The treatment for sinusitis primarily involves conservative medication, as well as surgical procedures. Generally, conservative medical treatment is the standard first-line method. In terms of treatment methods, antibacterial therapy is mainly used, along with the oral administration of traditional Chinese medicine preparations, and mucolytic agents, which help alleviate sinus inflammation and facilitate the discharge of secretions from the nasal and sinus cavities. Additionally, nasal irrigation with saline solution can be considered to further improve the condition. If standardized medical treatment is ineffective, or in cases of fungal sinusitis, we may consider conducting minimally invasive sinus surgery using nasal endoscopy. Overall, the outcomes of surgical treatment are usually quite good, but regular follow-up examinations are needed to check for any recurrence of the condition.
