Clinical efficacy of intranasal drug delivery by nebulization in chronic rhinosinusitis: a systematic review.

Treatment of chronic rhinosinusitis (CRS) aims to treat the underlying inflammation or infection. Although the optimal modality of administration remains controversial, inhalation route is usually preferred. The aim of this systematic review was to summarize the efficacy of intranasal corticoisteroids or antibiotics delivery by nebulization on symptoms, histology, endoscopy scores, nasal obstruction, clinical outcomes and quality of life in CRS.
