What is the outlook after the surgery?
FESS is highly successful at improving the symptoms of sufferers of chronic sinusitis, but it may not offer a permanent, complete cure because the mucus drainage mechanism has already been badly damaged by the infection. Artificially-created pathways never work as well as natural ones, but are better than none at all. For this reason, even after successful surgery, the patient will be more prone to bouts of sinus trouble than the average person, but usually this will still be better than if they had never had their sinus operation. Most often, even if sinusitis recurs in somebody who has had FESS, it can be brought under control medically (rather than surgically) using various antibiotics, sprays/drops, decongestants or anti-inflammatory steroids. Overall, most patients who undergo FESS, although not completely cured, are a lot better.
