Abstract

|
|
Glomus tympanicum tumors are a rare type of middle ear tumor that often present with symptoms such as pulsatile tinnitus, hearing loss, and ear fullness. Vestibular schwannomas are benign tumors of the cerebellopontine angle that can cause hearing loss, tinnitus, and vertigo. Although cases of both tumors occurring on the same side have been reported, only a few cases of contralateral glomus tympanicum tumors associated with vestibular schwannomas have been documented. We present a case of a 69-year-old female who was diagnosed with a vestibular schwannoma on the left side and a glomus tympanicum tumor on the right side. The patient underwent transcanal endoscopic ear surgery (TEES) for the removal of the glomus tympanicum tumor. This case emphasizes the importance of careful examination of both ears. And we suggest that TEES may be a viable option for treating early-stage glomus tympanicum tumors.
