Endoscopic CO2 Laser Resection Using the Inversion Technique in 22 Combined Laryngoceles

Abstract

ObjectiveTo demonstrate the feasibility of transoral resection of, even large, combined laryngoceles by endoscopic CO2 laser resection using the inversion technique.MethodsA retrospective study over a 25‐year period of 20 patients with 22 combined laryngoceles. All patients were operated on using the CO2 laser inversion technique. Pre‐ and postoperative computed tomography (CT)‐scans or magnetic resonance (MR) imaging were available in all patients.ResultsThere were no surgical problems during all procedures. One patient required a tracheotomy pre‐operatively due to a compromised airway. All procedures were without intraoperative complications. Postoperatively, there were two complications: one hemorrhage, and one patient developed a granuloma with airway compromise. In two patients, residual disease was detected on postoperative imaging. One of them was re‐operated several years later due to the progression of this residual external component of the laryngocele. One patient had a non‐significant small internal laryngocele recurrence. The recurrence rate in this series was 2/22 (9.1%). The majority of patients (15/20) could be discharged from the hospital the day after surgery.ConclusionThe results of this study show excellent control of combined laryngoceles using the CO2 laser inversion technique, with a short hospital stay and a low rate of complications and recurrence. Even in large combined laryngoceles, CO2 laser excision using the inversion technique should be considered.Level of Evidence4 Laryngoscope, 133:2742–2746, 2023
