If the skull is intact, the whole skull will look better, if the skull is defective, the image of the appearance will be greatly reduced. In addition, the skull also plays an important role in human health, it is like a helmet for the brain, once the skull is defective, the brain loses protection, then the intracranial tissues will be attacked by the outside world. Cranial defects should be taken seriously because they generally do not heal by themselves, especially if the defect area is large, it will also cause some discomfort to the patient, such as feeling dizzy and irritable, and the defect area will be deformed and collapsed after a long time, so remedial measures must be taken in time, that is, cranial repair surgery. Will the skull repair look the same as the original one? This should be the concern of every patient, in fact, the effect of skull repair is affected by many factors, such as whether the hospital and experts are professional, and more importantly, whether the repair material is good or not. Nowadays, many hospitals use titanium mesh material for skull repair surgery, which is still an improvement compared to the past titanium mesh material, but there are still some unavoidable problems. It is a new type of polymer material, which is very safe and its performance is almost equal to that of autologous skull, and it can be personalized and precisely shaped in three dimensions, which can better restore the skull shape of patients. In addition, we have introduced the concept of aesthetic plastic surgery, and the postoperative results are very natural and beautiful.
