Abstract

The 35 cases of neurogenic tumors in the head and neck were treated in recent 15 years. 35 patients, 13 males and 22 females, ranging in age from 8 to 71 years, had extracranial solitary neurogenic neoplasms. The nerve involved were vagus nerve in 4, cervical plexus in 3, cervical sympathetic plexus in 2, chemodectoma of carotid bifurcation in 2, olfactory epithelium in 2, 6 other nerves, and unknown in 20. Treatment was surgical excision in 29, enucleation in 2, biopsy in 1. Patients with malignant lesions had radical resection or combination of wide resection and postoperative irradiation or chemotherapy. Biopsy only is given in one of the chemodectoma of carotid bifurcation. There was no evidence of tumor growing. Local recurrence has been found in two patients. One has a tumor originated from the cervical sympathetic trunk (120×42mm). Because the vertebrae and muscles were invaded, the tumor was resected patialy. Since the second operation, there was no evidence of tumor growing. Other has a tumor in the parapharyngeal space and the recurrent tumor was removed by a cervical-transpharyngeal midline mandibulotomy. There was no evidence of recurrence since the second eperation. On condition that strict follow-up is possible and there is no evidence of tumor growing, tumors are not always required for surgical resection.
