FESS is a minimally invasive surgical technique that uses endoscopic tools to treat complicated acute or chronic sinus infections.
The goal of FESS is to provide wide-open air ventilation throughout the sinuses and enhance sinus drainage. The sinus lining is preserved, not stripped. This will enable restoration of healthy sinus linings.
Your nose will feel congested for 7-10 days. For some, antibiotics are necessary; the sinus cavities should be fully healed in 3-4 weeks.
