根据颈动脉在岩骨内走行与颅底标志的关系,可避免在手术中造成神经、血管灾难性的并发症。作者随机选择100例成人颞骨的组织切片进行显微观察,并在10具成人新鲜尸体上对岩骨内颈动脉进行解剖和显微测量。颈动脉在颈静脉孔的前方进入颅底;颅中窝孔位于岩尖的前内方。据此人为地将颈动脉分为垂直段、膝部和水平段。垂直段长约5.0～12.5mm(平均为9.35mm),直径4.0～7.5mm(平均为(5.7mm)。该段的下部易于辨认,系在茎突
According to the carotid artery in the petrous bone and skull base mark the relationship between the operation to avoid nerve, vascular catastrophic complications. The authors randomly selected 100 adult temporal bone tissue sections for microscopic observation and anatomical and microscopic measurements of the petrous carotid artery on 10 adult fresh cadavers. The carotid artery enters the base of the skull in front of the jugular foramen; the cranial fossa is located in front of the petrous apex. Artificially divided into carotid artery vertical section, knee and horizontal section. The vertical section is about 5.0 to 12.5 mm (average 9.35 mm) with a diameter of 4.0 to 7.5 mm (an average of 5.7 mm). The lower part of this section is easily identifiable,
