Discussion
Full house FESS [Functional Endoscopic Sinus Surgery] is often performed for certain indications. How much will patients benefit in terms of their initial symptoms? Do they return back with persistent headaches?
There are possibilities of poor drainage of secretion perhaps due to inadequate opening of sinus cells. This may cause re-circulation of mucous leading to accumulation of secretions within the sinuses triggering bio-film formation.
Sometimes patient’s with FESS surgeries in the past with persistent symptoms can be offered with other techniques using balloon dilatation and irrigation of the sinus. It will remove biofilms which proves to give improvement in symptoms without further trauma to the nasal lining and structures.
