OBJECTIVE To determine whether or not patient race and ethnicity affect sinonasal cancer survival. STUDY DESIGN Retrospective database analysis. SETTING National Cancer Institute's Surveillance, Epidemiology, and End Results Database, 1988-2010. SUBJECTS AND METHODS Sinonasal carcinoma cases were extracted according to site codes and histology recode-broad groupings. The cohort was used t...

Introduction and Objectives: Sinonasal tumours represent only 3% of all head and neck cancers. Adenocarcinoma is the second most frequent histopathology type. Hardwood exposure has been considered a risk factor. Sinonasal adenocarcinoma grows silently which leads to a late diagnosis and low survival rates. The aim of this study was to present our experience in the management of the patients wit...

INTRODUCTION AND OBJECTIVES The high variability of sinonasal anatomy requires the best knowledge of its three-dimensional (3D) conformation to perform surgery more safely and efficiently. The aim of the study was to validate the utility of Osirix® and stereolithography in improving endoscopic sinonasal surgery planning. METHODS Osirix® was used as a viewer and Digital Imaging and Communicati...

it is in cancers of the maxillary sinus. However, there have been no randomized prospective studies regarding occult metastasis of these cancers. Traditionally, elective neck dissection of clinically N0 neck is delayed after primary resection of maxillary cancer. Recently, many authors have agreed that regional metastasis of maxillary cancer is aggressive and comparable to cancers of tongue and...

BACKGROUND The level of p53 protein expression in sinonasal squamous cell carcinoma (SNSCC) has been estimated, but the results remain inconsistent and the point of consensus has not been reached. This study was first determined to evaluate the clinical effects of p53 expression in SCC of the sinonasal tract. METHODS According to the preferred reporting items for systematic reviews and meta-a...

Most of the sinonasal tumours are of epithelial origin. Smooth muscle tumours are extremely rare, they account for less than 2.5% of the mesenchymal neoplasms of the sinonasal tract and the nasopharynx. Fewer than 30 cases of primary leiomyogenic tumours have been reported in the sinonasal tract with almost an equal frequency of benign and malignant types. We report a case of a rare leiomyoma o...

OBJECTIVE Chronic rhinosinusitis (CRS) is a heterogeneous and multifactorial disease characterized by dysregulated inflammation. Abnormalities in innate immune function including sinonasal epithelial cell barrier function, mucociliary clearance, response to pathogen-associated molecular patterns (PAMPs) via pattern recognition receptors (PRRs), and the contribution of innate immune cells will b...
