Introduction:

Laryngotracheal stenosis describes a condition of upper airway obstruction that is generally more frequently associated with prolonged processes of endotracheal intubation or scarring after a tracheostomy.

Objective:

Determine the clinical-surgical characterization of patients with a diagnosis of laryngotracheal stenosis in the Otorhinolaryngology Service of the Hospital de Clínicas.

Methodology:

An observational, descriptive, retrospective study with crossed association was carried out. Data were collected from clinical records: diagnostic method, level of stenosis, degree of stenosis according to Cotton-Myer (1994), intubation time, primary treatment performed, use of mitomycin C, T-tube placement, complications and recurrence. In addition, reinterventions were performed and stenoses were classified as simple or complex.

Results:

A total of 65 records were reviewed, of these, 42 patients were included, with a predominance of males, with a mean age of 32.76±13.84 years. The most affected anatomical site was the tracheal. Regarding the degree of stenosis, according to the Cotton-Myer classification, it was found that 54% had grade III stenosis. Most patients underwent endoscopic treatment, only 9.5% underwent surgical treatment.

Discussion:

Laryngotracheal stenosis is a difficult problem to manage and often requires a sequential series of repetitive interventions. The vast majority of stenosis acquired in adults originate from endotracheal intubation. In this study, only patients with this history were included, ruling out another cause of stenosis. The most frequent level of stenosis was tracheal, this differs from other studies Gómez (2013), Ramírez (2018) where the most affected site was subglottis. The most frequently found grade of stenosis was III (54%), also different from other studies Nikolovski (2019), Ramírez (2018) and Ghiani (2022), in which grade I was more frequent.
