OBJECTIVE: This study aimed to evaluate the effectiveness of pharyngeal flap surgery (PFS) for the management of velopharyngeal insufficiency in cleft lip/palate patients and to assess the impact of age at surgery, surgeon's skills, and postoperative speech therapy on the outcomes. METHODS: Prospective preoperative and postoperative assessments were performed on 240 patients aged 6 to 57 years using nasometry and pressure-flow studies.This study was carried out in a quaternary hospital.This study was superiorly based on PFS.Speech nasalance scores were assessed by nasometry and velopharyngeal orifice area assessed by pressure-flow technique, 2 days before and 1 year after PFS, on average. Differences were considered significant when P < 0.05. RESULTS: Significant reduction in nasalance scores was observed in 68% of the cases, and improvement of velopharyngeal area was observed in 66%. Rates of 55% and 48%, respectively, were observed when complete resolution was considered. Higher success rates were observed in children (81%) compared with other age groups analyzed and in patients who had concluded postoperative speech therapy (86%). Results did not differ among surgeons. CONCLUSIONS: Pharyngeal flap surgery was shown to be effective in reducing nasalance scores and velopharyngeal area during speech for a significant number of patients. Complete resolution was observed in smaller number of cases. Age at surgery and postoperative speech therapy were relevant factors for treatment success.
