Arytenoid dislocation.

C A Quick, G E Merwin

    Summary
    This summary is machine-generated.

    Arytenoid cartilage dislocation is rare but can occur after endotracheal intubation. Early reduction under local anesthesia is recommended for this condition, which causes painful swallowing.

    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.

    Related Experiment Videos

  • 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.
