Since cleft alveolar bone grafting is more difficult, and especially in the operation, nasal floors, oral vestibules and mucous membrane and periosteum valves in palates should be completely closed, the pivotal points are sufficient loosing of periosteum valves and non-strain suture.

牙槽峭裂植骨手术难度较大，尤其要彻底封闭鼻底、口腔前庭和胯部的粘骨膜瓣，因此在术中充分松解粘骨膜瓣，无张力缝合伤口是手术成功的关键。
