anatomical titanium mesh-3D cloud shape

Preformed mesh is an anatomic, ready-to-use solution for the reconstruction of cranial defects. Off-the-shelf, ready-to-use sterile implants; anatomic shapes based on scientific study and clinic data; contoured to reduce bending & procedure time; economic solution with aesthetic results. Preformed Mesh is intended for use in fixation of the cranial bones in procedures such as reconstruction, fracture repair, craniotomies and osteotomies.

Timing of operation: 3 months after the skull defect, the pressure at the skull defect site is not high, and there are no factors that are not conducive to the healing of the incision, such as infection and ulcer.

Preoperative preparation: All patients had no contraindication to surgery, and all underwent cranial CT and frontal X-ray examination.In the digital molding group, thin-slice CT scan was routinely performed with a thickness of 2mm, and three-dimensional reconstruction of the frontal bone was performed. Then, the two-dimensional titanium mesh was molded by "titanium mesh digital molding machine", and the two-dimensional personalized titanium mesh repair was completely consistent with the patient's frontal bone defect, which was sterilized for later use.In the 3D easy plastic molding group, a 3D easy plastic titanium mesh more than 2cm larger than the defect edge was selected, which was premolded with a traditional mold and sterilized for later use.All patients underwent general anesthesia with endotracheal intubation and overlay repair.According to the size and shape of the frontal bone defect of the patients, the three-dimensional easy-to-plastic group cut the titanium mesh, manually molded the mesh as far as possible to meet the requirements of the patient's defect site, polished the edge and put it at the bone window, and fixed it with a matching self-tapping titanium nail.Routine use of antibiotics to prevent infection, 1 ~ 2 days to remove the drainage tube, 10 ~ 12 days to remove stitches.The wound healing, plastic effect and complications of the patients were observed for a short period of time after surgery. The efficacy was finally evaluated according to the following criteria in the follow-up 3 months later. Excellent: reliable fixation of titanium alloy mesh plate, beautiful appearance, no postoperative complications; Good: Titanium alloy mesh plate fixed reliably, postoperative complications improved after symptomatic treatment; Rejected: titanium mesh slippage and displacement, or removal of titanium mesh due to other surgical complications.

Data copy 3D CT as far as possible to use 1-2 mm scanning, high precision data to make the statue more accurate.To copy data, it is necessary to copy the original DICOM data in the CT room to save data processing time.Try not to copy the image data in the workstation, which will make the process more complicated and less accurate.Causes time delay or molds can not be used.

Children skull repair matters needing attention: 1. Try to listen to the doctor's advice by two statues because children's skull is in the stage of development skull gyrus growing changes.Because the titanium mesh is a metal that will not grow, it will cause the asymmetry of the skull, which will affect the appearance and the development of the brain.2. Try to use three-dimensional titanium mesh, because three-dimensional titanium mesh is softer and has a certain expansibility. However, we should pay attention to let children not do too strenuous exercise as far as possible.
