BACKGROUND: Various approaches can be considered for decompression of the intracanalicular optic nerve. Although clinical experience has been reported, no quantitative study has yet compared the extent of decompression achieved by an endoscopic endonasal versus transcranial approach. OBJECTIVE: Toward this aim, our morphometric analysis compared both approaches by quantifying the circumferential degree of optic canal decompression that is possible before any meningeal violation, which would result in cerebrospinal fluid (CSF) leak...

Background  Most existing objective surgical motion analysis schemes are limited to structured surgical tasks or recognition of motion patterns for certain categories of surgeries. Analyzing instrument motion data with respect to anatomical structures can break the limit, and an anatomical region segmentation algorithm is required for the analysis. Methods  An atlas was generated by manually segmenting the skull base into nine regions, including left/right anterior/posterior ethmoid sinuses, frontal sinus, left and right maxillary sinuses, nasal airway, and sphenoid sinus...

Introduction  The petrous apex poses a challenge for surgical intervention due to poor access. As intraoperative image guidance and surgical instrumentation improve, newer endoscopic approaches are increasingly favored. This study aims to provide normative data on the anatomy of the lateral sphenoid sinus recess and petrous apex. These normative data could assist in determining the efficacy of a transnasal transsphenoidal approach to lesions of the anteroinferior petrous apex. Methods  This is a retrospective study investigating normative data on all maxillofacial computed tomography (CT) scans performed at a level I trauma center over a 6-month period...

Central nervous system (CNS) infections due to filamentous basidiomycetes are extremely rare. We encountered a case of epidural abscess due to Schizophyllum commune that extended from sinusitis. A 53-year-old Japanese man presented at our hospital with a headache. Computed tomography (CT) of the cranium and sinuses showed ethmoid and sphenoid sinusitis with no intracranial abnormalities. The patient was diagnosed with acute sinusitis and underwent antibiotic treatment. However, the symptoms deteriorated, and the patient came to our hospital again with consciousness disturbance...

OBJECTIVE The expanded endonasal endoscopic transsphenoidal approach has become increasingly used for craniopharyngioma surgery in the pediatric population, but questions still persist regarding its utility in younger children, in recurrent and irradiated tumors, and in masses primarily located in the suprasellar region. The narrow corridor, incomplete pneumatization, and fear of hypothalamic injury have traditionally relegated this approach to application in older children with mostly cystic craniopharyngiomas centered in the sella...

OBJECTIVE The endoscopic endonasal approach (EEA) has been shown to be an effective means of accessing lesions of the petrous apex. Lesions that are lateral to the paraclival segment of the internal carotid artery (ICA) require lateralization of the paraclival segment of the ICA or a transpterygoid infrapetrous approach. In this study the authors studied the feasibility of adding a contralateral transmaxillary (CTM) corridor to provide greater access to the petrous apex with decreased need for manipulation of the ICA...

An 86-year-old patient was hospitalized for fever and left acute orbital syndrome (red eye with moderate visual impairment, chemosis, ophthalmoplegia without proptosis, or any fundus involvement). CT scan showed superior ophthalmic vein and cavernous sinus enlargement complicating ipsilateral sphenoidal sinusitis. Magnetic resonance imaging (MRI) demonstrated the left cavernous sinus thrombosis extended to the ipsilateral jugular vein and transversal sinus (Lemierre syndrome). Intravenous broad-spectrum antibiotics and curative anticoagulation were prescribed...

BACKGROUND: The excellent visualization and minimally invasive approach employed in endoscopic endonasal procedures has now revolutionized the pituitary surgery, replacing the transnasal microscopic technique worldwide. However, it involves major shift in hand-eye co-ordination from static 3 dimensional images of microscope to 2 dimensional endoscopic images hence demands training and inter-disciplinary approach. Here we present our experiences in learning and developing a safe endonasal transsphenoidal endoscopic approach to resect pituitary adenomas...

Ewing's sarcoma is a high-grade neuroectodermal primary bone tumor. This is the second primary bone tumor in children afterosteosarcoma and represents 4 to10% of cases. It can occur in all skeletal bones. However, the location at the facial bones is uncommon (1to2%) and extremely rare at the sphenoid sinus. We report the clinical results of a rare case of Ewing's sarcoma of the sphenoid with intraorbitaland intracranial extension.

Gmaan Alzhrani, William Couldwell
Bony hyperostosis is commonly associated with meningioma growth and is considered one of the characteristic signs on imaging; however, recurrence of meningiomas in the sphenoorbital area, including associated hyperostosis, is typically precluded by gross total resection of the lesion. This 63-year-old man presented with progressive double vision and proptosis in the right eye. He underwent frontotemporal craniotomy and partial removal after magnetic resonance imaging demonstrated a right sphenoorbital meningioma extending to the orbit and middle fossa...

OBJECTIVES/HYPOTHESIS: Balloon dilation (BD) represents a minimally invasive alternative to endoscopic sinus surgery (ESS). Although BD was introduced in 2006, distinct Current Procedural Terminology (CPT) codes were not available until 2011, making prior analysis of population-based trends difficult. Our objectives were to evaluate these trends and compare any changes to the use of traditional ESS techniques. Geographic trends also were evaluated. METHODS: Medicare Part B national datasets encompassing procedures from 2011 to 2015 were obtained...
