Cranial defects should be no stranger to people, the existence of many risk factors in life can cause cranial defects, and even now there are many children also appear cranial defects. Cranial defects in children can be congenital or caused by acquired factors, but regardless of the cause, the effects of cranial defects cannot be ignored. Some parents may wonder, they think that the child is in the stage of growth and development, so is it possible that the defective skull can slowly grow back and heal? Then is it not necessary to deal with it for the time being? Obviously, this is not true. Although there have been clinical cases where the defects have healed on their own, they are rare. Most children’s skull defects do not heal on their own, and they are very harmful, because the defects may collapse and deform over time, and some may affect the intracranial tissues, causing some physical discomfort to the child. At the same time, children are already more active, jumping up and down, if not accidentally bumped, it is even more dangerous. Therefore, children’s cranial defects must also be actively treated and dealt with, how to treat children’s cranial defects? At present, a more direct and effective way to deal with the problem of cranial defects is to do cranial repair surgery, which is a classic surgery in neurosurgery, with high surgical safety, so parents don’t need to worry too much. However, the choice of repair material can affect the success or failure of the surgery and the effect, and the surgeon’s technical experience is also very important, so parents should be careful in choosing. At present, many hospitals are using titanium mesh material to carry out surgery, which is a lot of progress than the early materials, but after clinical practice, titanium mesh material also still has certain problems, which is not the ideal choice.
