In a major medical breakthrough, a pair of toddler sisters born conjoined at the skull have been successfully separated following a complex, AI-assisted surgical procedure that has given them the chance to live independent lives.

Mercy and Goodness, from Ekiti State, Nigeria, were born in June 2023 with a rare condition known as craniopagus twinning, in which twins are fused at the top of the head.

Their case was particularly high-risk, as they shared both skull structure and critical brain tissue connected by intricate blood vessels.

At six months old, the girls were referred to Gemini Untwined, a British charity that specialises in separating conjoined twins.
