Endoscopic surgical techniques allow treating various pathological diseases of the cranial base, including cerebrospinal fluid leaks (CSF). These approaches have a high success rate and reduce surgical time and morbidity. However, when they are located in the lateral wall of the sphenoid, the surgery is more complex. In our case, the CSF appeared to be related with a Sternberg's canal. Predispo...

OBJECTIVES To calculate the volume of bone in 3 areas of the deep lateral orbit that are available for removal in decompression surgery and to demonstrate these 3 areas within a 3-dimensional computed tomographic reconstruction of the orbit. DESIGN The 3 areas of bone in the deep lateral orbit were designated the lacrimal keyhole, the sphenoid door jamb, and the basin of the inferior orbital ...

Background Sphenoethmoid cells may be above the sphenoid sinus with/ or without con-tact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue. Aims The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus vol-ume using multiplanar com...

Background and Purpose Sphenoid bone fractures and sphenoid sinus fractures have a high morbidity due to its association with high-energy trauma. The purpose of this study is to describe individuals with traumatic injuries from different mechanisms and attempt to determine if there is any relationship between various isolated or combined fractures of facial skeleton and sphenoid bone and spheno...

BACKGROUND Primary involvement of the sphenoid sinus occurs in 2% of all paranasal sinus tumors and is associated with dismal prognosis. Optimal management remains debatable. METHODS A total of 23 patients were treated for a primary cancer of the sphenoid sinus from 1988 to 2004. Charts were reviewed for patient-, tumor-, and treatment-related parameters. Univariate and multivariate analyses ...

BACKGROUND Unilateral isolated sphenoid sinus disease (ISSD) is a rare diagnosis of the paranasal sinuses that can be associated with complications involving vascular, neurologic, and optic structures in close proximity. CASE PRESENTATION A 62 year old female presented to a hospital in Georgetown, Guyana with right lateral rectus palsy, diplopia, and a severe progressively worsening headache....

Solitary abducens palsy secondary to isolated sphenoid sinus disease (ISSD) is rare and early management is important. There is no report regarding the results of endoscopic sinus surgery (ESS) for prolonged abducens palsy due to ISSD. We present four cases of ISSD with solitary abducens palsy that received ESS from 1995 through 2000. The interval between onset of diplopia and ESS was longer th...

Surgery for cholesterol granulomas involving the petrous apex has traditionally been performed via a lateral skull base approach. We present a case-series of four cholesterol granulomas treated through the endoscopic-transsphenoid approach over the last 10 years. Drainage was successful and symptomatic improvement was obtained in all cases (follow-up 6 months-10 years). Primary 'sphenoid' lesio...

Treatment of static deformations the forefoot with valgus deformation first toe remains relevant today. Objective. Toanalyze results surgery severe hallux using corrective proximal wedge-shaped osteotomy I metatarsalbone and Lapidus arthrodesis. Methods. The surgical treatment 104 women (147 feet) halluxvalgus according to Mann classification were evaluated. Age — 27‒65 years, follow-up period ...
