OBJECTIVE: We reviewed the clinical and radiological features of 73 cases of trigeminal neuromas treated with radical surgery. METHODS: The records for 73 patients with trigeminal neuromas who were surgically treated in the neurosurgery department of King Edward VII Memorial Hospital and Seth Gordhandas Sunderdas Medical College (Mumbai, India), between 1989 and 2001, were retrospectively analyzed. The appropriateness of the selected surgical route was studied. The postoperative and follow-up data for the patients were analyzed, to determine the outcomes of radical surgery. RESULTS: In addition to the other presenting features of trigeminal neuromas, nine patients presented with the rarely reported symptom of pathological laughter. Three approaches were observed to be appropriate for treatment of these tumors, i.e., the infratemporal fossa interdural approach, the lateral basal subtemporal approach, and the retrosigmoid approach. In 51 cases (70%), total tumor excision was achieved. Two patients died during the postoperative period. With an average follow-up period of 38 months, there has been a recurrence in 1 case and 71 patients are leading independent and active lives. CONCLUSION: Radical surgery is associated with excellent clinical outcomes and long-term tumor control. A majority of tumors, even those that are large and multicompartmental, can be removed in a single surgical stage and exposure.
