PURPOSE
The present retrospective cohort study compared the subjective inferior alveolar nerve (IAN) function after distraction osteogenesis (DOG) and bilateral sagittal split osteotomy (BSSO) in mandibular advancement surgery.
MATERIALS AND METHODS
Treatment consisted of correction of a retrognathic mandible using DOG (30 patients) or BSSO (35 patients). Subjective IAN function was recorded using a questionnaire 1 year after surgery. A total of 130 IANs were evaluated.
RESULTS
In 37 nerves (28.5%), an IAN disturbance was observed. In this group of 37 nerves, BSSO had been performed in 26 (70.3%) and DOG in 11 (29.7%). After eliminating confounders (eg, age, amount of advancement, gender), no significant difference (odds ratio 0.652, 95% confidence interval 0.221 to 1.920) was found. Age was significantly related to subjective IAN disturbances for women but not for men. This was seen in women older than 22 years and increased for women older than 36 years to an odds ratio of 22.8 (95% confidence interval 2.580 to 201.488). Satisfaction also correlated with age, independent of gender.
CONCLUSION
No difference was found in subjective IAN disturbances after 1 year between DOG and BSSO for lengthening the mandible.
目的
本回顾性队列研究比较了下颌前徙手术中牵张成骨术（DOG）和双侧矢状劈开截骨术（BSSO）后下牙槽神经（IAN）的主观功能。
材料与方法
治疗包括使用DOG（30例患者）或BSSO（35例患者）矫正下颌后缩。术后1年使用问卷记录IAN的主观功能。共评估了130条IAN。
结果
在37条神经（28.5%）中观察到IAN功能障碍。在这37条神经中，26条（70.3%）接受了BSSO，11条（29.7%）接受了DOG。在消除混杂因素（如年龄、前徙量、性别）后，未发现显著差异（优势比0.652，95%置信区间0.221至1.920）。年龄与女性IAN主观功能障碍显著相关，而与男性无关。在22岁以上的女性中可见这种情况，36岁以上女性的优势比增加至22.8（95%置信区间2.580至201.488）。满意度也与年龄相关，与性别无关。
结论
DOG和BSSO在下颌延长术后1年IAN主观功能障碍方面无差异。
