Abstract
We present series of head, neck extracranial non-vestibular schwannomas treated during 2-year period. All patients with head and neck schwannomas treated at our department from April 2007 to July 2009 were reviewed. There was female predominance (72%). The mean age at diagnosis was 38 years. All (100%) presented with a neck mass. Most common nerves of origin were the vagus and the cervical sympathetic chain. Treatment for all cases was complete excision with nerve preservation. Among all schwannoma patients, postoperative neural deficit occurred in four with partial to complete resolution in three. The follow-up period was 24 months. Non-vestibular extracranial head and neck schwannomas most frequently present as an innocuous longstanding unilateral parapharyngeal neck mass. Preoperative diagnosis may be aided by fine-needle cytology and magnetic resonance imaging or computed tomographic imaging. The mainstay of treatment is complete intracapsular excision preserving the nerve of origin.
