Risk Factors

  • Prolonged intubation
  • Size of the tube, material
  • Care of intubated patient
  • High-pressure cuffs tube
  • Difficult intubations
  • Multiple intubations
  • GERD
  • Tracheobronchial infection

Pathophysiology

  • Laryngeal ➔ granulation tissue ➔ ulceration ➔ perichondritis ➔ subglottic stenosis

Treatment

  • Grade I & II: Observation, balloon dilation, laser excision
  • Grade III & IV: Tracheostomy, laryngotracheal reconstruction, cricotracheal resection
