When Should You Consider Sinus Surgery?
Most people with sinus problems never need surgery. Nasal sprays, antibiotics, saline rinses, and allergy management sort out the majority of cases reasonably well. But for a subset of patients, these measures simply do not hold. The infections keep coming back. The congestion never fully clears. The facial pressure becomes a constant. At some point, the conversation shifts from medication to whether sinus surgery is the right next step.
Knowing when that point has genuinely been reached is important. Surgery should follow a proper trial of medical treatment, not precede it. But equally, continuing to cycle through antibiotics and sprays when surgery would provide lasting relief is its own problem.
What medical treatment actually needs to look like first
Sinus surgery should only be considered when medical therapies have failed to improve a patient's symptoms and quality of life. That means a genuine, adequate course of treatment, not just a week of antibiotics or a nasal spray used inconsistently for a month.
A proper trial of medical therapy for chronic sinusitis typically includes nasal corticosteroid sprays used regularly for several weeks, saline nasal irrigation, antihistamines where allergies are contributing, and in some cases a prolonged course of antibiotics or a short course of oral steroids. If symptoms persist despite all of this, and CT imaging confirms ongoing disease in the sinuses, then surgery becomes a legitimate option.
The most common reasons sinus surgery is recommended
- Chronic sinusitis that does not respond to medication
The most common indication for functional endoscopic sinus surgery is chronic sinus problems that do not respond to medical treatments. The diagnosis of chronic sinusitis is based on symptoms, nasal examination, sinus CT findings, and response to previous treatments.
Chronic sinusitis means symptoms lasting more than 12 weeks. When those symptoms persist despite adequate medical management, and CT imaging shows persistent disease, surgery is considered a reasonable next step.
- Nasal polyps
Nasal polyps are soft, non-cancerous growths that develop inside the sinuses and nasal passages. They block drainage, obstruct airflow, and reduce how well nasal sprays penetrate the affected areas. Nasal polyps can interfere with medical therapy and obstruct airflow, and often require nasal polyps surgery when they are significant enough to prevent medication from reaching the sinus lining effectively.
Surgery removes the polyps and opens the sinus cavities, allowing medication to work properly afterward. Polyps do tend to recur, which is why post-surgical medical management remains important.
- Recurrent acute sinusitis
Functional endoscopic sinus surgery is a minimally invasive technique used to treat medically refractory chronic sinusitis with or without polyps, and recurrent acute sinusitis. For patients who experience four or more discrete sinus infections a year despite appropriate treatment between episodes, surgery to improve sinus drainage reduces the frequency of these recurrences.
- Structural problems blocking drainage
A deviated nasal septum, enlarged turbinates, or narrow sinus openings can physically prevent the sinuses from draining, regardless of how well the medical side of things is managed. When anatomy is the primary driver of the problem, no amount of medication corrects it. Surgical correction of the underlying structural issue is the only way to address it properly.
- Suspected tumour or complications
Sinus surgery is considered necessary when a suspected tumour is seen on imaging, physical examination, or endoscopy, or when suppurative complications are present. These situations are less common but represent straightforward surgical indications where delay carries real risk.
What functional endoscopic sinus surgery involves
Functional endoscopic sinus surgery is a minimally invasive approach to the sinus cavities using endoscopes to view the important structures of the nose and sinuses. The view with the endoscope allows for better identification of the underlying disease, which enables the surgeon to be precise and thorough with minimal damage to normal surrounding tissue.
The procedure is performed entirely through the nostrils. There are no external cuts and no visible scarring. All four sets of sinuses can be assessed and treated during a single procedure where needed. Recovery is generally manageable and most patients are able to return to normal activities within one to two weeks.
Balloon sinuplasty provides an alternative for those with less severe illness. A small balloon is used to gently open up clogged sinus openings, without destroying tissue. This makes it acceptable for milder instances that have not responded to therapy, but do not include major polyps or structural abnormalities.
What surgery can and cannot achieve
Functional endoscopic sinus surgery is not a cure for sinusitis, but it is helpful in managing symptoms of the chronic nature of the disease. With proper patient selection, it has been shown to be 70 to 90 percent successful in improving symptoms.
Surgery improves drainage and removes obstruction. It does not change the underlying tendency of the sinuses to become inflamed. Post-surgical medical management, including nasal sprays, saline rinses and allergy treatment where relevant, remains important for maintaining the results.
Takeaways
If medications have been tried and have failed to provide adequate relief for chronic sinusitis, sinus surgery is the next reasonable approach. Indications for functional endoscopic sinus surgery include chronic sinusitis unresponsive to medical treatment, large nasal polyps that block drainage, recurrent acute sinusitis and anatomical deformities that affect normal sinus drainage.
Surgery improves drainage and symptom management in most suitably selected patients. Anyone thinking about sinus surgery should be seen by an ENT expert who may study his or her imaging, inspect the nasal passages, and confirm that medicinal care has been sufficiently attempted prior to proposing a surgical approach.
