To retrospectively evaluate neurosensory disturbance (NSD) after bilateral sagittal split osteotomy (BSSO).
A retrospective review was carried out to assess inferior alveolar nerve function in patients treated by BSSO from 2010 to 2013. All patients included in the study were assessed using objective (cotton swabs and pin prick testing) and subjective testing (questionnaire) for inferior alveolar nerve function after a minimum of 1 year of follow-up. Medical records of the patients were used to assess the incidence of NSD in the immediate post-operative period.
15 patients (30 sides) had undergone BSSO during the specified time period. On subjective testing, NSD was reported in 22 operated sides (73.3%) in the immediate post-operative period, while 4 operated sides (13.3%) reported persistent NSD. On objective testing, immediate post-operative NSD was seen in 20 operated sides (66.7%). After a minimum of 1 year follow-up, recovery was seen in 18 operated sides while persistent NSD was seen in 2 operated sides (6.7%).
NSD of the inferior alveolar nerve is a common complication after BSSO in the immediate post-operative period. However in a long term, nerve function usually recovers.
回顾性评估双侧矢状劈开截骨术（BSSO）后的神经感觉障碍（NSD）。
对2010年至2013年接受BSSO治疗的患者进行回顾性研究，以评估下牙槽神经功能。纳入研究的所有患者在至少随访1年后，使用客观检查（棉棒和针刺测试）和主观测试（问卷调查）评估下牙槽神经功能。通过患者的病历评估术后即刻NSD的发生率。
在指定时间段内，15例患者（30侧）接受了BSSO。主观测试显示，术后即刻22个手术侧（73.3%）报告有NSD，而4个手术侧（13.3%）报告有持续性NSD。客观测试显示，术后即刻20个手术侧（66.7%）出现NSD。至少随访1年后，18个手术侧恢复，2个手术侧（6.7%）出现持续性NSD。
下牙槽神经的NSD是BSSO术后即刻常见的并发症。然而，从长期来看，神经功能通常会恢复。
