ABSTRACT
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.
