The aim of this study was to analyze several factors regarding their possible influence on neurosensory disturbance (NSD) of the inferior alveolar nerve (IAN) after bilateral sagittal split osteotomy (BSSO).
We investigated the possible influence of sex, age at the time of surgery, total operating time, intraoperative nerve encounter, advancement versus setback, fixation method, additional genioplasty, side, and region (lower lip vs. chin) on subjective neurosensory outcome a half-year after surgery. Results of a battery of neurosensory testing methods are also presented; 103 out of the initial 128 patients were available for further follow-up 1 year after surgery.
Normal subjective sensibility was found in 74.6% and 77.2% of the regions after 6 and 12 months, respectively. Multiple regression models revealed significant effects of age, region, and total operating time after 6 months, and significant effects of age, region, and sex after 12 months.
NSD of the IAN after BSSO is influenced by age, total operating time (at 6 months), and sex (at 12 months). Significantly higher rates of NSD were found in the chin region.
本研究旨在分析多种因素对双侧矢状劈开截骨术（BSSO）后下牙槽神经（IAN）感觉神经损伤（NSD）的可能影响。
我们调查了性别、手术时的年龄、总手术时间、术中神经接触、前徙还是后退、固定方法、颏成形术、手术侧和区域（下唇 vs. 颏部）等因素对术后半年主观神经感觉结果的可能影响。还介绍了一系列神经感觉测试方法的结果；在最初的 128 例患者中，有 103 例在术后 1 年可进行进一步随访。
术后 6 个月和 12 个月时，分别有 74.6%和 77.2%的区域感觉正常。多元回归模型显示，6 个月时年龄、区域和总手术时间有显著影响，12 个月时年龄、区域和性别有显著影响。
BSSO 后 IAN 的 NSD 受年龄、总手术时间（6 个月时）和性别（12 个月时）的影响。颏部区域 NSD 发生率明显较高。
