Background: The increasing application of sophisticated electro-physiological & radiological methods for the diagnosis and treatment of laryngeal disorders requires an extensive knowledge of the size and proportions of the human larynx & its cartilaginous components. Aims: To study the various morphometric measurements of the Thyroid & Cricoid cartilages in male & female in dissection & CT method and to compare the measurements of Thyroid & Cricoid cartilages between living (CT measurements) & Cadaver (dissected specimens). Materials and Methods: The present study was carried on 62 (31 Male, 31 Female) patients undergoing CT neck attending the Department of Radiology, K.R Hospital attached to Mysore Medical College & Research Institute, Mysore, Karnataka, India. In the Computerized Tomography of Neck, measurements of Thyroid & Cricoid cartilages were taken at two levels by using Radiant Dicom Viewer software. Thyroid and Cricoid cartilages from 62 cases (Male: 31, Female: 31) of postmortem in the department of Forensic medicine, MMC and RI, Mysore were studied. Various parameters on thyroid and cricoid were measured using vernier caliper. Results: The results by two methods showed significant differences after death i.e. by dissection method the AP measurements of both thyroid & cricoid cartilages are less compared to AP measurements of both cartilages by CT method in both sexes i.e. in living. Conclusion: We can conclude that there is decrease in AP distance of both thyroid & Cricoid cartilages in both the sexes after death. These morphological differences have important clinical and surgical implications. KEY WORDS: Larynx, Thyroid Cartilage, Cricoid Cartilage, Morphometry, Sex determination.
