Sinusitis can be categorized into acute sinusitis and chronic sinusitis according to the duration of the disease. Most sinusitis can be eradicated after standardized medication or surgery. 1. Acute sinusitis: treatment methods include medication and surgery. (1) drug treatment: antibiotic drugs preferred amoxicillin clavulanate potassium, the course of 7-14 days; mucosal drainage agents such as eucalyptus pinocchio intestinal soft capsule, etc.; nasal glucocorticosteroid nasal spray treatment: for example, mometasone furoate nasal spray and so on. If the nasal congestion is heavy, it can be combined with nasal decongestant. (2) Surgical treatment: acute sinusitis can be considered for maxillary sinus puncture, sinus balloon dilation and other surgical treatment. 2. Chronic sinusitis: treatment methods include medication and surgery. (1) Drug therapy: the first choice recommended nasal glucocorticoid, such as mometasone furoate nasal spray or fluticasone propionate nasal spray, etc.; macrolide antibiotics: such as roxithromycin, etc.; mucosal drainage agents, such as eucalyptus-pinocampus intestinal capsules and so on. The course of treatment is 8-12 weeks. (2) Surgical treatment: If the combination of nasal anatomical abnormalities, such as deviated nasal septum, vesicular middle turbinate, nasal polyps, etc., conservative treatment is ineffective, then functional nasal endoscopic surgery is recommended. If the diagnosis of sinusitis is confirmed, it is recommended to consult the doctor in time, standardize the treatment under the doctor’s guidance, actively cooperate with the treatment, and follow the doctor’s instructions for medication.
