Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): The bones above the temples on both sides of the head were removed by more than 100 square centimeters due to a car accident] Hello: My daughter is 17 years old, and two years ago, the bones above the temples and ears on both sides of the head were removed by more than 100 square centimeters due to a car accident (about 50 or 60 square centimeters each). At that time, the cranium was opened twice because of the need for resuscitation, and the interval was more than 30 hours. Now, more than two years have passed, and in October this year, I am going to make up for the bone, will there be sequelae after the bone repair? What should I pay attention to before and after the bone repair? Thank you! Now I am recovering well, but when it rains, my head hurts a little, but normally it does not. There is a boy in our village who is 25 years old and had his head bones taken out in a car accident four years ago. Last year, he had a cranial repair operation with titanium plates in a major city hospital. Later, I went to the hospital and had the titanium plate removed, so I didn’t feel any pain or swelling. After a while, I went back for cranial repair, and soon after I was discharged from the hospital, I had swelling and pain at the cranial repair site again. This is how the cranial repair surgery was repeatedly done three times, and the money was spent more than 100,000 not to mention the fact that now a person’s head is opened up beyond recognition. I am now the main is to consult this problem? Doctor: In principle, skull defects larger than 3~5cm need to be repaired surgically, the purpose is to prevent epilepsy or severe pain and low cranial pressure caused by skull defects. Generally, surgery should be performed 3~6 months after the last surgery, which can significantly improve the patient’s quality of life. Surgery has three purposes: 1) to protect the brain; 2) to reduce complications such as epilepsy; and 3) to improve the appearance. There are various materials used, which need to be decided on a case-by-case basis. Complications are rare, but if a local infection occurs, the repair material will need to be removed again. There are very few patients who have a strange sensation after the skull repair, but no problems are found on examination, which may be related to psychological factors.
