Abstract
Various surgical approaches for the treatment of laryngeal submucosal tumors have been reported. Endoscopic excision is indicated for small lesions, while external approaches are recommended for larger tumors. This report introduces a supra-thyroid alar cartilage approach (STACA), which has strong advantages for the preservation
of the laryngeal framework and voice recovery after surgery. Case series with chart review. Four patients with laryngeal submucosal tumors in the paraglottic space underwent complete tumor removal through STACA. Medical charts were reviewed to evaluate patient background, major complaints, tumor type, tumor size, the time period from operation to tracheostomy closure, tumor recurrence, and the difference between pre- and postoperative voice quality. Voice quality was assessed using the GRBAS score, maximum phonation time (MPT) and Voice Handicap Index-10 (VHI-10) 6 months after surgery. All patients were females between 43 and 67 years of age. Two patients had schwannoma, one laryngocele, and one lipoma. Mean tumor size was 3.4 cm. The main complaints were hoarseness in all patients, and dyspnea in one. The periods of time from surgery to oral intake and tracheostomy closure were 3.5 and 7 days, respectively. No patient developed recurrence during a minimum follow-up period of 2 years. The postoperative GRBAS scores, MPT and VHI-10 improved in all patients. STACA has advantages including minimal trauma, no deformity to the laryngeal framework, and good voice qualities after the resection of laryngeal submucosal tumors.
