Treatments for chronic sinusitis include:
Antibiotics are sometimes necessary for sinusitis if you have a bacterial infection. If your doctor can’t rule out an underlying infection, he or she might recommend an antibiotic, sometimes with other medications.
If allergies are contributing to your sinusitis, allergy shots (immunotherapy) that help reduce the body’s reaction to specific allergens might improve the condition.
In cases resistant to treatment or medication, endoscopic sinus surgery might be an option. For this procedure, the doctor uses a thin, flexible tube with an attached light (endoscope) to explore your sinus passages.
Depending on the source of obstruction, the doctor might use various instruments to remove tissue or shave away a polyp that’s causing a nasal blockage. Enlarging a narrow sinus opening also may be an option to promote drainage.
