Arytenoid dislocation (AD) can occur during intubation. This case report highlights the risk of AD when using a McCoy laryngoscope, even in difficult intubations.

Area of Science:

  • Laryngology
  • Anesthesiology
  • Surgical Innovation

Background:

  • Arytenoid dislocation (AD) is a disruption of the cricoarytenoid joint.
  • Accurate diagnosis and management of AD are crucial for vocal function.
  • Laryngeal cartilage positioning is key to normal voice production.

Observation:

  • A case of arytenoid dislocation (AD) occurred during endotracheal intubation.
  • The McCoy laryngoscope was used in this specific intubation procedure.
  • The device is generally considered useful for challenging intubations.

Findings:

  • The McCoy laryngoscope may increase the risk of arytenoid dislocation (AD).
  • Malpositioning of arytenoid cartilages (AC) can result from device use.
  • Complete disruption of the cricoarytenoid joint is a potential complication.

Implications:

  • Clinicians should be aware of the potential for AD with McCoy laryngoscopes.
  • Further research is needed to assess the incidence of AD with this device.
  • This finding may influence the choice of laryngoscope in certain clinical scenarios.
