Description
Summary:To discuss the microsurgical anatomy of the carotid bifurcation and the external branch of the superior laryngeal nerve (EBSLN), and to explore the operative techniques in carotid endarterectomy. The carotid bifurcation of 10 cadaveric heads were studied by using microanatomy. We measured the distance. The vertical distance from carotid bifurcation to larynx point and mandibular angle was 24.32 (18.8 ~ 35.78)mm and 13.55 (9.26 ~ 19.60 ) mm. The straight distance from carotid bifurcation to mastoid tip was 68.59 (49.48 ~ 76.94)mm respectively. According to the vertical distance of the larynx point to the carotid bifurcation, the height of the bifurcation of the carotid artery was consistent with the results of the Wain measurement (K = 0.90), the difference was statistically significant (P
