The primary objective of this study was to evaluate morbidity associated with facial translocation approaches for skull base and results of various technical modifications. Forty consecutive patients who underwent facial translocation approaches for accessing skull base tumors from July 2005 to June 2010 were included in this study. There were 25 patients who underwent standard facial translocation, 4 patients medial mini, and 11 patients underwent extended facial translocation. Thirteen patients had benign disease and 27 patients had malignant disease...

We performed a trauma database analysis to identify the effect of concomitant cranial injuries on outcome in patients with fractures of the axis. We identified patients with axis fractures over a 14-year period. A binary outcome measure was used. Univariate and multiple logistic regression analysis were performed. There were 259 cases with axis fractures. Closed head injury was noted in 57% and skull base trauma in 14%. Death occurred in 17 cases (6%). Seventy-two percent had good outcome. Presence of abnormal computed tomography head findings, skull base fractures, and visceral injury was significantly associated with poor outcome...

We present a retrospective analysis of surgical outcome of sinonasal malignant tumors. Overall survival (OS), disease-specific survival (DSS), local control (LC), and disease-free survival (DFS) were calculated in 32 patients. Prognostic factors for survival and functional outcomes were investigated. The median follow-up period was 70 months. At 5 years, OS, DSS, LC, and DFS rates were 0.722, 0.745, 0.851, and 0.707, respectively. Prognostic factors for poor OS were involvement of the frontal sinus (p = 0...

Complex intracranial aneurysms (CIAs) include those classified as giant, those located in brain regions of technically difficult access, or that involve arterial trunks/branches, and/or have complicated wall structure. We reviewed retrospectively our management of such lesions in a 12-year period. From 1997 to 2009, 192 patients were admitted with CIAs (133 females, 59 males; average age 55 years); 128 presented with subarachnoid hemorrhage (SAH) and 64 with unruptured, symptomatic CIAs. The SAH group had 73 anterior- and 55 posterior-circulation aneurysms...

There has been increasing experience in the utilization of intraoperative magnetic resonance imaging (iMRI) for intracranial surgery. Despite this trend, only a few U.S centers have examined the use of this technology for transsphenoidal resection of tumors of the sella. We present the largest series in North America examining the role of iMRI for pituitary adenoma resection. We retrospectively reviewed our institutional experience of 59-patients who underwent transsphenoidal procedures for sellar and suprasellar tumors with iMRI guidance...

We explored the general feasibility of proton beam therapy for chordoma and chondrosarcoma of the skull base. Clinical records and treatment-planning data of patients with the pathological diagnosis of chordoma or chondrosarcoma were examined. Proton beam therapy was administered for gross tumor mass as well as microscopic residual disease after surgery. The prescribed dose was determined to maximize the coverage of the target and to not exceed predefined constraints for the organs at risk. Eight cases of chordoma and eight cases of chondrosarcoma were enrolled...

We assessed the accuracy of a surgeon's localization of sella margins during endoscopic transsphenoidal surgery for pituitary adenomas, as verified using a neuronavigational system, and we identify types of pathology in which neuronavigation is of most benefit. We performed a prospective cohort study of 32 consecutive patients undergoing image-guided endoscopic transsphenoidal surgery for pituitary adenomas. We assessed the margin of error in the surgeon's localization of the superior and inferior margins of the sella and the lateral margins as determined by the medial border of left and right carotid arteries, using a magnetic resonance-based neuronavigational system...

Anupama D Bedi, Steven A Toms, Amir R Dehdashti
The endoscopic endonasal approach offers a wide, panoramic exposure of the sellar floor, planum, and clivus. The ability to expose fully the tumor margins, through lateral extension of cavernous sinuses, increases the exposure and ability to resect the tumor but increases the risk of bleeding. The authors describe achieving hemostasis using a hemostatic matrix, FloSeal (Baxter Biosciences, Vienna, Austria) sealant, during endoscopic endonasal tumor removal, specifically for pituitary and suprasellar tumors...

During the last years, multiple methods and a wide set of materials for skull base reconstruction have been described. In our experience, the ideal graft for duraplasty is the iliotibial tract due to its favorable characteristics in terms of thickness, pliability, and strength. In this report, we show the iliotibial tract-harvesting technique under endoscopic guidance with a minimally invasive approach using a cadaveric model. Two longitudinal incisions of 1 cm each were made at 4 cm down a line drawn between the anterior-superior iliac spine and the lateral margin of patella at the extremities of the middle third of the thigh...

The facial nerve is one of the most commonly injured cranial nerves. Once injured, the effects on form, function, and psyche are profound. We review the anatomy of the facial nerve from the brain stem to its terminal branches. We also discuss the physical exam findings of facial nerve injury at various levels. Finally, we describe various reconstructive options for reanimating the face and restoring both form and function.

JOURNAL ARTICLE
Haim Ezer, Anirban Deep Banerjee, Cedric Shorter, Anil Nanda
The "Agnes Fast" craniotomy is a fast and simple way of performing the pterional craniotomy while preserving the temporalis muscle, together with its fascia and bony attachment. Using this technique, the surgeon need not divide the temporalis muscle, separate it from its bony attachment, or perform an interfacial dissection. With a little practice, this craniotomy can be performed in less than 5 minutes and is highly recommended in emergent settings. The modified pterional craniotomy was performed in 10 cadaveric specimens, preserving the temporalis muscle with its attachment...

We sought to characterize the effectiveness of concomitant chemoradiotherapy (CCRT) for patients with squamous cell carcinoma of the temporal bone. We performed a retrospective chart review of 14 patients with cancer of the temporal bone who were provided initial treatment in our hospital from December 2001 to November 2008. Four patients with stage I tumors were treated by radiation therapy alone or with oral administration of S1. One patient with a stage II tumor was treated by radiation therapy concomitant with low dose docetaxel...

Adding posterolateral orbitotomy to pterional craniotomy allows greater exposure of the anterolateral skull base. However, there is a paucity of literature quantifying the relative benefit of adding posterolateral orbitotomy for various surgical targets. Our study is a step to address this issue. We performed dissections of five cadaveric heads (10 sides). The anterior communicating artery (A-Com) complex, posterior chiasm (anterior third ventricular region), ipsilateral optic canal, and ipsilateral supraclinoid internal carotid artery (ICA) bifurcation were chosen as targets...

JOURNAL ARTICLE
Corrie E Roehm, Seth M Brown
Cerebrospinal fluid (CSF) leak closure remains one of the most difficult surgeries for skull base surgeons, particularly with frontal sinus involvement. Technological advances in endoscopic surgery increasingly allow for less morbid approaches to the frontal sinus. We describe a series of patients who underwent endoscopic frontal sinus CSF leak repair utilizing a unilateral approach, to evaluate the utility and outcomes of this method. We performed a retrospective review of four cases in tertiary care centers...

Solitary fibrous tumors (SFTs) are uncommon neoplasms of mesenchymal origin that were first described as primary spindle-cell tumors of the pleura in 1931. Since then, infrequent case reports of extrapleural SFTs have been described including various subsites within the head and neck. Based on a review of the literature and a description of the endoscopic treatment of three patients with SFTs of the nasal cavity and ethmoid sinuses, the challenges associated with the management of sinonasal SFTs are discussed...
