Tumors op success using 3D technology
Print Edition
DOCTORS in southwest China’s Chongqing have successfully replaced a section of a cancer patient’s forehead with a 3D-printed part.
The patient, a woman in her early 20s, had recurrent tumors and kept her hair long at the front to cover the growths.
“I have had bangs for over a decade, finally I can grow my hair out and not be paranoid about my tumors,” she said.
When they first began to show, around 16 years ago, she had them removed but they grew back bigger than before. Despite multiple operations over the years, the tumors returned every time.
The tumors were eventually identified as benign, but due to their location they put pressure on her right eye socket, meaning if they were not removed they would likely impair her vision and limit her motor skills. Doctors agreed that a complete excision was the only suitable procedure.
However, due to the location of the tumors the operation would disfigure her face and the damage would be almost impossible to repair by traditional plastic surgery.
After discussion, a 3D-printed bone replica procedure was agreed as the best option.
The patient underwent a high-precision CT scan so that doctors could create a 3D reconstruction of her skull and print an exact replica of the bone part.
The piece was then implanted and fixed in place with titanium screws. The operation was a success and the patient was discharged from hospital a week after surgery.
