Abstract

Schwannomas are benign, slow-growing, encapsulated tumours deriving from the peri neural cells located in the nerve sheath. They can arise from any peripheral, cranial or autonomic nerves, and show a predilection for the head and neck region. Extra cranial Head and Neck schwannomas are rare tumours. They may produce secondary symptoms like nasal obstruction, dysphagia, and hoarseness of voice depending upon the location of the tumour. The preoperative diagnosis is difficult. Although preoperative imaging or fine needle aspiration cytology may help to reveal diagnosis, they are inadequate. The definitive diagnosis is made by histopathological examinations.
