Surgical success for obstructive sleep apnea (OSA) depends on identifying sites of obstruction in the upper airway. In this study, we investigated sites of obstruction by evaluating dynamic changes in the upper airway using drug-induced sleep computed tomography (DI-SCT) in patients with OSA. Thirty-five adult patients with OSA were prospectively enrolled. Sleep was induced with propofol under light sedation (bispectral index 70-75), and low-dose 320-detector row CT was performed for 10 seconds over a span of 2-3 respiratory cycles with supporting a continuous positive airway pressure model...

Snoring is a sign of increased upper airway resistance and is the most common symptom suggestive of obstructive sleep apnea. Acoustic analysis of snoring sounds is a non-invasive diagnostic technique and may provide a screening test that can determine the location of obstruction sites. We recorded snoring sounds according to obstruction level, measured by DISE, using a smartphone and focused on the analysis of formant frequencies. The study group comprised 32 male patients (mean age 42.9 years). The spectrogram pattern, intensity (dB), fundamental frequencies (F 0), and formant frequencies (F 1, F 2, and F 3) of the snoring sounds were analyzed for each subject...

We studied upper airway structural changes induced by continuous positive airway pressure (CPAP) in obstructive sleep apnea syndrome (OSAS) patients using drug-induced sleep endoscopy (DISE). This prospective study was conducted at an academic secondary referral center. In total, 28 male OSAS patients (mean age 41.1 years) with only retropalatal level obstructions were enrolled. Measurements of the obstruction site were obtained in two steps: first a measurement was taken of the obstruction site in accordance with sleep apnea, then, a measurement was taken of the obstruction site in accordance with DISE-assisted CPAP titration, including quantitative changes in the occlusion site before and after CPAP in pixel format using an area calculation program...
