Cranial repair surgery is a routine procedure in cerebral neurosurgery, and the techniques are well established, with clinical successes abounding. It is worthwhile for patients to consider the choice of repair material. The traditional titanium mesh material is prone to large postoperative hot and cold reactions, with external temperature stimulation, patients are experiencing chronic symptoms such as headaches, and postoperative infections are also relatively common. So much so that most patients will undergo a second surgery. The ideal material for cranial bone repair is PEEK, a newly developed polymer biomaterial that has been in clinical use for a shorter period of time than titanium mesh, but is many times more effective than titanium mesh. PEEK has the property of being highly adaptable to autogenous cranial bone, and doctors can use three-dimensional reconstruction technology to perfectly recreate the damaged bone window, with a size and shape that is unrecognizable from the previous site. The PEEK material, which highly reproduces the physiological structure of the skull, is very popular among patients because it is comparable to the autologous skull in terms of tissue descriptiveness, hardness, stability, and thermal insulation. The general cranial bone repair time is one hour to two hours. Warm tips: The above is the detailed introduction of how long it takes for cranial bone repair surgery, and I hope it will be helpful to you. It is recommended that patients go to regular hospitals as soon as possible to take appropriate treatment methods, active treatment, and early recovery of health.
