Abstract
Introduction:
The purpose of the present study was to investigate various factors of cleft palate and to analyze their effect on fistula occurrence following palatal muscle repair using intravelar veloplasty.
Methods:
A retrospective review of patients who underwent palatoplasty was performed. Primary palatoplasty was performed by a single surgeon in a single center. A total of 165 patients who underwent palatoplasty were enrolled. Primary palatoplasty with levator veli palatini muscle repair using intravelar veloplasty was performed. Three extrinsic factors (age, gender, and body weight) and 6 intrinsic factors (cleft width, ratio of cleft width to intermaxillary tuberosity distance, cleft anterior margin shape, uvula position, cleft lip, and radical intravelar veloplasty) were analyzed.
Results:
Palatal fistula occurred in 11 (6.67%) patients. The occurrence of fistula was significantly correlated with a specific Veau classification, that is, type II (P = .041). Fistula tended to occur more frequently with a wide cleft palate (P = .063), and the high-risk cutoff value of the width was 7.75 mm.
Conclusions:
A larger cleft width tended to increase the occurrence of fistula. Close observation and information about the higher risk of fistula formation should be given to patients with a large cleft width who underwent intravelar veloplasty.
