[Histomorphology and histochemistry of acquired scars of the laryngo-tracheal regions in children].
Acquired scars of the tracheolaryngeal compartment dissected during surgery of 28 children (35 samples) were taken under histological and histochemical examination. In most cases, scar tissues-showed signs of chronic inflammatory infiltration, pronounced changes of the microcirculatory bed, dystrophic and destructive processes, continuous formation of granulation foci and subsequent fibrosis, fibrotic changes in muscles and noticeable dystrophic and metaplastic changes of the epithelium. This points to changes in the relationship between inflammation and regeneration and persistence of inflammatory, sclerotic and dysplastic processes which may cause recurrent development of stenotic scars after their removal.
