Multidimensional measurements of pitch, intensity and mean flow rate, including the measurement of maximum phonation time, are common procedures used in evaluation of voice disorders. Using a RADAR-CHART of pitch, intensity and mean flow rate on easy phonation, we studied 103 voice disorder patients in whom routine phonetic function tests were completed preoperatively and postoperatively. These same patients were also examined using conditions of variable pitches and intensities. From this study, we concluded that construction of a RADAR-CHART composed of the above-mentioned three parameters during easy phonation, in addition to measurement of the parameter of mean flow rate under the special condition of maximum phonation time are indispensable methods for providing valuable information in the study of phonetic function in voice disorder patients.
