mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. when the mucocele content becomes infected, the lesion is defi ned as mucopyocele. most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation ...

PURPOSE OF REVIEW New developments in the nasal and paranasal sinus cancers are reviewed. RECENT FINDINGS In addition to woodworking, several risk factors for nasal and paranasal sinus cancers have been identified, most notably smoking. Progress in the differential diagnosis of small round cell nasal and paranasal sinus cancers allows the precise diagnosis of esthesioneuroblastoma. Despite re...

OBJECTIVES This study presents the role of the temporalis muscle flap in primary reconstruction after orbital exenteration. METHODS A retrospective nonrandomized study of orbital exenterations performed between 1990 and 2010 for malignant tumors of the skin, paranasal sinus, and nasal cavity is presented. RESULTS The study included 13 patients (nine men, four women; age range, 30-82 years) ...

Objective Paranasal sinus osteomas are benign tumors that are smooth-walled, slow-growing, and induced by bone tissue. Although their most common localization is the frontal sinus, some osteomas are seen in the ethmoid, maxillary, and sphenoid sinuses. Frontal sinus osteomas are often asymptomatic; however, when they become symptomatic, headache is the most common complaint. In this study, we a...
