The treatment of sinusitis is mainly divided into two major categories. The first category is conservative treatment, and the second category is surgical treatment. Most patients consider conservative treatment because it can effectively control the condition and alleviate inflammation, and the overall effect is relatively good. In terms of medication, oral medications are primarily considered, commonly involving the use of antibiotics combined with nasal sprays and traditional Chinese medicine treatments. Additionally, physiological saline or seawater can be considered for nasal irrigation. Generally, the treatment period is about one to two weeks or more, and regular follow-ups are required. If it is fungal sinusitis, or if the effect of drug treatment for chronic sinusitis is not satisfactory, surgery may be considered. The surgery mainly involves minimally invasive sinus surgery under nasal endoscopy, which generally causes less damage and is quite effective.
