Abstract
Premature cranial suture closure is a disease in which a skull suture fuses prematurely, leading to a skull deformity that affects the brain development and even endangers the patient’s life. Premature closure of different cranial sutures can lead to different cranial deformities. Sagittal sutures usually begin to close at about 18 months, and premature closure of sagittal sutures can lead to scaphoid or long head deformities. Traditional surgical treatment involves removing part of the skull after a craniotomy, to increase the cranial cavity space and avoid restricting the brain’s growth and development. However, the operation is traumatic, and the sagittal sinus, which is located below the sagittal suture, has a large amount of blood supply, and the risk of massive hemorrhage is very high. Therefore, through a simulation analysis of skull reconstructions in children, we designed a minimally invasive incision combined with a self-developed memory alloy traction arch, which avoided destroying the sagittal sinus. Using a binocular vision navigation system, the preoperative position of the traction arch and the intraoperative osteotomy line can be accurately navigated in the operative field, which greatly improves the operational accuracy while reducing the risk.
