Evolution of guidelines for pediatric rhinosinusitis.

Rhinosinusitis is a prevalent disorder in the pediatric population. Unfortunately, during the past two decades, guidelines related to definitions, diagnostic procedures and management have been much more focused on adult than on pediatric rhinosinusitis. First consensus document on management of pediatric rhinosinusitis was published in 1998, followed by several documents related only to acute rhinosinusitis. The most extensive consensus document on rhinosinuistis, including pediatric rhinosinusitis, is European position paper on rhinosinusitis and nasal polyps, EPOS, updated in 2012.
