Abstract

Deep cervical schwannomas are rare benign tumors originating from Schwann cells, and vagal nerve involvement is exceptional. We report the case of a 30-year-old woman presenting with progressive dysphagia and mild pharyngeal discomfort. Cervical MRI revealed a well-defined right parapharyngeal mass displacing the carotid artery anteriorly and the internal jugular vein posteriorly, suggestive of a vagal schwannoma. The tumor was completely excised through a combined transcervical and transparotid approach, with preservation of the main vagal trunk. The postoperative course was uneventful, with no neurological deficit. Histopathologic examination confirmed a benign vagal schwannoma. After six months of follow-up, the patient remained asymptomatic with no evidence of recurrence. This case highlights the importance of early diagnosis, precise preoperative imaging, and meticulous microsurgical dissection to ensure functional nerve preservation and optimal surgical outcomes.
