Nasopharyngeal carcinoma (NPC) may spread to the paranasal sinuses. This retrospective study describes the features of paranasal sinus involvement in NPC on computed tomography (CT) and magnetic resonance imaging (MRI). One hundred and fourteen patients with histologically proven NPC underwent staging with both CT and MRI. Maxillary sinus infiltration was demonstrated on MRI in 10 patients; sph...

BACKGROUND Exenteration is indicated in patients with malignant neoplasms of orbital contents. It entails the removal of the eyeball together with its extraocular muscles and other soft tissues. Exenterations can be classified into (1) total, (2) subtotal, and (3) supertotal exenteration. Retrospectively study, we reviewed 7 patients that had received exenteration/subtotal exenteration with spo...

BACKGROUND The purpose of this study was to evaluate the results of a mono-institutional series of patients treated with anterior craniofacial resection for malignant paranasal sinus tumors. METHODS We analyzed all patients with malignant paranasal sinus tumors treated with anterior craniofacial resection at our institution between 1987 and 2007. All tumors were classified according to both t...

Introduction: Anatomic variations of the paranasal sinuses are very common. Paranasal sinus

Treatment monitoring of paranasal tumors is crucial, given the high rate of local and regional relapses that impairs the overall prognosis of patients. Magnetic resonance imaging (MRI) is the technique of choice to detect changes in the submucosa and deep spaces of the suprahyoid neck, inaccessible at clinical and endoscopic assessment. Correct interpretation of MRI requires detailed knowledge ...

BACKGROUND Glomangiopericytoma is an uncommonly encountered tumor of the nose and paranasal sinuses, accounting for <0.5% of all sinonasal tumors. Extension of these lesions to the anterior or middle cranial fossa is rare. When this occurs, diagnosing glomangiopericytoma is extremely challenging, as it is often confused with other anterior skull base tumors. CASE DESCRIPTION We report a case ...

Introduction: Anatomic variations of the paranasal sinuses are very common. Paranasal sinus

statement of problem: variation in paranasal sinus anatomy as shown on computed tomographic scans is of potential significance for it may pose risks during surgery or predispose to certain pathologic conditions. purpose: the aim of this study was to assess the relative frequency and concurrence of variations in paranasal sinus anatomy in a given population and to compare the results with previo...

BACKGROUND The authors reviewed treatment results in patients with nasal and paranasal sinus carcinoma from a large retrospective cohort and conducted a systematic literature review. METHODS Two hundred twenty patients who were treated between 1975 and 1994 with a minimum follow-up of 4 years were reviewed retrospectively. A systematic review of published articles on patients with malignancie...
