Functional endoscopic sinus surgery, or FESS, is done to treat chronic sinus infections. The surgeon uses small instruments to go through the nose and open the sinuses. This allows the sinuses to drain so there will be fewer infections.
Your child should rest at home for the first 24 hours after surgery. He or she may become more active when feeling better. Usually a child may return to school one to two days following a functional endoscopic sinus surgery. He or she should not take gym or do any heavy exercise such as bike riding, swimming or other sports activity until approved by the doctor.
