The treatment of sinusitis is mainly divided into three categories. The first category is observation and follow-up; the second category is medication treatment; the third is surgical treatment. If the sinusitis is very mild and does not have obvious clinical symptoms, and the nasal cavity is relatively clean, most of these cases can be considered for observation without particular treatment. If the inflammation is more pronounced, accompanied by nasal congestion, a runny nose, headache, and dizziness, most of these cases should consider medication treatment, which usually involves oral medications and nasal sprays. Additionally, rinsing the nasal cavity with saline can be considered. If the inflammatory response is particularly severe and symptoms are pronounced, and if standard medication treatment is ineffective, surgery may need to be considered. Currently, the main surgical option is endoscopic sinus surgery. Generally, this approach is quite effective, causes less damage, and allows for a relatively quick recovery.
