OBJECTIVE: To determine relationship between screening perceptual assessment for resonance disorders and nasalance scores. MATERIAL AND METHOD: Screening perceptual assessment of 115 children with cleft palate with or without lip was performed to determine its relationship to nasalance sores. The perceptual assessment 3-scale (-1: hyponasality; 0: normal; +1: hypernasality) was compared to nasalance scores based on nasometry. To find the weight of Kappa, nasalance scores were converted to a 3-ordinal scale with 3 criteria for cut-off points (-1: nasalance score -1, -1.5 and-2 SD lower than the mean, 0: nasalance score +/- 1 SD, +/- 1.5 and +/- 2 SD of the mean; and + 1: nasalance score + 1 SD, + 1.5, and + 2 SD greater that the mean). RESULTS: Correlations between screening perceptual assessment and nasalance scores were good to excellent. The percentage of agreement was good, the Kappa reliability was fair to moderate in passages of a mixture of oral and nasal consonants (My House) and devoid of nasal consonants (Laying Hen). A weak relationship was found for the nasal passage (Winter). CONCLUSION: The relationship of speech assessments in the present study varied, as it depended on the different variables and analysis. To ensure a strong relationship, further prospective study is needed.
