[Sexual dimorphism of morphometric parameters of arytenoid cartilages as a criterion for establishing human sex].

The objective of the study is to determine sexual dimorphism of morphometric features of adult arytenoid cartilages (AC) as applied to forensic medical examination of personality identification. The SC of 254 males and 106 females who died of mechanical strangulation asphyxia between the ages of 19 and 91 years were studied using the set of 14 parameters. All the parameters have a normal distribution according to Pearson's χ2 test. Their means were significantly higher in men than in women. Sex differences in the coefficients of variation of the parameters are insignificant. All AC parameters correlate closely with sex (r=0.775-0.830), but there is almost no correlation with age and body length. The same dimensions of the right and left AC have a high correlation (r=0.8-0.9) and are subject to separate analysis. The morphometric parameters of AC are highly informative and present a valuable option for a forensic determination of the sex of an adult human.
