The sinuses are connected to the nose through very small openings. Inflammation of the nose can cause these to swell shut leading to back up of mucous, infection, and all of the symptoms that we associate with sinusitis. In people without chronic sinus disease, these openings are large enough to allow drainage even when inflamed, but in the unlucky patients dealing with chronic sinusitis or recurrent sinusitis, these openings are just too narrow. Expanding the natural sinus drainage pathways is the basis for all modern sinus
surgery.
Modern sinus surgery is divided into two categories: traditional, large opening sinus surgery and balloon sinuplasty. Both of these sinus surgeries are aimed at opening the small natural openings from the sinuses into the nose. This is done in different ways, but both are very effective. The difference comes down to the extent of surgery and size of the opening at the end of surgery. Both have benefits and drawbacks to be considered and discussed with your surgeon.
