Temporal Bone Posterior Wall Defect, a New Clinic Entity?

Objective: To define clinical and audiological findings in patients with temporal bone posterior wall defects (TBPWD) and to investigate possible relationships between these findings and the characteristics of the defect.

Materials And Methods: The computed tomography (CT) views of 1198 patients with vestibulocochlear symptoms between 2007 and 2012 were retrospectively evaluated, and TBPWD and associated anomalies were investigated. Patients who had TBPWD were called back, and clinical and audiological examinations (tympanometry, pure tone audiometry, acoustic reflexes, and otoacoustic emission) were performed.
