Chronic Sinusitis: A Clear Guide to Symptoms, Diagnosis and Treatment

Chronic Sinusitis: A Clear Guide to Symptoms, Diagnosis and Treatment

Chronic sinusitis (also called chronic rhinosinusitis) is ongoing inflammation of the nose and sinus linings, commonly defined as lasting 12 weeks or longer. Adults with this condition often experience persistent nasal blockage, facial pressure, thick discharge and a reduced sense of smell. This guide explains what causes chronic sinusitis, how an ENT specialist diagnoses it, safe treatment options and when to seek urgent care. If you live in Thane or nearby areas, this overview will help you prepare for a focused discussion with your doctor.

What is chronic sinusitis?

Sinuses are air-filled spaces around the nose that normally produce mucus, which drains through small channels. In chronic sinusitis, the lining stays swollen and inflamed for a long period. This can narrow the drainage pathways, trap mucus and make the area more prone to infection and ongoing symptoms.

How it differs from acute sinusitis:

• Acute sinusitis: Usually starts after a cold and settles within a few weeks.
• Chronic sinusitis: Symptoms persist for many weeks and may fluctuate, with better and worse periods.

Common symptoms adults notice

People with chronic sinusitis may have several of the following:

• Nasal blockage or stuffiness
• Thick nasal discharge (often yellowish/greenish) or postnasal drip
• Facial pressure or pain around the cheeks, forehead, between the eyes or upper teeth
• Reduced or altered sense of smell and taste
• Cough (often worse at night due to mucus dripping from the back of the nose)
• Ear pressure or fullness, bad breath, fatigue, disturbed sleep

Symptoms can overlap with migraines, dental problems and allergies, so a proper ENT evaluation is helpful for a clear diagnosis.

When to seek urgent medical attention

Though most chronic sinusitis is not dangerous, seek urgent care if you develop:

• Swelling or redness around the eyes, vision changes or severe eye pain
• Severe, sudden or worsening headache, stiff neck, confusion or high fever
• Severe facial swelling, intense facial pain or persistent vomiting

These symptoms are uncommon but may signal a complication that needs prompt assessment.

Why does chronic sinusitis happen? Common causes and risk factors

Chronic sinusitis has multiple contributing factors, which can vary from person to person:

• Allergic rhinitis: Ongoing nasal allergies can inflame the sinus lining.
• Nasal polyps: Soft, non-cancerous growths inside the nose/sinuses that block airflow and drainage.
• Structural issues: A deviated septum or narrow drainage pathways can hinder mucus flow.
• Repeated infections: Frequent colds or acute infections may lead to chronic inflammation.
• Asthma and aspirin sensitivity: These can be associated with more severe or polyp-related sinusitis.
• Environmental irritants: Smoke, dust, strong fumes and air pollution can worsen inflammation. During high pollution days in cities like Thane/Mumbai, symptoms may flare.
• Dental infections: Upper tooth infections sometimes spread to the maxillary sinus.
• Immune problems: Less commonly, reduced immunity or specific inflammatory conditions can play a role.

How an ENT diagnoses chronic sinusitis

A thorough evaluation helps confirm the diagnosis and identify treatable causes:

• History and examination: Your doctor will ask about duration, pattern of symptoms, allergies, asthma and triggers. They will examine your nose, throat and ears.
• Nasal endoscopy: A thin, flexible endoscope is used in the clinic to look inside the nose for swelling, mucus, pus, polyps or structural issues. This is a brief procedure that most adults tolerate well.
• CT scan of the sinuses: Not always required. It may be recommended when symptoms are persistent despite treatment, before surgery, or if complications are suspected.
• Allergy testing: Considered if allergies seem to drive symptoms.
• Swabs or cultures: Occasionally taken if infection persists or unusual organisms are suspected.

An ENT specialist will also consider other causes of facial pain or headaches, such as migraine, nerve pain or dental issues.

Treatment options: stepwise and individualised

Management is tailored to your symptoms, findings on examination and any related conditions like allergies or asthma. Many people improve with consistent medical therapy and lifestyle changes. Surgery is considered when appropriate, especially for persistent symptoms due to blockages or nasal polyps.

Self-care and home measures

• Saline nasal irrigation: Rinsing with a sterile saline solution can help clear mucus and allergens. For safety, use distilled or sterile water, or water that has been boiled and cooled. Clean and air-dry the device after each use.
• Nasal hygiene: Gentle nose blowing; avoid forcefully sniffing mucus back.
• Steam inhalation: May provide temporary relief from congestion; take care to avoid burns and stop if it worsens breathing.
• Allergen and irritant control: Reduce exposure to dust, smoke and strong fumes. During high-pollution days, consider staying indoors or using a well-fitted mask when outdoors.
• Hydration and sleep: Adequate fluids and good sleep support recovery.
• Quit smoking and avoid second-hand smoke: Smoke inflames the nasal lining and slows healing.

Medical treatment (prescribed by your doctor)

• Intranasal corticosteroid sprays or rinses: Often form the backbone of long-term management to reduce inflammation and polyps.
• Short courses of oral medicines: In selected cases, your doctor may prescribe medicines to calm severe inflammation or treat suspected bacterial infection. These should only be taken under medical supervision.
• Allergy-focused therapy: Antiallergy medicines, nasal antihistamine sprays or allergen immunotherapy may help when allergies are a major trigger.
• Decongestants: Short-term use may be advised in specific situations. Overuse of certain nasal decongestant sprays can worsen blockage (rebound congestion), so avoid using them without guidance.
• Biologic therapies: In select patients with significant nasal polyps not responding to standard therapy, specialist-prescribed biologic medicines may be considered.

Because medication choice and duration depend on your examination and history, please do not start, stop or change prescription medicines without medical advice.

When is surgery considered?

Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure used when symptoms continue despite appropriate medical therapy, or when there are nasal polyps, structural blockages or certain complications. Using small endoscopes, the surgeon opens natural drainage pathways and removes diseased tissue or polyps, helping sinuses ventilate and allowing medicines to reach the lining more effectively.

Surgery is not a guaranteed cure for every patient, but many people experience meaningful symptom relief and fewer flare-ups when surgery is chosen for the right reasons and followed by ongoing medical care. Your ENT will discuss expected benefits, risks and aftercare based on your specific condition.

In Thane, endoscopic ENT surgery is commonly available. If you are considering this option, an in-person consultation will help determine whether it is appropriate for you.

Living well with chronic sinusitis: practical tips

• Follow your doctor’s plan consistently, even when symptoms improve.
• Make saline rinses part of your routine if advised, and use safe water as noted.
• Manage allergies: keep bedding dust-free, use protective covers, and ventilate rooms when air quality is acceptable.
• Avoid smoke and minimise exposure to strong fragrances or cleaning chemicals.
• During viral seasons, wash hands regularly and avoid close contact when unwell.
• Address dental problems early, especially upper tooth pain.
• Keep vaccinations up to date as advised by your physician.

Frequently asked questions

Is chronic sinusitis contagious?

No. The chronic inflammation itself is not contagious. However, colds that can trigger flare-ups are caused by viruses that can spread from person to person.

How is chronic sinusitis different from a common cold or an acute sinus infection?

A cold usually improves within days. Acute sinusitis can follow a cold and settles within a few weeks. Chronic sinusitis lasts much longer, with persistent nasal blockage, discharge, facial pressure and smell disturbance. An ENT evaluation helps distinguish it from other causes like migraine or dental pain.

Do I need a CT scan to diagnose chronic sinusitis?

Not always. Many cases can be assessed with history, examination and nasal endoscopy. A CT scan is recommended selectively—such as when symptoms persist despite treatment, before surgery, or if complications are suspected.

Can allergies or nasal polyps cause chronic sinusitis?

Yes. Allergic rhinitis can inflame the nasal lining and worsen sinus blockage. Nasal polyps are benign growths that obstruct airflow and drainage. Treating allergies and, when needed, shrinking or removing polyps can significantly improve symptoms.

Will surgery cure my chronic sinusitis?

Surgery can open blocked pathways and improve the delivery of medicines to the sinus lining. Many patients feel better after appropriately selected surgery, but it is not a guarantee. Most people still need ongoing medical care to keep inflammation controlled.

Are saline nasal rinses safe to use daily?

They are generally safe when used correctly. Always use sterile, distilled or previously boiled and cooled water; keep the device clean and let it air-dry. If rinses cause ear pain, nosebleeds or worsening symptoms, stop and discuss with your doctor.
