Abstract
Background: Out of different cartilages of larynx, cricoid is the strongest cartilage. It is the only cartilage which extends completely around the air passage. Renewed interest in subglottic stenosis recently has underscored the importance of detailed knowledge of cricoid cartilage. Aim: To study morphometric features of cricoid cartilage in adult human cadavers and also to compare the measurements of the cricoid cartilage between male and female. Materials & Methods: Larynx specimens of South Indian population, were collected from 62 cadavers (Male: 31, Female: 31) from postmortem bodies from the department of Forensic medicine, MMC and RI, Mysore for a period of 18 months from Nov 2013 to April 2015. Following four parameters like height of arch and lamina, outer Antero-Posterior and Transverse diameters were measured using digital vernier caliper in mm on each cricoid cartilage and the observations were tabulated. Results: Mean value of height arch of cricoid cartilage was 5.97±0.94 in male and 4.94±1.01 in female. Mean value of height of lamina was 21.3±1.9 in male, 17.91±2.29 in female. Mean value of outer antero-posterior (AP) diameter was 23.84±2.43 in males and 19.18±2.34 in female. The mean value of outer transverse diameter was 25.53±2.23 in male and19.29±2.52 in female. Conclusion: The mean values of all parameters of cricoid cartilage were more in males compared to females. The mean value of outer AP diameter was equal to the mean transverse diameters in females. Where as in males and the mean transverse diameter was more than AP diameter.
