Adult sinusitis refers to inflammation of the mucous membrane of the sinus cavity and sinus cavity due to various causes, mainly infectious sinusitis, fungal sinusitis, and allergic sinusitis, etc. Clinically, it mainly manifests as nasal congestion, purulent nasal discharge, odor of the nasal cavity, and decreased sense of smell and headache. In the case of acute infectious sinusitis and acute suppurative sinusitis, patients often have systemic symptoms such as chills and fever, and occasionally cheek pain and tooth root soreness, which are mainly caused by purulent secretions from the sinus cavity stimulating the soft tissues of the cheek and tooth roots. Clinical acute symptoms are mainly treated by anti-infection to control its inflammation; for chronic recurrent sinusitis, it is necessary to consider whether to perform surgical treatment.
