Abstract
|
|
|
|
Glomus tympanicum tumors, are benign tumors of neural crest cell origin. They can spread throughout the mesotympanum, hypotympanum, and mastoid causing symptoms of pulsatile tinnitus, conductive hearing loss. The surgical approach is determined by the extent of tumor involvement in the mesotympanum, hypotympanum, and mastoid. A transcanal or postauricular approach with the operating microscope is the traditional means used to surgically manage middle ear paragangliomas. Transcanal endoscopic ear surgery, an emerging minimally invasive approach that offers superior visualization of the middle ear cleft. We experienced a case of glomus tympanicum tumor in 77 year-old female with several year-history of intermittent pulsatile tinnitus and earfullness which was surgically removed through Transcanal endoscopic approach.
