Sinusitis, which we now clinically refer to as sinusitis. When sinusitis acutely flares up, our main treatment is to administer anti-infection medications and corticosteroid drugs. This includes oral medication treatment or intravenous infusion therapy. Clinically, our main approach is the aforementioned medication treatment, and we also conduct CT scans and surgical treatments based on the patient's condition, of course, assessing symptoms before proceeding. Before surgery, preoperative medication preparation is also needed, which involves some infusion therapy, using these medications, including cephalosporin antibiotics and corticosteroid drugs. (The use of medications should be carried out under the guidance of a professional doctor.)
