A groundbreaking surgical technique developed by Professor Mashudu Tshifularo and his team at the University of Pretoria’s Faculty of Health Sciences may be a major advancement in treating conductive hearing loss—a condition affecting the middle ear, often caused by birth defects, infections, injuries, or metabolic disorders.

The procedure involves 3D-printing tiny middle ear bones—the hammer, anvil, and stirrup (ossicles)—and transplanting them to restore hearing. This innovative surgery has already helped two patients, including one who was born with an underdeveloped middle ear. The printed bones are made from biocompatible titanium and implanted using minimally invasive endoscopic techniques, reducing recovery time and scarring.

According to Prof Tshifularo, who heads UP’s Department of Otorhinolaryngology, this method is less risky than traditional prostheses and could be a game-changer for patients of all ages—even newborns. The surgery also minimizes the risk of damaging the facial nerve, a serious complication in standard middle ear surgeries like ossiculoplasty and stapedectomy.

Hearing loss affects many people as they age, and more than half of individuals over 80 experience significant hearing decline, according to the South African Hearing Institute. But with this new technique, there’s potential to treat a variety of cases safely and effectively.

Prof Tshifularo emphasizes the importance of medical innovation, stating, “Innovate or perish” is a motto he lives by. He calls on funders and sponsors to support this invention so it can reach more patients. For him, academic medicine isn’t just about theory—it’s about creating real-world solutions that serve communities in need.
