This study was carried out in order to evaluate musculoskeletal adaption to surgical advancement of the deficient mandible. 10 adult individuals with mandibular deficiency were studied before and 3 months after surgical advancement of the mandible via lateral cephalometric radiography, kinesiometry, and electromyographic instrumentation. 10 adult controls were studied at the same intervals, but underwent no surgery. The data was entered into a DEC System-10 computer for morphometric comparison and statistical analysis. The results of this investigation demonstrate that musculoskeletal adaptions occur within the stomatognathic system following surgical advancement of the mandible. 3 months following surgery, the clinical and physiological rest positions of the mandible as well as the masticatory electromyographic activity were unchanged in both the control and the surgery groups. The rapid, functional adaptions that occurred in the surgery group are apparently due to changes in posterior ramus-mandibular body relations and neuromuscular adaption within the masticatory and suprahyoid musculature.
本研究旨在评估肌肉骨骼系统对下颌骨发育不全手术前移的适应性。通过头颅侧位X线摄影、运动测量法和肌电图检测手段，对10例下颌骨发育不全的成年个体在进行下颌骨手术前移之前及术后3个月进行了研究。10名成年对照者在相同的时间间隔接受研究，但未接受手术。数据被录入DEC System-10计算机进行形态计量学比较和统计分析。本研究结果表明，下颌骨手术前移后，口颌系统内会发生肌肉骨骼适应性变化。术后3个月，对照组和手术组的下颌骨临床和生理休息位以及咀嚼肌肌电活动均未改变。手术组中发生的快速功能适应性变化显然是由于下颌支后缘与下颌体关系的改变以及咀嚼肌和舌骨上肌群内的神经肌肉适应性变化所致。
