Background: Morphometrical evaluation of the larynx has always been interesting for both morphologists and the physicians. A good understanding of the anatomy and the knowledge of variations in the laryngeal cartilages is important
Objective: Objective of the present study was to collect exact and reliable morphometric data of thyroid cartilage in adult human larynx of regional population.
Methods: The totals of 50 thyroid cartilage specimens were studied. The cartilages were preserved in 5% formalin. The measurements were taken with the help of Digital Vernier Caliper. The cartilages were weighed on Single pan electronic balance. For each of the parameters, the mean, standard deviation (S.D.) and range was calculated.
Results: Mean depth of superior thyroid notch was 9.7± 3.36 mm. Asymmetry between the length of superior horn of thyroid cartilages in left and right sides can be seen, but difference was not statistically significant (p>0.05). It is observed that inner thyroid angle varies from 55 to 1040 and outer thyroid angle varies from 53 to 990. In present study mean weight of thyroid cartilage was 6.70±1.55 grams.
Conclusions: A fair amount of intersubject variability in the dimensions was observed. Bilateral asymmetry, though present in majority of specimens, was insignificant. Various dimensions of thyroid cartilages are smaller as compared to the western population.
