[Hyperbaric oxygen [HBO] on sudden hearing loss about 69 cases]

ABSTRACT

Sudden hearing loss is a typical otologic urgency. The pathophysiological mechanisms and the definition of sudden deafness are controversed. Several therapeutic diagrams were proposed for the management of this sensorineural urgency. But therapeutic results were not estimated to be efficient with conventional medical treatments. The purpose of the study The authors report this study to evaluate the efficiency of hyperbaric oxygen [HBO] on sudden hearing loss, to revise factor prognosis and finally to seek for clinical forms of sudden deafness in which HBO must be primary indicated. A retrospective study was performed on 69 patients with sudden deafness, treated by HBO after unfavourable evolution under conventional treatments In spite of the late time [20 days], fifty six percent of the patients had a satisfactory recovery. Efficiency of HBO was improved when it is practiced before the tenth day of the affection [92%]. Finally, this study shows an excellent systemic tolerance of HBO; since no severe incidents were recorded
