This literature review assessed the risk factors linked to inferior dental nerve (IDN) and lingual nerve (LN) deficits following lower wisdom tooth surgery. A computer search of several databases with specified key words was performed. 32 articles were selected; the risk factors for IDN deficit were reported in 4 articles, LN in 9 and both IDN and LN in 19. Data were analysed statistically to evaluate the potential risk factors. Literature review showed specific radiographic signs and intra-operative IDN exposure increased the risk of IDN deficit. Raising the lingual flap significantly increased the risk of LN deficit. Unerupted tooth and lingual split technique increased IDN and LN deficit risks significantly. Age was linked to IDN and LN deficits, and deep impaction was related to IDN deficit, but no statistical tests were performed on these two risk factors owing to the heterogeneity of data from the studies. This literature review found increased age, unerupted tooth, deep impaction, specific radiographic signs, intra-operative IDN exposure and lingual split technique were risk factors for IDN deficit; increased age, unerupted tooth, distal impaction, raising of lingual flap and lingual split technique were risks factors for LN deficit in lower wisdom tooth surgery.
这篇文献综述评估了在下颌智齿手术中与下齿槽神经（IDN）和舌神经（LN）缺损相关的风险因素。通过特定关键词对几个数据库进行了计算机检索。选择了 32 篇文章；有 4 篇文章报道了 IDN 缺损的风险因素，9 篇报道了 LN 缺损的风险因素，19 篇报道了 IDN 和 LN 两者的风险因素。对数据进行了统计学分析，以评估潜在的风险因素。文献综述表明，特定的影像学征象和术中 IDN 暴露增加了 IDN 缺损的风险。升高舌瓣显著增加了 LN 缺损的风险。未萌出的牙齿和舌侧劈开技术显著增加了 IDN 和 LN 缺损的风险。年龄与 IDN 和 LN 缺损有关，深埋伏与 IDN 缺损有关，但由于研究数据的异质性，对这两个风险因素未进行统计学检验。本文献综述发现，年龄增加、未萌出的牙齿、深埋伏、特定的影像学征象、术中 IDN 暴露和舌侧劈开技术是 IDN 缺损的风险因素；年龄增加、未萌出的牙齿、远中埋伏、升高舌瓣和舌侧劈开技术是下颌智齿手术中 LN 缺损的风险因素。
