目的：本研究的目的是通过翼腭窝区域的连续尸体解剖来描绘上颌动脉及其分支动脉，并开发各种分支模式的分类。 材料和方法：使用 15 具韩国成人尸体；检查每具尸体的 2 侧，总共 30 侧。在解剖翼腭区域之前，对 20 具尸体头部进行了计算机断层扫描。本研究制作了尸体头部 9 面厚度为 3.0 毫米的切片标本。然后我们在显微镜下解剖了新鲜尸体的21面。在这项研究中，我们观察了上颌动脉第三部分的分支模式、上颌动脉终末分支与翼上颌交界处的关系以及腭降动脉的走行。然后我们对上颌动脉在翼腭窝的分支方式进行了分类。结果：从翼上颌交界处到翼腭窝区域，上颌动脉通常按以下顺序分为5条动脉：后上牙槽动脉、眶下动脉、翼管动脉、腭降动脉和上颌动脉。 蝶腭动脉。在 21 具尸体中，有 18 具表现出这种顺序（85.7%）。上牙槽后动脉和眶下动脉有2种分支模式。翼上颌结合部最低点到后上牙槽动脉、眶下动脉和腭降动脉的平均距离分别为15.2、32.2和24.8毫米。在大多数情况下（95.2%），腭大动脉和腭小动脉是从腭降短动脉中分离出来的。根据上颌动脉第三部分的轮廓，将其分为5种类型：“Y”型（19%）、“中间”型（33.3%）、“T”型（23.8%）和“M”型（14.3%）。结论：本次调查结果显示了上颌动脉的常见模式。 (C) 2003 年美国口腔颌面外科医师协会。
Purpose: The purposes of this study were to delineate the maxillary artery and its branching arteries and to develop a classification of the various branching patterns by means of serial cadaver dissections of the pterygopalatine fossa region.Materials and Methods: Fifteen Korean adult cadavers were used; 2 sides of each cadaver were examined, for a total of 30 sides. Before dissection of the pterygopalatine region, computed tomography scan was taken of 20 cadaver heads. Sectioned specimens of 9 sides of the cadaver heads in 3.0-mm thickness were made for this study. Then we dissected 21 sides of fresh cadavers under the microscope. In this investigation, we observed branching patterns of the third portion of the maxillary artery, a relationship of the terminal branches of the maxillary artery to the pterygomaxillary junction, and the course of descending palatine artery. Then we classified the branching patterns of the maxillary artery in the pterygopalatine fossa.Results: From the pterygomaxillary junction to the pterygopalatine fossa region, the maxillary artery was usually branched into 5 arteries in the following order: posterior superior alveolar artery, infraorbital artery, artery of the pterygoid canal, descending palatine artery, and sphenopalatine artery. Of 21 cadavers, 18 showed this order (85.7%). There were 2 types of branching patterns of the posterior superior alveolar artery and the infraorbital artery. The average distance from the most inferior point of the pterygomaxillary junction to the posterosuperior alveolar artery, infraorbital artery, and descending palatine artery was 15.2, 32.2, and 24.8 mm, respectively. In most cases (95.2%), the greater and lesser palatine arteries were divided from the short descending palatine artery. According to the contours of the third portion of the maxillary artery, we classified them into 5 types: the "Y" type (19%), "intermediate" type (33.3%), "T" type (23.8%), and "M" type (14.3%).Conclusion: The results of this investigation show the common patterns of the maxillary artery.
