PURPOSE: to compare the electroglottographical evaluation results in women with otorhinolaryngological reports of vocal nodules and presence of glottal gap and in women with no larynx alteration. METHOD: 20 women took part in this study, 10 with otorhinolaryngological exam of vocal nodule, associated with glottal gap, and 10 with voices evaluated in the perceptive-audio analysis as neutral and electroglottographic evaluation without larynx alteration. The age group varied from 27 to 55 year old, with average of 37.60 for the study group and 36.00 for the control group. The voice material was the habitual emissions of the sustained vowel /a/. We extracted the measures of quotient of contact, fundamental frequency, jitter, as well as the sorting and interpretation of the kinds of waves and presence of electroglottographic knee. The statistical analysis has been accomplished by the Fisher Exact test and T of Student. RESULTS: all traces were sorted as Type II (100%). The difference in the presence or absence of knees between groups was not observed. The average of quotient of contact was 42.52 for the study group, and 45.56 for the control group. In spite of the minor value for the studied group, there has been no significant difference between groups for the fundamental frequency and jitter. The average of the fundamental frequency was 193.18 and 211.69 and, the average value of jitter was1.21 and 2.9 for the study and control group, respectively. CONCLUSION: women with mass lesion in the vocal folds show higher jitter values and minor values as for the electroglottographic fundamental frequency.
