The role of video-fluoroscopy in the assessment of obstructive sleep apnea patients: comparative study

Abstract Background Pre-operative imaging tools play a crucial role in the anatomic assessment of upper airway and adjacent structures obstructive sleep apnea patients. The current study was aimed at comparing correlating results videofluoroscopy evaluating obstruction surgically fit “OSA” patients with fiberoptic nasoendoscopic examination during awake “Muller’s maneuver” induced propofol for better selection suitable surgical maneuver. present an observational cross-sectional 69 OSA (36 males 33 females); their ages ranged between 29 65 years mean age 45.87 ± 9.68 years. were selected from otorhinolaryngology, phoniatric, pulmonology outpatient clinics period February 2019 to January 2020. Results demonstrated that no statistically significant difference found three techniques (video-fluoroscopy, fiber-optic nasoendoscopy, drug-induced nasoendoscopy “DISE”) as regards shape collapse retropalatal, retroglossal, hypopharyngeal levels patient ( P : 0.621, 0.669, 1.0 respectively). Statistically, observed video-fluoroscopy, on one hand, DISE other regarding grade all 0.006, 0.037, 0.003). It mild favor DISE. Conclusion Video-fluoroscopy is good, reliable complementary preoperative tool identify patterns quantitative measurements.
