Summary
Intubation can cause arytenoid cartilage dislocation, especially in patients with specific anatomical factors or inexperienced intubators. Early consideration and preparedness for airway issues are crucial.
Area of Science:
- Anesthesiology
- Otolaryngology
Background:
- Arytenoid cartilage dislocation is a potential complication of endotracheal intubation.
- This injury can lead to significant airway morbidity.
Observation:
- Three case reports detail morbidity from intubation-induced arytenoid cartilage dislocation.
- Risk factors include retrognathia, dental malocclusion, large tongue base, and intubation inexperience.
Findings:
- Difficult intubation increases the risk of arytenoid cartilage dislocation.
- Prompt recognition and management are essential for patient outcomes.
Implications:
- Clinicians should consider arytenoid dislocation after difficult intubations.
- Availability of a ventilating bronchoscope is recommended for managing acute airway problems post-extubation.
- A multidisciplinary approach involving anesthesiology and ENT specialists optimizes treatment.
