Recently, Taiwan's successful university Douliu Hospital used 3D printing to assist in the reconstruction of the tibia imaging technology, tailoring the 3D tibia model for patients, and assisting the success of oral cancer surgery, not only greatly reducing the time of surgery by 20%, but also reducing the burden on patients. Successfully reconstructed oral function.

Douliucheng Hospital recently completed the first computer-aided printing of the sacral bone cancer reconstruction operation in Yunlin, Taiwan. The patient was a 78-year-old man who was treated and tracked in other hospitals for oral cancer, and later relapsed due to oral cancer. Changed to the oral surgery of Douliucheng Hospital for medical treatment. After computerized tomography (CT) examination, the dentist Chen Mengyan decided to perform a humeral bone removal operation to completely remove the tumor. In order to completely repair the defected cheek, the 3D tibia model was tailored for him before surgery, which is the first in Yunlin. example.

Chen Mengyan said that the 3D printing-assisted patella reconstruction technique was developed by Wang Dongyu, director of the Oral Surgery Department of Chengda Hospital, and Fang Jingjing, a professor at the Institute of Mechanical Engineering of Chenggong University. Through computer-aided, the patient can tailor the shape of the tibia and reconstruct the patient. The integrity of the jaw to restore oral function and appearance has been adopted in the successful university general hospital for 10 years and promoted to many hospitals in Taiwan.

Chen Mengyan pointed out that in addition to the need to remove the tumor, oral cancer treatment sometimes requires placement of a titanium plate on the face to reconstruct the face. In the past, there was no 3D printed tibia model technique, the hand-made tibia model and the patient's original humerus often There is a drop, the doctor can make a repair of the titanium plate implanted in the defect cheek, it may not fully conform to the patient's face shape. After the reconstruction operation is completed, the flap will easily shrink and affect the patient's face. Now there is 3D printing technology, which can greatly reduce this. Class problem.

Dr. Chen Mengyan reorganized the sacral image using the technology developed by the successful university before surgery, and then customized the 3D tibia model for the patient. The titanium plate to be placed in the mouth was modeled using 3D printing technology. Oral surgery accurately removes the tumor, and then the reconstruction of the mandibular bone of the titanium plate. The plastic surgery then performs the reconstruction of the precise blood vessel and the free flap to repair the defected cheek, which not only shortens the operation time by 20%, but also successfully reconstructs the oral function.

Chen Mengyan said that the Yunlin area is the third highest incidence of oral cancer in men in Taiwan. The average age of death is 58 years old, and the age of cancer death is the smallest. Oral cancer patients are usually an important source of family economy, saving lives and restoring postoperative functions of daily life. The most important surgical goal.

The 78-year-old Agong is the first case in Yunlin County, Taiwan. The computer-assisted printing of the humerus is tailor-made for the shape of the tibia. Restoring the oral function and appearance is like having no knife. The old Agong is very satisfied with the operation.
