Glomus tumors are extreme vascular tumors and originated from the glomus bodies (chemoreceptor of neural origin ). They represent the most common benign neoplasm of the middle ear. The objective of this study is to analyze prospectively all pacients submitted to surgical treatment for glomus. We analyzed sex, age, clinical aspects, type of surgical access and the postoperative complications of 13 patients treated from august/97 to august/99. The mean age was 45,57 years and all were female. Five (5) patients (38.46%) had glomus tympanicum and 8 (61,53%) had glomus jugulare tumors. Among patients with tympanicum tumors, 80% had conductive hearing loss and 60% pulsatile tinnitus. The surgical access was endaural in 40%, wall up mastoidectomy in 40% and wall down mastoidectomy in 20%. One patient developed facial paralysis and profound sensorineural hearing loss. Among patients with jugulare tumors, 100% had hypoacusia (sensorineural hearing loss in 62,5%), 50% pulsatile tinnitus, and 50% other cranial nerve deficits , the infratemporal surgical access was used in all patients and the main complications were deficit of cranial nerves (50%), meningitis and liquoric fistulae (12,5%). Glomus tumors present good answer to surgical treatment and should be treated as soon as possible.
