Abstract
We herein report a case of a glomus tympanicum tumor occurring in a 57-year-old female who presented with right pulsatile tinnitus and hearing loss. An otoscopic examination revealed a reddish mass in the tympanic cavity through the tympanic membrane. Myringostomy was performed and severe bleeding was observed. The CT and MRI findings showed a tumor occupying the mesotympanium. The angiographic findings revealed the tumor-feeding artery to be the ascending pharyngeal artery. The tumor was completely resected using a transmetal approach without embolization. In order to resect the tumor safely utilizing this approach, it was important to secure a broad working space in the middle ear using extended standardized incisions of the meatal skin. The micro bipolar coagulater was therefore found to be very useful for controlling blood loss.
