Nasal Polyposis: Diagnosis and Treatment

Nasal polyposis is a chronic inflammatory disease of the nasal and paranasal sinuses mucosa, characterized by prolapse of edematous mucosa as grey polypoid masses, most commonly from the anterior ethmoid region. Nasal polyps are common, affecting up to 1-4 percent of the population. They present with nasal obstruction, rhinorrhoea, post nasal drip, loss of sense of smell, and less commonly facial pain. The management of nasal polyps, aimed at improving these symptoms, includes both surgical and medical treatments, but there is no universally accepted management protocol. Several hypotheses have been put forward regarding the underlying mechanisms but the aetiology is still unknown. In this article, we present the recent advances in the diagnosis and treatment of nasal polyposis by reviewing new guidelines and meta-analysis studies
