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...

BACKGROUND Endoscopic management of sphenoid sinus disease has great potential for surgical complications. A variety of endoscopic surgical techniques have been described for entering the sphenoid sinus. The utility of these surgical techniques is based on the position of the superior turbinate attachment to the sphenoid face (Parson's ridge). We introduce a novel computerized tomography (CT) g...

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...

Intraosseous lipoma is an uncommon mesenchymal tumor that is frequently found in appendecular skeleton. In extremely rare conditions, it can appear in sphenoid bone, and only 2 cases have been described in literature until now. We present a case of lipoma in the body of the sphenoid bone mimicking sphenoid sinus tumor. A 16-year-old man presented to Department of Otorhinolaryngology with a comp...

We have observed two contiguous mucoceles in one patient. Based on the mucoceles' signal intensities on MR imaging, as well as their anatomic location as delineated by CT and MR, we hypothesize that the "downstream" mucocele obstructed the "upstream" sinus, leading to formation of a secondary mucocele.

For operations of the pituitary glands, the most subtle method is an intervention through the paranasal and especially through the sphenoid sinus. To avoid dangerous interference with adjacent organs and nerves, the surgeon has to orient himself in the very small sphenoid cavity and navigate across the hollow space to break through the sellar floor to the pituitary gland above. Especially in re...

BACKGROUND Isolated sphenoid sinus pathologies are relatively rare. In the majority of cases, symptoms do not arise in the early stages of the disease or are non-specific, therefore making diagnosis difficult. The aim of this study was to investigate the diagnostic process and the reasons for development of complications in patients with isolated sphenoid sinus pathology. MATERIAL/METHODS The...

BACKGROUND AND PURPOSE The development of a new polyp or mass in the radiation field of a previously treated carcinoma is usually an ominous sign of a recurrent cancer, but rarely may it be caused instead by a nonmalignant process. The purpose of this study was to document the MR appearance of unusual nonmalignant polyps or masses (NMPMs) in the nasopharynx and sphenoid sinus arising after radi...
