METHOD FOR BILATERAL TRANSCILIARY SUPRAORBITAL CRANIOTOMY Russian patent published in 2022 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to neurosurgery. The patient is placed on the operating table in a supine position, with the head rigidly fixed in the median position, raised above the level of the chest by 15 angular degrees, the back of the head is pulled down, the chin is up, the head is rotated in a healthy direction. A skin incision is performed along the eyebrow line with a length of 50 mm, starting 4 mm laterally to the supraorbital notch, parallel to the direction of growth of hair follicles. The incision is continued along the eyebrow line, not reaching the projection of the frontal branch of the facial nerve. The muscle fibers m.orbicularisoculi and m.frontalis are bluntly separated in the direction from the upper edge of the eye socket upwards with the raspatory. The edges of the wound are separated, in the area of the front sphenoidal suture, laterally to the temporal line, in the direction of the base of the anterior cranial fossa, a burr hole is made. From the hole, using a craniotome, two cuts are performed: straight in the medial direction, the second, arcuate, to the junction with the first at the medial point itself, a craniotomy of 3.5 cm × 2.5 cm is obtained. The inner bone rim of the upper edge of the eye socket is removed. Archwise, with the base to the upper edge of the eye socket, the dura mater is opened. Manipulations are performed on the other side of the operated patient’s head, in the area of the other eyebrow, obtaining a second hole in the cranial bone measuring 3.5 cm × 2.5 cm.

EFFECT: method makes it possible to increase the safety and radicality of surgical treatment of patients with complex tumors of the anterior cranial fossa and chiasmal-sellar area and with multiple cerebral vascular aneurysms, reduce the traumatic nature of the intervention and the risk of postoperative complications, improve the working conditions of neurosurgeons and increase productivity.
