Purpose:
The purpose of the present review was to evaluate the protocol and technique used in a large population of patients with cleft lip and palate when secondary grafting is performed during the early mixed dentition stage, as determined by eruption of the central incisor. In the United States, most investigators have recommended alveolar grafting at the 9- to 11-year age range or before eruption of the permanent canines.
Materials And Methods:
An institutional review board-approved chart review of 99 patients undergoing alveolar cleft bone grafting during a 7-year period at a single institution was performed. Data were collected regarding demographics, operative time, length of hospitalization, follow-up time, complications, and additional procedures performed. The cases were divided by patient age into 2 groups: group 1, aged 6 to 8 years (n = 61); and group 2, aged 9 years and older (n = 38). Statistical analysis was performed for various comparisons in the study.
Results:
The average operative time for groups 1 and 2 was 86 and 103 minutes, respectively. The complication rate, length of stay, and follow-up time between the 2 groups was not statistically significant at the P = .05 significance level.
Conclusions:
We recommend earlier bone grafting at or before the eruption of the central incisor, rather than delaying until the cuspid tooth root is 25% formed. We believe this will provide better bone support for the dentition, a decreased burden of treatment for the patient, and improved quality of life. Performing the procedure at this time can lead to decreased operative times, with comparable postoperative outcomes.
