Abstract Introduction: Injection laryngoplasty is an effective surgical procedure for the treatment of glottic insufficiency. The introduction of the technique via flexible endoscopy (Flexible Endoscopic PhonoSurgery, FEPS) enables the procedure to be performed under local anesthesia, achieving results comparable to those obtained under general anesthesia while reducing operative time and associated costs. Among the various injectable materials, autologous fat shows excellent outcomes in terms of biocompatibility and durability. The aim of this study is to analyze the vocal outcomes of this procedure. Materials and Methods: This is a single-center retrospective study conducted on 146 patients at the Voice Center of “M. Bufalini” Hospital in Cesena from 2019 to 2024. Endoscopic parameters, perceptual measures (GRBAS scale, maximum phonation time, MPT), and subjective assessments (pre/post-intervention comparative self-evaluation, CSAD) were evaluated. Results: A statistically significant correlation was observed between incomplete glottic closure and increased preoperative GRBAS scores (p = 0.007). Multivariate analysis identified two variables most strongly associated with vocal improvement: injection in the mid-posterior third of the affected vocal fold (p = 0.004) and the presence of preoperative incomplete glottic closure (p = 0.006). MPT showed limited statistical significance, being higher in patients with preoperative vocal fold mobility (p = 0.03). CSAD confirmed good agreement between objective findings and subjective patient perception. Conclusions: Injection laryngoplasty with autologous fat performed via FEPS proves to be an effective technique for the treatment of glottic insufficiency, including in patients who are not suitable candidates for general anesthesia. Injection into the mid-posterior third of the vocal fold is associated with better functional outcomes.
Abstract Introduzione: La laringoplastica iniettiva rappresenta una procedura chirurgica efficace nel trattamento dell’insufficienza glottica. L’introduzione della metodica tramite endoscopia flessibile (Flexible Endoscopic PhonoSurgery, FEPS) consente l’esecuzione in anestesia locale, con risultati sovrapponibili alle procedure eseguite in anestesia generale e riduzione di tempi di intervento e costi associati. Tra i vari materiali utilizzabili per l’iniezione, il grasso autologo presenta ottimi risultati in termini di biocompatibilità e durata. Obiettivo del presente lavoro è l’analisi degli esiti vocali di tale procedura. Materiali e Metodi: Studio retrospettivo monocentrico condotto su 146 pazienti presso il Voice Center dell’Ospedale “M. Bufalini” di Cesena, dal 2019 al 2024. Sono stati valutati parametri endoscopici, percettivi (scala GRBAS, tempo massimo fonatorio, TMF) e soggettivi (autovalutazione comparativa pre/post-intervento, CSAD). Risultati: È stata osservata una correlazione statisticamente significativa tra una chiusura glottica incompleta e un punteggio GRBAS aumentato nel preoperatorio (p=0,007). Dall’analisi multivariata, le variabili maggiormente correlate al miglioramento vocale sono state la sede d’iniezione nel terzo medio-posteriore della corda vocale affetta (p=0,004) e la presenza pre-operatoria di una chiusura glottica incompleta (p=0,006). Il TMF ha riportato una significatività statistica limitata, risultando più elevato nei pazienti che presentavano pre-operatoriamente una corda vocale mobile (p = 0,03). Il CSAD ha confermato una concordanza tra i risultati oggettivi e la percezione soggettiva del paziente. Conclusioni: La laringoplastica iniettiva con grasso autologo in FEPS si conferma una tecnica efficace nel trattamento delle insufficienze glottiche, anche in quei pazienti non candidabili ad anestesia generale. L’iniezione nel terzo medio-posteriore della corda vocale risulta associata a migliori esiti funzionali.
