Overview
- Nigerian craniopagus twins Mercy and Goodness were separated in Abu Dhabi by a team led by Professor Noor ul Owase Jeelani after a months-long, multi‑stage programme and have reportedly fully recovered and returned to Nigeria.
- Filipino twins Olivia and Gianna, joined at the chest and abdomen, underwent a six-stage separation at King Abdullah Specialist Children’s Hospital and were moved to intensive care in a stable condition following the final operation.
- Surgeons used detailed 3D imaging, virtual and augmented reality planning, AI modelling, ultrasound-guided tissue expansion and silicone scalp expanders along with an 'open book' technique to map shared blood vessels and reduce trauma during surgery.
- Both programmes relied on large multinational teams and institutional expertise from charities and hospital networks, though some claims about total operation counts and government funding were reported with limited sourcing.
- Because craniopagus and thoraco‑omphalopagus twins are extremely rare and high risk, these cases show surgical advances but also underline the need for specialized centres, long-term follow-up and support for the families involved.
