The article presents the results of pre-surgery study of intranasal arteries location in 128 patients with various types of skull structure. It was found that in patients with brachycephalia, the branches of the external carotid artery dominate — a. sphenopalatina (posterior nasal septal artery and lateral (aa. nasales posteriores laterales et septi), providing blood supply to the posterior sectors of the nasal cavity, both the lateral and medial walls of the nasal cavity. In patients with dolichocephalia, the branches of the internal carotid artery dominate, i.e. the front and rear lattice arteries (aa. ethmoidales anterior et posterior), which provide blood to the ethmoidal labyrinth and the front sections of the nasal cavity. No predominance of arterial blood flow type was observed in patients with mesocephalia. The obtained data allowed to elaborate a method of intraoperative nasal bleeding prediction. If a patient belongs to dolichocephalic type, the bleeding from the anterior sectors of nasal cavity can be expected. If the patient belongs to brachycephalic type, there is a risk of bleeding from the posterior sectors of nasal cavity. In patients with mesocephalia bleeding can occur from both the front and posterior sectors of nasal cavity.

Key words: blood supply of a nose, cephalic indicator, epistaxis.
