Longitudinal evaluation of articulation and velopharyngeal competence of patients with pharyngeal flaps.

In this study, 129 patients with cleft palate who had pharyngeal flaps were evaluated longitudinally. Articulation scores improved approximately 15 percent following surgery, and by age 16 the majority of subjects achieved velopharyngeal competence and 90 percent correct articulation. The findings also demonstrated that the risk of requiring secondary management increased with the severity of the cleft. In addition, a higher percentage of patients who had received a primary Von Langenbeck procedure required secondary management than did patients who had the Wardill primary palatoplasty. Age at time of the pharyngeal flap operation did not emerge as a critical factor in speech outcome.
