Two Cases of Glomus Jugulotympanicum

Glomus jugulotympanicum is a slow growing tumor originating at the dome of jugular bulb. It is histologically benign, but can have an aggressive clinical course with involving neurovascular structures at the skull base and extending through dural barrier. The primary treatment of glomus jugulotympanicum is total surgical extirpation. However, it can cause injury of cranial nerves and major vessels at the cranial base. We present two cases of glomus jugulotympanicum and reviewed the surgical techniques with special emphasis on the manipulation of facial nerve and postoperative cranial nerve palsy.
