PURPOSE: to evaluate the dimensions of vocal folds in both genders and correlate them with aging. METHOD: we studied 30 cadavers (15 men and 15 women) from 60 to 102 year-old. For this purpose we followed four steps: 1st) History of the body; 2nd) Removal of the larynx, 3rd) Dissection of the larynx, 4th) Morphometry for the dimensions of the vocal folds. This is an experimental study. RESULTS: the length of the vocal male with an average of 15.90 mm was higher than the female with 10.39 mm. The width of the male vocal was higher with an average of 2.37 mm to 2.31 mm with a female. The overall average thickness was also higher in males with an average of 2.55 mm compared with women with 2.38 mm. No differences were found among age and the length, width and thickness of the vocal folds in both genders. CONCLUSION: the dimensions of length, width and thickness of the vocal folds were higher in males. But, there was no statistically significant difference among the three dimensions of the vocal folds during aging in both genders.
