口外结扎舌动脉虽非惯常措施,但有时的确需要 如此以阻止各种原因引起的口内无法控制的出血。可经颈前部两个大的解剖三角之一颈动脉或颌下三角将其结扎。有几个位于上述两区域内的小的次级三角与舌动脉的结扎有着特殊的关系,最常涉及的是Béclard’s三角、Lesser’s三角和Pirogoff’s三角。这些名称虽已应用近百年,就其确切的解剖边界仍存有争论和混乱。本调查目的即在于描述舌动脉的位置变异及 Although it is not the usual practice to ligulate the tongue outside the mouth, it is sometimes necessary to do so to prevent uncontrollable bleeding in the mouth caused by various causes. It can be ligated through one of the two large anatomic triangles in the anterior neck of the carotid artery or submandibular triangle. There are several small secondary triangles in the above two regions that have a special relationship with the ligation of the lingual arteries, most commonly the Béclard’s triangle, the Lesser’s triangle, and the Pirogoff’s triangle. Although these names have been used for nearly a hundred years, there are still controversies and chaos on the exact boundaries of their anatomy. The purpose of this survey is to describe the location of tongue arteries and variability
