Abstract:
OBJECTIVEAttending to observe the bony healing on hard palate after palatal repair, and to discuss the factors affecting on it.
METHODS52 patients with repaired cleft palate over 5 years postoperatively were examined, the CT scan of head was taken. The incidence of the bone regeneration among the patients examined was calculated, the position and quality of bone tissue were measured according to the CT images. After all, analysis was applied to evaluate the factors affecting on the bone tissue formation.
RESULTSFormation of bone bridge was found in the 37 cleft gaps out of 52 patients (71%), the ratio of the sex among the patients who had 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 4-7 years old, and the most occurring region were in premolar and anterior part of molar area.
CONCLUSIONThere could be bony healing(regeneration bone tissue RBT) after palatal repair on cleft palate patients. The operation age could be an important affecting factor to RBT, but the sex and the clinical type of cleft palate make no difference on the bone tissue formation.
