Abstract

Aim The aim of this study was to evaluate the utility and efficacy of bioabsorbable hydroxyapatite and collagen complex for secondary bone graft in unilateral alveolar cleft. Patients and methods From August 2013 to January 2014, 15 patients with unilateral cleft lip and alveolar cleft were enrolled and randomly assigned to two blinded groups. In group I, a cancellous iliac bone graft was placed at the alveolar cleft. In group II, 0.5 ml of HA/Col was placed at the alveolar cleft, and the cancellous iliac bone was positioned in the remaining space. All patients underwent bone grafting with particulate cancellous bone and marrow taken from the anterior iliac crest. Results No complications were observed in any patient. The groups did not differ in age, cleft volume, or surgical duration. Intraoperative blood loss and patient-controlled intravenous analgesia (PCA) use were significantly lower in group II (p <0.05) in comparison to group I. The 1-month volume was 0.895 ml in group I and 0.482 ml in group II (p <0.05). When the 1-month volume in group II was adjusted for 0.5-ml volume of HA/Col, there was no significant difference in the 1-month volumes (p = 0.32). The 6- and 12-month volumes did not differ significantly between the groups (p = 0.768 and p = 0.165, respectively). Conclusion The autogenous bone was gradually absorbed, while the HA/Col was absorbed and replaced by the autogenous bone. Thus, HA/Col can be used as an iliac graft in alveolar bone graft procedures to reduce the amount of autogenous bone required from the crest, patient stress, and morbidity.
