Accidental fall, 9-year-old child with skull damage Every parent wants their children to grow up healthy and happy, but as the saying goes, “the sky is unpredictable, and people have their own luck”, accidents in life are always unavoidable. Tong Tong (a pseudonym) is one such child who met with misfortune. A year and a half ago, the 9-year-old fell from the fifth floor, resulting in a crushed skull fracture, brain hemorrhage and concussion, and doctors had to remove the bone flaps on both sides of her parietal lobe to decompress and remove the hematoma. It should be said that it was a miracle that she survived. However, the two huge defects (10x12cm on the left side and 7x8cm on the right side) left behind after the removal of the bone flaps put the doctors in a dilemma – the traditional repair materials cannot adapt to the skull growth of children, and repair materials like metal titanium mesh also absorb external heat, often resulting in skull deformity and brain tissue development Restricted. If the skull is not repaired, the tender brain tissue will be easily damaged again, and the long-term cranial defect will also lead to impaired cognitive function, poor limb function, strabismus, facial palsy, dizziness, ataxia and other symptoms, which is called “decompression window syndrome” in medical science. Due to the difficulty in repairing the cranial defect, the family spent more than $700,000 on surgery and rehabilitation, but the child’s cognitive function is still deteriorating and the shrinkage of brain tissue in the defective area is getting more and more serious. The search for a new material that can symbiotically work with the skull and repair the cranial defects early without limiting the growth of the child’s brain has found the ideal material! Left: Artificial bone structure Right: Natural bone structure Careful implantation, perfect repair With such a satisfactory repair material, the professor proceeded to the clinical validation of its use. For more than a year, the professor modified the formulation of the bionic bone through extensive research in order to more closely match the shape and hardness of the flat skull, and obtained satisfactory results. For Tong Tong’s condition, the professor first obtained comprehensive cranial defect data using CT scans, generated a defect model using software transformation, and then used 3D printing technology to customize a prosthesis to fit Tong Tong. During the surgery, the prosthesis was slightly modified according to the actual defect, carefully implanted and fixed. After the surgery, the child’s cognitive function improved rapidly and the results were immediate. When reviewed six months after the surgery, the bone density of the repair site had been perfectly aligned with the autologous cranial bone, indicating that the autologous bone had successfully replaced the artificial bone and achieved a perfect repair. Before and after surgery When the cranial defect of children meets the bionic artificial bone, the dilemma finally gets a perfect solution!
