Englische Zusammenfassungen der Kapitel 1–9
ZusammenfassungAs a whole the effect of an explorative tympanoscopy with sealing the round/oval window(s) in cases of a profound idiopathic unilateral sudden hearing loss (ISSNHL) has been analyzed (data: own study cases and review of literature) and the results have been compared to that of intratympanal steroid injections published elsewhere. In detail the topics of the chapters focused on: Comparison of epidemiologic data, anamnestic and clinical findings including hearing results of our study group with those published Time course of hearing improvement after explorative tympanoscopyand sealing of the round/oval window Compilation of parameters influencing the extent of the initial hearing loss and the hearing gain after surgical therapy Perilymphatic fistulas as an etilogical factor causing a sudden profound hearing loss Comparison of those cases which have been treated by obliteration of the round/oval window with and without corticoid-soaked connective tissue Comparison of patients (data sampled by literature and own cases) treated with intratympanal corticoid injections on the one side or explorative tympanscopy with sealing of the round/oval window on the other side.
