摘　　要：目的应用计算机断层X线血管造影术(CTA)影像测量面横动脉与髁突周围手术的解剖位置关系,为在下颌骨髁突骨折手术及腮腺手术中寻找或避免损伤面横动脉提供指导。方法选择35名正常成人下颌骨髁状突及面横动脉CTA扫描图像,应用ADW4.2图像处理软件测量颧弓中点上缘距面横动脉、颞骨关节结节最低点距面横动脉以及关节窝顶点(最高点)距面横动脉的距离的解剖位置。结果颧弓中点上缘距面横动脉的距离为(27.90±2.68)mm;颞骨关节结节最低点距面横动脉的距离为(15.15±2.42)mm;关节窝顶点距面横动脉的距离为(23.95±2.76)mm。左右无统计学差异(P>0.05)。结论在做下颌骨髁突手术时采用耳屏前切口或耳屏-颌下联合切口时容易损伤面横动脉;参照测量获得的解剖数据以及测量时的定位点可以为术前体表确定面横动脉的基本位置及在术中定位解剖面横动脉的准确位置提供帮助,进而可以在髁突骨折手术中提前结扎面横动脉,防止术中损伤而引起不必要的大量出血或在术中直接避开面横动脉从而保留其功能。Objective To research the anatomical position relationship between transverse facial artery and surrounding condylar process operation by computer tomography angiography （CTA） so as to provide guide to search for transverse facial artery or avoidance its injury during operation for condylar process fracture and parotid gland. Methods A total of 35 normal adults＇ CTA scanograms of mandibular condylar process with transverse facial artery were enrolled in the study. Imaging manipulation software （ ADW4.2 ） was used to measure the distances from transverse facial artery through the midpoint superior border of zygomatic arch, the lowest point of temporal bone articular tubercle, and the highest point of the glenoid fossa. Results The length from transverse facial artery through the three points was 27.90 ± 2.68,15.15 ± 2.42 and 23.95 ± 2.76mm, respectively. There was no significant deviation about left and right. Conclusion The incision in front of tragus or the incision of combined tragus-submaxilla may lead to injury of transverse facial artery during the operation about mandible condylar process. With the measured disseetional data and the anchor point, transverse facial artery can be approximately positioned before surgery and located during operation and then ligated for prevention from injury and excessive bleeding, or it may be kent away for its functional reserve accordingly.
