PURPOSE:
to verify the differences between the maximum phonation time /a/ and maximum phonation time predicted in relation to the respiratory type, and correlate the the maximum in adult women with vital capacity within the normal range and without laryngeal affections.
METHODS:
cross-sectional analytic research, quantitative and retrospective, in the database, 51 female subjects with an otorhinolaryngological diagnosis of absence of laryngeal affections, aged between 18 and 44 years (mean 27.64). It was used: higher value of maximum phonation time /a/, maximum phonation time predicted, vital capacity and respiratory type. The value of maximum time predicted for women, was calculated by multiplying the vital capacity by 0.0051, and the value found was decisive for the classification of phonation time /a/ in normal, below or above expectations.
RESULTS:
there were significant differences between maximum time predicted and respiratory type superior (17,44s) and mixed (15,17s). No significant difference phonation time /a/ in different and respiratory type, or correlation between phonation time /a/ and maximum time predicted.
CONCLUSION:
there was no correlation between phonation time /a/ and maximum time predicted and the maximum time predicted was significantly higher in respiratory type superior than in mixed.
