OBJECTIVE: Supracricoid laryngectomy with Cricohyoidoepiglottopexy (SCL-CHEP) is a functional organ preservation surgery for laryngeal cancers. Post-operative laryngeal function is generally promising. Some patients, however, cannot attain satisfactory functional results because of an excessively wide neoglottis resulting in an insufficient neoglottal closure. Autologous buccal fat augmentation was conducted to correct the insufficiency.
PATIENTS AND METHODS: Two patients underwent intervention. Under general anesthesia, autologous fat was harvested from the buccal fat pad. Fat tissue was injected into the widest plane of the neoglottis under direct laryngoscopy; a navigation system was incorporated to identify the responsible site. Acoustic, aerodynamic, and perceptual analyses along with videofluoroscopic swallowing study and screening questionnaires were used for functional evaluation.
RESULTS: A total of 0.8ml (Case 1) and 0.7ml (Case 2) of fat tissues were injected into the submucosal space of the responsible sites. Both patients experienced functional improvement subjectively after augmentation; psychological parameters for voice and swallowing also improved.
CONCLUSIONS: Buccal fat augmentation to correct insufficient neoglottal closure after SCL-CHEP was technically feasible. A navigation system was helpful for confirmation. Fat absorption occurred and one third of the volume remained at 3 and 6 months. Although, vocal measurements remained unchanged, psychological parameters for voice and swallowing improved.
