Abstract:
The Maxillary artery is a component of the terminal branch of external carotid artery and distributes the blood flow to upper and lower jawbones and to the deep facial portions. It is thus considered to be a blood vessel which supports both hard and soft tissues in the maxillofacial region. The maxillary artery is important for bleeding control during operation or superselective intra-arterial chemotherapy for head and neck cancers. The diagnosis and treatment for diseases appearing in the maxillary artery-dominating region are routinely performed based on image findings such as CT, MRI and angiography. However, validations of anatomical knowledge regarding the Maxillary artery to be used as a basis of image diagnosis are not yet adequate. In the present study, therefore, the running pattern of maxillary artery as well as the type of each branching pattern was observed by using 28 sides from 15 Japanese cadavers. In addition, we also took measurements of the distance between the bifurcation and the origin of the maxillary artery and the inner diameter of vessels. These findings thus obtained could contribute to knowledge of improved accuracy of image diagnosis as an index for embolization and for knowledge of an adequate superselective intra-arterial chemotherapy.
