About the Procedure
After endoscopic sinus surgery, the lining of the nose and sinuses heals over several weeks. During this time, crusts, dried mucus, small blood clots, and debris naturally form in the surgical areas. Postoperative sinus debridement is a gentle, in-office procedure in which the surgeon uses an endoscope to look inside the nose and remove this material so that the sinuses can heal in an open, well-ventilated position.
Debridement is part of recovery rather than a separate operation. Clearing crusts and debris helps prevent them from blocking the newly opened drainage pathways, reduces the chance of scar tissue forming, and lets the surgeon check on healing. The number of visits varies from person to person.
At Norelle Health, debridement visits are tailored to how each person is healing. Some people need only a visit or two, while others, particularly after more extensive surgery or with polyps, benefit from a few visits over the first weeks.
What debridement is
Debridement is a gentle cleaning of the nose and sinuses after surgery, done in the office with an endoscope for visualization. The surgeon removes crusts, dried mucus, small clots, and debris from the surgical areas and may remove early scar tissue if it is forming.
It is not a second operation. It is a normal, expected part of recovery that helps the sinuses heal in an open position and lets the surgeon monitor progress.

Why crusts and clots form
After surgery, the healing lining produces mucus and small amounts of blood, which dry into crusts and clots along the areas that were operated on. This is a normal part of healing.
If crusts and debris are left to build up, they can block the newly opened sinus drainage pathways, trap mucus, and contribute to scar tissue. Removing them helps keep the pathways open while the lining recovers.

What happens during the visit
A topical decongestant and numbing spray are often applied first to improve comfort and visibility. Using an endoscope, the surgeon examines the nose and sinuses and gently removes crusts, clots, and debris with small instruments or suction.
The visit is usually short. The surgeon also checks how the surgical sites are healing and may adjust your saline rinses or medications based on what is seen.
Comfort measures
Numbing and decongestant sprays help reduce discomfort during debridement. Taking your usual saline rinses beforehand can soften crusts and make cleaning easier and more comfortable.
Most people tolerate the visits well. If you tend to feel anxious or sensitive, let the team know so that extra time and additional comfort measures can be used.
How many visits may be needed
The number of debridement visits varies. Some people need only one or two, while others, especially after more extensive surgery or surgery for nasal polyps, benefit from several visits over the first few weeks.
The schedule is individualized based on how you are healing. The goal is to keep the sinuses open and clear until the lining has recovered, then space visits out as healing allows.

When symptoms are not routine
Some congestion, light bleeding, crusting, and pressure are expected during recovery and tend to improve over time. However, certain symptoms are not routine and should prompt a call to the office or urgent care.
These include heavy or persistent bleeding, high fever, increasing facial pain or swelling, vision changes or double vision, severe headache with a stiff neck, or a clear, watery nasal drainage that is constant. These can signal a problem that needs prompt attention.
