METHOD FOR SUBPERIOSTEAL FRAGMENTATION OF PARIETAL BONES WITH OSTEOTOMY IN PROJECTION OF SAGITTAL SUTURE IN ISOLATED SAGITTAL CRANIOSYNOSTOSIS IN INFANTS Russian patent published in 2024 - IPC A61B17/16 A61B17/80 A61L15/28 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to neurosurgery. Biauricular zigzag skin incision is made with a scalpel according to the preoperative marking. Subcutaneous fat is incised by monopolar coagulation. Plastic haemostatic clips are applied on the skin. Cranial vault is exposed from coronary sutures to lambdoid sutures by monopolar coagulation without damaging the periosteum with abduction of skin flaps forward and backward. Osteotomy is marked. High-speed bur is used to make two milling holes 1 cm behind the coronary suture in the parietal bones along the midline at distance of 4-5 cm from each other. Then, two parallel cuts are made from the cutter holes with the help of a high-speed drill from the coronal suture to the lambdoid suture. Bone fragment is formed in a projection of a sagittal suture. Performing haemostasis of venous parasagittal emissaria. Parietal bones are fragmented with a high-speed drill without separation of bone fragments from dura mater. Parietal bone cuts are performed as follows: parallel to the coronary suture at distance of 0.5-1 cm from the midline to the squamous suture, parallel to the squamous suture at distance of 0.5-1 cm from the coronary suture to the lambdoid suture, from the coronary suture to the lambdoid suture in the middle of the parietal bone, from the middle line to the squamous suture at distance of 1/3 of the parietal bone, from the middle line to the squamosal suture at distance of 2/3 of the parietal bone, parallel to the lambdoid suture at distance of 0.5-1 cm from midline to squamosal suture. Then the bone fragments are fixed by applying haemostatic gauze over them.

EFFECT: method enables to achieve cerebral decompression, prevent subcutaneous migration of bone fragments in the postoperative period, minimize the volume of the surgical intervention, reducing the level of intraoperative and postoperative blood loss, reducing the need for repeated operations and implantation of foreign bodies, achieving a quick cosmetic effect in the postoperative period.
