[A retrospective analysis of autogenous alveolar bone grafting in clefts of the lip and palate].

OBJECTIVE

To analyse factors which are able to influence the result of alveolar bone grafting (AABG).

METHODS

A retrospective analysis was performed in a group of 54 alveolar cleft patients (30 males and 13 females, total 66 sides) who received AABG. The age range of the patients was 8-44 years. The cleft area was restored with autogenous cancerous bone from iliac crest. All the patients have been followed up for at least three months postoperatively. The result of the bone grafting was evaluated on the radoigraphs.

RESULTS

1. The overall survival rate of AABG was 94%, and clinical successful rate of AABG was 89%; 2. The successful rate of AABG was correlated with the age of the patients. The successful rate of AABG in group of patients above 18-year-old was significantly lower than other groups; 3. With the exception of cleft palate fistula operation, when the AABG was done simulatneously with other cleft lip and palate operations, the successful rate of AABG was not significantly different from that of the sole AABG operation; 4. The successful rate of AABG in patients with cleft lip or incomplete cleft palate was superior to patients with complete cleft palate.

CONCLUSION

Forming of excelent bone grafting bed and closely surturing is the key to the success of AABG.
