Pioneering AI Enables Landmark Twin Separation
21 Jun
Summary
- Conjoined twins were separated using groundbreaking artificial intelligence techniques.
- Over 60 healthcare professionals from four countries collaborated on the surgery.
- The twins, Mercy and Goodness, have recovered and returned to Nigeria.

Twin sisters Mercy and Goodness, born conjoined at the head in Nigeria's Ekiti State, have undergone a groundbreaking separation surgery utilizing advanced artificial intelligence. The complex procedure, involving a multidisciplinary team of over 60 healthcare professionals from the UAE, UK, Nigeria, and Brazil, marked a significant advancement in surgical techniques for craniopagus twins.
The twins, who were six months old when referred to Gemini Untwined, underwent multiple surgeries in Abu Dhabi over four months. The separation occurred when they were 19 months old. This rare procedure, one of only nine craniopagus twin separations globally, required over 40 hours of operating time.
Innovations included detailed AI-driven brain imaging for surgical rehearsal in mixed reality, an "Open Book" approach to minimize brain pressure, and AI-assisted insertion of skin expanders to avoid grafts. These techniques are contributing to safer, more effective pediatric surgeries and better outcomes for conjoined twins.
Mercy and Goodness have since made a full recovery and have returned to their home country of Nigeria. Their successful separation offers a new future for the twins, allowing them to experience life as distinct individuals.
