ESTRADA-BRIZUELA, Yarima et al. Characterization of laryngeal-tracheal stenosis. AMC [online]. 2020, vol.24, n.3, e7148.  Epub June 01, 2020. ISSN 1025-0255.


the increase in the number of cases with laryngeal-tracheal stenosis is a concern in the present and future of medical practice.


to characterize laryngeal-tracheal stenosis.


a retrospective longitudinal analytical study was carried out, with the objective of characterizing the laryngeal-tracheal stenosis at the Octavio de la Concepción y de la Pedraja Teaching and Surgical Clinical Military Hospital of Camagüey from January 2014 to January 2019.The universe was composed by 12 patients diagnosed with laryngeal-tracheal stenosis.


in the study the average age was 40.6 years, in terms of gender there was equality for both, the main cause of laryngeal-tracheal stenosis was post-intubation, the location of the most frequent stenosis was subglottic. The severity of the stenosis was proportional to the days of permanence of artificial ventilation. The majority of patients presented grade III stenosis according to Cotton's classification.


laryngeal-tracheal stenosis is a complication whose most frequent causes are avoidable. External trauma and most often endogenous trauma by intubation are the most frequent and can be eludedmostly. The epidemiology exerts little influence on the appearance of stenosis, the length of time of the tube, was a factor associated with the greater number of patients.
