OBJECTIVE
This prospective study reports the proportion of permanent sensory impairment of the inferior alveolar and lingual nerves and the factors influencing such prevalence after the removal of mandibular third molars under local anesthesia.
STUDY DESIGN
There were 1,087 patients with 1,087 mandibular third molars removed under local anesthesia from 1998 to 2003. Standardized data collection included the patient's name, age, gender, radiographic position of extracted tooth, grade of surgeon, proximity of the inferior alveolar nerve, and the prevalence of lingual and/or inferior alveolar nerve paresthesia.
RESULTS
Inferior alveolar nerve injury was 4.1% 1 week after surgery and decreased to 0.7% after 2 years of follow-up, and alteration in tongue sensation occurred in 6.5% of patients 1 week after surgery and decreased to 1.0% after 2 years of follow-up.
CONCLUSION
The experience of the operator was found to be a significant factor in determining both permanent lingual nerve (P=.022) and permanent inferior alveolar nerve paresthesia (P=.026).
目的
本前瞻性研究报告了在局部麻醉下拔除下颌第三磨牙后下牙槽神经和舌神经永久性感觉障碍的比例以及影响该发生率的因素。
研究设计
1998年至2003年期间，对1087例在局部麻醉下拔除1087颗下颌第三磨牙的患者进行研究。标准化数据收集包括患者姓名、年龄、性别、拔牙的影像学位置、外科医生级别、下牙槽神经的接近程度以及舌神经和/或下牙槽神经感觉异常的发生率。
结果
术后1周下牙槽神经损伤率为4.1%，随访2年后降至0.7%；术后1周6.5%的患者出现舌感觉改变，随访2年后降至1.0%。
结论
研究发现，术者经验是决定舌神经永久性感觉异常（P = 0.022）和下牙槽神经永久性感觉异常（P = 0.026）的重要因素。
