[Expert consensus on skull defect reconstruction after decompressive craniectomy in children (2025 edition)].

Children with skull defects after decompressive craniectomy face issues such as lack of brain protection and aesthetics during the recovery period, which also affect the recovery of brain structure and function and hinder subsequent rehabilitation. The skull of pediatric patients is still in the growth and development stage, with head circumference changing with age, and there are characteristics such as easy bone hyperplasia and absorption. Therefore, the timing, materials, methods and other problems of skull reconstruction for pediatric patients have always been puzzling clinical practice. The Chinese Congress of Neurological Surgeons of Chinese Medical Doctor Association, the Chinese International Association of Pediatric Neurosurgeons, and the Expert Consensus Collaboration Group on Skull Defect Reconstruction after Decompression Craniectomy for Children jointly organized relevant domestic experts to adopt the Delphi method and combine literature analysis and expert experience to form a total of 27 recommendations on the necessity, timing, materials, surgical precautions, complications and other aspects of reconstruction, hoping to provide important reference for skull defect reconstruction surgery after decompression craniectomy for children.
