Abstract

Objective: To investigate the clinical and swallowing profiles of patients with post-intubation tracheal or laryngotracheal stenosis requiring tracheostomy prior to surgical or corrective airway interventions.

Methods: A retrospective cohort clinical study. Patients who met the inclusion criteria underwent a swallowing evaluation, as well as imaging studies of the neck and chest. At 6 and 12-months after the initial assessment, all patients participated in follow-up speech pathology consultations to evaluate the current state of swallowing and the progress of airway stenosis treatment.

Results: Twenty-five patients with a median tracheostomy duration of 30.52 months were assessed. The study found a female predominance (68%) and a high prevalence of subglottic stenosis (44%). Most patients required intubation due to severe acute respiratory failure and airway protection due to a decreased level of consciousness. Imaging revealed additional airway abnormalities, including laryngotracheobronchitis and laryngeal edema. Swallowing assessments showed that 20% had significant dysphagia. After one year, only two patients were successfully decannulated, while others remained tracheostomy dependent.

Conclusion: The study underscores the need for personalized, multidisciplinary care for these patients. It finds that while treatments like reconstructive surgeries and the Montgomery T-tube can be effective, complications such as clinical instability and dysphagia can worsen outcomes and extend the need for tracheostomy.
