Glomus tympanicum and Glomus jugulare, also known as jugulotympanic paraganglioma: Both commonly present as a middle ear mass resulting in tinnitus (in 80%) and hearing loss (in 60%). The cranial nerves of the jugular foramen may be compressed, resulting swallowing difficulty, or ipsilateral weakness of the upper trapezius and ...
A glomus tumor (also known as a "solitary glomus tumor" [1]) is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot. [2]: 670 They account for less than 2% of all soft tissue tumors. [3] The majority of glomus tumors are benign, but they can also show malignant features. [4]

Glomus jugulare tumor: A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves. A glomus jugulare tumor grows in the temporal bone of the skull, in an area called ...

Benign tumors involving the hypoglossal nerve and canal include large glomus jugulare neoplasms. Malignant tumors revolving around the hypoglossal canal can include metastases, myeloma, neural tumors such as neuroma and schwannoma; meningioma can also occur occasionally.

Neurotology is expanded to include surgery of the lateral skull base to treat intracranial tumors related to the ear and surrounding nerve and vascular structures, such as large cerebellar pontine angle acoustic neuromas, glomus jugulare tumors and facial nerve tumors. Some of the concerns of otology include:
