No matter how excellent a job we do, the condition is not cured. But if we don't do the surgery the patient will be worse off. Usually we can give the patient the statistics as to the benefits of the surgery. Sometimes we only go to open the sinus openings that have closed. Sometimes, we must enter the sinus cavity and remove diseased tissue.
Today telescopes through the nose perform much of the surgery.
Most doctors use the techniques shown to be most effective. In some cases we like to use Insta Trak , a method of displaying the sinuses in 3 dimensions and showing the location of the instruments at all times. You can ask your family doctor about this doctor's reputation, what hospital staff he is a member of, and so on. Surgery is done for sinus problems in other countries at a far greater rate than here. They may not have the luxury of frequent office visits, long term antibiotics, and so on.
