Gender differences in the normative dimensions of internal organs of 17-years teenagers with differentsomatotypic characteristics

Abstract

Individualization of approaches in preventive and clinical medicine requires individualization of normative indexes for the protocols in measurement of dimensions of internal organs. At the same time the constitutional principle for the establishment of personal protocols for supersonic morphometry of liver, gall bladder, spleen, pancreatic and thyroid glands are discussed. At the same time the age quantitative age and gender group differences remain unsufficiently studied. The purpose of the study was the investigation of specific constitutionally-dependent differences in the size of internal organs in concern with their possible somatotypic correlates. 49 female and 52 male 17-years old teenagers were studied during regular prophylactic medical inquiry using somatotypic identification and supersonic morphometry of the pancreatic and thyroid glands, liver, gall bladder, spleen, lenic and portal veins. The study revealed statistically significant larger size of liver and gall bladder in leptosomic and mesosomic males in comparison to the females of corresponding somatic types. In addition, mesososomic males possessed increased lumens of splenic and portal veins together with increased dimensions of pancreas and spleen. The reported data s can be used in clinical practice for prevention of erroneous conclusions about hyper- or hypertrophy of internal organs. The results of the study give opportunities for the establishment of anatomical standards of morphometric measurement of internal organs in concern with constitutional characteristics. The revealed somatotypic correlations can serve as markers of individual morphometric characteristics of internal organs.
