A polyp is an oedematous mucous membrane which forms a pedunculating process with a slim or broad stalk or base. Nasal polyps originate in the upper part of the nose around the openings to the ethmoidal sinuses. The polyps extend into the nasal cavity from the middle meatus, resulting in nasal blockage and restricted airflow to the olfactory region. The polyp stroma is highly oedematous with a ...
BACKGROUND The objective of this work was to review the literature concerning the distribution of topical therapeutics to the sinuses versus nasal cavity regarding: surgical state, delivery device, head position, and nasal anatomy and to provide evidence-based recommendations. METHODS A systematic review was conducted using Medline, EMBASE, and Cochrane databases to perform a Medical Subject ...
INTRODUCTION Metastatic disease in the sinonasal region occurs rarely and the primary site may be elusive. This case highlights the possibility of an occult renal tumor manifesting with nasal symptoms and the risk of severe bleeding following nasal biopsy. CASE PRESENTATION We report the case of a 79-year-old Caucasian woman who presented with a six-week history of intermittent left-sided nos...
BACKGROUND Staphylococcus aureus secretes numerous exotoxins which may exhibit superantigenic properties. Whereas the virulence of several of them is well documented, their exact biological effects are not fully understood. Exotoxins may influence the immune and inflammatory state of various organs, including the sinonasal mucosa: their possible involvement in chronic rhinosinusitis has been su...
BACKGROUND In primary care and epidemiological studies of chronic rhinosinusitis (CRS), symptom-based diagnosis is common, yet limited, because endoscopic and radiological signs are not considered. OBJECTIVES To evaluate the correlation between symptoms and objective findings of CRS to improve its symptom-based diagnosis for primary care and epidemiological studies by using data from a large-...
BACKGROUND Intranasal steroids are the first line of treatment for chronic rhinosinusitis. Although contamination of adjunctive devices (e.g. irrigation bottles) has been much investigated, little is known about nasal contamination of the metered-dose spray bottles used to deliver intranasal steroids, and the potential influence on disease chronicity. METHODS Twenty-five prospectively recruit...
