Schwannoma is a benign well-encapsulated tumor arising from the sheath of Schwann cell. It is known to recur rarely after resection.

Since it is common at the head and neck region, schwannoma must be included in the differential diagnosis. It is common at the head and neck region but a few cases was reported in the larynx. We have experienced a 65-year-old woman who had 6-month history of progressive vocal change. We recognized a benign mass at supraglottic area on CT and MRI. The tumor was successfully removed through lateral thyrotomy approach. So we report this case of laryngeal schwannoma in a patient who recovered voice after surgery.
