BACKGROUND Eosinophilic chronic frontal sinusitis is difficult to treat compared with non-eosinophilic sinusitis because of recurring inflammation and polyp formation in the frontal recess after the post-operative follow-up period. Studying inflammatory mediators in the frontal recess of eosinophilic chronic rhinosinusitis (ECRS) patients and non-eosinophilic chronic rhinosinusitis (non-ECRS) p...

Background: Over the past decade, the indications of endoscopic surgery had been applied to the selected cases of malignant tumors. The acceptable morbidity and outcomes suggested that this technique could be available for the management of sinonasal malignant tumors. Objectives: To present our initial experience with the novel technique, modified transitional endoscopic maxillary, improve meth...

OBJECTIVE To determine histology, staging, and survival for pediatric sinus cancer. METHODS Cases of pediatric sinus cancer (maxillary, ethmoid, and frontal/sphenoid) were extracted from the Surveillance, Epidemiology, and End Results database (1988-2005). Demographic data were tabulated and non-lymphoid malignancies were staged according to the TNM system. Kaplan-Meier survival analyses were...

Many operations have been devised and are performed for the surgical treatment of severe chronic inflammatory disease and polYPosis of the ethmoid . Although internal transnasal ethmoidectomy was discredited for many years because of possibly severe complications, it is now regaining in popularity and is preferred over external transmaxillary and transfacial procedures [1-3) . This is the resul...

It seems apparently that the 2 separate anatomical areas (nasal cavity and paranasal sinus mucosa) are indeed one single unit with an identical behavior during inflammatory process. Similar histopathologic evidence in long-term condition could emphasize on the concept of rhinosinusitis in patients with inflammatory paranasal sinus disease. Prospective study was performed on 50 consecutive patie...
