FESS FAQs

(Functional Endoscopic Sinus Surgery)

What is FESS?

Functional Endoscopic Sinus Surgery is a minimally invasive procedure used to improve sinus drainage and ventilation. Surgeons use small endoscopes inserted through the nostrils—meaning no external incisions—to open blocked sinus pathways.

How long does the procedure take?

The length varies depending on the complexity of the sinus disease. Many procedures take between 1–3 hours, but this can differ from person to person.

How much time does it take to recover after a FESS procedure?

Recovery time varies with each patient. People often return to normal activities gradually over several days. A specialist typically provides guidance on:

  • Activity restrictions
  • Nasal care
  • Follow‑up visits

Is a FESS procedure successful?

Many people experience significant improvement in symptoms after surgery. Success depends on factors such as underlying conditions, anatomy, and adherence to postoperative care.

Are there any risks associated with a FESS procedure?

As with any medical procedure, potential risks and complications do exist. 

Possible side effects include, but are not limited to, post-operative bleeding; pain and swelling; allergic reaction to anesthesia or other medications administered during the procedure; or infection. There is also a small risk of mucosal/tissue damage from the expansion.

Make sure to schedule a consultation with us to determine if your specific condition or anatomy may present any special risks.

Will I be awake during the FESS procedure?

Most FESS procedures are done under general anesthesia, though the exact approach depends on the surgeon and the patient’s needs and varies from patient to patient.

Will my insurance or Medicare cover a FESS procedure?

Most insurance companies and Medicare cover Functional Endoscopic Sinus Surgery (FESS) if considered medically reasonable and necessary. To be certain of your level of insurance coverage, contact your insurance provider to find out your specific policy.
