摘　　要：目的 :研究确定咽旁颞下区重要结构的体表标志及对临床的指导作用。方法 :解剖新鲜尸头 6具 ,观测 12例咽旁颞下区的体表解剖标志及文献复习。结果 :骨性外耳道下内 ( 11.5± 2 .0 )mm为颈内静脉孔外壁 ,髁状突内缘距颈内动脉管外口为 ( 10 .0± 1.3 )mm ,下颌角后缘 ( 12 .0± 3 .0 )mm有颈内动脉经过 ,第一颈椎横突前 ( 5 .0± 2 .0 )mm为颈内静脉后壁。结论 :以骨性外耳道下点为A ,髁状突前点为B ,下颌角点为C ,第一颈椎横突点为D ,组成的四边形为咽旁颞下区后部重要结构的体表标志。BC线可作为咽旁颞下区前、后部的分界线。此标志对该区病变的诊断。Objective: To study surface landmark of the blood vessles i n subtemporal parapharyngeal region. Methods:6 corpse heads were dissected, the anatomical character and the ralationship between surface landma rks and blood vessels was observed. Results:The distance between inferior medial point of meatus acusticus externus and internal jugular vein fo ramen was (11.5±2.0) mm, that between medial margin of condyle process and in ternal artery foramen was (10.0±1.3) mm. Internal carotid artery was (12.0± 3.0) mm away from posterior margin of mandibular horn, internal jugular vein wa s (5.0±2.0) mm in front of the transverse process of the first cervical verte brae (S1).Conclusions:The inferior point of meatus acustics exte rnus, anterior point of condyle process, mandibular horn and transverse process of S1 can be used as surface landmarks for internol jugular vein and carotid art ery.
