SUPRAORBITAL CRANIOTOMY BY FRACTURE OF THE ANTERIOR ORBITAL ROOF

The authors describe a new and rapid method to safely perform a suprao rbital craniotomy. This technique can be used when tumor does not inva de the orbital roof. Previous descriptions of the supraorbital craniot omy involved exposure of the frontal sinus by removing its anterior wa ll and using the Gigli saw to separate the orbital roof. This new appr oach avoids removal of the anterior frontal sinus wall and separates t he supraorbital bone flap from the calvaria by fracturing the anterior orbital roof forward. In addition, a method for harvesting a laterall y based pericranium and muscle pedicle that contains a section of cont ralateral temporalis muscle is described. This vascularized pedicle ca n be used for repair of cerebrospinal fluid leaks or bone defects alon g the anterior fossa floor and orbit.
