Is it okay to leave a skull defect unrepaired? Cranial repairs need to be done, and cranial bones are generally not OK without repair. Why is cranial repair necessary? Is it okay to leave a skull defect unrepaired? The skull is one of the hardest bones in the human body, with considerable strength, and can provide strong protection for the brain and other head organs. However, there are still a few uncontrollable factors that can cause damage to the skull, such as trauma caused by falling objects, fights, traffic accidents, production safety accidents, etc., or having to remove part of the skull bone flap due to illness, which can lead to skull defects. If a defect occurs in the skull, you will be faced with cranial repair. Some patients ask, is it okay to leave the skull unrepaired? Usually it is not. With unstable intracranial pressure, all life activities in the skull may be disturbed, which may be manifested as headache, dizziness, in addition to the patient’s fear of throbbing, bulging and collapsing of the defect area, as well as fear of the sun, fear of vibration and even fear of loud noises. It may also cause inattention, memory loss, and some patients show depression, fatigue, reticence, as well as low self-esteem. So there is still a need for cranial repair. The repair material used in cranial repair surgery is very important. Director Zhu uses a new advanced material, Polyetheretherketone, or PEEK, for cranial bone repair, which can achieve ideal results. It is an ideal material for three-dimensional molding, precise matching, high biocompatibility, fewer complications, and does not interfere with medical examination. Neurosurgery experts said that PEEK material as the ideal material for cranial bone repair is because, PEEK material has very good tissue compatibility, basically will not produce a rejection reaction, PEEK material ray transmissibility is good, does not interfere with a variety of postoperative medical examination. In addition, PEEK material in the elasticity, strength, thermal insulation, stability and other aspects of performance are comparable to the human skull, is very ideal for cranial bone repair materials. Is it possible to repair a skull defect without repairing it? Through our introduction we understand that cranial defects without repair is not possible, so it is recommended that patients and friends go to regular hospitals to diagnose their own diseases and then choose the appropriate repair materials.
