We present a rare case of schwannoma of the supraglottic larynx in a 30-year-old woman with a 5-year history of dysphonia. Excision of the mass was performed by transoral robotic surgery (TORS) without complication using the robotic da Vinci Surgical System, 0-degree three-dimensional endoscope, 5-mm microinstruments compatible with the da Vinci robot, and an FK retractor. Transoral robotic surgery rendered good exposure that allowed complete tumor resection. An external approach and tracheotomy were not necessary in this case. We found that TORS was practicable, efficient, and nonhazardous for the resection of a supraglottic schwannoma. We propose TORS for the treatment of large benign and selected malignant laryngeal tumors.
