This exhibit depicts the second part of a bifrontal craniotomy procedure to repair multiple traumatic head injuries. The frontal sinus fracture is drilled out with a burr. Next, a harvested piece of temporalis muscle is placed in the frontonasal ducts and covered with Bio-Glue. A harvested piece of pericranial flap is then reflected into the frontal sinus and under the floor of the frontal lobe to prevent CSF leak (proper sealing accomplished with Bio-Glue). Fixation of the supraorbital ridge, facial fractures, and frontal bone flap is accomplished with mini-plates and screws.
