At the end of April last year, a boy in Taichung City was injured by riding a bicycle, resulting in serious head injuries. After the rescue, he miraculously recovered and was discharged smoothly. However, the left skull was broken into 13 pieces, and the skull healed badly after discharge, which might affect the nerve function by puncturing the scalp. Lin Zhilong, director of neurosurgery at the Affiliated Hospital of Asian University, said that when the boy arrived at the hospital, his skull was badly broken and he opened it for debridement. Three months later, he had another skull plastic surgery to restore the skull temporarily placed in the abdomen, and finally recovered his life.
The skull reconstructed by 3D printing looks like a normal person.
Lin Zhilong pointed out that the fracture of the boy's lateral skull was too serious to be completely closed and recovered, which made the head shape on both sides asymmetrical. One of the skulls almost pierced the scalp for fear of infection. The skull was reconstructed by 3D printing to replace the defect area. The operation was successful and the appearance was almost the same as that of normal people.
Autologous bone fragments in cranioplasty easily increase the risk of infection.
Lin Zhilong explained that there are many kinds of repair materials used in cranioplasty, which can be divided into autologous tissue and allogenic material. Considering that the use of autologous tissue has few complications and does not require additional material costs, most people will choose to put the skull of the injured person into the abdomen or bone bank first. For future repair; However, due to poor healing and absorption of autogenous bone fragments, it is easy to loosen and sag the brain downward, or make the skull protrude upward and pierce the scalp, which increases the risk of infection, and the appearance is not beautiful, which may affect the self-confidence in the future.
Titanium alloy skull repair surgery has high aesthetics and low risk of complications.
After evaluation, Lin Zhilong decided to adopt "titanium alloy skull repair surgery" and use titanium alloy omentum as repair material. Because the titanium alloy omentum has the advantages of firm material, low tissue reactivity and close to the elastic coefficient of skull, the titanium alloy omentum is used for skull reconstruction by using preoperative brain tomography data and 3D printing technology. After operation, the skull is symmetrical left and right, covering the atrophic temporal muscle, shortening the operation time, reducing the risk of complications and restoring the confidence and beauty of boys after operation.
