Skull fracture has many symptoms, but most people may not know about it, many people will have dizziness and headache, scalp hematoma, hemiplegia and aphasia, and there will also be bleeding symptoms, if the situation is more serious, it will fall into a coma, and may face death at any time. In ordinary life, skull fracture chances are relatively small, this is mainly because of direct violence caused by an abnormal phenomenon, but after the skull fracture, because there are some symptoms may be relatively mild, which will be ignored, the later will cause serious complications, and even threaten the life, so what are the clinical symptoms of skull fracture? The clinical manifestations of skull base fracture will be different according to the different parts of the fracture. In the case of fracture of the anterior skull base, patients often have the typical panda-eye sign, and may also suffer from loss of smell, varying degrees of visual impairment or even blindness. Cerebrospinal fluid nasal leakage, cerebrospinal fluid ear leakage and carotid cavernous sinus fistula can occur, and cranial nerve injury causes numbness of the face, eye movement disorders and a series of other conditions. Fractures of the base of the anterior cranial fossa can also cause cerebrospinal fluid leakage, while cerebrospinal fluid ear leakage does not usually occur. With posterior cranial fossa base fractures, there is a classic sign of delayed petechiae in the mastoid region. Fractures of the posterior cranial fossa can also occur with cerebrospinal fluid ear leakage as well as hoarseness and choking on drinking water that occurs with cranial nerve injury. What should be used to protect the brain from a severe skull fracture causing a defect? After the skull is missing, it is necessary to carry out cranial bone repair surgery in time, that is, using certain artificial materials, to repair the area of the missing skull, and to protect the brain tissue and organs of the head and face again, which is of great significance to the human health and the operation of the whole organism’s life. Cranial bone repair surgery is a routine procedure in neurosurgery, and the technology has been very mature. Polyether ether ketone peek material is a new type of special polymer material, its various properties are very close to the human autologous skull, used for skull repair, the effect is very ideal, implanted in the human body after the protection performance is strong, high degree of comfort. peek material hardness is very strong, you can play a very good role in protection; peek material insulation is good, will not due to the outside world’s heat and cold and sensitive to discomfort; peek material Will not interfere with all kinds of radiation and magnetic field, does not affect the patient to accept ct magnetic examination after surgery; peek material tissue compatibility is very good, basically will not occur after the operation of infection and rejection, etc.; peek material can be personalized according to the shape of the patient’s bone window of the three-dimensional plastic design, highly restore the structure of the skull; peek material is embedded in the repair, repair the edge of the bone window is smooth and articulated, will not The peek material is embedded, the edges of the bone window are smoothly articulated after the repair, which will not cause abrasion to the scalp, and the appearance is more beautiful.
