Dr Grace Ng Yang Huang

Dr Grace Ng is specialist in Maternal-Fetal Medicine, with expertise in fetal interventions and high-risk obstetric care. Her clinical focus encompasses fetal procedures, peripartum management, and specialized obstetric surgery. With a dedication to evidence-based practice, she provides comprehensive care throughout pregnancy, labor, and the postpartum period, with particular emphasis on managing complex antenatal complications.

As recipient of the HMDP fellowship at Mount Sinai Hospital, Toronto, Canada in 2024, Dr Ng gained extensive experience in advanced fetal interventions, including laser photocoagulation for twin-to-twin transfusion syndrome, intrauterine transfusions, and fetal myelomeningocele repair. Her commitment to advancing obstetric care is further demonstrated through her completion of a multicenter clinical trial investigating innovative labor induction techniques using cervical ripening balloon methods.
