Clinical Definition

Supraglottic structures include:

  • Epiglottis: Leaf-shaped cartilage covering the larynx
  • Aryepiglottic Folds: Connecting arytenoids to epiglottis
  • Ventricular Folds: False vocal cords
  • Arytenoid Cartilages: Posterior laryngeal cartilages
  • Laryngeal Vestibule: Space above vocal cords

Supraglottic abnormalities can cause inspiratory stridor and may contribute to complex sleep-disordered breathing patterns.

Etymology & History

Supraglottic structures have been recognized anatomically since ancient times, with their role in sleep-related breathing disorders becoming understood with modern laryngoscopy.

Reference Values & Interpretation

Normal Values

Normal supraglottic structures should maintain appropriate size and position without causing significant airway obstruction or breathing difficulties.

Abnormal Values

Abnormal supraglottic structures may include enlargement, malposition, or excessive collapse causing supraglottic obstruction and breathing problems.

How It's Measured

Supraglottic structures are assessed through flexible laryngoscopy, direct laryngoscopy, and sometimes specialized imaging or sleep endoscopy.

Role in Diagnosis

Supraglottic assessment is important when evaluating complex upper airway obstruction, particularly cases with inspiratory stridor or laryngeal involvement.

Role in Treatment

Supraglottic abnormalities may be treated with medical management, surgical procedures, or specialized interventions depending on the specific condition.
