Introduction
Sudden sensorineural hearing loss is usually associated with microcirculatory disturbances in the inner ear, which may lead to hypoxia and inadequate nutrition of inner ear cells. Under hyperbaric oxygen conditions, blood oxygen partial pressure and oxygen content increase, potentially improving blood flow in small vessels and thereby enhancing the metabolic state of inner ear cells, which may help restore hearing.

Under normal circumstances, the reasons why hyperbaric oxygen therapy may treat sudden sensorineural hearing loss include enhancing local blood supply, suppressing inflammatory responses, improving microcirculation in the inner ear, reducing inner ear edema, and promoting nerve repair. It is recommended to seek timely medical attention and follow a treatment plan under a doctor's guidance, including general management and medication. Specific explanations are as follows:

1. Enhancing Local Blood Supply

Hyperbaric oxygen therapy generally increases the amount of dissolved oxygen in the blood, thereby enhancing oxygenation capacity in cochlear microcirculation. In a hyperbaric oxygen environment, the solubility of oxygen increases, which may help improve ischemic conditions in the cochlea caused by various factors and promote the repair and regeneration of damaged tissues.

2. Suppressing Inflammatory Responses

Hyperbaric oxygen therapy has anti-inflammatory effects locally, potentially reducing the release of inflammatory mediators, thus alleviating edema and inflammation in inner ear tissues and facilitating the restoration of normal inner ear function.

3. Improving Inner Ear Microcirculation

Sudden sensorineural hearing loss is often associated with impaired microcirculation in the inner ear, which may lead to hypoxia and inadequate nutrition in inner ear cells. Under hyperbaric oxygen conditions, elevated partial pressure and content of blood oxygen may enhance blood flow through small vessels, thereby improving the metabolic state of inner ear cells and potentially aiding in hearing recovery.

4. Reducing Inner Ear Edema

Patients with sudden sensorineural hearing loss often experience inner ear edema, which can cause hearing decline. Hyperbaric oxygen therapy improves capillary permeability and reduces exudate production, thus relieving inner ear edema. Symptoms such as ear fullness and ear pain may also occur. Under medical guidance, medications such as amoxicillin capsules, cefaclor sustained-release tablets, or levofloxacin tablets may be used for treatment.

5. Promoting Nerve Repair

Sudden sensorineural hearing loss may be related to damage to inner ear nerves. Hyperbaric oxygen therapy promotes nerve repair and restores neural conduction function, which helps improve hearing. Patients may also experience symptoms such as nausea, vomiting, and tinnitus. Under a doctor’s advice, medications such as vitamin B complex tablets, mecobalamin tablets, or oryzanol tablets may be prescribed for treatment.

In daily life, patients are advised to maintain a positive mindset, avoid emotional excitement, balance work and rest appropriately, and ensure sufficient sleep, all of which contribute to recovery.
