Rare case of lingual nerve schwannoma of parapharyngeal space

Abstract

Schwannoma of parapharyngeal space is an uncommon benign tumour of head and neck region. These are slow-growing and usually well-encapsulated masses arising from Schwann cells of cranial nerves. The majority of schwannoma in parapharyngeal space arise from vagus; however, cases have been reported with origin from other cranial nerves. Complete surgical excision is the treatment of choice. We recently experienced a case of schwannoma arising in parapharyngeal space of lingual nerve origin which was treated by transcervical excision.
