目标.计算下牙槽神经（IAN）损伤的发生率，由于下第三磨牙拔除，并描述IAN敏感性的演变和IAN损伤的预后基于术前数据。研究设计。对3513例门诊患者中4995例拔除下颌第三磨牙的病例进行回顾性研究。55例拔牙（1.1%）导致IAN受损。考克斯回归分析显示年龄是下颌第三磨牙拔除导致IAN损伤持续存在的危险因素。感觉恢复率在前3个月较高。50%的患者在6个月后完全康复。大多数病例在拔除下颌第三磨牙后的IAN损伤在6个月内恢复，尽管在某些病例中恢复需要1年以上。老年患者在拔除第三磨牙后下巴和嘴唇感觉不完全恢复的风险增加。
Objectives. To calculate the incidence of inferior alveolar nerve (IAN) damage due to lower third molar extraction and to describe the evolution of IAN sensitivity and the prognosis of IAN damage based on preoperative data.Study design. A retrospective study of 4995 lower third molar extractions in 3513 outpatients.Results. Fifty-five extractions (1.1%) resulted in IAN impairment. Cox regression analysis showed age to be a risk factor for the persistence of IAN injury due to lower third molar extraction. The sensation recovery rate was higher in the first 3 months. Fifty percent of the patients showed full recovery after 6 months.Conclusions. Most cases of IAN impairment following lower third molar extraction recover within 6 months, though in some cases recovery takes more than I year. Older patients are at an increased risk of incomplete recovery of chin and lip sensibility after third molar extraction.
