Persistent sinus problems can affect breathing, sleep and overall quality of life. When symptoms such as nasal blockage, facial pressure or recurring infections do not improve with medication, further evaluation may be needed. Understanding your options—including sinus surgery—can help you make informed treatment decisions.
This guide provides a comprehensive overview of sinus conditions, including causes, diagnosis, treatment options, surgical procedures, recovery timelines and long-term outcomes. It is designed to support patients seeking effective ENT sinus surgery and long-term relief.
Chronic sinusitis (also known as chronic rhinosinusitis) is a long-term condition where the sinuses remain inflamed and swollen for an extended period, lasting more than 12 weeks despite treatment.
The sinuses are air-filled spaces within the skull that help produce and drain mucus through the nasal passages. When these drainage pathways become blocked, mucus can build up, leading to persistent inflammation and, in some cases, infection.
When chronic sinusitis develops, patients may experience ongoing nasal congestion, facial pressure and difficulty breathing through the nose. This can interfere with daily activities, sleep and overall comfort. Unlike short-term sinus infections, chronic sinusitis tends to persist over time and may require a combination of medical or surgical treatment to manage effectively.
Chronic sinusitis occurs when the lining of the sinuses remains inflamed over time, leading to persistent symptoms.
Common chronic sinusitis causes include:
These factors can interfere with normal drainage, leading to repeated infections, ongoing breathing problems, and nasal symptoms.
Symptoms of chronic sinusitis can vary in severity but are often persistent and may affect daily comfort, sleep and overall quality of life.
Common symptoms include:
In some cases, symptoms may fluctuate but do not completely resolve, which is a key feature of chronic sinusitis.
Accurate chronic sinusitis diagnosis is essential to identify the underlying cause of symptoms and determine the most appropriate treatment approach. A thorough evaluation helps distinguish between persistent inflammation, structural blockage or recurrent infection, ensuring that treatment is tailored to the individual.
The diagnostic process includes:
Detailed clinical history and symptom assessment
Your ENT consultation begins with understanding your symptoms, including duration, severity and triggers. This may include nasal blockage, facial pressure, discharge and breathing difficulties. Your ENT specialist will also assess how symptoms affect daily activities, sleep and quality of life.
ENT examination (nasal assessment)
A physical examination of the nasal passages is performed to check for swelling, discharge, structural abnormalities or visible blockages. This provides an initial assessment of the nasal airway and sinus health.
Nasal endoscopy
A thin, flexible camera is gently inserted into the nose to provide a clear and detailed view of the nasal passages and sinus openings. This allows the specialist to identify inflammation, mucus build-up, nasal polyps or structural obstruction that may not be visible during a standard examination.
CT scan of the sinuses (CT scan sinus)
A CT scan of the sinuses provides detailed imaging of the sinus cavities, helping assess the extent of inflammation, blockage and anatomical variations. This is particularly important when planning treatment or considering nose surgery for sinus conditions, such as functional endoscopic sinus surgery (FESS).
Allergy assessment (if relevant)
If allergies are suspected, testing may be recommended to identify triggers contributing to ongoing inflammation. Managing these triggers can be an important part of long-term treatment.
Additional tests (in selected cases)
In some cases, further evaluation may be required to assess infection patterns or rule out other conditions affecting the sinuses.
These investigations provide a comprehensive understanding of the condition and help determine whether medical management (such as medications and nasal therapy) or surgical treatment is more appropriate. Early and accurate diagnosis plays a key role in preventing complications and improving long-term symptom control.
Early evaluation is important if symptoms persist or worsen over time.
You should consult a specialist if you experience:
Consulting an ENT specialist for sinus treatment allows for early diagnosis and appropriate care.
Sinus surgery refers to procedures that aim to improve sinus drainage, remove blockages and restore normal airflow within the nasal passages.
It is commonly used to treat:
Modern techniques, such as minimally invasive sinus surgery, use small instruments and cameras to reduce tissue disruption and improve recovery outcomes.
Not all sinus conditions require surgery, but it may be recommended when symptoms persist despite treatment.
You may need sinusitis surgery if you experience:
Surgical treatment aims to relieve symptoms and improve overall function.
Benefits include:
Outcomes vary depending on the underlying condition and adherence to follow-up care.
Functional endoscopic sinus surgery (FESS) is the most commonly performed type of ENT sinus surgery, used to treat chronic sinusitis that does not respond to medication.
Balloon sinuplasty is a less invasive procedure that widens blocked sinus passages using a small balloon.
Septoplasty or deviated septum surgery is performed to correct a deviated nasal septum, which can obstruct airflow and contribute to sinus issues.
Turbinate reduction addresses enlarged nasal tissues that can block airflow and contribute to chronic congestion.
Patients considering sinus surgery have access to experienced specialists, advanced medical technology and well-established care pathways designed to support both effective treatment and long-term sinus health.
ENT care is widely available across both public and private healthcare settings, allowing patients to receive timely diagnosis, personalised treatment planning and structured follow-up care.

What to look for in a specialist
Choosing the right specialist helps ensure that nasal blockage surgery is performed safely and effectively, with appropriate guidance throughout recovery and ongoing care for sustained results.
Preparation is important for a safe procedure and smooth recovery.
Patients are advised to:
Proper preparation supports better outcomes and reduces risks.
Modern ENT sinus surgery is performed using minimally invasive techniques, focusing on restoring natural sinus drainage while preserving surrounding structures.
1. Preparation and anaesthesia – The procedure is usually performed under general or local anaesthesia, depending on the case. The nasal passages are carefully prepared in a sterile environment to ensure safety and precision throughout the surgery.
2. Endoscopic access to the sinuses – A thin, flexible camera called an endoscope is inserted into the nasal passages. This allows the surgeon to obtain a clear, magnified view of the sinuses without making external incisions.
3. Removal of blockages – Blocked or diseased tissue is carefully removed, including inflamed sinus lining, mucus build-up or nasal polyps. This step helps eliminate the source of obstruction and ongoing inflammation.
4. Widening of sinus openings – The natural drainage pathways of the sinuses are gently enlarged to improve airflow and mucus drainage. This is a key part of functional endoscopic sinus surgery (FESS) and helps prevent future blockages.
5. Completion and recovery – Once the sinuses are cleared and drainage is restored, the procedure is completed without the need for external stitches. Most patients can return home on the same day.
Sinus surgery takes 30–90 minutes, depending on the complexity of the condition. This minimally invasive approach allows for precise treatment with minimal disruption, supporting a smoother recovery and improved long-term outcomes.
Recovery after sinus surgery is gradual and varies depending on the severity of the condition, the extent of surgery and individual healing response. Understanding each stage can help patients prepare for recovery and manage expectations.
During the first few days after ENT sinus surgery, the focus is on initial healing and symptom management.
During this phase:
Patients are usually advised to avoid nose blowing and follow prescribed medications or nasal care instructions.
Symptoms begin to improve as swelling gradually reduces.
During this phase:
Follow-up appointments may be scheduled to assess healing and clear any residual debris.
Breathing and sinus function typically improve more noticeably.
During this phase:
Patients often begin to notice a meaningful improvement in symptoms compared to before surgery.
Most patients reach a stable stage of recovery.
During this phase:
Healing continues internally, and ongoing care helps maintain results.
Long-term outcomes after sinus surgery vary depending on the underlying condition, severity of inflammation and adherence to ongoing care. For many patients, the procedure provides meaningful and sustained relief.
Overall, while results vary between individuals, ENT sinus surgery can provide significant improvement in symptoms when combined with appropriate post-operative care and long-term management.
As with any nose surgery for sinus, there are potential risks.
Risks of sinus surgery include:
These risks are generally low and are managed with appropriate care.
In some cases, non-surgical options may be effective.
These include:
These approaches focus on sinus infection treatment, but may not be sufficient for chronic cases.
The cost of sinus surgery can vary depending on several factors, including the complexity of the condition, the type of procedure performed and the healthcare setting. Understanding these components helps patients plan more effectively and make informed decisions about treatment.
The total cost of sinus surgery is influenced by:
Patients are encouraged to discuss a detailed cost breakdown during consultation, including surgical fees, hospital charges and follow-up care, to fully understand the financial aspects of treatment.
Sinus surgery may be recommended when symptoms persist despite medication or significantly affect daily life.
The procedure is done under anaesthesia. Some discomfort after surgery is expected but usually manageable.
Initial recovery takes about one to two weeks, but full healing may take several weeks.
Most procedures take between 30 and 90 minutes.
It can significantly improve symptoms, but ongoing care may still be needed.
Yes, it is generally safe when performed by an experienced specialist.
Many patients return to light work within one to two weeks.
No, most procedures are internal and do not affect external appearance.
Nasal polyps removal is a procedure to remove soft growths in the nasal passages that can block airflow and cause sinus symptoms.
Septoplasty corrects a deviated septum to improve airflow, while sinus surgery treats blocked or inflamed sinuses.
Chronic sinus problems can affect your breathing, sleep quality and overall comfort if left untreated. Whether your symptoms started recently or have been ongoing, early assessment is important to identify the cause and guide the most appropriate treatment.
