Analysis of Risk Factors for Velopharyngeal Insufficiency and Palatal Fistula After Sommerlad-Furlow Palatoplasty

Abstract

This study aimed to introduce a surgery technique-Sommerlad-Furlow palatoplasty (SFP) and analyze the risk factors of velopharyngeal insufficiency (VPI) and palatal fistula after SFP. Cases after SFP under the age of 5 between 2011 and 2021 were reviewed, and the cases with complete follow-up information were included. Univariate and multivariate logistic regression were used to evaluate the effects of surgical age, surgery technique, surgeon’s experience, and cleft type on velopharyngeal function and the occurrence of palatal fistula. SFP is a safe and effective procedure to increase the palatal length and reconstruct the levator veli palatini sling. The speech outcome after SFP was associated with cleft type and age at operation. Age = 1.285 years is the best cutoff value. The fistula occurrence was associated with cleft type only.
