Medialization Laryngoplasty Implant Complication: Endolaryngeal Extrusion

[摘要] Background: In this case study, we describe a late complication of a Montgomery® medialization thyroplasty that has not been previously reported, and the surgical approach used for its intervention. Case Report: A 57-year-old gentleman who underwent a medialization laryngoplasty with a Montgomery® implant 3 years previously to treat idiopathic left sided vocal fold paralysis presented with sudden dysphonia following a robust coughing fit. His implant was observed extruding into the endolaryngeal lumen. Revision surgery consisted of implant removal through a transcervical approach and reconstructing the paraglottic space with fibrin glue (Tissel®) and an autologous free fat graft. Post-operative airway and voice outcomes were excellent, and the patient was decannulated prior to discharge. One-month post-operative voice outcomes were modest [Voice handicap index (VHI)-10 = 30]. Conclusion: This report describes a previously unreported complication of medialization thyroplasty of an intraluminal extrusion of a Montgomery implant and a novel surgical approach for repair.
