Superior canal dehiscence syndrome: clinical manifestations and radiologic correlations

The objective of this study is to describe the superior canal dehiscence syndrome (SCDS) and its vestibule–cochlear manifestations, while analyzing dehiscence size, audiogram and vestibular-evoked myogenic potential (VEMP) changes following dehiscence obliteration. We conducted a prospective study i...

Description
Summary:The objective of this study is to describe the superior canal dehiscence syndrome (SCDS) and its vestibule–cochlear manifestations, while analyzing dehiscence size, audiogram and vestibular-evoked myogenic potential (VEMP) changes following dehiscence obliteration. We conducted a prospective study in a tertiary referral center. All Patients diagnosed and surgically treated for SCDS were operated through a middle fossa craniotomy (MFC). Clinical and radiological data were collected. The main outcome measures were Air-bone gaps, Pure-tone average (PTA), speech discrimination scores (SDS) and VEMP thresholds and were correlated to dehiscence size. 28 patients were included in this study with a mean dehiscence size of 4.68 mm. Phonophobia and imbalance were the most debilitating cochlear and vestibular symptoms, respectively. At 2 months postoperatively, low-frequency air-bone gaps showed a statistically significant improvement ( p
