b a c k ground: over the past decades, instruments and techniques of the transsphenoidal approach have improved greatly. all of these procedures, whether microscopic or endoscopic, must pass through the sphenoid sinus to reach the lesions. the sphenoid sinus is surrounded by several vital anatomical structures. knowing the details of the anatomy of the sphenoid sinus and the extent of pneumatiz...
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 surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...
Sphenochoanal poyp is rare nasal mass that originates from sphenoid sinus. In anterior rhinoscopy it may be mistaken with antrochoanal polyp. CT of paranasal sinuses and nasal endoscopy has increased diagnostic accuracy. Simple polypectomy without removal of intra sinus mass is associated with increased risk of recurrence. Treatment of sphenochoanal polyp must include removal of intrasphenoid...
A conchal non-pneumatized sphenoid sinus was previously considered to be a contraindication to the endoscopic transsphenoidal route to the sella due to its small sellar floor and poor anatomical landmarks, such as the optic nerve canal, opticocarotid recess and internal carotid arteries canal. The present study aimed to investigate the methodology and characteristics of the endoscopic transsphe...
PURPOSE OF REVIEW To review cause, clinical evaluation, medical and surgical management of isolated sphenoid sinus diseases. RECENT FINDINGS Early diagnosis of isolated sphenoid sinus diseases requires a high index of clinical suspicion and appropriate radiological imaging. Sphenoid sinus can be approached endoscopically via a few different surgical techniques. SUMMARY Isolated sphenoid sin...
OBJECTIVES The aim of this study was to evaluate patients who underwent endoscopic sphenoid sinus surgery for isolated sphenoid sinus disease. We also investigated the impact of sphenoid sinus surgery on headache intensity. MATERIAL AND METHODS Twenty-one consecutive patients who underwent endoscopic sphenoidotomy for isolated sphenoid sinus disease were included in the study. Diagnosis of is...
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 ...
ABSTRACT The Sphenoid Sinus is considered the paranasal sinus with more variation to degree of pneumatization. Thus, this work aimed report first case on interference anatomical for orthognathic surgery. A 18- year-old woman, isolated cleft palate repaired, was submitted surgery correct maxillomandibular skeletal discrepancy. cone beam computed tomography (CBCT) exam performed preoperative plan...
Objectives: Cholesterol granuloma of the sphenoid sinus has rarely been reported. Methods: A 50-year-old man visited our hospital presenting with a 2-year history of intermittent right-sided headache, 1-month history of right-sided tinnitus, and 5-year history of nasal obstruction and purulent nasal discharge. Computed tomography revealed a well-demarcated expansile mass in the right sphenoid s...
