The authors present a surgical approach that incorporates the frontal sinus and extends a supraorbital craniotomy to include the lateral orbital rim and zygoma. The craniotomy provides wide exposure of the anterior fossa, orbit, ipsilateral middle fossa, and cavernous sinus. The procedure can be performed easily, and the bone flaps can be secured rapidly(More)
The authors describe a new and rapid method to safely perform a supraorbital craniotomy. This technique can be used when tumor does not invade the orbital roof. Previous descriptions of the supraorbital craniotomy involved exposure of the frontal sinus by removing its anterior wall and using the Gigli saw to separate the orbital roof. This new approach(More)
OBJECT Surgical intervention may be required if endovascular embolization is insufficient to completely obliterate intracranial dural arteriovenous fistulas (DAVFs). The authors report their 14-year experience with 23 patients harboring diverse intracranial DAVFs that required surgical intervention. METHODS Between 1993 and 2007, 23 patients underwent(More)
The intracarotid sodium amobarbital (Amytal) test, the Wada test, remains an efficient test for evaluation of language and memory function. However, due to a world shortage of amobarbital, it has become necessary to investigate the use of alternatives. We report the efficacy of the Wada test using secobarbital sodium (Ional) in determining language(More)
OBJECT Use of orbital rim and orbitozygomatic osteotomy has been extensively reported to increase exposure in neurosurgical procedures. However, there have been few attempts to quantify the extent of additional exposure gained by these maneuvers. Using a novel laboratory technique, the authors have attempted to measure the increase in the "area of exposure"(More)
OBJECT The purpose of this study was to evaluate the far-lateral transcondylar transtubercular approach (complete FLA) based on quantitative measurements of the exposure of the foramen magnum and petroclival area obtained after each successive step of this approach. METHODS The complete FLA was reproduced in eight specially prepared cadaveric heads (a(More)
Bilateral coronal synostosis often results in a turribrachycephalic skull shape. Reduction of skull height and elongation of the anteroposterior axis of the skull while preserving normal cerebral function are the major therapeutic goals. A surgical technique is described which can successfully accomplish these goals in a single operative procedure.
OBJECT The optimal timing of cranioplasty after decompressive craniectomy for stroke is not known. Case series suggest that early cranioplasty is associated with higher rates of infection while delaying cranioplasty may be associated with higher rates of bone resorption. The authors examined whether the timing of cranioplasty after decompressive craniectomy(More)
OBJECT The authors prospectively evaluated the safety and efficacy of a novel polyethylene glycol (PEG) hydrogel sealant in patients undergoing elective cranial surgery with documented cerebrospinal fluid (CSF) leakage after sutured dural repair. METHODS The PEG hydrogel sealant was used at 11 different study sites in 111 patients with documented(More)
The authors report a novel technique for the treatment of cholesterol granulomas. An extradural middle fossa approach was used to access the granuloma, with drainage through silastic tubes into the sphenoid sinus via the anteromedial triangle between V1 and V2. Cholesterol granulomas occur when the normal aeration and drainage of temporal bone air cells is(More)
