摘　　要：为了避免腮腺外科手术过程中损伤面神经，对３１具成年尸体（５７侧）腮腺内下颌后静脉与面神经关系进行解剖学研究。结果如下：下颌后静脉直径５．６±１．０ｍｍ。下颌后静脉位于面神经上、下干（或上、中、下干）内侧有５０侧（８７．８％）；位于面神经上干内侧，而在下干外侧有７侧（１２．３％）。依据下颌后静脉横过面神经不同部位，又分成若干亚型。其中较为常见者为下颌后静脉在面神经总干分支点与下干分支点之间的内侧横过（３３．３％）。在２６具双侧解剖的尸体中，有４例（１５．４％）下颌后静脉与面神经关系左。In order to provide morphological basis for the parotid surgery, the relationship between the intraparotid retromandibular vein and the facial nerve in 31 cadavers (57 sides) were investigated. The results showed that the retromadibular vein was 5.6±1.0 mm in diameter in 50 sides (87.7%), and it was located on the medial side of the upper and lower trunks (0r the upper, middle and lower trunks) of the facial nerve, and it was medial to the upper trunk and lateral to the lower trunk in 7(12.3%). The most commonly encountered variation was that retromandibular vein crossed the facial nerve medially (33.3%) at a point between the bifurcation and ramification points of the lower facial trunk. The course of the retromandibular vein was different in right and left sides in 4 cases (15.4%) of the 26 cases.
