UNLABELLED
Mandibular skeletal deformities are mostly corrected by Sagittal Split Ramus Osteotomy. One of the main complications of Bilateral Sagittal Split Ramus Osteotomy is impairement of sensory function of Inferior Alveolar Nerve.
OBJECTIVES
To evaluate the occurrence of neurosensory disturbance by comparing the subjective and objective assessment of neurosensory responses after bilateral sagittal split ramus osteotomy.To assess the progress of recovery from the first post operative day till six months. To explain the factors causing neurosensory disturbances.
METHOD
A series of 24 patients with clinically and radiographically diagnosed mandibular skeletal deformity were treated with Bilateral Sagittal Split Ramus Osteotomy. For evaluation of the neurosensory responses, the parameters consist of subjective and objective test in order to compare the subjective and objective assessment.
RESULTS
On the first post operative day neurosensory disturbances were seen in all the patients. Recovery of sensation was seen in all the patients at the end of this study.
CONCLUSION
The incidence of functional nerve disturbances is acceptable, since the progression towards recovery is inevitable. Prolonged neurosensory disturbance is greatly related to the degree of manipulation of the inferior alveolar nerve.
未标注
下颌骨骨骼畸形大多通过下颌升支矢状劈开截骨术进行矫正。双侧下颌升支矢状劈开截骨术的主要并发症之一是下牙槽神经感觉功能受损。
目的
通过比较双侧下颌升支矢状劈开截骨术后神经感觉反应的主观和客观评估，评估神经感觉障碍的发生率。评估从术后第一天到六个月的恢复进程。解释导致神经感觉障碍的因素。
方法
对一系列24例经临床和影像学诊断为下颌骨骨骼畸形的患者进行双侧下颌升支矢状劈开截骨术治疗。为评估神经感觉反应，参数包括主观和客观测试，以便比较主观和客观评估。
结果
术后第一天所有患者均出现神经感觉障碍。在本研究结束时，所有患者的感觉均恢复。
结论
功能性神经障碍的发生率是可以接受的，因为恢复进程是不可避免的。长时间的神经感觉障碍与下牙槽神经的操作程度密切相关。
