Correction of Premature Closure of Sagittal Suture with Small-Incision Traction Bow

Premature closure of cranial suture is a disease in which skull suture fuses prematurely, which leads to deformity of skull, and then affects brain development and even endangers life. Premature closure of different cranial sutures can lead to different cranial deformities. Sagittal sutures usually begin to close about 18 months, and premature closure of sagittal sutures can lead to scaphoid head or long head deformities. Traditional surgery can only remove part of the skull after craniotomy, so as to increase the cranial cavity space and avoid restricting the growth and development of the brain. However, the operation is traumatic, and the sagittal sinus is located below the sagittal suture, which has a large amount of blood supply, and the risk of massive hemorrhage is very high. Therefore, through the simulation analysis of skull reconstruction in children, this study designed a minimally invasive incision, combined with the self-developed memory alloy traction arch, which avoided the destruction of sagitt.Through the application of binocular vision navigation system during operation, the position of traction arch before operation and the osteotomy line during operation can be accurately navigated to the operation field, which greatly improves the accuracy of operation and reduces the operation risk.
