Keywords:
orotracheal intubation, dilation, stenosis.Abstract
Introduction: Laryngotracheal stenosis is defined as the formation of partial or total scar tissue in the laryngeal or tracheal lumen.
Objective: To characterize laryngotracheal stenosis in patients treated at the National Center for Minimum Access Surgery.
Methods: A longitudinal, descriptive, retrospective, observational study was carried out on patients treated at the National Center for Minimum Access Surgery, between 2017 and 2021.
Results: 31.5% of the patients were between 50 and 64 years old and 65.8% were male. Prolonged orotracheal intubation was the cause of stenosis in 72.6% of cases. In 63% the stenosis was located in the trachea. The average intubation time was 14.2 ± 10.7 days. Dilation was the treatment in 54.7%. Restenosis developed in 17.8%.
Conclusions: Prolonged orotracheal intubation was the cause of laryngotracheal stenosis in the vast majority of cases. All patients were intubated via the orotracheal route with an average time of around 15 days. Dilation was the most used treatment.
