Click Here to View Part I
This exhibit illustrates the second part of a craniotomy and mastoidectomy procedure to repair a cerebrospinal fluid (CSF) leak. The dura was opened, exposing the temporal lobe for dural repair. DuraGen was placed under the temporal lobe along the interior surface of the dural tears. The dura was then closed with sutures and a second layer of DuraGen was placed over the epidural surface. Lastly, fixation of the craniotomy flap was accomplished with titanium micro-plates, and the tegmen defects were filled with bone cement.
