BACKGROUND Recalcitrant sphenoid sinusitis occurs in 27% of patients undergoing revision functional endoscopic sinus surgery. One of the main causes of disease recurrence in the sphenoid is cicatricial scarring of the ostium. Highly inflammatory lesions such as fungal balls or chronic mucoceles can predispose patients to restenosis. We present a novel use of a modified nasoseptal flap to cover ...
Aims: Sphenoid sinus is one of the most inaccessible paranasal sinus, and is closely correlated to many vascular and neural structures. Anatomic variation of the sphenoid sinus can complicate surgery in this area. The aim of the present investigation was to define the sphenoid sinus variations and the relevant structures using cone-beam computed tomography (CBCT). Methods: This cross-sectiona...
OBJECTIVES A sphenoid sinus fungal ball is a rare disease that can cause visual disturbances. Most afflicted patients remain in an indolent state. However, once the visual disturbance has occurred, the recovery rate is very low. The purpose of this study was to overview the clinical characteristics of patients with a sphenoid sinus fungal ball and ascertain factors possibly related to the occur...
The purpose of this study is to determine the anatomical features of the sphenoid sinus using computerized tomography (CT). 100 Sudanese subjects were investigated for CT sinuses; Characterization of the sphenoid sinus and seven horizontal and vertical measurements were evaluated. Onodi cell was found in 13 subjects, 10 of them were sellar and 3 were pre-sellar. Pneumatization was of the sellar...
Adenocarcinomas of the sphenoid sinus are exceptional. In this paper, we report a new case with a review of the literature. Our patient was a 45-year-old man who presented with isolated retro orbital headache. CT and MRI suspected a malignat tumor of the sphenoid sinus. The patient underwent a debulking surgery. The final pathology carried out the diagnosis of primary adenocarcinoma. The patien...
Isolated sphenoid sinus mucocele is a rare entity. Here we report a case of isolated sphenoid sinus mucocele in a 9 years old girl presenting with unilateral blindness and without any sinonasal complaints. C.T. scan revealed an isolated sphenoid sinus mucocele which was managed endoscopically. A brief review of literature is also included.
purpose : to report a patient with sphenoid sinus mucocele (ssm) case report : the patient is a 19-year-old man who was referred to khatam-al-anbia eye center as retrobulbar optic neuritis. brain and orbital ct scan and mri revealed ssm. the patient underwent endoscopic sinus surgery and visual acuity (va) improved from no light perception (nlp) to 2 meter counting fingers. conclusion : ssm may...
BACKGROUND Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place. OBJECTIVE To outline the surgically risky anatomic variants of the sphenoid sinus as well as the variable relationsh...
Chronic sphenoid rhinosinusitis is a spectrum of inflammatory diseases in isolated sphenoid sinus which may persist over a period of 12 weeks. It is a different entity from other types of rhinosinusitis because clinical presentations include headache, visual loss or diplopia, and patients may or may not have nasal obstruction or nasal discharge. Nasal endoscopic examination is useful, and compu...
Ten percutaneous transnasal sphenoidotomies were performed in nine children; and in seven, a sphenoid window was also created. All procedures were performed in the special procedures laboratory, with biplane fluoroscopic guidance used in each case. Under general anesthesia, with the child in the supine position, a 14-gauge antral trocar was placed transnasally into the sphenoid sinus. The sinus...
