成年人下颌隆突解剖学观测及临床意义

Anatomical observation and clinical significance of human mandibular protuberance

目的观测成年人下颌隆突形态结构及其与周围结构的关系,为下颌隆突阻滞麻醉术的定位提供客观参数。方法使用游标卡尺(精确度为0.1mm)圆规和直尺对92例(184侧)下颌骨下颌隆突相关解剖学标志进行形态学观测,记录数据并进行统计学分析。结果下颌隆突形态不规则,在下颌小舌上点处,下颌隆突的水平宽度为(8.67±1.65)mm,下颌神经沟的宽度为(12.44±1.81)mm。下颌隆突的垂直高度为(17.86±3.49)mm,下颌小舌的垂直高度为(9.63±2.23)mm。结论本研究结果为临床下颌隆突阻滞麻醉的定位提供理论依据。

Objective To observe the morphological structure of mandibular protuberance and its relationship with surrounding structures in adults, and to provide objective parameters for block anesthesia of mandibular protuberance. Methods The vernier caliper and compasses and ruler were used to determine the morphological structure of mandibular and related anatomical landmarks in 92 cases（184 sides） of the mandible, the results were recorded and analyzed statistically. Results The mandibular protuberance was irregular in shape, and the horizontal width of the mandibular protuberance was（8.67 ±1.65）mm and the width of the mandibular nerve ditch was（12.44 ±1 1.81）mm at the level of mandibular lingula. The vertical height of the mandibular protuberance is（17.86 ±13.49）mm, and the vertical height of the mandibular lingula is（9.63 ±1 2.23）mm. Conclusion The present results would provide a theoretical basis for the location of mandibular protuberance block anesthesia in clinic.
