Title: [abstract] Case report of sudden hearing loss restored with hyperbaric oxygen therapy
Author: Markovitz, GM; Sprau, SE; Chin, WG
Abstract: Introduction/Background: Idiopathic sensorineural hearing loss (ISSHL) is an otologic emergency with no known cause and poor outcome. Studies have described cochlear hypoxia in the pathophysiology. Conventional medical treatment attempts to restore cochlear oxygen tension by improving blood circulation. Hyperbaric oxygen therapy (HBO2T) should help by improving oxygenation and has been reported to show benefit. HBO2T is commonly used in Europe but infrequently in the United States because it is not an approved therapy by third-party payers, as there are no controlled blinded studies that demonstrate benefit. Materials and methods: 39-year-old woman presented with sudden onset left-sided hearing loss two weeks after an upper respiratory tract infection with no tinnitus or dysequilibrium. Initial evaluation six days after symptoms began showed both tympanic membranes were normal. Weber lateralized to the right, positive bilateral Rinne, extraocular movements were intact, with fatiguing nystagmus on left lateral gaze, and sway to left with Romberg. Initial audiogram showed 84% speech recognition on right and 20% on left. She was diagnosed with ISSHL and started on prednisone 50 mg per day. She was referred for HBO2T seven days later due to lack of clinical improvement. She received six HBO2Ts over three days at 2.21 ATA for 90 minutes of oxygen breathing time, then daily for a total of 20 sessions. Prednisone was gradually tapered. Results: After the first HBO2T she noticed that her hearing was improved. Repeat audiometry after the seventh HBO2T showed 88% speech recognition on right and 64% on left. Weekly audiometry showed continued improvement: 84% right and 72% left; final test 88% right and 92% left. Summary/Conclusions: We describe a case report of ISSHL that did not respond to conventional medical therapy. The patient’s hearing was restored with HBO2T We suggest that HBO2T should be considered early for patients with ISSHL.
