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

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

[Labyrinthine fistula - about 14 cases]

Labyrinthine fistulae constitute a potentially severe complication of cholesteatoma, because of its consequences on cochleovestibular function and of the association with other possible complications. A retrospective analysis has been conducted on 14 fistulae due to cholesteatoma. Fistula was often limited and involved semi circular external canal in all cases. Open technique with removal of the cholesteatoma matrix was performed for all patients. After 2 years of follow up, the outcome was favourable for 12 patients except 2 cases of cholesteatoma recidive. Audition still unchanged in 64% of cases. Surgical management of labyrinthine fistulae is controversial. General and local conditions as well as fistula aspects make every case particular, and the choice of the best surgical technic is necessary for the therapeutic results
