RESUMEN
The aim of the study was to assess whether thetransverse diameter is directly proportional,and the anterior-posterior diameter inverselyproportional, to the angle of the thyroid cartilage,thus determining the degree of asymmetryin relation to age and sex, by comparingspecimens of larynxes. Analyses were performedon specimens of larynxes from cadavers: 50 male and 50 female. The age rangevaried from 40 to 98 years, with an average of58.68. Macroscopic analysis for the presence oflesions was performed with the aid of a magnifyingglass. A goniometer (Carci®) was used to obtain the angle of aperture of the two laminas of the thyroid cartilage. The internal dimensions of the cricoid cartilage were obtained using a digital pachymeter (Starrett®Tolls). The asymmetry index of the anteroposterior and transverse measurements of thecricoid cartilage was obtained for both sexgroups.The correlation between the angle of the thyroid cartilage and degree of asymmetry of the cricoid cartilage was insignificant in both males (r=0.027; p=0.426) and females (r=0.010; p=0.472). These findings suggest that there is no relationship between the angleof the thyroid cartilage and the degree of asymmetry of the cricoid cartilage. However, a significant difference was observed between the sexes in the transverse and antero-posterior diameters of the cricoid cartilage. Contrary to expectations, the findings failed to show the suggested relationship between the asymmetry index of the internal diameters of the cricoid cartilage and the external angle of the thyroid cartilage (AU)
