Abstract
- There are many reports on the variation of origin site of the lingual artery branching from the external carotid artery. However, there are few reports systematically investigating the course of the lingual artery in detail from branching site to the body of tongue. The purpose of this study is to classify systematically the courses of the lingual artery including variations. Using 111 body sides of 63 Japanese cadavers for dissection practices, the lingual artery and the surrounding structures were investigated gross anatomically. The courses of the lingual artery were classified into five types based on the positional relationships with the hyoglossus and the mylohyoid as follows; type M: coursing medial to the hyoglossus (normal course, 104 sides), type L: coursing lateral to the hyoglossus (2 sides), type T: transferring its course from lateral to medial to the hyoglossus (2 sides), type P: penetrating the mylohyoid (2 sides), and type C: the coinciding of types M and P (1 side). Types L, T, P, and C were considered to be variant lingual arteries. Types M and T, type L, and type P arose from the external carotid, facial, and submental arteries, respectively. In types L and P, adding to the variant lingual artery, the remnant of the normal lingual artery was also observed. The present study provides detailed information on the courses of lingual artery which will be of clinical importance especially in the super-selective arterial angiography.
