Dysphagia caused by giant schwannoma of the supraglottic oropharynx: A case report and review of the literature

Schwannomas are benign, encapsulated, peripheral nerve tumours that arise from the Schwann cell. Approximately 25%–45% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck. However, schwannoma of the supraglottic oropharynx is rare. We report on a 35-year-old female who complained of progressive dysphagia, from whom a large schwannoma in the supraglottic oropharynx was excised through a transoral approach. No recurrence was seen after one year follow-up. Although rare, schwannomas do occasionally occur in the supraglottic oropharynx. When dysphagia is present, a thorough diagnostic procedure should be performed to evaluate the morphology and function of the upper aerodigestive tract. MRI is sensitive and specific in the diagnosis of schwannoma. And the best treatment of choice is complete excision with preservation of functions. •Schwannoma is a benign peripheral nerve tumor that usually presents as a slow growing single lesion.•Giant schwannoma of the supraglottic oropharynx is rare.•The main symptom is dysphagia due to the location and mass of the tumor.•MRI is particularly helpful in delineating schwannoma.•Surgery is the treatment of choice.
