All participants were submitted to basic audiological evaluation. transient and distortion product otoacoustic emmisions(TEOAEs and DPOAEs), vestibular assessment including history taking, office tests and videonystagmography(VNG) and dermatological assessment to determine type, percent of body surface area involvement and duration of vitiligo.Results: This study showed statistically significant difference between control and study groups in pure tone audiometry(PTA) and otoacoustic emissions results. Fitfty percent of vitiligo patients had peripheral vestibular disorders(10 vestibulhar neuritis and 5 posterior canal benign paroxysmal positional vertigo.Conclusion: The results in this study showed that 50% of vitiligo patients suffered from peripheral vestibular disorders in addition to auditory affection. Vitiligo patients require routine monitoring for auditory and vestibular functions for early identification and monitoring of changes as the disease progress.展开更多

Study Design: Prospective study of 35 cases of BPPV. Materials and Method: 35 patients of BPPV presenting at vertigo clinic of ENT department at Civil Hospital Ahmedabad were treated with canalolith repositioning procedure and improvement in nystagmus was studied and confirmed by VNG. Observation: 31 patients out of 35 patients were improved with 1st CRP, 2 out of 3 patients improved with 2nd CRP and 1 patient improved with 3rd CRP. This improvement is confirmed using VNG. Conclusion: Videonystagmography is a very useful tool for ensuring the otolith repositioning by the canalith repositioning manouver. It is a confirmatory adjunct to visual analysis.展开更多
