Clinical Evaluation of Respiratory Method and Phonation in Sinobronchial Syndrome

Experimental Use of Flownasalitygraph

Abstract

We used Flownasalitygraph SN-01 to evaluate the quantitative difference in respiratory method and phonation between patients with sinobronchial syndrome SBS and healthy adluts. Of the 15 SBS patients, mouth airflow was observed in 8, and mean value of the highest mouth airflow was 102.9 ml/s.
On phonating rhinolalia apert a such as a consonant “Na”, SBS showed higher nasal airflow ratio.
