Taipei hospital uses 3D printing for jaw reconstruction surgery

台北醫院使用 3D 列印進行下顎骨重建手術

TAIPEI (Taiwan News) — Taipei Veterans General Hospital has adopted 3D printing technology in jaw reconstruction surgery, helping a man surnamed Lin (林) rebuild his lower jaw using bone from his lower leg.

The hospital detailed Lin’s case at a press conference held on Wednesday. Wu Cheng-hsien (吳政憲), head of the Department of Oral and Maxillofacial Surgery at the hospital, explained that Lin had oral cancer, which had spread to his lower jaw, upper jaw, and surrounding soft tissue, resulting in significant tissue loss, per CNA.

The medical team used computer-aided design and virtual surgical simulation to plan the procedure. During the surgery, a navigation system was used to improve the precision of the tumor removal and facial reconstruction.

The team then utilized 3D printing technology to create custom implants tailored to Lin's facial structure. They also removed a section of Lin’s lower leg bone, reshaped it into a U-shape, and connected it to an artificial joint.

Wu noted that the limitations of typical reconstruction techniques may result in an unnatural appearance after surgery, which affects quality of life. Such outcomes could also impact the feasibility of future dental implants.

Wu emphasized that, compared to previous reconstruction techniques, Lin's facial symmetry and bite alignment were significantly improved. Lin added that his mobility also improved considerably three months after the surgery.

According to the hospital, such an operation is highly complex and requires careful evaluation of the cancer’s extent, the patient’s age, and the potential risk of post-surgical infections or complications before determining if the procedure is feasible. The team spent more than a month planning Lin’s surgery.
