Palatal length in cleft palate as a predictor of speech outcome.

In an attempt to predict which patients might benefit from primary posterior pharyngeal flaps done at the time of palatal repair, palatal length was assessed before palatal repair and the patient was placed in one of four categories. Patients with longer palates preoperatively had statistically better speech outcomes than patients with shorter palates. Statistical significance was found for most speech parameters. Information on presurgical palatal length can be useful in predicting which patients might profit from primary "pharyngoplasties."
