Idiopathic sudden sensorineural hearing loss is a rapid loss of hearing arising from the inner ear or hearing nerve without an identified cause. It often affects one ear and may occur with tinnitus or dizziness. Sudden hearing loss needs prompt medical and hearing assessment because the treatment window is limited.
The American Academy of Otolaryngology–Head and Neck Surgery guideline lists HBOT combined with steroid treatment as an option within two weeks of onset, or as salvage treatment within one month. These are options for appropriately assessed patients, not a guarantee that hearing will return. An ear, nose and throat specialist should guide the diagnosis, treatment choice and follow-up hearing tests.
