Abstract: Objective　To study the bone healing situation of the cleft palate after surgical procedure，and disccuss the factors affecting it. Methods　20 patients with repaired cleft palate were examined by CT scan coronally. The result of images were observed and the position, shape and quality of bone bridge were measured. Results　Formation of bone bridge was found in 13 cleft gaps out of 20 patients (65%),the sex ratio among patients with bone bridge was 1∶1; there was no obvious difference between unilateral and bilateral cleft palate. Considering the operation age with the bone formation ,the highest percentage of bone bridge formation fell into the group of 4～6 years old, and the most occuring regions were in premolar and anterior part of molar area. Conclusions　There can be new bone bridge regeneration in bone gap after palate surgery,and the bone formation may have some relationship with the operation age and surgical technique.
