Management of alveolar cleft has dramatically changed during the last century: secondary alveolar bone grafting is now an integral part of cleft palate and craniofacial center's protocols. The objectives of alveolar repair and bone grafting are as follows: providing a continuous and stable maxillary dental arch, closure of oronasal fistulae, adequate bone for tooth eruption or orthodontic movement, and nasal base support, improving facial aesthetic. Although cancellous iliac bone is the donor site selected more frequently, bone grafts harvested from different sites have been advocated to decrease donor site morbidity.The aim of this study was to propose and evaluate the use of olecranon as a donor site in 24 patients with secondary alveolar cleft. The graft is taken as a single piece to fit the alveolar cleft defect, and it includes periosteum and corticocancellous bone to improve early vascularization and greater volume maintenance.
在上个世纪，牙槽嵴裂的治疗发生了巨大变化：二期牙槽骨移植如今已成为腭裂和颅面中心治疗方案中不可或缺的一部分。牙槽嵴修复和骨移植的目标如下：提供连续且稳定的上颌牙弓，关闭口鼻瘘，为牙齿萌出或正畸移动提供足够的骨量，以及鼻基底支撑，改善面部美观。尽管松质髂骨是最常选用的供骨部位，但也有人主张采用从不同部位获取的骨移植来降低供骨部位的并发症。本研究的目的是提出并评估将尺骨鹰嘴作为24例二期牙槽嵴裂患者的供骨部位。移植骨作为单块取下以适配牙槽嵴裂缺损，并且它包括骨膜和皮质松质骨，以改善早期血管化并维持更大的骨量。
