Treatment of alveolar cleft by autogenous cancellous bone graft obtained with mini incision / 实用口腔医学杂志

ABSTRACT

Objective: To sammarize the methodology of the treatment of alveolar cleft by autogenous cancellous bone graft obtained with mini incision(ABGM).Methods: 22 cases of alveolar cleft received ABGM by one operator. The cleft area was restored with autogenous cancellous bone from iliac crest by cylinder osteotomes for extraction of bone transplants(COEBT) with mini incision. All the patients were follow up for at least six months postoperatively. The result of the bone grafting was evaluated on the radiographs. Results: ①The overall survival rate of ABGM was 95.8%,and clinical successful rate was 91.7%;②The successful rate of ABGM in group of patients above 18 year old, or with complete cleft palate or bilateral cleft lip and palate was lower than that in other groups.③The wound for extracting autogenous cancellous bone from iliac crest by COEBT with mini incision was smaller than that by osteotomy. Conclusion: ABGM with COEBT is an effective way in the treatment of alveolar cleft. The successful rate of ABGM is related with the age and cleft style of the patients.
