Objective:
To study effective operation method of congenital velopharyngeal insufficiency by reviewing clinical data of 29 patients with pharyngoplasties.
Methods:
29 patients (9 male and 20 female, ranged from 4 to 25 years old, mean age was 13.5) with congenital velopharyngeal insufficiency were available for this study. All cases received Chinese speech intelligibility test and blowing test before and after the pharyngeal flap surgery.
Results:
Chinese speech intelligibility of 29 cases who underwent pharyngoplasties was improved from 33.86% to 43.13%, and the blowing time was increased from 4.60 to 17.72 seconds, the degree of abnormal speech was reduced.
Conclusion:
The pharyngeal flap surgery is an effective method for congenital velopharyngeal insufficiency, which reduces hypernasality and increases oral pressure, improves the velopharyngeal function.
