A case of glomus tympanicum tumor

We report a case of glomus tympanicum tumor. A 65-year-old woman seen for right ear pain was found to have a dull red mass behind her right eardrum on otoscopic examination. The tumor was diagnosed as a glomus tympanicum tumor by computed tomography (CT) and magnetic resonance imaging (MRI). Preoperative angiographic findings revealed that this tumor was fed by the middle meningeal artery, which we embolized, and by more than one artery. The tumor was completely removed by transcanal tympanoplasty with only a small amount of bleeding. Bipolar coagulation can coagulate blood vessels and offers better visualization of the surgical field.
