Hypertrophic sinusitis requires the severity of the lesion to be clarified based on CT examinations, as well as the time of occurrence of the lesion to choose a different treatment method. For those with a short time of appearance, pharmacological treatment is based on the use of antibiotics of sensitive classes, mainly second-generation cephalosporins and macrolides, such as cefuroxime, roxithromycin, clarithromycin, etc. Combined with mucus pro-drainage agents to promote ventilation and drainage of the nasal cavity and sinuses. Short-term nasal vasoconstrictors, such as furosemide nasal drops, are also needed, with a medication cycle of no more than 7 days. Auxiliary saline rinses of the nasal cavity can clear the nasal secretions and irritants, reduce the edema of the mucosa, and promote further recovery of the mucosal function. For those who are ineffective after medication, or sinusitis is more serious, surgery is recommended. Surgery is usually performed under nasal endoscopy, which is a minimally invasive treatment method, and the purpose is also to open the sinus opening, promote the ventilation and drainage of the nasal cavity and sinuses, and prevent recurrent symptoms.
