To remove or strip away the pericranium (the membrane covering the skull).
From the prefix dis-, Greek peri- (around), and kranion (skull), plus the suffix -ate. This is a highly specialized anatomical or surgical term from medical terminology.
This surgical term appears in 18th-century medical texts where surgeons had to describe skull operations—it's a perfect example of how medical professionals use Latin and Greek like a specialized jargon to describe precise procedures.
