Morphological Features of Lymphoid Structures of Nasooropharynx in Children with Hyperplasia of Pharyngeal Lymphoid Ring

Abstract

The purpose is the features of the immunomorphofunctional organization of the adenoids in children with pharyngeal lymphoid ring hyperplasia were defined. The study included 54 children (random sample) from 3 to 7 years examined for the pharyngeal tonsil hypertrophy. Among the 54 selected children, there were 28 (52 %) boys and 26 (48 %) girls. The cause for surgical removal of the adenoids was the ineffectiveness of conservative therapy. The materials for morphological studies were adenoids of children obtained after adenoidectomy. When analyzing the anamnesis of 54 children with adenoid vegetations aged 3 to 7 years, it was found that among patients with this pathology, those aged 4–6 years predominated. The degree of hypertrophy of the pharyngeal tonsil was the highest among preschool children. Morphometric study of adenoids revealed a reciprocal relationship («scissors») between the relative areas of the follicular and diffuse lymphoid tissue, with a reduction in the length of the zone of lymphoepithelial symbiosis, and an increase in the length of the respiratory epithelium, with preserved local reactive sites.
