Abstract

Background: The cricothyroid joint is an important anatomical structure of the larynx and its morphometric variation with age and sex has clinical relevance.

Methods: A descriptive cross-sectional study was carried out to evaluate the distance between the cricothyroid joints relative to age and gender in cadaveric samples from Bangladesh. Sixty human larynges were collected postmortem over six months — forty-five from autopsied individuals aged 9 to 60 years, and fifteen from stillborn fetuses (gestational age 28–40 weeks). Distance was measured in millimeters using slide calipers.

Results: The mean distance between the cricothyroid joints was 9.40 mm in the fetal group, 20.44 mm in the pediatric group, and 24.07 mm in the adult group. The differences among all age groups were statistically highly significant.

Conclusion: The distance between the cricothyroid joints increases progressively with age, showing significant variation among fetal, pediatric, and adult larynges.
