Because the main trunks of the external carotid artery and maxillary artery are well protected from blunt trauma and superficial penetrating wounds through their course, traumatic aneurysms on these arteries are extremely rare. A 75-year-old woman had struck her occipital region against a door but there was no trauma to the mandibuloauricular region. After 1 month, she noticed a pulsatile mass below her right auricle. At operation an aneurysm was found to be located just distal to the origin of the maxillary artery.
由于颈外动脉和上颌动脉的主干在其走行过程中受到良好保护，免受钝性创伤和表浅穿透伤的影响，因此这些动脉上的创伤性动脉瘤极为罕见。一名75岁女性的枕部撞到门上，但下颌耳区未受创伤。1个月后，她注意到右耳下方有一个搏动性肿块。手术中发现一个动脉瘤位于上颌动脉起始部的远端。
