OBJECTIVES This study aimed to investigate the anatomy of the intraorbital structures regarding to endoscopic sinus surgery and external frontal sinus surgery analyzing computer tomography (CT) scans. METHODS The CT scans of 100 patients were retrospectively evaluated. The anatomic relationships between the intraorbital structures and paranasal structures were measured using multiplanar recon...

BACKGROUND Sinonasal neuroendocrine carcinoma (SNEC) is a rare, aggressive tumor usually associated with a poor prognosis. This study analyzes the clinicopathological characteristics and survival outcomes of SNEC using population-based data. METHODS The Surveillance, Epidemiology, and End Results (SEER) database (1973 to 2011) was queried for SNEC cases. Data analyzed included patient demogra...

OBJECTIVES/HYPOTHESIS Bacterial biofilms (BBF) and osteitis are potential contributors to the local inflammatory load in chronic rhinosinusitis (CRS). This study investigated the relationship between BBF and osteitis status in CRS patients. STUDY DESIGN Prospective cohort study. METHODS Eighty-four CRS patients undergoing endoscopic sinus surgery and 22 control patients were enrolled in thi...

INTRODUCTION Osteomas are slow- growing, benign tumors. They are the most common neoplasms of the paranasal sinuses. They are usually originates from the frontal and ethmoid sinus and much less frequently seen in the maxillary and sphenoid sinuses. Although the lamina papyracea is a part of ethmoid bone, a giant osteoma originated from the lamina papyracea is very uncommon. An osteoma of the pa...

Ossifying fibroma is a benign fibro-osseous tumour that rarely involves the ethmoid sinuses and orbit. It is classified as a benign fibroosseous lesion, a term that is synonymous with a variety of lesions reported in the literature. Recurrence rate with deleterious effects in cases of extramandibular ossifying fibroma is the impetus for open en bloc resection of the tumour. Continuously evolvin...
