The treatment of sinusitis is currently divided into two main categories: conservative treatment and surgical treatment. The specific choice of treatment mainly depends on the severity and type of sinusitis. For fungal sinusitis, conservative treatment generally does not yield good results. If the patient's condition permits and their physical health can tolerate surgery, it is generally recommended to perform sinus opening surgery under endoscopy. For bacterial sinusitis with mild inflammation, unclear symptoms, or relatively mild symptoms, conservative drug treatment can be considered. This usually involves oral medications and nasal sprays, and saline nasal irrigation can also be considered. If the inflammatory response is more severe and the symptoms are typical, and conservative treatment is ineffective, sinus opening surgery should be considered. Currently, minimally invasive surgery under endoscopy is employed, which generally yields precise results, causes less damage, and allows for a quicker recovery.
