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.

The small saphenous vein (SSV) has several termination modalities and several types of afferent branches. The latter participate in the physiopathology of insufficiency of the small saphenous vein and explain the majority of recurrences after open or endovenous surgical cures. This study details the modes of termination and topography of afferents of the SSV. This is a cadaveric dissection involving 62 members of fresh and embalmed anatomical subjects. A popliteal approach and an extension is made towards the femoral region and towards the lateral malleolus are performed. Several parameters have been studied: the number of SSV, the number and distribution of terminal branches in the popliteal vein, in the great saphenous vein or in the thigh and the existence of musculocutaneous afferents of leg and thigh. We found that 45% of terminations were with a sapheno-popliteal junction. This form was absent in 55% of the cases. Consequently, the termination was either in the great saphenous vein, or in the posterior muscular compartment of the thigh, or in integumentary branches of the leg or thigh, or in the twin veins. This SSV received, in its course, twin veins, femoral veins, and integumentary veins.These anatomical variations of termination make a rigorous clinical and ultrasonographic examination indispensable in order to have a good mapping of the vein an to avoid recurrence of varicoses after surgery.
