本研究的目的是对人类舌下动脉的走向进行分类。为此，我们使用 53 具尸体的 101 侧对供应口底和舌头的动脉进行了总体解剖学研究。这些路线分为三类：穿过舌骨内侧或外侧的（M类和L类）和穿过下颌舌骨肌的（P类），又分为五种类型。 M类有一种被认为是通常类型的类型，其中舌动脉采取通常的分布模式。 L型和P型，舌下动脉起源于面动脉或颏下动脉，分别有两种类型，统称为异常型。 101 侧中，分别有 61 侧和 36 侧为常见类型和异常类型，后者包括 17 侧 L 类和 19 侧 P 类。其余 4 侧是舌动脉本身的变异。按性别划分，常见型多见于女性（75.6%），异常型多见于男性（48.1%）。双侧同型多见于常见型（77.4%）和异常型（65.0%）。舌下动脉分支的存在显着增加了颏下动脉的厚度。可以想象，这里提出的分类将有助于更安全的牙种植手术和更准确地解释口底动脉血管造影图像。
The purpose of the present study was to classify the courses of the human sublingual artery. For this purpose, the arteries supplying the floor of the mouth and the tongue were gross anatomically investigated, using 101 sides of 53 cadavers. The courses were divided into three categories: those passing medial or lateral to the hyoglossus (Categories M and L) and that piercing the mylohyoid (Category P), which were subdivided into five types. Category M had one type regarded as the usual type in which the lingual artery took the usual pattern of distribution. Categories L and P, in which the sublingual artery arose from the facial or submental artery, had the respective two types and were collectively regarded as the unusual type. Sixty-one and 36 of the 101 sides were of the usual and unusual types, respectively, the latter of which included 17 of Category L and 19 of Category P. The remaining four were variations of the lingual artery itself. On examining the types by gender, the usual type was more often found in females (75.6%), whereas the unusual type was more often found in males (48.1%). Bilateral occurrence of the same type was often found in both the usual type (77.4%) and the unusual type (65.0%). Existence of the sublingual artery branch significantly increased the thicknesses of the submental arteries. The classification proposed here will conceivably contribute to safer dental implant surgery and more accurate interpretation of angiographic images of arteries in the floor of the mouth.
