BACKGROUND Multiple reports have demonstrated the efficacy of the transnasal endoscopic repair of cerebrospinal fluid (CSF) leaks of the anterior cranial base. The literature, however, lacks a comprehensive clinical study specifically addressing the transnasal endoscopic repair of CSF leaks of the sphenoid sinus. OBJECTIVE To ascertain the factors that significantly affect the surgical outcom...
INTRODUCTION AND OBJECTIVES Cerebrospinal fluid leaks associated to meningoencephaloceles of the sphenoid lateral recess are rare entities. A congenital bony defect at this level results in the persistence of Sternberg's canal, or a lateral craniopharyngeal canal, which is supposed to be the origin of these lesions. Our objective was to show that the endoscopic transpterygoid approach is an eff...
BACKGROUND Primary inverted papilloma of the sphenoid sinus is rare. The tumor is considered locally aggressive. In selected cases inverted papilloma can be associated with squamous cell carcinoma. Radiologic imaging is a key to an accurate diagnosis. AIM We analyzed patient with inverted papilloma in sphenoid sinus which was removed with endoscopic surgery. MATERIAL AND METHODS We discuss ...
OBJECTIVES/HYPOTHESIS Various intranasal landmarks have been described to aid in the localization of the natural sphenoid sinus ostium. The objectives of this study are to identify the ostium location relative to the skull base and assess the relationships between the location of the ostium and sphenoid disease or pneumatization pattern. DESIGN Descriptive study. METHODS Consecutive Xoran M...
Acute isolated sphenoid sinusitis is a rare and is seen in only 3% of all cases of all sinusitis. It is frequently misdiagnosed because of its vague clinical presentation. We report a case of 35year old female who presented to our emergency department with complaints of painless rapidly developing bilateral vision loss. Non contrast computed tomography of paranasal sinuses showed only mild opac...
Delayed epistaxis after head trauma is a common presentation of’ pseudoaneruysm, which should be investigated. Traumatic pseudoaneurysm of the intracavernous ICA is a rate condition resulting from fracture base of the skull. gunshot injuries to head or after surgery on pituitary fossa or sphenoid sinus. The pseudoaneutysni arises at the i nfrac I inoid port ion proximal to opthalmic artery and ...
We describe a practical technique of superior turbinectomy followed by posterior ethmoidectomy as a less invasive procedure for two-surgeon technique on endoscopic endonasal transsphenoidal surgery. After identification of the superior turbinate and the sphenoid ostium, the inferior third portion of the superior turbinate was coagulated and resected. This partial superior turbinectomy procedure...
Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated malignancy rate of 7 to 15%. Objectives...
Introduction Isolated disease of the sphenoid is rare and has often been overlooked due to its remote location and difficult access. Objective A retrospective study of the main causes of isolated sphenoid sinus diseases with discussion of the most appropriate methods of diagnosis and treatment. Methods A total of 46 cases of isolated sphenoid disease treated between January 2008 and December 20...
