Arterial Blood Supply of the Nose and the Pharynx: An Angiographic Study

Abstract

The main blood supply of the nose and the pharynx comes from internal and external carotid arteries by different branches that may have different courses, relations and anatomical variations. Knowledge of these variations leads to effective management of many ENT disorders and precise surgical control. Although these variations are mentioned in some literature, the idea of the study wasn’t done before and some variations are listed for the first time. To the best of our knowledge, this study has the largest number of patients studying different anatomical variations. The aim of our study is to define origin, number, target and branches of the arteries supplying the nose and the pharynx and know related different anatomical variations and their percentage. All cases of o
