Pus in the sinuses is usually treated with conservative medication, nasal irrigation, and surgical puncture to drain the pus. 1. Medications: Use antibiotics such as Roxithromycin to control the infection and minimize complications under the guidance of a doctor, or use Oronema drops orally to promote the discharge and absorption of pus. 2. Nasal rinsing: choose professional nasal washers, use saline with hormones, for adequate nasal cleansing. 3. Puncture pus discharge: when the pus is more or cannot be discharged through conservative treatment, a puncture stoma can be made in a suitable place to facilitate the discharge of pus from the sinuses. Patients should go to the hospital as soon as possible after finding pus in the sinuses, so as to clarify the cause of the disease and improve the relevant diagnosis and treatment under the guidance of physicians.
