might involve nasal or ear insufflations which promote a balanced immune response in the sinus and ear cavities. However, whole-body therapy such as IV ozone and rectal insufflation may also be beneficial.

A clinical trial explored the effects of systemic ozone therapy on various biomarkers and lung function in asthma patients, focusing on serum immunoglobulin E (IgE) levels, human leukocyte antigen DR (HLA-DR), and antioxidant pathways. Asthma patients underwent two distinct ozone therapy protocols for a year, including major autohemotherapy (MAHT) with doses of 4 and 8 mg across 15 sessions for each cycle (5 - 6 months each), and rectal insufflation (RI) at a dose of 10 mg for 20 sessions per cycle.

IgE and HLA-DR levels fell with all three treatment types, while glutathione and the glutathione enzymes (peroxidase, reductase and S-transferase) rose. Lung function and symptomatology improved. MAHT at 8 mg showed the greatest benefit, followed by MAHT at 4 mg, and finally rectal insufflation at 10 mg. These findings illuminate the potential role of systemic ozone therapy to help manage allergic conditions like asthma [33].

Meniere's disease

Meniere's disease is a chronic disorder of the inner ear characterized by episodes of vertigo, hearing loss, tinnitus (a ringing or buzzing noise in the ear), and a feeling of fullness in the affected ear. The condition typically affects only one ear.

The exact cause is unknown, but it could be related to a fluid imbalance in the inner ear. Potential contributing factors include viral infections, autoimmunity, genetics, and abnormal fluid drainage [34].

Ozone therapy for Meniere's disease can involve ear insufflation or systemic applications such as ozonated water drinking or rectal insufflation to reduce symptoms and improve inner ear health.

A clinical trial involved 15 patients (8 men and 7 women) who had been experiencing Meniere's disease for 1 - 3 years, all of whom had permanent sensorineural hearing loss. Efficacy of the treatments was evaluated using objective hearing measures, such as otoacoustic emissions and the short-increment sensitivity index (SISI) tests. The patient also submitted subjective reports before and after the therapy. Treatment protocol consisted of simultaneous ozone therapy and pressure-pulse treatments, administered in 10-minute sessions daily over a span of 10 consecutive days. 

Results revealed that while the objective measures did not statistically significantly change post-treatment, the ozone group had much better subjective wellbeing. Specifically, patients reported less frequent and severe Meniere's disease attacks, as well as a reduction in tinnitus. 

The hearing tests didn’t change, but fewer and milder attacks matter a lot to people living with Meniere’s, which makes ozone therapy worth discussing with your doctor [16].

Cold and flu recovery

Cold and flu are very common viral infections that affect the ears, nose, and throat. There is no cure aside from some antivirals and supportive therapy. 

As an immunomodulator, ozone can help support the immune system to reduce the duration and severity of the illness. Ozone may also deactivate viruses and improve tissue oxygenation, which may help with symptoms from lower respiratory capacity due to the illness [35].

Most clinical trials in this category arose during the pandemic as it was used as an experimental treatment for severe cases. They were delivered as major autohemotherapy, rectal insufflation, and as ozone oil nasal sprays [36]. 

In a report of 4 severe case patients, rectal ozone insufflation (35 mcg/mL, 1mL/s, 100mL of ozone-oxygen gas for 5 - 7 sessions) was a last resort treatment. The patients still needed high-flow oxygen despite all the standard treatments. Aside from brief bloating, there were no side effects from rectal insufflation. After five sessions, they experienced significant clinical, biochemical, and radiologic improvements [37]. 

Another report described 2 cases that were hypoxic despite oxygen treatment. One was a 60-year-old woman who was on high-flow mechanical ventilation. Another was a 40-year-old man who was hypoxic with an oxygen face mask. After ozone rectal insufflation (25.2 mg of ozone), the woman on the ventilator improved and went home on day 10. The man, who was isolating at home, came off oxygen within 3 days of one session [38].

In conclusion, less invasive ozone therapy, such as rectal and nasal insufflation, may help keep immune function healthy. The studies so far are small case reports in severe COVID-19, so there is no direct evidence yet for everyday colds.

Conclusion:

Ozone therapy for ENT conditions is generally well tolerated in studies when dosed correctly, and it offers some benefits that conventional care does not, especially for stubborn infections and sudden hearing loss. For instructions, check out our articles on:

Finding a practitioner for ear, nose and throat ozone therapy

Start with an ENT or your own doctor so you know what you are treating. Then choose a doctor or clinic with formal ozone training; the Find an Ozone Doc directory lists clinics near you, and ozone therapy prices by treatment shows what to expect. Ask which method they use (ear insufflation, IV ozone, injections or a home program), how many sessions they plan, and how they will measure whether it is working, such as a hearing test, a symptom questionnaire or a follow-up exam before and after. If you are searching for ozone therapy for tinnitus near you, the same questions apply: a good practitioner will look for the cause of the ringing first.

Practitioners who want to add ozone to their practice can start with our free IV Ozone 101 training. If you want to use ozone at home, our free guide explains how to get started safely.
