Chronic invasive granulomatous fungal sinusitis (CIGFS) caused by cryptococcus is extremely rare, especially in immunocompetent patients. We report two cases of CIGFS caused by cryptococcus in immunocompetent patients. Case 1 was infected in the left ethmoid sinus with orbital invaded later. Case 2 was infected in the left maxillary sinus and sphenoid sinus with Intracranial invaded later. The ...

Background Precise knowledge of anatomic variations of nose and paranasal sinus complex is essential for achieving best surgical results during endoscopic sinus surgery. Computed tomography is the gold standard investigation for evaluation of paranasal sinuses and adjacent structures. Objective To study prevalence of anatomical variations of nose, paranasal sinuses and osteomeatal complex and t...

INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...

OBJECTIVES To evaluate the pathologic conditions, preoperative evaluation, treatment, and clinical outcomes associated with sphenoid sinus disease. DESIGN Retrospective study. SETTING Tertiary university-based referral center. PATIENTS All patients with isolated sphenoid sinus disease managed surgically or in which surgery was considered a primary treatment option. MAIN OUTCOME MEASURES...

T he infratemporal fossa (ITF) is a rare anatomic site for abscess formation. Infections in this space have been found following maxillary sinusitis, maxillary sinus fracture, temporomandibular arthroscopy, dental infection, and tooth extraction. The ITF is bounded superiorly by the sphenoid bone, medially by the lateral pterygoid plate, anteriorly by the maxilla, posteriorly by the deep paroti...

Extension of sphenoethmoiditis into the orbital apex may result in visual loss and ophthalmoplegia, but minimal signs of orbital pathology such as proptosis, chemosis, or lid edema. This entity is termed orbital apex syndrome. The case of a 74-year-old woman with orbital apex syndrome and irreversible unilateral visual loss secondary to bacterial sphenoethmoiditis is presented. This case, and o...
