For the initial onset of sinusitis and nasal polyps, the symptoms can be effectively controlled by pharmacological treatment, mainly with antimicrobials, mucus promoters and short-term nasal vasoconstrictors. At the same time, glucocorticoid nasal sprays are applied, which can play an anti-inflammatory and anti-allergic role and also promote the recovery of the mucous membrane of the nasal cavity and sinuses. For patients with chronic sinusitis with nasal polyps who do not respond well to medication, surgery is the best option and is performed via nasal endoscopy under general anesthesia. This way the polyps are removed more thoroughly and also promotes the ventilation and drainage of the sinuses. After surgery, regular follow-up and nasal medication must be performed, and saline rinses should be used to facilitate the flow of dry crusts from the nasal cavity to avoid blocking the sinuses again and inducing nasal polyps, which can lead to recurrence within a short period.
