Abstract

A stapedial dislocation is a rare complication of ossicular trauma that is most commonly caused by direct, penetrating injury to the external ear canal. In this type of ossicular dislocation, patients usually suffer from cochleovestibular symptoms including progressive sensorineural hearing loss, conductive hearing loss, tinnitus, and vertigo. We present rare cases of internal stapedial dislocation after penetrating trauma, which resulted in the preservation of bone conduction hearing thresholds and complete resolution of the vestibular symptoms after an urgent repair. We have also reviewed the literature to determine the optimal management of stapedial dislocations.
