“Today, I received a phone call from a patient friend in Liaoning, he said doctor I did cranial repair surgery in our local hospital, with titanium mesh material, but I just repair less than a week, produced a rejection, there is no way that our doctors here can only give me to take it down, I’d like to ask like me to do the repair failed patients, but also can be done for a second time?” I would like to ask if a patient like me who has had a failed repair can have it done twice?” The following is an explanation of this question. Cranium shoulder protection “brain tissue” responsibility, once the skull due to external factors or diseases caused by defects, the loss of soft tissue protection of the brain, the brain is easily subject to external aggression, the patient’s health and life will pose a threat, this time we have to repair the defective parts, reshape the brain to protect the outer shell, once again, brain protection! The brain is protected again. Cranial defects, if not repaired to bring harm is very much, cranial defects after a long time without repair, patients may appear dizziness, headache, localized tenderness, irritability, restlessness and other manifestations. There are also some patients who appear to be afraid of the sun, afraid of vibration and even afraid of noisy sounds, often with poor self-control, poor concentration and memory loss. Or because of the atmospheric pressure directly through the defect area on the brain tissue, over time is bound to lead to local brain atrophy, aggravate the symptoms of brain damage. Therefore, after the cranial defect, if the condition of oneself allows, do the cranial bone repair surgery as soon as possible. Cranial repair surgery is a long history of medical technology, as early as thousands of years ago our ancestors have been carrying out such medical attempts, after thousands of years of development, technology continues to progress and mature, and now cranial repair surgery has been a more common and routine neurosurgery. However, there are still some situations that are less than ideal. For example, most hospitals now use titanium mesh as the repair material for cranial bone repair, a metal material that inevitably still has some problems. Titanium mesh material is covered in the bone window, the metal edge of the scalp may cause cutting headache; in addition, titanium this material is not ideal for human tissue compatibility, may cause rejection; and titanium mesh insulation performance is not good, the patient may be caused by postoperative sensitivity to heat and cold, and so on. Many patients with cranial defects have used titanium mesh as a repair material, but later on, the titanium mesh has been exposed and other complications. The patient has this question, can the skull repair surgery be done for a second time? Answer: Yes, it can be done a second time. For example, in the case of severe rejection and destruction of scalp tissue, the titanium mesh can be surgically removed and replaced with a better material for cranial bone repair about three months later. At present, hospitals commonly use advanced polyether ether ketone PEEK material for cranial bone repair, which has excellent performance and is comparable to the basic performance of human skull, and the PEEK material is three-dimensionally molded and accurately embedded in the bone window, which is very good at overcoming the above problems and achieving very ideal repair results.
