AGE FEATURES OF THE VASCULAR ORGANIZATION OF THE ADENOID TISSUE

Adenoid vegetations are among the most common pathology of the upper respiratory tract in children. According to some authors, adenoids can occur in the adult population, causing a number of clinically significant symptoms. It is known that intraoperative bleeding in adenotomy in the adult contingent of patients is more pronounced in comparison with patients of child age. Thus, knowledge of the age-specific features of the vascular organization of adenoid tissue is necessary for the development and improvement of sparing methods of surgical treatment of pharyngeal tonsil hypertrophy. The authors examined 96 patients (n = 96), which were divided into 4 groups: 1 group - patients from 7 to 12 years (n = 25); Group 2 - patients from 12 to 15 years (n = 25); Group 3 - patients from 15 to 18 years (n = 25); Group 4 - patients from 18 to 42 years (n = 21). 58 patients were male (60%) and 38 - female (40%). As a result of histological examination of the adenoid tissue, characteristic changes in the vessels of the adenoid tissue in each age group were revealed, which are most pronounced at the age of 15-18 years. There is a development of sclerosis and hyalinosis of the walls of the vessels with the formation of cavernously enlarged full-blood veins with thickened rigid walls. In patients older than 18 years, the morphological reorganization of the connective tissue (basal) layer is observed, manifested by immersion of the lymphoid tissue with a well developed microcirculatory bed, which can explain the pronounced intraoperative bleeding in adenotomy. Thus, the results of the histological examination can serve as one of the indications for the application of electrophysical methods of adenotomy in patients older than 15 years.
