The congenital defects of cleft lip and palate are the most common facial deformity. This deformity usually was combined with alveolar cleft. The lack of alveolar continuity, it can affect maxillary growth, eruption of permanent teeth, and results in feeding problems or speech disorders. Autogenous bone grafts have been used to restore alveolar continuity, which is an extremely important to reconstruct the integrity of maxilla. Here we report a case of bilateral cleft lip and palate. She had received surgical repair for cleft lip and palate at her childhood. But she had not sought autogenous bone grafting for alveolar cleft. We harvested the proximal tibia bone grafts to repair the alveolar cleft. The procedure for proximal tibia bone graft is easy, has less operative risk, and result in a lower postoperative morbidity rate.
