Ommaya reservoir implantation

Supine on surgical table.

Head in neutral position.

Neuro Navigation.

Kocher's point is used for access to the frontal horn of the lateral ventricle.

The trajectory for entry into the frontal horn of the lateral ventricle is toward the intersection of the medial canthus and tragus.

A semi-circular incision is made in the right frontal area.

A curvilinear incision was made in the right frontal region to expose Kocher's point.

A burr hole is placed at Kocher's point.

With stereotactic navigation, the ventricular catheter is inserted to a pre-measured depth of approximately 5.5 - 6 cm from the cortex.

The catheter is truncated and attached to the Ommaya reservoir.

The reservoir is placed posterior to the burr hole in a subgaleal pocket.

The incision is closed in layers.

The skin is closed with a running absorbable monofilament suture and sealed with Dermabond.
