Cranial bone repair surgery is now a relatively routine and commonly used procedure in neurosurgery, because many cranial surgery procedures require the removal of bone flaps, and many traffic accidents, accidental injuries, etc. may also cause damage to the skull, so there are more and more patients with cranial bone defects at the present time, and then the cranial bone repair surgery needs to be carried out more often. Cranial bone repair surgery technology has been more mature, and the choice of what kind of repair material is very important. At present, the clinical application of the more advanced and ideal material to be counted on polyether ether ketone PEEK material, there are great advantages. Some patients also asked peek cranial bone repair material shortcomings there. A typical case of PEEK cranial bone repair A 11-year-old girl, due to cycling accidentally fell and caused a skull defect, and later in Beijing for cranial bone repair surgery, the use of polyether ether ketone PEEK material. The parents made a careful decision after inquiring and learning more about the material, in order to find a better repair material for their child. After the repair surgery, the little girl’s head was restored to its original appearance, and there were no adverse reactions after the surgery, which was a very good result. Like this use of PEEK material for cranial repair of patients there are many, many, from the clinical point of view has not found PEEK have any shortcomings. Advantages of PEEK material Compared with traditional common materials (such as titanium mesh materials commonly used in clinical practice), PEEK material has unparalleled advantages: good biocompatibility, will not produce a foreign body reaction; three-dimensional reconstruction, 3D printing, shaping the perfect; transmissible radiation, will not affect the postoperative CT MRI and other imaging examinations; embedded repair, in the bone window is completely attached to the articulation of the smooth, will not produce cuts and irritation injury; good insulation; good insulation, will not cause any adverse effects. Good thermal insulation, not too sensitive to external hot and cold environments; high hardness, can play a good protective role.
