temporal fossa interlink plate

Because it is the repair of skull tissue, the selection of materials first requires high biocompatibility, and the need to ensure a certain strength and stiffness at the same time, which not only provides strong enough protection, but also meets the needs of intraoperative shaping, so as to achieve a satisfactory effect of contour repair and plastic surgery.The repair materials include autologous cranial flap repair, metal prefabricated repair, three-dimensional titanium plate and CT three-dimensional repair.If craniotomy is needed for any reason, the skull flap can not be reimplanted in situ immediately after incision, but can be buried under the autologous skin for preservation and retention.In the autologous skull group, although the complications were few and the repair shape was satisfactory, the patient's pain would be increased due to the need for a second operation, and the skull had the disadvantages of smaller absorption or even necrosis, loosening after repair and unstable fixation.If the operation of preserving the autogenous skull can be simplified, the environmental requirements of preserving the autogenous skull can be reduced, and the autogenous skull can not be deformed, the use of autogenous skull replantation will be the best skull repair.Fortunately, now with the cranium. cryopreservation technology, the patient's autologous bone flap can be preserved intact for a period of several years. When the patient needs postoperative repair, the autologous bone flap can be installed back to the patient's defect site at any time to achieve the perfect state.Titanium mesh is the most commonly used material in the repair of metal prefabricated products.As people living standard rise, people should not only through the skull repairing recovery can reach anatomical, physiological, is becoming more and more high to the requirement of appearance beauty, in order to repair the body and the patients with skull chimeric more perfect, always reconstructive surgery is generally by the doctors in preoperative or intraoperative according to patients with the size and shape of the defect parts, hand type titanium alloy sheet, after comparing patients with head repeatedly repair type, cut seam, until meet the requirements of the patients with defect parts with screws, finally this requires that the doctor must according to the shape of the patients with skull defect on the operating table to produce restoration as soon as possible,However, due to the different shape of the skull defect in each patient, the repair material titanium alloy is not easy to shape, and repeated molding is required during the operation, which increases the operation time. Moreover, repeated cutting of titanium alloy mesh plate will weaken its strength, increase the usage of titanium alloy screws, and then increase the operation cost.Three-dimensional appearance of titanium plate makes it easier to shape change, but the hardness is better than 2 d titanium plate, and adopted the digital skull shape technology, this part of the work can be very good to complete before surgery, greatly shorten the operation time and wound also less exposure time, greatly reduce effusion and infection occurred after the opportunity, at the same time reduce the labor intensity of surgery doctor.CT 3D reconstruction technology of digital skull shape technology is a revolutionary progress of bone repair surgery, CT three-dimensional reconstruction is based on the status of the patients with skull defect, simulate the natural forms of the skull, after CT data processing, 3D reconstruction of medicine, the surface of the skull of natural surface mapping, computer aided design of graphics and titanium digital manufacture and so on five procedures, using three-dimensional CT examination results, for patients with precise design of the personalized repair defect of skull, titanium alloy during surgery successfully fixed on the head of the patients with defect, the technology to realize the precise combination of the titanium alloy with skull defect parts,To achieve effective mechanical protection of brain tissue, achieve good therapeutic effect, but also reduce the pain of patients, treatment risk is also greatly reduced, postoperative recovery period of patients is shortened, can quickly recover to work, integrate into the society.
