Transoral endoscopic resection of a paraglottic space schwannoma: A case report and literature review

Paraglottic space schwannoma is a rare benign laryngeal tumor, and surgery of large lesions remains clinically challenging. We present a 59-year-old male with 10-year hoarseness diagnosed with left paraglottic space schwannoma (3.7 cm) and systematically review relevant literature to analyze its characteristics, diagnostic methods and surgical strategies. The patient underwent direct laryngoscopy with combined CO2 laser and microlaryngoscopic techniques. We summarize his clinical features, surgical process, pathological results and postoperative recovery. No local recurrence or residual lesion was observed during follow-up. Therefore, the transoral laser microsurgery is an effective, minimally invasive surgical option for large paraglottic space schwannomas (>3 cm), achieving complete excision with minimal trauma, less bleeding, rapid recovery and no cervical scarring.
