Growth of the human prepubertal and pubertal larynx.
Prepubertal, pubertal, and adult measurements of human larynges were used to describe growth of the larynx from prepuberty to adulthood. Linear and weight measurements made of 10 Caucasian male and 10 Caucasian female prepubertal and pubertal cadaveric larynges were compared to adult measurement data obtained from another study on 20 male and 20 female larynges of adults, aged 37-70. In both studies measurements and experimental protocols were similar, allowing direct comparisons to be made between samples. Results highlight specific quantitative characteristics and trends in circumpubertal growth of the laryngeal cartilages and the vocal folds for each sex and with respect to sex differences. The results are discussed with respect to the literature on postnatal laryngeal development and to published research on adolescent voice change.
