Arytenoid dislocation.

Area of Science:

• Otolaryngology
• Anesthesiology
• Emergency Medicine

Background:

• Arytenoid cartilage dislocation is an uncommon injury.
• The cricoarytenoid joint's mobility and capsule laxity typically prevent dislocation.
• Previous literature suggested predisposing factors were necessary for dislocation during endotracheal intubation.

Observation:

• Three cases of arytenoid cartilage dislocation following endotracheal intubation are presented.
• Painful swallowing was the primary symptom in all cases.
• Clinical features distinguishing dislocation from vocal cord paresis are outlined.

Findings:

• Endotracheal intubation can cause arytenoid cartilage dislocation, even without apparent predisposing factors.
• The presented cases highlight a direct link between intubation and dislocation.
• Specific techniques for early reduction under local anesthesia are detailed.

Implications:

• This study challenges the notion that endotracheal intubation alone is insufficient to cause arytenoid dislocation.
• Early diagnosis and management are crucial for patient recovery.
• The findings provide valuable information for clinicians managing airway procedures and potential complications.
