Abstract

In order to clarify the topographical morphology of the Korean lingual artery related to clinical problems, authors investigated the morphological variations of the lingual artery through the dissection of the deep layer of head and neck 61-s1des of Korean adult cadavers (mean age 57 8) were used for this studyThe morphlogy of the origin Sties of the lingual artery were classified into three types The cases that the superior thyroid, lingual, and facial artery were originthers were the cases that the lingual artery and the facial artery were divided from the linguofacial trunk (31 2%), and the cases that the superior thyroid artery and the lingual artery were divided from the thyreolingual trunk (12 5%) from the external carotid artery, respectively In the topographical relationships between the first part of the lingual artery and the hyoglossus muscle, the cases that the first part of the lingual artery formed loop posterior to the hyoglossus muscle (41 2%) and the cases that the lingual artery penetrated into the medial aspect of the hyoglossus muscle passing the posterior border of this muscle (66 1%) were observed most frequently Others were the cases that the lingual artery penetrated into the postenor muscle fIber (18 6%) and the middle muscle fiber (15 3%) of the hyoglossus muscle The courses of the second part of the lingual artery deep to the hyoglossus muscle could be classified into two morphlogical types One was that the second part of the lingual artery ran superiorly from the origin site and then turned abruptly towards deep portion of hyoglossus muscle In these cases, the artery turned upward again at the inside of the muscle, and then reached to the sublingual region (42 6%) The other cases were that the lIngual artery ran gradually to the medial and supenor aspect of the sublmgual region (57 4%) The prevalency of the sublingual arteries originating from the lingual arteries was 59% Taken all together, authors concluded that the mouth floors of Korean are supplied by both the lingual and facial artery So, performing the hemostatic procedures m the mouth floor region, the surgeon must take a topographical anatomy of this region related the arterial supply into account
