The following are examples of various uvulopalatopharyngoplasty and hypopharyngeal modifications for select dynamic airway findings seen on DISE:

  • Lateral collapse of the oropharyngeal airway - Expansion sphincter palatopharyngoplasty (Tucker/Pang source)

  • Oropharyngeal anterior-to-posterior collapse - Uvulopalatal flap, anterior palatoplasty

  • Oropharyngeal concentric collapse - Combination of lateral and anterior-to-posterior collapse techniques, Z-palatopharyngoplasty

  • Hypopharyngeal base of tongue collapse - Submucosal minimally invasive lingual excision (SMILE), radiofrequency ablation of the base of tongue

  • Epiglottic collapse - Hyoid suspension (this also helps with lateral hypopharyngeal collapse)

Sleep endoscopy is a great tool for teaching others about airway management, and it is helpful for anesthesiology and otolaryngology residents who are learning about airway anatomy and physiology.
