Minimally invasive treatment is effective in postintubation airway stenosis and obviates the need for open cervicomediastinal surgery in most patients. Patients with old and long lesions are less likely to be cured endoscopically. For most patients in this subgroup, endoscopic surgery makes airway augmentation a viable, less invasive alternative to resection. Patients were unlikely to require further therapy after 6 months of symptom-free follow-up.
Background
Coronavirus disease 2019 critical care patients endure prolonged periods of intubation. Late tracheostomy insertion, large endotracheal tubes and high cuff pressures increase their risk of subglottic and tracheal stenosis. This patient cohort also often appears to have co-morbidities associated with laryngotracheal stenosis, including high body mass index and laryngopharyngeal reflux.
Methods
This paper presents three coronavirus disease 2019 patients who were intubated for a mean of 28 days before tracheostomy, leading to complex multi-level stenoses.
Results
All patients underwent multiple endoscopic tracheoplasty procedures and two required tracheal resections. There was a mean of 33.9 days between interventions. Coronavirus disease 2019 patients do not appear to respond as well to steroid, laser and balloon dilatation as other adult stenosis patients.
Conclusion
Intubated coronavirus disease 2019 patients have an increased risk of laryngotracheal stenosis, as a result of multiple factors. Otolaryngology teams should be vigilant in investigating for this complication. International guidelines on time to tracheostomy should be followed, despite a diagnosis of coronavirus disease 2019.
CO2 laser-assisted endoscopic excision of a laryngocele is a quick, precise, and safe alternative to an external approach excision (lateral thyroidotomy, laryngofissure) with fewer complications than its external counterparts, resulting in speedier rehabilitation of both the patient and his or her voice.
