Clinical Definition

Arytenoid cartilage characteristics:

  • Paired Structures: Two pyramid-shaped cartilages
  • Vocal Cord Attachment: Posterior attachment point for vocal cords
  • Mobile Joints: Articulate with cricoid cartilage
  • Muscle Attachments: Control vocal cord tension and position
  • Airway Function: Influence vocal cord position and airway patency

Arytenoid abnormalities can affect vocal cord function and potentially contribute to breathing difficulties during sleep.

Etymology & History

Arytenoid cartilages have been recognized anatomically since ancient times, with their function in voice production and airway control being understood through modern laryngology.

Reference Values & Interpretation

Normal Values

Normal arytenoid cartilages should allow appropriate vocal cord movement and positioning without causing airway obstruction or voice problems.

Abnormal Values

Abnormal arytenoid cartilages may include fixation, dislocation, or other abnormalities affecting vocal cord function and potentially breathing.

How It's Measured

Arytenoid cartilages are assessed through laryngoscopy, CT imaging, and functional assessment of vocal cord movement and positioning.

Role in Diagnosis

Arytenoid assessment is important when evaluating vocal cord dysfunction that may contribute to breathing problems or voice changes.

Role in Treatment

Arytenoid abnormalities may be treated with voice therapy, surgical procedures, or other interventions to restore normal function.
