Endoscopic Sinus Surgery

Endoscopic sinus surgery is a closed, minimally invasive technique that treats chronic and recurrent sinus disease by reopening the narrow passages through which the sinuses normally drain. A thin, rigid endoscope carrying a camera and a light is passed through the nostril, giving the surgeon a clear, magnified view of the inside of the nose and the sinus openings on a screen. Working only through this natural route, the surgeon removes diseased tissue, polyps and the structures that block drainage, while preserving as much healthy lining as possible. Because nothing is cut on the outside of the face, there is no visible scar, recovery tends to be quicker than with older open techniques, and the risk of complications is lower. The goal is to restore the sinuses' own ventilation and drainage rather than simply to clear an infection.

Endoscopic sinus surgery is considered when sinus problems are persistent, keep coming back and no longer respond to medication, sprays and rinses, and when they clearly lower quality of life. The most common reason is chronic sinusitis, meaning inflammation that lasts longer than about twelve weeks despite proper treatment, often with facial pressure, a blocked nose, thick discharge and a dull, constant headache. Other clear indications include nasal polyps that block the nose and dull the sense of smell, anatomical blockages that stop the sinuses draining, fungal sinus infections, and repeated acute infections that return as soon as antibiotics stop. It is also used to take a sample of or remove abnormal tissue and other masses within the sinuses. The aim throughout is to open the natural drainage path, improve airflow and calm the underlying inflammation.

The operation is usually carried out under general anaesthesia, with local anaesthesia and sedation reserved for limited cases. The surgeon places the slim, lighted endoscope into the nostril and views the nasal cavity and sinus openings directly on a screen, then works through this natural opening with fine instruments. Narrowed or blocked drainage channels are gently widened, polyps and diseased tissue are removed, and any structure disrupting drainage is corrected, all with minimal damage to the surrounding healthy lining. The extent of surgery is tailored to the cause, whether that is chronic inflammation, polyps or an anatomical blockage, and a deviated septum or enlarged turbinates can be addressed in the same sitting when they contribute to the problem. Light, dissolvable dressings or soft packing are sometimes placed at the end. A typical procedure takes about 1 to 2 hours.

A good candidate has chronic or recurrent sinus disease confirmed on examination and imaging, has given medical treatment a fair trial without lasting relief, and is in general good health. The method can be applied in adults and, when needed, in children, with the extent always planned individually. Assessment combines a nasal endoscopy to look directly at the sinus openings with a computed tomography scan that maps the sinuses in detail, alongside a review of allergies, asthma, previous surgery and overall health. Before surgery, routine checks confirm fitness for anaesthesia, and blood-thinning medicines, certain supplements and smoking are paused in advance on medical advice to reduce bleeding and aid healing. For international patients, much of this can begin remotely, with existing scans and a symptom questionnaire reviewed before travel and the endoscopic examination completed on arrival.

Most patients go home the same day or after one night and feel congested, with mild oozing for the first day or two rather than severe pain, which is easily controlled with simple painkillers. Saline rinses are started early and are central to recovery, as they clear crusting and keep the newly opened channels draining while the lining heals. Light daily activity resumes within a few days, while heavy exertion, nose blowing and swimming are avoided for a few weeks. Planning a trip abroad, it is sensible to stay in the destination city for about 5 to 7 days so that any packing can be removed and early healing checked, often including a gentle cleaning of the nose, before flying. Air travel is generally comfortable once that check confirms healing is on track. Afterwards, follow-up continues remotely by message, photo or video, and international patient teams routinely provide interpreters and coordinators so that language is never a barrier.

When performed by an experienced surgeon in a proper hospital setting, endoscopic sinus surgery is a safe and well-established operation, though like any surgery it carries some risk. Early effects such as congestion, mild bleeding, crusting and a temporary change in smell are expected and settle as the lining heals. Less common risks include infection, bleeding that needs attention, and, rarely, injury to nearby structures, because the sinuses lie close to the eye and the base of the skull, which is exactly why the magnified endoscopic view and careful technique matter so much. In some people, especially those with extensive polyps, the disease can return over time and may need ongoing medical treatment or a further procedure. Choosing a qualified surgeon, allowing enough time before flying and keeping up the saline rinses are the keys to a safe experience and a lasting result, and most patients enjoy clearer breathing, less pressure and fewer infections.
