We all know that titanium mesh is an excellent cranial repair and the success rate of the surgery is very high, but any surgery has a certain possibility of risks that we can not avoid so what are the possible risks of titanium mesh repair cranial surgery? And how to prevent it? 1, titanium mesh is a metal foreign body, implanted in the body may produce rejection and increase the chance of infection. 2, trimming the edge of the titanium mesh sharp easy to cut the skin; customized titanium mesh is too large and the overlap of the skull is too wide, local osteoporosis can lead to titanium nail loosening; if the titanium mesh poorly shaped can lead to the edge of the edge of the warping stabbing the skin. 3, the flap itself is thin or cutting too thin; flap internal surface hemostasis electric knife or electrocoagulation excessive cauterization; large bone flap decompression surgery after the cranial defect range is large, the need for the flap is also large, the more obvious the impact on the blood supply, local skin nutrition is poor, poor blood supply, the flap is prone to necrosis, ulceration, the incision cracking, the repair material is exposed. 4.The skin flap collapses obviously before cranial bone repair surgery, the skin flap incision is sutured with high tension, the incision edge is seriously damaged or improperly sutured, resulting in skin inversion, and the incision is difficult to heal. 5, two surgeries in the incision buried in the knot as a foreign body, such as the occurrence of knot reaction will cause infection, local itching after infection, scratching the trauma will gradually expand. 6, poor hemostasis of the skin flap during the operation or obvious collapse of the skin flap, large subcutaneous dead space or subcutaneous accumulation of fluid, blood, titanium mesh and the separation of the dura mater, leaving a residual cavity, resulting in difficulty in the healing of the incision. 7, Titanium mesh chronic cutting scalp. Intracranial low pressure on the scalp of the skull repair and the chronic cutting of the scalp by the fine titanium mesh net frame, so that the three-dimensional titanium mesh gradually become shallow, and finally lead to the titanium mesh exposed, which is a slow and gradual process. At the same time there is a more suitable material for cranial repair in the clinic. It can greatly reduce the risk of occurrence, that is, polyether ether ketone material, also called peek material, peek material is currently the most advanced material for the treatment of cranial defects. It is also one of the most suitable materials to be chosen for cranial repair surgery. Polyetheretherketone is a polymer material comparable to the body’s own cranial bone. It is much more biocompatible. It is strong but very elastic and resilient, more resistant to blows and better protection. It is also more comfortable. It has strong thermal insulation properties. There will be no sensitivity to hot or cold reactions. There will also be no infection after surgery and no rejection. Rays are transmissible and no artifacts are formed. A more important point is that polyether ether ketone is a material that can be three-dimensionally plasticized and can be customized for three-dimensional reconstruction according to the different needs of patients. Designed according to the patient’s brain CT data, 3D printing technology is utilized to create a skull that perfectly matches the bone window The repaired skull is basically indistinguishable from your own skull. The cure rate of the surgery is very high, but the skill and professionalism of the doctors engaged in peek cranial bone in China will also have higher requirements. Therefore, it is recommended to choose a more authoritative hospital if you need to undergo this treatment. These surgical risks do exist, but they do not necessarily occur. As doctors, we are obliged to warn patients of the possible risks of this surgery, and at the same time, we will do our best to ensure the safety of the surgery and improve the cure rate of the patients.
