BACKGROUND Sinonasal complications are common in children with cystic fibrosis (CF). Generally, those children with persistent symptoms of sinonasal polyposis are referred to an otorhinolaryngologic (ORL) physician for sinus surgery. Several studies have reported differences in clinical characteristics between CF patients with and without sinonasal polyps. OBJECTIVES To predict the presence o...

Schwannomas or neurilemmomas are tumors of benign nerve sheath, and between 25 and 45% of all arise in the head and neck region. Less than 4 % are found in the sinonasal tract and their diagnosis may have difficulty due to non-specific symptoms and image characteristics. In several cases, complete surgical removal by endoscopic approach is the treatment of choice in these tumors. We report the ...

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...

PURPOSE In order to define specific features on screening sinus CT (SSCT) that will aid the endoscopic surgeon in his approach to patients with inflammatory sinonasal disease, we sought to answer four questions: 1) what recurring patterns of inflammatory sinonasal disease are evident on SSCT; 2) what is the relative frequency of these recurring patterns; 3) how do these CT patterns correlate wi...

INTRODUCTION Authors report their clinical experience in managing a 46-year-old male patient with long lasting nose breathing difficulties caused by nasal obstruction due to a large bilateral tumor masses in both nasal cavities. CASE OUTLINE Physical examination, laboratory and biochemistry analyses, as well as computed tomography showed an inhomogeneous soft-tissue tumor mass completely fill...
