OBJECTIVES: 1) To compare nasendoscopy (NE) and multiview fluoroscopy (MVF) in assessing velopharyngeal gap size; and 2) to determine the relationship between these assessments and velopharyngeal insufficiency (VPI) severity. STUDY DESIGN AND SETTING: Retrospective review of consecutive patients with VPI at a tertiary care children's hospital, assessed with NE and MVF between 1996 and 2003. RESULTS: 177 subjects. NE and MVF gap areas were correlated (R = 0.34, 95% CI 0.26-0.41). In adjusted analysis, VPI severity was associated with: 1) NE gap area (OR = 2.78, 95% CI 1.96-3.95), 2) MVF gap area (OR 1.64, 95% CI 1.37-1.95), 3) age <5 years (OR 3.30, 95% CI 1.47-7.38), and 4) previously repaired cleft palate (OR 0.48, 95% CI 0.25-0.94). CONCLUSIONS AND SIGNIFICANCE: NE and MVF assessments provide complementary information and are correlated. Both are associated with VPI severity. However, the "bird's-eye view" provided by NE has a stronger correlation with VPI severity than MVF. EBM rating: B-2b
