Abstract
OBJECTIVE: To study the objective acoustic assessment and aerodynamic assessment of pediatric patients after tonsillectomy with or without adenoidectomy. STUDY DESIGN: Prospective cohort study. METHODS: Pediatric patients who had received tonsillectomy in our department since 2011 October to 2012 September were selected as study objects. The acoustic analysis was performed by the Multi-Dimensional Voice Program and aerodynamic examination was performed by Phonatory Aerodynamic System. The preoperative and postoperative (1 month after surgery) data were compared. RESULTS: The postoperative acoustic index had no obvious change compared with the preoperative data. Among the aerodynamic index, postoperative maximum phonation time prolonged and postoperative subglottal pressure decreased comparing with preoperative index. CONCLUSIONS: From the aerodynamic point of view, tonsillectomy with or without adenoidectomy plays a positive role in the improvement of voice production.
