A prospective study was carried out on the effects of surgical, operator, and anatomical variables on the incidence and duration of lingual dysaesthesia after the surgical removal of impacted lower third molars under general anaesthesia. The predictive value of the area of sensory loss in relation to recovery was also studied. 120 instances of dysaesthesia occurred following 1040 operations in 602 patients, an overall incidence of 11.5%. The effects of 22 possible causative factors, analysed initially by the X2 test, are recorded. Since factors may not be independent, the results were then subjected to logit analysis, revealing highly significant effects from depth of impaction, removal of overhanging distal bone, lingual flap elevation, and operating time. Neither individual operators nor operator seniority had significant effects on the incidence. 6 cases of dysaesthesia failed to recover within 6 months. Where the area of sensory loss was incomplete, recovery occurred within 6 months in all cases.
一项前瞻性研究针对全身麻醉下拔除下颌阻生第三磨牙术后，手术、术者及解剖学变量对舌感觉异常的发生率及持续时间的影响展开。同时还研究了感觉丧失区域与恢复情况相关的预测价值。602例患者接受了1040次手术，其中发生120例感觉异常，总发生率为11.5%。记录了最初通过X²检验分析的22种可能致病因素的影响。由于各因素可能并非相互独立，随后对结果进行了logit分析，结果显示阻生深度、去除远中悬突骨、舌侧瓣掀起及手术时间有高度显著影响。个体术者及术者年资对发生率均无显著影响。6例感觉异常在6个月内未恢复。感觉丧失区域不完全的所有病例均在6个月内恢复。
