BACKGROUND: Alveolar bone grafting is an important component of cleft lip and palate treatment, with iliac crest as the most common donor site. Although studies have attempted to quantify alveolar bone graft resorption, few have directly compared the outcomes of graft techniques. This study compared the long-term success rates of corticocancellous block to trephine cancellous-only alveolar bone grafting from the iliac crest.
METHODS: A retrospective review of all cleft lip and palate patients undergoing alveolar bone grafting over 14 years was performed. Power analysis was performed to determine sample size. Data including patient demographics, surgical technique, need for repeated grafting, complications, length of hospitalization, and follow-up were collected. Statistical analyses of outcomes were performed based on initial graft technique.
RESULTS: A total of 106 initial operations met criteria, with 73 using trephine technique, 30 using corticocancellous block, and three undergoing open cancellous harvest. The overall regraft rate was 40 percent, with an average follow-up of 43.5 months. Patients with corticocancellous block grafting had significantly lower rates of repeated grafting compared to trephine technique (16.7 percent versus 47.9 percent; p < 0.001). There was no significant difference in complication rates or length of admission between treatment groups.
CONCLUSIONS: The use of corticocancellous block alveolar bone grafting demonstrated significantly higher success rates when compared to cancellous-only trephine techniques, with no difference in complication rates. Although this must be weighed against the minor disadvantages of open iliac harvest, surgeons should consider incorporating en bloc corticocancellous bone to optimize outcomes in alveolar bone grafting.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
