The purpose of this retrospective study was to determine the patient-reported incidence, duration, and perceived deficit in daily activities associated with lingual nerve (LN) sensory changes after bilateral sagittal split osteotomy (BSSO) of the mandible and to compare them with inferior alveolar nerve (IAN) sensory changes in the same study population.
Questionnaires were mailed to 316 patients who had undergone BSSO procedures between 1980 and 1993. The patients were queried for perceived sensory changes in the distribution of the IAN and LN; duration of these sensory changes; and alteration in daily activities caused by these sensory changes. The same questionnaire was mailed to 47 patients who had undergone isolated genioplasty (GP) to control for the normal variance of non-BSSO surgery on perceived LN sensory changes.
Forty-three percent of the BSSO patients and 38% of the GP patients returned the questionnaires. Within the BSSO group, 19.4% reported LN sensory changes, of which 69.3% reported that these changes resolved within 1 year; 88% reported altered daily activities. By comparison, 95.5% reported a perceived IAN sensory change, of which 27.3% reported that these changes resolved within 1 year; 57% reported altered daily activities. Within the GP control group, 11% reported LN sensory changes; none of the reported sensory changes lasted longer than 1 month.
A small percentage of patients report LN sensory changes after BSSO. When compared with IAN reported sensory changes, LN sensory changes resolve more frequently and sooner, but they are associated with greater perceived deficits in daily activity. The interpretation of the reported incidence of LN change must be critically reviewed because control subjects also responded positively.
本回顾性研究旨在确定患者报告的与下颌骨双侧矢状劈开截骨术（BSSO）后舌神经（LN）感觉变化相关的每日活动中的发生率、持续时间和感知缺陷，并将其与同一研究人群中下牙槽神经（IAN）的感觉变化进行比较。
向1980年至1993年间接受BSSO手术的316名患者邮寄问卷。询问患者IAN和LN分布区域的感觉变化；这些感觉变化的持续时间；以及这些感觉变化引起的日常活动改变。向47名接受单纯颏成形术（GP）的患者邮寄相同问卷，以控制非BSSO手术对LN感觉变化感知的正常差异。
43%的BSSO患者和38%的GP患者回复了问卷。在BSSO组中，19.4%报告有LN感觉变化，其中69.3%报告这些变化在一年内消失；88%报告日常活动有改变。相比之下，95.5%报告有IAN感觉变化，其中27.3%报告这些变化在一年内消失；57%报告日常活动有改变。在GP对照组中，11%报告有LN感觉变化；所有报告的感觉变化持续时间均不超过1个月。
一小部分患者在BSSO后报告有LN感觉变化。与IAN报告的感觉变化相比，LN感觉变化更频繁、更快地消失，但它们与日常活动中更大的感知缺陷相关。由于对照组也有阳性反应，因此必须严格审查报告的LN变化发生率的解释。
