PURPOSE
The objective of this study was to clinically evaluate the frequency, type, and risk factors for lingual nerve damage after mandibular third molar surgery with reference to lingual flap retraction.
PATIENTS AND METHODS
A total of fifty-five patients referred for bilateral mandibular third molar removal were included in this study. Each patient was randomly allotted to have the procedure performed on 1 side (experimental group) with lingual flap retraction. On the opposite side (control group), the same procedure was performed without lingual flap retraction.
RESULTS
Lingual nerve damage occurred in 9.1% in the experimental group in which lingual flap retraction was performed. In the control group, damage to the lingual nerve was not observed. The difference was statistically significant (P <.001) as measured by the Cochran test.
CONCLUSION
Lingual nerve retraction represented a risk factor to temporary lingual nerve damage during mandibular third molar surgery.
目的
本研究的目的是参照舌侧瓣牵拉情况，对下颌第三磨牙手术后舌神经损伤的频率、类型和危险因素进行临床评估。
患者与方法
本研究纳入了55例因双侧下颌第三磨牙拔除前来就诊的患者。每位患者被随机分配在一侧（实验组）进行伴有舌侧瓣牵拉的手术。在对侧（对照组），进行相同手术但不进行舌侧瓣牵拉。
结果
在进行舌侧瓣牵拉的实验组中，舌神经损伤发生率为9.1%。在对照组中，未观察到舌神经损伤。通过 Cochr an检验测量，差异具有统计学意义（P <.001）。
结论
舌神经牵拉是下颌第三磨牙手术期间导致舌神经暂时性损伤的一个危险因素。
