This study was conducted to describe in detail the branching patterns of cortical branches from the middle cerebral artery supplying the feeding of the temporal region, to define the arterial structure of temporal artery (TA) and to determine the effect of this arterial supply to the temporal region. The arteries of brains (n = 22; 44 hemispheres) were prepared for dissection after filling them with colored latex. TA was defined, and its classification was described, specifying its relationship with other cortical branches. A new classification was defined related to TA terminology. TA was found in 95% of cadavers, and it originated as an early branch in 75% and from the inferior trunk in 24% of cadavers. TA was classified as Type 0: No TA, Type I: single branch providing two cortical branches, Type II: single branch providing three or more cortical branches and Type III: double TA. Type I-TA (45%) was the most common, and Type II-TA arterial diameter was significantly larger than that of other types. All cadavers showed the cortical branches of temporal region from middle cerebral artery, anterior TA , middle TA, posterior TA and temporooccipital artery, except temporopolar artery (81%). Temporopolar artery, anterior TA, and middle TA primarily originated from TA, an early branch, but posterior TA and temporooccipital artery primarily originated from the inferior trunk. Detailed knowledge about cortical branches together with TA and also this region's blood supply would enable increased prediction of complications, especially in cases with these region-related pathologies, and would make interventions safer.
本研究旨在详细描述供应颞区营养的大脑中动脉皮质分支的分支模式，定义颞动脉（TA）的动脉结构，并确定这种动脉对颞区的供应效果。在将大脑的动脉（n=22；44 个半球）用彩色乳胶填充后，对其进行解剖准备。定义了 TA，并对其进行了分类描述，明确了其与其他皮质分支的关系。定义了一个与 TA 术语相关的新分类。在 95%的尸体中发现了 TA，其起源于早期分支的占 75%，起源于下干的占 24%。TA 被分为 0 型：无 TA，I 型：单支供应两支皮质分支，II 型：单支供应三支或更多皮质分支，III 型：双 TA。I 型-TA（45%）最常见，II 型-TA 的动脉直径明显大于其他类型。除颞极动脉（81%）外，所有尸体均显示来自大脑中动脉、前 TA、中 TA、后 TA 和颞枕动脉的颞区皮质分支。颞极动脉、前 TA 和中 TA 主要起源于 TA，即早期分支，但后 TA 和颞枕动脉主要起源于下干。详细了解皮质分支以及 TA 和该区域的血液供应，将能够提高对并发症的预测能力，特别是在与该区域相关的病理情况下，并且会使干预更加安全。
