Bone Regeneration on the Hard Palate after Palatal Repair on Cleft Palate Patients: A Preliminary Observation

Ningbei Yin/Lian Ma/Zhenkang Zhang/Tong Zhu

Objective: To observe bony healing on the hard palate after cleft palate repair and to discuss the relative factors. Methods: Twenty patients with repaired cleft palates were examined postoperatively over 5 years. A CT scan of the head was taken. The incidence of bone regeneration among the patients examined was calculated; the position and length of bone tissue were measured according to the CT images. Results: Formation of bone tissue was found in 13 out of the 20 patients (65%). The sex ratio among the patients was 1:1. There was no obvious difference between cleft types (unilateral:bilateral = 1:1). Regarding operation the age of the patients, the highest incidence of bone formation was in the group of 4-6-year-olds, and most showed improvement in the premolar and anterior molar areas. Conclusions: There can be bony healing (regeneration of bone tissue GBT) after palate repair in cleft palate patients.
