“…Schwannomas were first identified by Virchow in 1908 and later reported by vercoy in 1910. 6 Neurogenic tumors of the head and neck arise from neural crest cells which differentiate into nerve sheath cells and sympathoblast. Schwannomas and neurofibromas arise from schwann cells.…”

Objectives• To evaluate the unusual sites of schwannoma considering its NOO. • To assess the accuracy of CT/FNAC findings with postoperative biopsy. • To assess the preoperative NOO and NOO on table. Materials a n d MethOdsTen patients with head and neck schwannomas who have been treated at our department in our institution (Hassan Institute of Medical Sciences, Hassan, Karnataka) between June 2006 and March 2020 were reviewed, and those cases were confirmed as schwannomas postoperatively.

“…Schwannoma was first identified by Virchow in 1908 and later reported by Verocay in 1910 [5]. Since that time, they have been called neurilemmomas, solitary nerve sheath tumours, perineural fibroblast tumours and, most recently, schwannomas, according to the World Health Organization (WHO) classification [6].…”

Schwannomas are benign neoplasms of the peripheral nerves originating in the Schwann cells. They are rare and usually solitary, with clearly delimited capsules. They occur in the head and neck region in only 25 % of the cases, and may be associated with Von Recklinghausen's disease. Schwannomas are always a diagnostic dilemma as they are asymptomatic for long time and histopathology is the gold standard for diagnosis. The present study retrospectively analysed data of 4 patients with schwannomas and reviewed the literature on the subject. Retrospective study at ENT & Head and Neck Surgery Department of Navodaya Medical College, Raichur. Data of 4 patients between 2008 and 2014 were reviewed. The sites of cervical schwannomas and the intraoperative, histopathological and postoperative clinical status of these cases were studied. Diagnostic methods, type of surgery and associated nerve of origin (NOO) were evaluated. The patients' age ranged from 18 to 50 years. None of them had type I neurofibromatosis or Von Recklinghausen's disease. The nerves affected included the brachial plexus, vagus nerve, sympathetic chain and lingual nerve. The nerve of origin was identified based on intra-operative findings and post-operative neurological deficits. Tumour was removed by debulk operation with the preservation of NOO method. Schwannomas are generally benign, and rarely recur. An accurate preoperative workup with the identification of NOO is very important not only for a correct diagnosis, but also for surgical planning and informing the patient about the possible complications.

Abstract: Schwannomas arise from neural crest derived Schwann cells. They are rare neoplasms intra-orally and account to 1% of the tumors of head and neck region. Involvement of posterior one third of tongue is even rarer, in incidence.
