Functional endoscopic sinus surgery (FESS)

Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical procedure for severe sinus diseases. Nasal endoscopes, with lights and lenses, are used by ENT surgeons to treat sinus pain without any cut or incision.
If you have persistent sinus inflammation or a chronic sinus infection that does not respond to traditional therapies such as antibiotics and allergy medicines, your doctor may advise for FESS. Most people resume their regular routines around two weeks after FESS.
