PERICO, Maíra de Souza et al. Agreement between perceptual tests and videofluoroscopy in the diagnosis of velopharyngeal dysfunction. Audiol., Commun. Res. [online]. 2014, vol.19, n.3, pp.222-229. ISSN 2317-6431.  https://doi.org/10.1590/S2317-64312014000300004.

Purpose

To determine the agreement between the results of the Nasal Air Emission and Hypernasality tests and the videofluoroscopy findings in the diagnosis of velopharyngeal dysfunction in individuals with cleft lip and palate.

Methods

The sample consisted of 89 scores of Nasal Air Emission and Hypernasality tests and 89 judgments of videofluoroscopy recordings, which were interpreted as consistent velopharyngeal closure, or as inconsistent velopharyngeal closure, or as non velopharyngeal closure. The sensitivity, specificity and agreement between the interpretation of the results of the perceptual tests and the findings of the videofluoroscopy were calculated.

Results

The rates found for sensitivity of Nasal Air Emission and Hypernasality tests were 98% and 96%, respectively, and the rates for specificity of Nasal Air Emission and Hypernasality tests were 37% and 63%, respectively. Regarding the percentages of agreement between the Nasal Air Emission test scores and the videofluoroscopy judgments, it was found an agreement of 62% for the consistent velopharyngeal closure condition, 43% for the inconsistent velopharyngeal closure, and 68% for the non velopharyngeal closure. Between the scores of Hypernasality test and videofluoroscopy judgments the agreement found was 70% for the consistent velopharyngeal closure condition, 47% for the inconsistent velopharyngeal closure and 77% for the non velopharyngeal closure.

Conclusion

There was a good level of agreement between the perceptual tests and the videofluoroscopy judgments for the consistent velopharyngeal closure and non velopharyngeal closure conditions, but not for the inconsistent velopharyngeal closure.
