what is a glomus tumor
Glomus Tumors (Tympanicum Jugulare). Glomus tumors are the most common benign tumors of the middle ear. They arise from glomus bodies. Glomus bodies are tiny, normal structures in the middle ear which serve as baro receptors.These baro receptors sense and help to regulate the oxygen pressure in the middle ear and mastoid.s glomus tumors expand, they begin to fill the middle ear. Some glomus tumors of the middle ear start by growing from the floor of the ear upward. These are the tumors difficult to distinguish from glomus jugulare tumors. A CT scan or other radiologic findings are needed in these cases.
