Glomus jugulotympanicum paraganglioma is a glomus jugulare paraganglioma that has spread superiorly to involve the middle ear cavity. The term can also be used clinically when a suspected glomus tympanicum paraganglioma involves the hypotympanum as its inferior extent cannot be established clinically 1.
As glomus tympanicum paraganglioma usually does not erode the floor of the middle ear, glomus jugulotympanicum paraganglioma should be the main consideration under these circumstances 2.
