A Transcanal Endoscopic Approach for Management of Pulsatile Tinnitus due to High-Riding Dehiscent Jugular Bulb.

Pulsatile tinnitus (PT) caused by a high-riding dehiscence jugular bulb (HDJB) is a rare but treatable otology disease. There are several managements include transcatheter endovascular coil embolization, transvenous stent-assisted coil embolization, or resurfacing the dehiscent bony wall of high jugular bulb under the use of microscope. Among those options, surgical resurfacing of HDJB might be an effective and safe choice with less destruction. However, previous studies approached middle ear cavity via microscope can only provide a lateral, indirect view, while resurfacing the vessel through a transcanal endoscopic ear surgery (TEES) approach may give surgeon a direct and easy way to manage HDJB. In this report, we presented a case of 40-year-old woman with HDJB and shared our clinical consideration and reasoning of the surgical management of PT via a transtympanic approach by TEES rather than a transmastoid approach.
