FESS, or Functional Endoscopic Sinus Surgery, is a minimally invasive surgery in which the surgeon uses nasal endoscopes to increase the size of the nasal drainage pathways of the paranasal sinuses to improve sinus ventilation. It is the most effective treatment for sinusitis.
Sinusitis is the inflammation of the tissue lining of the sinuses. Healthy sinuses are pneumatic, i.e., they are filled with air and responsible for humidifying and warming the inspired air. On the other hand, if sinuses are infected, they are filled with mucus and bacteria, which causes nasal congestion, inflammation, etc., which makes breathing difficult.
When sinuses are too congested and are not responding to medicines, then surgical intervention becomes necessary to drain the sinuses and make breathing easier. If you have severe sinusitis and want to get long-term relief from your symptoms, book an appointment with the best ENT specialists in Chennai for sinusitis treatment near you.

One of the most important criteria for diagnosing sinusitis is a medical history and physical examination. Your doctor will collect a detailed medical history, along with your symptoms, their severity, duration, recurrence, etc., to determine whether you have acute or chronic sinusitis.
Other diagnostic tests that help diagnose the presence and severity of sinusitis are:

In contrast to conventional surgery, FESS is less invasive and promises better recovery with minimal scarring. It is usually performed under local anesthesia. The surgical instruments are inserted through the nose to preserve aesthetic appearance. The infected sinuses are located, drained and then washed using a saline solution. After all the infected tissue is removed, the incisions are closed.

Yes. One of the rare complications of sinus surgery is further sinus obstruction to adhesion of the sinus. In such a case, a revision sinus surgery is performed to clear the air pathways and provide better results than the initial sinus surgery.
FESS is performed under either general or local anesthesia, as such, the surgery is not painful. However, depending on the extent of the sinus infection, there may be mild to moderate pain after the surgery that generally feels like a blocked sinus. Pain after sinus surgery lasts for about a week and is managed through over-the-counter pain medications and anti-inflammatories.
Generally, a FESS procedure lasts for about 2-2.5 hours, although this time range can vary a lot depending on which sinuses are infected and how much the infection has spread.
Sinus issues can be very persistent, i.e., they can easily return even after sinus surgery, however, their recurrence rates are highly variable and depend on the patient themselves. According to research conducted by BMC (BioMed Central), the recurrence rates for sinusitis after FESS ranges from 4% to 60%, with a median of 20% over a two-year period.
