Parapharyngeal neurilemmoma of the hypoglossal nerve
Abstract:
Although neurilemmomas are uncommon cervical neoplasms, they account for a significant percentage of parapharyngeal space tumors. These neoplasms may originate from any nerve traversing this space, but the vast majority arise from the vagus nerve and sympathetic chain. Satisfactory treatment of neurilemmomas consists of total excision which is best accomplished via an external approach. Immediate nerve grafting is advocated when a segment of cranial nerve must be sacrificed in order to achieve complete tumor removal. A case of a parapharyngeal neurilemmoma arising from the hypoglossal which required treatment in this manner is presented. Electromyographic studies performed 15 months postoperatively demonstrate reinervation of the lingual musculature via the nerve graft.
