STUDY DESIGN
A cross-sectional study.
OBJECTIVE
Neurosensory disturbances (NSDs) of the infraorbital nerve (ION) are common following orbito-zygomaticomaxillary complex (ZMC) fractures. This study aimed to evaluate the effect of lag time between injury and treatment on recovery of NSDs of the ION following open reduction internal fixation.
METHODS
Subjects who had ZMC fracture and paresthesia were studied. The lag time between injury and treatment was considered as the predictive factor. The level of NSDs according to the brush test and two-point discrimination (TPD) test and self-reported NSD were the outcomes of this study. Self-reported NSD was quantified using a visual analog scale.
RESULTS
Forty patients were studied. The lag time between injury and treatment had a significant correlation with the result of the TPD test and the self-reported level of NSD. In 73.6% of patients who had NSD following ZMC fracture, every 1-day delay in treatment increased the incidence of self-reported paresthesia by 0.44.
CONCLUSIONS
It seems, a delay in treatment of ZMC fractures increased the risk of NSD.
研究设计
横断面研究。
目的
眶颧上颌复合体（ZMC）骨折后，眶下神经（ION）的神经感觉障碍（NSDs）很常见。本研究旨在评估损伤与治疗之间的延迟时间对切开复位内固定术后ION的NSDs恢复的影响。
方法
对患有ZMC骨折和感觉异常的受试者进行研究。损伤与治疗之间的延迟时间被视为预测因素。本研究的结果是根据刷试和两点辨别（TPD）测试得出的NSDs水平以及自我报告的NSD。自我报告的NSD使用视觉模拟量表进行量化。
结果
对40名患者进行了研究。损伤与治疗之间的延迟时间与TPD测试结果和自我报告的NSD水平显著相关。在ZMC骨折后患有NSD的患者中，73.6%的患者每延迟1天治疗，自我报告的感觉异常发生率就增加0.44。
结论
似乎，ZMC骨折治疗的延迟会增加NSD的风险。
