[Optimization of the surgical methods for the treatment of recurrent nasal bleeding (a pathologo-anatomical study)]

The objective of the present work was to study specific features of blood supply to the nasal cavity by staining mandibular and ethmoidal arteries to reveal their size and topographic features under conditions of a pathologo-anatomical department. The secondary objective was to modify the existing and develop new methods for the ligation of these vessels. This pathologo-anatomical study was based on 16 preparations examined with the use of up-to-date optical facilities. The results of investigations of the topographo-anatomical peculiarities of blood supply in the nasal cavity are supplemented by the evaluation of the potential of endoscopic rhinosurgery for the treatment of recurrent nasal hemorrhage. The methods for endoscopic ligation of mandibular and ethmoidal arteries have been developed and optimized.
