Abstract
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. Themeasurementswere takenwith the help of Digital Vernier Caliper. The cartilages wereweighed 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 from55 to 1040and outer thyroid angle varies from53 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.
