目的研究颞肌动脉血供情况。方法选用10具成人新鲜头颅标本,将其标本浸泡在10%的甲醛溶液中,于颈总动脉中灌注1∶1的乳胶与硫酸钡的混合液,将头颅标本去除颞区的皮肤与皮下组织后将颞肌取下,在2.5mA40kV的牙片机下摄颞肌血供X线片,并对其血供来源动脉进行观察分析。结果供应颞肌的主要动脉有3条:颞深前动脉,供应颞肌前份,约占全部颞肌的11%~25%,平均为17%;颞深后动脉,供应颞肌中份,约占全部颞肌的27%~50%,平均为38%;颞肌内动脉,为颞浅动脉的分支,供应颞肌的后份,约占全部颞肌的30%~58%,平均为45%。结论研究结果给以提示,在制备颞肌瓣来修复口腔颌面部缺损时,可根据其血供动脉分支来源制备3个不同的组织瓣,即前颞肌瓣、中颞肌瓣和后颞肌瓣或反向颞肌瓣。
Objective To study the temporal arterial blood supply. Methods Ten adult fresh skull specimens were selected and immersed in 10% formaldehyde solution. The carotid artery was infused with a 1: 1 mixture of latex and barium sulfate. The skull specimens were removed from the temporal skin and subcutaneous tissue After the removal of the temporal muscle, in the 2.5mA40kV tooth machine to take the temporal muscle blood supply for X-ray film, and its blood supply artery was observed and analyzed. Results There were 3 main arteries supplying temporalis muscle: anterior deep temporal artery, anterior temporalis supply, accounting for 11% ~ 25% of all temporalis muscles, with an average of 17%; temporal deep posterior arteries, Accounting for about 27% to 50% of the total temporalis muscle, with an average of 38%. The temporal intramuscular artery, which is a branch of the superficial temporal artery, supplies the posterior portion of the temporalis, accounting for about 30% -58% of the total temporalis muscle, with an average of 45%. Conclusions The results of this study suggest that in the preparation of the temporal muscle flap for the repair of oral and maxillofacial defects, three different tissue flaps, namely the anterior temporal muscle flap, the medial temporal muscle flap and the posterior temporal artery, can be prepared according to the origin of the blood supply artery branch Muscle flap or reverse temporal muscle flap.
