Neural infiltration of glomus temporale tumors.

Biologic behavior of glomus temporale tumors in relation to cranial nerve infiltration remains unclear. An analysis of cranial nerve involvement in relation to tumor staging was undertaken in a series of 102 glomus temporale tumors. Frequent neural infiltration was noted to occur in large glomus tumors, and a grading system of infiltration with both pathologic and surgical relevance introduced.
