Abstract: OBJECTIVE:To demonstrate the regularity of velopharyngeal function recovery after primary cleft palatoplasty and its correlation with different surgical procedures, ages, cleft types, and follow-up times.
METHODS:Patients with cleft palate under 5 years old who had more than two follow-up records were included in this study, and consecutive evaluations of postoperative velopharyngeal function were performed. Univariate and multivariate logistic regression analysis were used to reveal the regularity of postoperative velopharyngeal function and the possible influencing factors.
RESULTS:A total of 165 patients were included. Inconsistent functions of the velopharyngeal closure were observed in 31 patients, of which velopharyngeal insufficiency (VPI) in the first follow-up converted to velopharyngeal competence (VPC) in the second follow-up, accounting for 18.79% of the total, and 134 patients had consistent velopharyngeal function. The patients in the group who had consistent velopharyngeal function were younger than those in the group who were inconsistent, and the differences between the two groups were statistically significant. The younger the operation age, the patient's velopharyngeal function was more likely to stabilize at the first follow-up. At the time of the first follow-up in 15, 28, and 40 months, the probability that the patients had stable postoperative velopharyngeal function was 80%, 90%, and 95%, respectively.
CONCLUSIONS:The recovery of velopharyn-geal function after surgery is a dynamic process. The velopharyngeal status of patients can be converted from VPI to VPC. Meanwhile, VPC cannot switch to VPI. The follow-up time is the most important factor affecting the consistency of the evaluation of velopharyngeal function. Choosing appro-priate follow-up time is the key to obtain the stable evaluation of velopharyngeal function.
