下颌智齿拔除致软组织麻木的临床分析

A clinic analysis on local soft tissue anaesthesia after third mandibular molar extraction

目的分析下颌智齿拔除后局部软组织麻木的临床表现及原因,提出治疗措施。方法回顾性分析8例下颌智齿拔除后发生软组织麻木。结果下颌智齿拔除后发生软组织麻木,以颏区麻木多见(6/8),下唇近中线区(1/8)以及近口角区(1/8)次之。经消炎及神经营养和或物理治疗后8例患者症状逐渐消失。消退时间平均3.9个月,最快为1个月,最慢者达9个月。结论下颌智齿拔除导致的下唇麻木一般为可逆性下牙槽神经损伤,临床治疗可以促进其恢复,但恢复的时间存在差异。

【Objective】 To investigate the clinical manifestation of local soft tissue anaesthesia after the third mandibular molar extraction and to set up a therapy principle. 【Methods】8 cases with local soft tissue anaesthesia after the third mandibular molar extraction were studied. 【Results】In the cases with local soft tissue anaesthesia af-ter the third mandibular molar extraction,6/8 occurred in mental area,and 1/8 occurred near midline and 1/8 near the mouth angle area. The anaesthesia disappeared gradually after treatment with anti-inflammation and neuron-nu-trition and/or physical therapy. The time of disappearance of the anasithesia was between 1 month and 9 months,and the average was 3.9 months. 【Conclusion】The anaesthesia of lower lip by the third mandibular molar extraction is revised due to the alveolar nerve trauma. Clinical therapy can help its recovery,but the duration is different.
