Schwannoma is a benign slow growing nerve sheath tumor that is typically encapsulated and composed of well-differentiated schwann cells. Schwannomas may take origin from different nerves such as cranial, spinal nerves, and the sympathetic chain. Approximately 25% to 45% of all occur in the head and neck only 1% of them are located in the oral cavity. However, it is quite rare to for schwannomas to form on the tongue base. Ancient schwannoma is the rarest, and also extremely rare in oropharynx. A 32-year-old female patient was admitted to our clinic with complaints of hoarseness, difficulty in swallowing, throat pain, snoring, and dyspnea. In examination, a smooth surfaced circumscribed mass, which originated from the tongue base was observed. In the magnetic resonance imaging, a 4.5 × 3 cm sized tongue base mass which narrowed the upper airway was detected. An endoscopic transoral excisional biopsy was performed. The histopathological diagnosis was determined as ancient schwannoma. The use of the endoscopic transoral approach can be suitable to protect the important anatomical structures, functions, and reduce the complications and esthetic concerns for the resection of tongue base schwannomas.
