Hyperbaric Oxygen Therapy & Hearing Loss

An Innovative Approach

What is Hyperbaric Oxygen Therapy?

A hyperbaric chamber is a specially designed, pressurised environment where the air pressure can be elevated to up to three times the normal atmospheric levels. This controlled setting facilitates hyperbaric oxygen therapy (HBOT), a medical treatment employed to address a range of health conditions. Recently, HBOT has demonstrated promise in treating sudden hearing loss by improving oxygen delivery to damaged auditory tissues, thereby promoting recovery and enhancing hearing outcomes.

How HBOT can help with hearing loss

Hyperbaric oxygen therapy (HBOT) operates by elevating the oxygen levels in the bloodstream, which is then transported to damaged auditory cells. This increased oxygen supply supports cellular repair, diminishes inflammation, and fosters tissue regeneration, potentially reversing some effects of sudden sensorineural hearing loss (SSNHL). Research indicates that initiating HBOT early can significantly enhance recovery outcomes for individuals with sudden hearing loss.

The process of hyperbaric oxygen therapy

In hyperbaric oxygen therapy (HBOT), patients are situated inside a sealed chamber where the air pressure is progressively raised to two to three times that of normal atmospheric pressure. While in the chamber, patients inhale pure oxygen. Sessions typically last from 60 to 120 minutes, during which patients can relax in a seated or reclining position as the oxygen saturates their bloodstream, aiding in tissue repair and promoting overall healing.

Duration and frequency of treatments

A typical course of hyperbaric oxygen therapy (HBOT) for hearing loss generally involves a series of sessions, with the exact schedule depending on the severity of the condition. Patients may need daily treatments over several weeks, usually between 10 to 20 sessions, to achieve the best possible outcomes.

Safety precautions and common side effects

Although hyperbaric oxygen therapy (HBOT) is generally considered safe, it is crucial to adhere to stringent safety protocols. Patients are closely monitored throughout each session to ensure their comfort and to minimise any risks. Common side effects may include ear discomfort or pressure, akin to what one might experience during air travel. Rare complications can include sinus issues, temporary vision changes, or lung barotrauma. However, these risks are significantly reduced under professional supervision.

Conditions treated by HBOT

Hyperbaric oxygen therapy (HBOT) is used to treat a wide range of medical conditions, including:

Sudden Sensorineural Hearing Loss (SSNHL): HBOT enhances oxygen delivery to damaged auditory cells, promoting recovery.
Noise-Induced Hearing Loss: HBOT may help repair tissue damage from prolonged exposure to loud noises.
Meniere’s Disease: Improved oxygen flow to the inner ear may alleviate symptoms like vertigo and hearing loss.
Tinnitus (in specific cases): Certain individuals with tinnitus have experienced relief through HBOT.

In addition to these ear-related conditions, HBOT is also utilised for treating various medical issues such as carbon monoxide poisoning, severe burns, necrotising infections, air embolism, brain abscesses, severe anaemia, decompression sickness, crush injuries, radiation injuries, chronic wounds, gas gangrene, refractory osteomyelitis, and compromised skin grafts. HBOT aids in reducing inflammation, fighting infection, and enhancing tissue repair across these conditions.

Criteria for HBOT suitability in patients

HBOT may be considered for sudden sensorineural hearing loss (SSNHL) or other ear-related conditions, especially if treatment is initiated within two weeks of symptom onset. It is essential to consult an otolaryngologist to evaluate whether HBOT is suitable for your specific condition. The specialist will review your overall health, the severity of your hearing loss, and any other relevant factors.

Key considerations for determining HBOT suitability include:

The underlying cause and severity of your hearing loss
The timing of the hearing loss onset
Any pre-existing medical conditions, such as lung disease, ear infections, or claustrophobia, which may impact the safety of HBOT
Presence of additional symptoms, such as tinnitus or vertigo
