To investigate the effectiveness of CT angiography for detecting perforator vessels in the anterolateral thigh flap surgery.Eight patients with oral and maxillofacial soft tissue defects were repaired with the anterolateral thigh flap. Preoperative CT angiography was conducted to detect perforator vessels. The perforator vessel with large diameter, abundant blood flow, and long pedicle was selected to design the flap.The position of perforator vessels during operation were completely consistent with those detected by CT angiography. The anterolateral thigh flap for 8 cases tally survived.One case had the vascular crisis，which was survived after surgical exploration. The flap ranged from 10 cm×5 cm to 6 cm×4 cm in size. Donor recipient site was not severe complications. CT angiography can be used to locate the perforator vessels preoperatively and accurately，which is beneficial for surgeons to design the flap and reduce surgical complications. The anterolateral thigh flap is an effective method of repairing oral and maxillofacial soft tissue defects.
探讨CT血管造影术在股前外侧皮瓣手术中检测穿支血管的有效性。8例口腔颌面部软组织缺损患者采用股前外侧皮瓣修复。术前进行CT血管造影术以检测穿支血管。选择直径大、血流丰富、蒂长的穿支血管来设计皮瓣。术中穿支血管的位置与CT血管造影术检测到的完全一致。8例股前外侧皮瓣全部成活。1例发生血管危象，经手术探查后成活。皮瓣大小为10 cm×5 cm至6 cm×4 cm。供区和受区均未出现严重并发症。CT血管造影术可在术前准确地定位穿支血管，有利于外科医生设计皮瓣并减少手术并发症。股前外侧皮瓣是修复口腔颌面部软组织缺损的有效方法。
