We investigated 315 patients with idiopathic sudden deafness treated at our hospital between 1992 and 1997. Statistical analysis of the clinical data from these cases revealed several findings concerning the hearing prognosis. Prognostic factors for significantly better hearing were as follows: younger age, absence of vertigo, hearing loss configuration of low tone sudden deafness and trough type sudden deafness, mildness of the initial hearing loss and initial visit during the first one or two weeks after the onset.
Therapeutic effects on the hearing improvement were as follows: defibrinogenation therapy was as effective as steroid therapy. No significant difference could be observed in efficacy between treatments with and without stellate ganglion block (SGB), but the therapy was considered useful to some extent. With regard to the hyperbaric oxygen therapy (OHP), there was no significant difference in efficacy of treatments with and without OHP. Since the number of cases without OHP was small, additional studies are needed.
