Morphometric study of vocal fold of different sexes of Bangladeshi cadaver.
The larynx is an organ of respiration and phonation. Larynx or Voice box is well developed in humans. The sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming etc. Pitch of the sound depends on the length, tension and mass of the vocal folds. This cross sectional descriptive type of study was done to see the length of the vocal folds and to establish the difference between sexes of adult Bangladeshi people. A total of 29 human larynges of adult age group ranging from 17 to 60 years in the both sexes were collected by purposive sampling during routine postmortem examination at the autopsy laboratory of Department of Forensic Medicine of Mymensingh Medical College, from October 2008 to March 2009. The mean length of vocal fold was measured and significance differences of the dimension between male and female were observed. In the present study observed finding was compared with those of other researchers. In male the mean(+/-SD) length of vocal fold was 23.12(+/-4.06) mm. In female the mean(+/-SD) length of vocal fold was 18.50(+/-2.39) mm. In statistical analysis, difference between male and female values was calculated by using Students (Unpaired) 't' test. The present study revealed that the value was greater in male than in female group and this difference was statistically significant (p<0.01).
