Sinusitis does not necessarily require surgery; in some cases, medication treatment can be considered. This approach mainly depends on the severity of the sinusitis and the patient's overall symptoms. Especially for acute sinusitis or cases of mild chronic sinusitis, medication is generally the first choice. Furthermore, most patients can effectively alleviate symptoms and improve their condition through standardized medical treatment. The main treatments are oral medications and nasal sprays, and it is also advisable to consider cleansing the nasal cavity with saline solution followed by regular check-ups. In cases of fungal sinusitis or severe inflammatory reactions in chronic sinusitis, surgery might be considered. Generally, surgery is a common minimally invasive procedure with good outcomes.
