Accidental injury resulting in skull defects? The "brain-replenishing" material is better

" before we want to use PEEK materials to repair brain damage, can only be customized by foreign companies, the fastest more than a month patient's PEEK skull can come back, and now domestic enterprises have mastered this 3D printing technology, the fastest three days patients can get. On the morning of July 13th, the 3D printing and advanced cranial maxillofacial trauma repair-cum Tianfu Medical Exchange Summit Forum was held in Chengdu, Sichuan Province, and Professor Guan Junwen, Director of Neurosurgery at Huaxi Hospital of Sichuan University, introduced that the development of science and technology, the breakthrough of technical barriers to 3D printing, so that patients with brain injury benefit more.Accidental injury resulting in skull defects?" On June 13,2019
, a 6-year-old boy in Shenzhen, Guangdong Province, was hit by a glass window that suddenly fell on a residential building, causing acute severe brain damage, diffuse cerebral edema and other complications, and died.
"A lot of diseases we can overcome gradually, but no one knows if the next second will happen for accidental injuries." Professor Guan Junwen introduced that, with the increase of motor vehicles in China year by year, traffic accidents caused by brain injury is also more and more, data show that brain injury accounted for the second largest incidence of body trauma, but the rate of death and disability is occupied the first place. In addition to traffic accidents, intracranial hemorrhage, intracranial tumors, large-area cerebral infarction and other diseases such as cranial surgery can also lead to skull defects.
In the face of skull defects, "replenishing the brain" has become an inevitable choice for patients. "Without the protection of the skull, routine bumps can have serious consequences, especially poor child safety awareness, and if an accidental injury causes brain damage, if not repaired in time, parents will not be able to leave the child for a second." Zhang Wangming, deputy director of the Center for Neurosurgery at Pearl River Hospital of Southern Medical University, said that a large range of skull defects, patients due to atmospheric pressure to local scalp subsidence, may lead to intracranial pressure imbalance, brain tissue displacement and brain hemisphere blood flow reduction and cerebrospinal fluid circulation disorders, resulting in headache, dizziness, irritability, epilepsy, no other reason to explain discomfort and various mental disorders.Brain repair, PEEK material than titanium mesh better
want to live a normal life, to make up the missing skull is the only way for patients. At present, the usual repair material in China's clinical is titanium mesh, which has good bio-compatibility, better shaping effect, simple fixed operation, the incidence of postoperative complications is relatively low. However, titanium mesh as a metal conduction, thermal conductivity has also brought some patients trouble."There was a patient who was traveling after six months of titanium mesh repair, and in July it was hot, and the patient, wearing a hat, developed a headache dozens of minutes after moving in the sun, and the next day he developed skin burning sensations and blisters in the right forehead patch." Professor Guan Junwen pointed out that, on the other hand, titanium mesh as a metal, after repair patients in the future after the security check will cause alarm, in the conduct of radioactive examination is also prone to artifacts. Clinically, patients with thin skin are prone to the "titanium mesh imprinting" effect.
With the development of biomedical science, a new biomass polyether ketone (commonly known as PEEK) has brought a better experience to patients with brain repair.
As a synthetic polymeric material, PEEK was approved by the U.S. Food and Drug Administration in 2013 to be available as a bone transplant material. PeEK skulls are resistant to high temperatures compared to titanium mesh and remain property-resistant even at 260 degrees C. In addition, good tissue compatible, stable chemical properties, elastic modality and cortical bone similar, even if hit will not appear depression or deformation, can be very good to protect patients after cranial surgery. PEEK is high in strength, almost the same thickness as the skull, can accurately match the defect area, restore the original appearance of the skull, and do not need to be replastic in surgery, can shorten the operation time, reduce the risk of surgery.
"Previously we wanted to restore the patient's skull USPEEK material can only be customized from abroad, from the submission of applications to from the patient's PEEK skull, the fastest more than a month, and now the barriers to 3D technology has been broken, domestic companies like Mep Medical can do, patients want to get customized PEEK skull, the fastest 3 days can do." Professor Guan Junwen says peEK materials are now more expensive to use in applications than titanium mesh. Despite this, Professor Guan recommends that for patients with slow wound healing, children, severe complex injuries and allergic physiques, it is better to choose PEEK materials for repair and benefit more.
