Abstract

Extracranial schwannomas of the head and neck domain are rare neoplasms. Most of the time, these tumors occur as asymptomatic neck swellings which masquerade as cervical lymphadenopathy, carotid body tumors, bronchial cyst, and vallecular cyst. We present 10 cases of head and neck schwannomas that have been treated and followed up between June 2006 and March 2020 in the Department of Otorhinolaryngology of Hassan Institute of Medical Sciences, Hassan, Karnataka State, India. These patients have been retrospectively reviewed. The main aim of the study is to know the nerve of origin (NOO) preoperatively and on the table. Also to know the unusual sites of schwannoma in the head and neck domain. The age-group between 10 and 50 years and female predominance of 60%. Seven patients presented with neck swelling and three patients with pressure symptoms. Preoperative diagnosis is mainly on clinical suspicion. Radiological imaging like CT scan/MRI may be helpful in diagnosis. FNAC is an adjunctive tool for diagnosis. Among 10 patients NOO could make out in seven patients. Three from the sympathetic, three from the vagus, and one from the internal laryngeal nerve. In three patients, NOO could not make out. Intracapsular dissection of the tumor with preservation of the NOO is the most recent common modality of treatment. Neurological deficit after tumor excision is common in large tumor excision. Early recognition and treatment are best for the preservation of NOO.
