Area of Science:

  • Medical Imaging
  • Sleep Medicine
  • Respiratory Mechanics

Background:

  • Obstructive sleep apnea (OSA) pathogenesis, biomechanics, and treatment efficacy are complex.
  • Understanding upper airway (UA) structure and function is vital for OSA management.
  • Imaging studies offer significant insights into UA anatomy and dynamics during wakefulness and sleep.

Purpose of the Study:

  • To review the role and advancements of upper airway imaging in OSA.
  • To highlight how imaging aids in studying OSA mechanisms and treatment outcomes.
  • To discuss the evolving clinical applications of upper airway imaging.

Main Methods:

  • Nasopharyngoscopy
  • Cephalometrics
  • Computed Tomography (CT)

Related Experiment Videos

  • Magnetic Resonance (MR) imaging

    • Main Results:

    • Imaging modalities reveal static and dynamic UA structure and soft-tissue characteristics.
    • MR imaging and CT enable precise 3D quantification of the UA and surrounding tissues.
    • Studies demonstrate the impact of respiration, weight loss, dental appliances, and surgery on the UA.

    Conclusions:

    • Upper airway imaging is indispensable for understanding OSA.
    • CT and MR imaging provide detailed anatomical and functional data.
    • Clinical indications for UA imaging are expanding, particularly for dental appliance and surgical interventions.
