Congenital sensorineural hearing loss (CSHL) is a common disease in newborns, which can affect the development of corpus callosum (CC). In this study, a novel method of CC thickness analysis was employed to compare the CC difference between deaf and control groups. The results indicate that after 24 months deaf group has thinner CC thickness in the anterior splenium of CC compared to control group, which means the development of deaf anterior splenium is slowed down. Our study suggests that 12~24 month old is the best time period for CSHL treatment and intervention.
