| Outline of Final Research Achievements |
To establish the system of objectively evaluation for velopharnyngeal function before and maxillary advancement surgery in patient with cleft lip and palate, we objectively evaluated these parameters in patients with velopharyngeal insufficiency following palatoplasty due to cleft palate.The subjects were 10 cleft palate patients who underwent Le-Fort I osteotomies .A nasameter test was performed using a nasometer. The articulation during speech was evaluated by a speech therapist. These evaluations were performed immediately before surgery and 2-3 weeks, 3 months, and 6 months after surgery. The nasalance score was found to temporarily worsen after surgery, but recovered within 6 months. Abnormal articulations were detected in two atients, but this similarly recovered within 6 months. Based on these findings, surgical maxillary advancement could be a useful strategy for patients with velopharyngeal insufficiency following palatoplasty due to cleft palate.
