Subjects were 51 patients undergoing folded pharyngeal flap surgery for velopharyngeal incompetence at the Department of Otolaryngology of Kagawa Medical University between August 1985 and July 2001.<br>Causal diseases were cleft palate in 27 (53%), submucous cleft palate in 8 (16%), and congenital velopharyngeal incompetence in 16 (31%). In history, 31% with congenital velopharyngeal incompetence, 25% with submucous cleft palate, and 11%, with cleft palate had congenital abnormalities. In addition, 56% with congenital velopharyngeal incompetence, 38%, with submucous cleft palate, and 15% with cleft palate had mental retardation, indicating that it occurred with high frequency in patients with congenital velopharyngeal incompetence.<br>The postoperative improvement of nasality was investigated in 48 patients whose progress could be observed for more than 1 year. Of 39 preoperatively diagnosed with advanced velopharyngeal dysfunction, 34 (87%) showed improved nasality. Of 9 with preoperatively slight deficiency, 8 (89%) improved nasality. The blowing test showed no difference in results between patients who had advanced and slight deficiency. Articulation on speech level improved to be normal in 78% of patients with slight deficiency, but only in 46% of those with advanced deficiency. Improvement of articulation on a speech level was high (86%) in patients with submucous cleft palate, but low in patients with congenital velopharyngeal incompetenec who had mental retardation. Further study is required to detail postoperative prognosis factors.
