In South Africa: first transplants of middle-ear bones made using 3D technology



On Thursday, a South African medical team announced that it had fitted "transplants of small middle-ear bones [1] made using 3D printing". This is reportedly "a world first". The latest operation was performed on Wednesday at Steve Biko Hospital in Pretoria. It involved a "35-year-old patient whose inner ear had been completely damaged in a car accident".

 

This operation "may be the answer to conductive hearing loss, a middle-ear problem caused by congenital birth defects, infection, trauma or metabolic diseases," including in newborns, explained the University of Pretoria. "By replacing only the ossicles that aren't functioning properly, the procedure carries significantly less risk than known prostheses," said Professor Mashudu Tshifularo, who has supervised three of these transplants.
