4Midface and skull reconstruction using Intraoperative navigation

Tracking of patients head is achieved with a dynamic reference frame (DRF) attached to the cranial bone. Alternatively the DRF can be attached to a Mayfield clamp.

The pointer is placed on the surface of the titanium mesh at the medial wall of the left orbit to correlate mesh position and virtual reconstruction with infrared navigation.

This procedure has to be repeated after any changes of mesh position.

The stable fixation of the mesh follows confirmation of correct position. This is performed as described in the trauma secttion.
