腭侧入路牙槽突裂植骨术的初步应用与评价

Initial study and evaluation on alveolar bone graft by palate side approach

目的改进牙槽突裂植骨术的技术方法,并对腭侧入路牙槽突裂植骨术的即刻效果进行初步评价。方法选取20名非综合征性单侧牙槽突裂患者为研究对象,其中不完全性牙槽突裂患者8名,完全性牙槽突裂患者12名。对20例患者实施腭侧入路牙槽突裂植骨术,在术前和术后分别拍摄锥形束CT(CBCT)片,使用Image-Pro Plus 5.1软件测量相关数据并进行统计学分析。结果 20名患者中总体植入骨量比率为88%,唇侧植入骨量比率为93%,腭侧植入骨量比率为84%。结论腭侧入路牙槽突裂植骨术弥补了既往腭侧植入骨量不足的缺点,裂隙内鼻腔瓣三角瓣的切口设计兼顾了鼻底裂隙和唇侧裂隙的关闭,避免大范围的松弛切口以及颊侧黏膜推进瓣的应用。

Objective To observe and improve the short-term outcome of alveolar bone graft CABG） by palate side approach. Methods ABG by palate side approach was performed in twenty patients with non-syndromic unilateral complete cleft lip and palate. Eight patients were incomplete cleft alveolar, and twelve patients were complete cleft alveolar. Each patient took cone beam computer tomography （CBCT） before and after surgery. The related data was measured by Image-Pro Plus 5.1 and analyz statistically. Results The overall implanted bone mass ratio was 88%, the labially implanted bone mass ratio was 93%, and the palately implanted bone mass ratio was 84%. Conclusion ABG solve the shortcoming of bone insufficient at palatal side. Triangle nasal flap in cranny can assume the closure of nasal floor and palatal mucosa, avoid a large range of relaxation incision and applying of buceal mucosal advancement flap.
