Variation of Antero-Posterior Diameter of Corpus Callosum in Different Age and Sex Groups of Bangladeshi People.

Abstract

The corpus callosum (CC), the largest commissure of the brain, connects the two cerebral hemispheres and lies at the bottom of the longitudinal fissure. The antero-posterior diameter of the CC was larger in males than in females, but this difference was not significant. Again, the length of CC increased with age and there was also a positive significant correlation between the antero-posterior diameters of the CC with the antero-posterior diameter of the brain. This cross sectional descriptive study was performed into four categories: Group A (20-29 years), Group B (30-39 years), Group C (40-49 years) and Group D (50 years and above). The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh Medical College, Bangladesh by purposive sampling technique Octy 2016 to Octy 2017. The antero-posterior diameter of CC was measured by using thread. The mean maximum antero-posterior diameter of corpus callosum was 8.25 cm in group D and minimum was 7.92 cm in Group A. When the diameter was compared between sexes in different age groups, it was significant in Group D and moderately significant in Group C. There was a positive correlation between antero-posterior diameter of corpus callosum and age of individual and it was statistically not significant. For statistical analysis, differences between age and sex groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the antero-posterior diameter of CC of Bangladeshi people and thus will minimize the dependency on foreign standards and also have diagnostic importance for the neurosurgeons and radiologists for clinical investigation and surgery.
