A rare case of bilateral vagus nerve schwanomatosis.

Schwanomatosis is the third most common form of neurofibromatosis. Schwanomatosis affecting the vagus nerve is particularly rare. In this report, we describe an extremely rare case bilateral vagus nerve schwanomatosis in a 45-year-old male patient. The patient initially presented with bilateral neck tumors and hoarseness arising after thoracic surgery. We performed left neck surgery in order to diagnose and resect the remaining tumors followed by laryngeal framework surgery to improve vocal cord closure and symptoms of hoarseness. Voice recovery was successfully achieved after surgery. An appropriate diagnosis and surgical tumor resection followed by phonosurgery improved patient quality of life in this rare case.
