Abstract
The glomus tumor is considered to be the most common of all tumors that involve the middle ear. This report defines the glomus tumor and discusses the symptomatology of the tumor with respect to the various developmental courses it may follow. Forty clinical cases of glomus tumor are reviewed, with emphasis upon the incidence of the tumor and its symptoms, including the audiological manifestations noted in this series of cases. Current medical management of the glomus tumor recommends surgical removal of the lesion when possible; however, irradiation and embolization of the tumor may also be considered when its invasion into surrounding structures has been extensive. The pathology and its treatment may have marked temporary or permanent effects upon the hearing of the patient, and the importance of ongoing audiological management is therefore emphasized.
