OSA or Obstructive sleep apnea is the most common type of sleep apnea and is characterized by what causes the stop or pause on breathing, in this case, a muscle may be blocking the air path. It shows repeated episodes of complete or partial obstructions of the upper airway during sleep, despite the effort to breathe, and is usually associated with a reduction in blood oxygen saturation.
When you are getting diagnosed with OSA in-lab tests or at-home testing is suggested. An upper airway imaging is currently not part of the routine diagnostic evaluation for obstructive sleep apnea (OSA) because it can neither confirm nor exclude the disorder.
Despite this, upper airway imaging has several important roles:
There are a variety of imaging techniques that have been used to assess upper airway size and function in patients with OSA. Each technique has certain advantages and limitations. Many of the imaging techniques study awake and upright patients, whereas OSA typically occurs while the patient is asleep in the supine position. Upper airway imaging may identify specific upper airway abnormalities that cause OSA.
It is best to consult and discuss with your doctor your preferred way of treating your OSA as well as the steps on diagnosis
