- Published on: 11 April 2019Hyperbaric oxygen treatment can be an early adjunctive therapy in sudden deafness
We read with interest the article by Bayoumy et al. concerning the effects of hyperbaric oxygen therapy (HBOT) associated with corticosteroid therapy in military personnel with acute acoustic trauma1. This paper helps to discuss about the most appropriate treatment of sudden deafness (SD). As recently stated, a spontaneous recovery, in the general population, is less than 40%. The precise role of HBOT has not yet been clearly established2. Our clinical experience during the last 15 years in a second referral hyperbaric center indicates the need of clear guide-lines, for the treatment of this acute disease. Nowadays there are two main therapeutic approaches to SD of different origin, the corticosteroid medication and HBOT.

Clearly, at first, it has to be ascertained the nature of a deafness excluding, cerebral diseases, vascular, traumatic and neoplastic. A subsequent otolaryngology evaluation enables to ascertain possible associated vestibular diseases, and to measure Pure Tone Average. Medical contraindications to HBOT and corticosteroids medication have to be excluded. An early treatment, not beyond the first 48 hours after the acute event is recommended 1. Today the HBOT standardized protocol, consists in a daily oxygen 100% at 2.2-2.5 atmosphere for 90 minutes, for a minimum of 10 sessions in case of satisfying functional recovery. On the contrary, in case of absolutely negative results, the treatment should be interrupted. Otherwise, HBOT can be prolonged to a...Conflict of Interest:
