The differentiation between chronic simple rhinitis and chronic hypertrophic rhinitis is as follows: 1. Chronic simple rhinitis: nasal congestion is characterized by intermittent and alternating nasal congestion, nasal discharge is usually mucus discharge, secondary to infection there may be pus discharge and hypertrophy of the inferior turbinates. It is sensitive to the contraction of decongestants, and the treatment methods are mainly intranasal decongestants, intranasal glucocorticoids, and nasal irrigation, etc. 2. Chronic hypertrophic rhinitis: the main clinical characteristics are unilateral or bilateral persistent nasal congestion without alternation, mucus or mucopurulent nasal discharge, not easy to blow, and inferior turbinate hypertrophy, which is not sensitive to decongestants. The treatment method is conservative treatment, and when it is ineffective, surgical treatment can be used, and the surgical methods include partial mucosal resection of inferior turbinate and submucosal resection of inferior turbinate.
