OBJECTIVE: To observe whether repairing the @entity2419 can improve velopharyngeal function. METHODS: 40 @entity1 with hard @entity2419 were randomly divided into two groups: the control group and the implantation group. Each group had 20 @entity1 . The @entity1 in the implantation group were implanted with compound artificial bone of HA--Bone cement. All @entity1 hag been followed up for three months postoperatively. The @entity1 in the repaired group were examined using computer tomography. All @entity1 were examined using NPF. RESULTS: The implanted artificial bone had no rejection. The computer tomography showed that the implanted artificial bone in @entity2419 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. CONCLUSION: Repairing the hard @entity2419 with artificial bone can improve velopharyngeal function.
