Sudden @entity1274 is still a diagnostic and therapeutic dilemma and is very difficult to predict recovery in it. Different factors may influence a prognosis like severity of @entity393 , duration of symptoms before treatment, presence of vertigo, type of audiogram and age of @entity1 . The aim of the study was an evaluation of the hearing improvement in @entity2459 in relation to some of these elements. A retrospective analysis of 119 @entity1 treated for sudden @entity1274 during 10 years was done. Clinical otolaryngological, neurological and ophthalmological examination, audiologic and ENG tests were carried out. Hearing improvement was obtained in 51 @entity1 (43%). Hearing recovery was recorded in 38 @entity1 (66%) in whom duration of disease before treatment was no longer than 7 days, in 9 @entity1 (25%) with a period 8-14 days and in 4 @entity1 (16%)--with period 15-30 days (66% vs 25% vs 16%, p < 0.001, 25% vs 16% p = 0.39). Hearing improvement was more frequent in @entity1 with initially mild (51.6%) than severe (38.7%) and profound @entity393 (25%) (51.5% vs 25%, p < 0.05). Hearing recovery was observed in 18 @entity1 (33.3%) with vertigo and in 33 @entity1 (50.8%) without vertigo (p = 0.056). In analysis of age (five groups: until 30 years, 31-40 years, 41-50 years, 51-60 years, over 60 years) in comparison with hearing recovery it was not found any significance (45.5% vs 45.8% vs 46.4% vs 37% vs 38.9%, p = 0.94). It was stated that in @entity1 with @entity2459 before treatment and level of @entity393 may significantly influence an outcome, also vertigo may worsen a recovery, contrary age of the @entity1 does not seem as important prognostic factor.
