Abstract
-
Nerve sheath tumors are not frequent in the head and neck area. They might arise from large or small units of cranial, cervical and brachial plexuses as well as the cervical symphatic nerves. Their clinical course and findings are not similar, and preoperative diagnosis are extremely difficult in some cases. We experiencd eighteen cases of extracranial nerve sheath tumors in the head and neck regions during the past six years Twelve of them were schwannomas, and six of them were neurofibromas which did not associate with Von Recklinghausen's diseases. This analysis of eighteen cases and two representative cases are reported with literature review.
