Kayacık SN, Gümüş Selek FZ, Aslan A, Karabakan R, Kıratlı Ü. Hyperbaric Oxygen Therapy in Stroke- Related Sudden Hearing Loss: A Case Report. Undersea Hyperb Med. 2026 First Quarter; 53(1):99- 104. Introduction: Sudden sensorineural hearing loss (SSNHL) refers to a rapid decline in hearing of 30 dB or more that develops within three days, impacting at least three consecutive frequencies in one or both ears. Case Report: This case report examines the improvement in hearing levels through hyperbaric oxygen treatment in a 74-year-old male patient who developed sudden hearing loss following a stroke. Discussion: After 15 days of neurological treatment, an audiological assessment revealed a 70 dB hearing loss in air conduction in the left ear. The patient initially received intravenous methylprednisolone for ten days, followed by five intratympanic steroid injections. Despite these treatments, no significant improvement in hearing was noted. The patient subsequently received 14 sessions of hyperbaric oxygen treatment, significantly improving hearing function. Keywords: Hyperbaric oxygen; sudden sensorineural hearing loss; stroke.
