[A primary clinical analysis of artificial bone implantation of cleft palate].
OBJECTIVE
To observe whether repairing the hard palate can improve velopharyngeal function.


METHODS
40 patients with hard palate cleft were randomly divided into two groups: the control group and the implantation group. Each group had 20 patients. The patients in the implantation group were implanted with compound artificial bone of HA--Bone cement. All patients hag been followed up for three months postoperatively. The patients in the repaired group were examined using computer tomography. All patients were examined using NPF.


RESULTS
The implanted artificial bone had no rejection. The computer tomography showed that the implanted artificial bone in hard palate had no shifting, subsidence or breakage. The movement of soft palate of the implantation group was greater than the control group. The velopharyngeal function of the implantation group was much better than the control group.


CONCLUSIONS
Repairing the hard palate cleft with artificial bone can improve velopharyngeal function.
