Abstract:
The present article was designed to report a case of the surgical treatment of the patient presenting with extended laryngotrachealstenosis related toosteochondroplasticlaryngo- and tracheopathy. The development of the osteochondroplastic transformation of the laryngeal and tracheal walls was regarded as a single pathomorphologicalprocess associated with chronic inflammation. The study has demonstrated the relationship between the squamous cell hyperplasia in the epithelium of the upper respiratory tract and destructive chondro-perichondritis of the larynx and trachea accompanied by osteochondroplastic changes and concomitant extended laryngotracheal stenosis.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
