The identification of features topography of neck's vessels in the prevention of bleedings at surgical interventions on a pharynx

Knowledge of topography and syntopy of neck’s vessels is necessary when carrying out surgical interventions on ENT organs, in particular on palatine tonsils, a larynx, Eustachian tube and a nasopharynx. Authors have studied a anatomo-topographical features of large neck’s vessels in relation to the pharynx’s structures according to MRI-researches that allows to plan tactics of surgical treatment of patients and carry out prevention of hemorrhagic complications. 109 patients (the 218th palatine tonsils) with chronic tonsillitis (64 women and 45 men) aged from 15 up to 54 years are examined. To all patients MRI-diagnostics of neck’s vessels in the vascular mode was carried out, and measurements from the revealed vessels to the capsule of palatine tonsils at the level of the upper and lower poles and in the field of an average third of a palatine tonsil were performed. The distance from external carotid artery to the upper pole of a palatine tonsil makes 17,1 ± 1,01 mm, to the lower pole - 10,3 ± 0,18 mm, in the field of an average third - 10,7 ± 0,12 mm; the distance from internal carotid artery to the upper pole of a palatine tonsil makes 14,5 ± 0,84 mm, to the lower pole - 16,8 ± 0,77 mm, to an average third of a palatine tonsil - 15,3 ± 0,07 mm...
