metastatic   tumors in the nose and paranasal sinuses are infrequent. the origin of this metastatic tumors are often renal cell carcinoma. we present one case of metastatic renal cell carcinoma   to the nose and paranasal sinuses ,4 years after initial nephrectomy and diagnosis of stage t1n0m0 clear cell carcinoma. the patient complained of nasal obstruction and recurrent epistaxis   who was tr...

OBJECTIVES To quantify the safety and efficiency of Postgraduate-Year II head-and-neck-surgery residents who perform endoscopic sinus surgery, to observe any changes that accompanied accrued experience, and to measure and correlate blood loss and temporal efficiency with anesthesia-induced relative hypotension. DESIGN Retrospective study. SETTING University of California, San Diego, Medical...

Introduction Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis. Material...

OBJECTIVE To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. METHOD Sinus manometry was performed 5 times during inhalation. RESULTS The resemblance of pressure values comparing those treated with minimally invasive surgery an...

Fifty years ago, the extracorporeal cold light and its transmission by glass fibers, along with the Hopkins rod lens system, were introduced. The development and application of these new technologies to upper airways allowed studying, understanding, and improving knowledge of the anatomy, physiology, and diseases of the nasal cavity and sinuses. In particular, some fundamental concepts of moder...

OBJECTIVES We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. MATERIALS AND METHODS A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department ...

Introduction: Isolated sphenoid sinus inflammatory diseases (ISSIDs) are responsible for about 75% of isolated sphenoid sinus opacifications. Computer tomography (CT) and magnetic resonance imaging (MRI) should be used in a complementary manner for the assessment of ISSIDs. This evaluation sheds some light on the extent of disease and intracranial and intra-orbital involvement. ...
