| Research Abstract |
1) Assessment of preoperative condition of cleft palate : preoperative condition of cleft palate was assessed by intrraoral finding, lateral cephaligram and Echogram of the movement of lateral pharuyugeal wall. We can ralate the velopharyngeal function * iVPF *j with the musclar condition of the soft palate, and the movement of lateral pharyngeal wall with the function of the soft palate. We cannont find the difference of VPF between the isolated cleft palate and the clefi lip and palate.
2) The process of the attainning of VPF after palate rrepair. A Widmaier method *F Assessment of the VPF after operation with 35 patients was done by intra oral finding, videofluorography, nasopharyngel fiber scope, and echogram. The function was attained at the vowel pronunciation in the 2 years after operation (3 years old). Whereas the function at the consonant pronunciation and blowing was attained about 5 years old. And the function was related to not only the function of the soft palate, but also

the lateral wall movement.
B Furlow's method *F We assessed the VPF of the patients (20 cleft palate, 8 submucous cleft palate, 3 cleft lip and palate) by the same method in A.The function was attained in the 2years after operation (about 3 years old) at almost all the functions. and it was related to the nallowing of velopharyngeal area after operation.
Secondary plaratal repair by Furlow's method has been done in the patients with velopharyngeal insufficiency after primary repair. In 16 cases after operation, we find the increasing of the mobility of the soft palate and lateral pharyngeal wall in 2-3 montths after operation. And in almost all cases, normal function was attained after 6 months.
C push back method *F We cannot assessed the function after operation because the case was few and they are complicated with mental retardation or other anomalies related to the speech problem.
3) Assessment of the speech ; Speech results were assessed about the patients at the 4-6 years old. In the cases after Widmaier palatal repair, normal speech was attained at 4-5years old, however in the cases after Furlow's platal repair normal speech was attained 3-4 years old. Less
