% Irregularity is a coefficient computed by Speech Studio software at laryngographical (electroglottographic) examination of the larynx. The authors analysed values of % Irregularity obtained in 3 patients with vocal fold paresis. The patients were followed up for 6 months. Laryngography was performed 3 times in each of them at 3 months’ intervals. The value of % Irregularity was elevated in all patients immediately after the onset of complaints. It decreased after 3 and 6 months in the patient who regained the mobility of the paralysed vocal fold and in the patient with effective functional compensation by the healthy vocal fold. The value of % Irregularity did not normalize in the remaining patient whose vocal fold did not regain its mobility. The value of % Irregularity seems to correlate with perceptual degree of dysphonia.
