 Abstract
- Endolymphatic sac decompression (ESD) is indicated in intractable Meniere’s disease patients with serviceable hearing. A 43-year-old man presented with recurrent vertigo and fluctuating right hearing loss that had been intractable to medical treatment. ESD was performed for the purpose of vertigo control with hearing preservation. Positional vertigo with profound hearing loss developed immediate after surgery and positional vertigo was resolved within days. Following paralytic vestibulopathy with positive sign on head thrust test also resolved after 2 weeks, while sensorineural hearing loss was not recovered to preoperative level during 1 year of follow up. Recurrent vertigo attacks were developed again 1 year after the operation. Hearing preservation was not always guaranteed in ESD. Furthermore, chance of hearing loss should be included in informed consent though the procedure is purposed for hearing preservation.

Abstract

- Canal paresis in patients with benign paroxysmal positional vertigo (BPPV) has been variously reported from 26 to 50%. In such cases, BPPVs are developed secondary to accompanying vestibulopathy or other underlying inner ear diseases. Also the side of canal paresis is regarded as involved ear in the lateralization of horizontal canal BPPV (HC-BPPV), in which lateralization is sometimes ambiguous just by Eward’s second law. In this case, authors report a woman who had HC-BPPV and pathologic canal paresis which resolved after canalith repositioning. This case may imply that dislodged particles block the endolymphatic flow resulting canal paresis.
