[A comparative study on the nasolance and graph pattern of cleft palate patients before and after operation]

The aim of the present study is to compare the nasolance score and graphic pattern of the nasometric registration before and after cleft palate repair. Sixty cleft palate patients were studied with nasometer. One month after operation the nasolance is significantly lower as compared with the preoperation sequence and the number of "up and down" pattern has increased significantly. These results indicate that the velopharygeal function starts to recover one month after operation and the speech training can be given at the mean time. The speech results should be assessed at least three months after operation.
