BACKGROUND
The Corpus Callosum (CC) can best be seen in the mid-sagittal section of brain both in cadaver and MRI. The morphometric measurements of the same will be of use in neurosurgical procedures. Sexual dimorphism and the age-related changes in its measurements remained controversial. Till date, no studies have been done on corpus callosum in Kerala.
MATERIALS AND METHODS
Measurements of CC has been taken and studied in detail in 24 formalin fixed brains from the Department of Anatomy and 48 MR images from the Department of Radiology. The changes according to age and sex were analysed.
RESULTS
The mean length of CC in the cadaver was 7.24 cm, which was 3.38 cm posterior to frontal pole and 5.73 cm anterior to occipital pole. In MR images, the mean length was 7.10 in males and 6.76 in females. The difference we got was not statistically significant. The length increased with age. Thickness of genu and body decreased as the age advances, but the splenial thickness was found to be increasing with age. There was significant correlation between the thicknesses of various parts of CC.
CONCLUSION
The values were almost similar to those in the previous studies. Morphometrically, a significant gender difference was not identified in the present study. There were changes according to age both in males and females.
