title: [Vertigo and objective vestibular symptoms in computer analysis of ENG in otosclerotic patients and after stapes operations].
abstract: The aim of this paper was evaluation of vertigo frequency in otosclerotic patients (group I N = 64) in comparison with control group (group II N = 20) and in people after stapedectomy (group III N = 64). Furthermore electronystagmographic recording spontaneous nystagmus, positional nystagmus were made. Computer analyses of ENG-recording and automatic calculation of directional preponderance and canal paresis were used. Vertigo was in 12% otosclerotic patients while in equal of age control group only in 5% subjects. Spontaneous nystagmus in 20% and positional nystagmus in 27% were recorded in otosclerotic patients while that took place in 10% and 15% control group respectively. Asymmetric reaction in-group I was in 21% cases and in 10% subject's in-group II. Real directional preponderance was in 18.8% otosclerotic patient's in-group I and it was absent in-group II. Obtained results revealed existence vestibule disturbances in otosclerotic patients. More frequent labyrinth objective symptoms were registered post stapedectomy. Vertigo in 21%, spontaneous nystagmus in 58%, positional nystagmus in 61%, asymmetric reaction in 48% was noted. Marks of vestibule and organ injury in otosclerosis and post stapedectomy were met. Vestibule disturbances were irritate and inconstant character. It is appears to be needed examination of balance system before stapedectomy in the planning of stapes operation and after operation on stapes. Presence of vestibular symptoms after stapes surgery is not cause less post stapedectomy improvement of hearing but sometimes postoperative improvement of hearing is better for lower frequencies in patients group with vestibular disturbances than in-patients without these symptoms.
