Abstract

Pulsatile tinnitus of nonvascular origin is rare. We herein present a case of pulsatile tinnitus complicated with Jannetta surgery due to a communication created between the drilled mastoid cells and epidural space. She was successfully cured by otological surgery where the mastoid tip was packed with bone cement. A 68–year-old woman was referred to the previous hospital with complaints of right autophony, aural fullness, hyperacusis to her footsteps, and pulsatile tinnitus for the past three years. She had received Jannetta surgery for right hemifacial spasm seven years before. The computed tomography (CT) of the right temporal bone showed bony dehiscence between the mastoid cells and posterior cranial fossa. She underwent otological surgery to obliterate the tip of the mastoid cavity with artificial bone cement (BIOPEX) under general anesthesia. Her annoying aural symptoms were immediately abolished and she has been free from symptoms at ten months after surgery. It is critical to ensure the closure of any communication created between the middle ear and epidural space during surgeries in order to prevent the occurrence of pulsatile tinnitus.
