Abstract

OBJECTIVE:: To determine the prevalence of cochlear-facial dehiscence (CFD) and to examine the influence of otic capsule area, age, sex, and race on CFD. STUDY DESIGN:: Descriptive study of archived temporal bone specimens. MATERIALS AND METHODS:: Targeted sections from 1,020 temporal bone specimens were scanned and examined for CFD. Cochlear-facial partition width (CFPW) and otic capsule area (OCA), a marker of bone thickness, were measured using image analysis software. Demographic data were analyzed using multiple linear regression analysis. RESULTS:: The mean CFPW was 0.23?mm (range, 0–0.92?mm; SD, 0.15?mm). Six patients were completely dehiscent (0.59%). Fallopian canal width, age, sex, race, and OCA were found to be significant predictors of CFPW. Age was found to be negatively correlated with CFPW (β?=?−0.001) (p?
