Same Noses, Different Nasalance Scores: Data from Normal Subjects and Cleft Palate Speakers for Three Systems for Nasalance Analysis

Nasalance scores from the Nasometer, the NasalView and the OroNasal System were compared. The data was collected from 50 normal participants and 19 hypernasal patients with cleft palate. The Nasometer had the lowest nasalance scores for the non-nasal Zoo Passage and that the OroNasal System had the lowest nasalance scores for the Nasal Sentences. The nasalance distance was largest for the Nasometer and smallest for the OroNasal System. When the calculation was based on nasalance magnitudes, results for sensitivity ranged from 57.9% to 81.8% and results for specificity ranged from 62.0% to 76.0%. When the calculation was based on nasalance distances, results for sensitivity ranged from 84.2% to 100.0% and results for specificity ranged from 82.0% to 100.0%. Results suggest that nasalance scores from the three systems are not interchangeable. Diagnostic efficacy improved when the calculations were based on nasalance distances rather than magnitudes, but further research is warranted to corroborate these findings.
