Venous sinus techniques: Superior sagital (longitudinal) sinus:
-The overlapping thumbs are placed above the external occipital protuberance.
-The palms of the hands are lying on the external surface of the head.
-The thumbs are putting a gentle spreading pressure on the tissue at the level of the superior longitudinal sinus.
-After a softening of the tissue the thumbs are moved one finger’s width anterior-cranial.
This procedure is repeated along the sagital suture up to Bregma.
- Following this, the fingers of both hands are placed along the metopic suture on the frontal bone. The index fingers are anterior to bregma, the little fingers are above nasion. The other fingers are lying in-between.
-We follow the same principle as above.
Dural techniques: Release of the falx cerebri
Frontal spread technique:
-The ring fingers hook around the zygomatic process of the frontal bone and use it as an attachment.
-The little fingers support the ring fingers.
-the middle fingers and index fingers are next to the medial line of the frontal bone.
-One thumb is under the hand, one thumb is over the hand.
-the index fingers give a slight pressure posterior at the midline of the frontal bone. This decreases the anterior-posterior diameter of the falx and reduces its membranous tension.
-Once no further relaxation takes place or a stillpoint has appeared, one can move on to the lift technique.
