[Extended laryngotracheal stenosis and osteochondroplastic tracheopathy].

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.
