唇、腭侧联合入路修复牙槽突裂的临床初步研究

目的：探讨唇、腭侧联合入路修复牙槽突裂的临床效果。方法45例先天性牙槽突裂患者接受植骨手术修复，其中21例（年龄9~13岁，平均年龄10.3岁）行唇、腭侧联合入路植骨修复（实验组），24例（年龄9~14岁，平均年龄11.2岁）行唇侧入路植骨修复（对照组）。术后1~12个月随访，采用临床回顾性研究的方法比较2组术后疼痛、肿胀程度；牙槽突裂植骨成功率评价的临床分级标准一般以Bergland牙槽突裂植骨分级标准进行评价。结果实验组在术后疼痛、肿胀程度均低于对照组；实验组植骨手术成功率81%，对照组植骨手术成功率42%。结论唇、腭侧联合入路植骨修复牙槽突裂手术创伤小、术后不良反应少，临床效果满意。

Clinical study on secondary alveolar bone grafting by lip side combined with palate side approach

Objective To assess the clinical effect of secondary alveolar bone grafting(SABG) by lip side combined with palate side approach. Methods The study included 45 cases of alveolar clefts treated with SABG. The experimental group comprised 21 alveolar cleft cases that received SABG by lip side combined with palate side approach(age range 9-13 years, mean age 10.3 years). The control group comprised 24 alveolar cleft cases that received SABG by lip side approach(age range 9-14 years, mean age 11.2 years). Postoperative pain and swelling were recorded and analyzed. After a follow-up period of 1-12 months, the amount of bone in the SABG areas were retrospectively analyzed according to the Bergland scales. Results The occurrence of postoperative pain and swelling in the experimental group was lower than that in control group. A total of 81%of cases in the experimental group were categorized as successful, and 42%of cases in the control group were categorized as successful. Conclusion SABG through lip side combined with palate side approach has a high success rate with a low incidence of complications. This method has satisfactory clinical results with less surgical trauma and postoperative adverse reactions.
