OBJECTIVES/HYPOTHESIS The role of respiratory viral infection in the pathogenesis of chronic rhinosinusitis (CRS) has been rarely studied and remains controversial. The aim of this study was to explore the prevalence of respiratory viruses in the chronic status of CRS. STUDY DESIGN A case-control prospective study. METHODS Fifty-three control subjects, and 67 CRS with nasal polyp (CRSwNP) a...

Symptoms of chronic rhinosinusitis (CRS) are nasal blockage, nasal discharge, postnasal drip, facial pain, headache, and reduction or loss of smell, but they are often subtle and make it difficult to obtain a firm diagnosis based only on clinical data, and especially to distinguish CRS from persistent rhinitis. A diagnosis of certainty of CRS relies upon either direct observation by nasal fibro...

Introduction: The position of the sphenopalatine artery is essential for the endoscopic treatment of severe posterior epistaxis. This artery passes through its own foramen, which has a wide range of locations and anatomic relations. Objective: To carry out a descriptive osteological study on the sphenopalatine foramen area. Its anatomy, size, position and relations with turbinates and choanae a...

OBJECTIVE To evaluate nasal airflow characteristics during physiologic breathing in normal and pathologic conditions. DESIGN The choana of an anatomical human model was connected to a pump that simulated physiological pressure changes in the upper airway system. Normal ambient air was used as medium. The airstream was marked with aerosolized water particles, and was observed through an exact ...

BACKGROUND Nasal polyps are benign mucosal protrusions into the nasal cavity of multifactorial origin and are characterized by chronic mucosal inflammation. They result from the prolapsed lining of the ethmoid sinuses and block the nose to a variable degree depending on their sizes. This study aims to evaluate the clinical profile and management of nasal polyposis as seen in Ibadan, Nigeria. ME...

BACKGROUND Packing after closed reduction of nasal fracture causes uncomfortable nasal obstruction in patients. We packed the superior meatus with synthetic polyurethane foam (SPF) to support the nasal bone, and packed the middle nasal meatus with a nasal airway splint (NAS) and SPF. The aim of this article is prospectively to compare the subjective patient discomfort of SPF (Nasopore Forte plu...

The common problems encountered in the surgery for chronic otitis media and chronic paranasal sinusitis were discussed in this articles. "Preservation of the mucous membrane" , "Communication of these cavities with the proper nasal cavity or with the external auditory meatus", and " Obstruction of these cavities" As the result the author has been lead to conclude that it is unnecessary to remov...

M.AH, female, 54 years, born and raised in São Paulo, with repetition epistaxis, nasal obstruction and hyposmia for two years. A solid tumor was found in her nose, coming from the middle meatus and partially obstructing her left nasal cavity. We performed a contrasted CT scan of her paranasal sinuses and a nasofibroscopy with biopsy. The material was then sent for a pathology exam and immunohis...

The present study examined the clinico-pathological profile of sinonasal masses in patients attending an Ear Nose Throat clinic of a rural tertiary care hospital of western Maharashtra in India, between May 2007 to June 2009. During the study period, 112 patients presented with sinonasal masses (male 68, female 44; age group 8-70 years). Nasal polyploid masses were non-neoplastic in 80 (71.4%) ...
