Transcanal Endoscopic Ear Surgery for The Management of Pediatric Perilymphatic Fistula Caused by Trauma

Abstract

Perilymphatic fistula (PLF) is caused by leakage of perilymph through an abnormal communication between the inner and middle ear. Conservative treatment is considered in the initial stages; however, exploratory tympanotomy is performed if hearing does not improve or if dizziness persists. Transcanal endoscopic ear surgery (TEES) is considered an appropriate treatment option and is gaining popularity. We report a rare case of traumatic PLF in a 7-year-old male patient, in whom pneumolabyrinth without temporal bone fracture was diagnosed and treated by exploratory tympanotomy using TEES, and review the related research to discuss the usefulness of management using TEES for PLF.
