Abstract
Introduction: Out of different cartilages of larynx, cricoid is the strongest cartilage. It is the only cartilage
which extends completely around the air passage. It is smaller but stronger and thicker than the thyroid
cartilage. Though a lot of work has been done on thyroid cartilage it is not so for cricoid cartilage. This give us
a impetus to design this study.
Material and method: The material for present study comprised of 30 adult (M:F::25:5) apparently normal
cadaveric larynges, obtained from the Anatomy Department of Govt. Medical College, Amritsar. Different
morphometric diameters of the cricoid cartilage were measured with help of vernier caliper with least count
0.01mmand thesewere noted on a predesigned proforma. All the data thus obtained was tabulated, analysed,
scrutinized and compared with the earlier studies available in the literature. An attempt has been done to
provide a base line data for this region.
Result and Conclusion: Cricoid cartilage was oval in shape in all the specimens. Outer and inner transverse
diameters and outer and inner anteroposterior diameters of cricoid cartilagewere larger in males as compared
to females. As we compare both diameters in males and females, outer transverse diameter was found to be
larger than outer anteroposterior diameter, while inner anteroposterior diameter was larger than inner
transverse diameter. Height and thickness of cricoid arch and lamina were observed to be larger in males as
compared to females.
