Endoscopic & Debrider-Assisted Sinus Surgery
Minimally invasive relief for long-standing sinus trouble, done entirely through the nostrils
If sinus infections, a constantly blocked nose or nasal polyps have not settled with medicines, keyhole sinus surgery may be an option worth discussing. It is performed entirely through the nostrils, so there are no cuts on your face. At Abhinav’s ENT Care Center in Hastinapuram, Hyderabad, Dr. G Abhinav Kumar Reddy assesses each patient carefully before advising whether this procedure is right for you.
What is Endoscopic Sinus Surgery?
Functional Endoscopic Sinus Surgery, usually shortened to FESS, is a minimally invasive operation used to treat ongoing sinus problems. The word “endoscopic” means it is done with an endoscope, a thin telescope with a light and camera that lets the surgeon see clearly inside the nose. Everything is carried out through the nostrils, so there are no external or facial incisions (cuts).
Your sinuses are air-filled spaces in the bones around your nose. They drain into the nose through small natural openings. When these openings become swollen or blocked, mucus gets trapped, which can lead to repeated infections, pressure and a blocked nose. The aim of FESS is to gently clear the diseased tissue and reopen these natural drainage pathways, so your sinuses can drain and breathe normally again.
To do this precisely, the surgeon often uses a powered microdebrider. This is a fine instrument that carefully removes diseased tissue and nasal polyps (soft, non-cancerous swellings in the nose) while sparing the healthy tissue around them. Because it is tissue-sparing and controlled, it allows delicate, accurate work in a small space.
FESS is usually planned as a day-care or short-stay procedure and is performed under anaesthesia. Whether it suits you depends on your symptoms, your scan findings and your overall health, which Dr. Abhinav will discuss with you in person before recommending surgery.
Why this approach is used
For suitable patients, keyhole sinus surgery offers several practical advantages over older, more open operations.
No cuts on the face
The entire procedure is done through the nostrils, so there are no external scars.
Minimally invasive
Working through natural openings generally means less trauma to surrounding tissue.
Precise, tissue-sparing removal
The microdebrider removes diseased tissue and polyps while protecting healthy lining.
Often day-care
Many patients can go home the same day or after a short stay, once the doctor is satisfied.
Restores natural drainage
Reopening blocked sinus pathways helps the sinuses drain and ventilate the way they should.
What the procedure involves
Here are the key features that make up endoscopic, debrider-assisted sinus surgery.
- Endoscopic visualisation
- A thin telescope with a camera gives a clear, magnified view inside the nose and sinuses.
- No external incisions
- All work is done through the nostrils, avoiding cuts on the face or gums.
- Powered microdebrider
- A precise instrument that gently shaves away diseased tissue and polyps while sparing healthy lining.
- Reopening drainage pathways
- The natural openings of the blocked sinuses are cleared so mucus can drain freely.
- Performed under anaesthesia
- The procedure is carried out under anaesthesia so you are comfortable throughout.
- Day-care or short stay
- Depending on your case, it is often planned as a same-day or short overnight procedure.
- Individually planned
- The exact extent of surgery is tailored to your symptoms and CT scan findings.
Conditions it can help treat
Endoscopic sinus surgery is generally considered when appropriate medical treatment has not brought enough relief. It may be advised for:
- Chronic rhinosinusitis (long-standing inflammation of the nose and sinuses)
- Nasal polyps (soft swellings in the nasal lining causing blockage)
- Recurrent sinus infections that keep coming back despite medicines
- Sinusitis not responding adequately to medical treatment
- Fungal sinusitis
- Certain structural blockages affecting sinus drainage
- Persistent nasal congestion and sinus pressure linked to blocked drainage pathways
What to expect
Consultation and assessment
Dr. Abhinav reviews your symptoms and history, examines your nose, often with an endoscope, and may advise a CT scan to plan treatment. Surgery is only recommended if it is the right step for you.
Preparing for surgery
If you decide to go ahead, you will be guided on pre-operative checks, which medicines to pause and simple instructions such as fasting before anaesthesia.
The procedure
The surgery is done through the nostrils under anaesthesia using an endoscope and microdebrider. Diseased tissue and polyps are removed and blocked sinus openings are reopened.
Recovery and going home
This is often a day-care or short-stay procedure. You may have some congestion and mild discomfort initially, and you will be observed before being discharged with clear instructions.
Follow-up cleaning
Follow-up visits allow gentle cleaning of the nose and monitoring of healing, which is an important part of getting a good result.
What the surgery may include
FESS is not one fixed operation. Which sinuses are opened depends on where the disease actually is on your CT scan, so two people having "sinus surgery" may have quite different procedures. These are the steps most often involved — Dr. Abhinav will explain which apply in your case, and why, before you decide anything.
Maxillary antrostomy
Widening the natural opening of the maxillary sinus, the large sinus in the cheek. This is one of the most commonly needed steps, as this sinus blocks easily.
Ethmoidectomy
Clearing the ethmoid air cells — a honeycomb of small sinuses between the eyes. These are often the first to become diseased in chronic sinusitis and in nasal polyps.
Sphenoidotomy
Opening the sphenoid sinus, which sits deepest, behind the nose. It is opened when disease has reached that far back, and can be a cause of pain felt behind the eyes or at the back of the head.
Frontal sinusotomy
Clearing the drainage pathway of the frontal sinus, above the eyebrows. This is the narrowest and most delicate pathway to work in, and is opened only when it is genuinely involved.
Septoplasty, if needed
Straightening a deviated septum — the partition between the nostrils. This is sometimes done at the same sitting, both to relieve blockage and because a badly deviated septum can physically prevent access to the sinuses.
Turbinate reduction, if needed
Reducing an enlarged turbinate, one of the ridges inside the nose that warm and humidify air. Done only where enlargement is itself contributing to the blockage; the turbinate is reduced, not removed, because it has a real job to do.
Risks and possible complications
Endoscopic sinus surgery is generally a safe, well-established procedure, and serious problems are uncommon. But no operation is without risk, and you should know what those risks are before agreeing to one. They are set out honestly here rather than left for the consent form.
Common, and usually settle on their own
- Blocked or congested nose for the first days to weeks while the lining heals
- Blood-tinged discharge and crusting inside the nose
- Mild discomfort, facial pressure or headache
- A temporarily reduced or altered sense of smell
Less common
- Bleeding heavy enough to need packing or another procedure
- Infection needing further antibiotics
- Adhesions — scar bands forming inside the nose, which may need to be divided at a follow-up visit
- Polyps or inflammation returning over time, sometimes needing revision surgery
- Persistence of some symptoms, as surgery restores drainage but does not cure the underlying tendency to inflammation
Rare, but serious — and the reason this is done under endoscopic vision
- Injury near the eye socket, which sits directly beside the sinuses: bruising, and very rarely double vision or a change in vision
- A cerebrospinal fluid leak — a leak of the fluid surrounding the brain, because the roof of the sinuses forms part of the skull base. It may need repair
- Damage to the tear duct, causing a watery eye
- Risks associated with anaesthesia itself
How likely any of these are depends on your own anatomy, how extensive the disease is and which sinuses need opening — which is exactly why no honest figure can be quoted on a webpage. Dr. Abhinav will go through the risks that genuinely apply to your case, in person, before you decide. If surgery is not clearly the right step for you, he will say so.
Recovery and aftercare
It is normal to have some nasal congestion, mild discomfort and a little blood-tinged discharge in the first few days after surgery. This usually settles gradually. Your sense of smell and clear breathing may take a little time to improve as the inside of the nose heals.
Healing is helped a great deal by following your aftercare instructions and attending your follow-up appointments. During these visits, the nose may be gently cleaned to remove crusts and to help the sinuses heal well. Recovery times vary from person to person, so Dr. Abhinav will guide you on what is right for your situation.
Saline nasal rinses
Use salt-water rinses as advised to keep the nose clean and comfortable.
Take medicines as prescribed
Complete any antibiotics, sprays or other medicines exactly as instructed.
Rest and avoid strain
Avoid heavy lifting, strenuous activity and forceful nose-blowing while you heal.
Attend follow-up visits
Come for scheduled cleaning and reviews, as these are key to a good recovery.
