screening for sinus

Overview

Sinus screening is a check-up to look for problems in the sinuses — the small, air-filled spaces inside the bones of your face and head. It helps find signs of infection, inflammation, or other issues that may cause symptoms like a blocked nose, facial pain, or headaches.

Sinus problems are very common. Many people get sinus infections, but screening is usually reserved for those whose symptoms persist, keep coming back, or affect their quality of life.

Anyone can have sinus issues. They are more likely in people with allergies, asthma, a weakened immune system, or structural differences in the nose.

Symptoms

Common symptoms

• Stuffy or blocked nose
• Facial pain or pressure, especially around the cheeks or eyes
• Thick yellow or green nasal discharge
• Reduced sense of smell
• Headache or a feeling of fullness in the head
• Post-nasal drip (mucus running down the back of your throat)

Symptoms in children

• A runny or blocked nose that lasts beyond a typical cold
• Irritability or fussiness
• Ear pain or hearing trouble
• Cough that gets worse at night
• Low-grade fever

Symptoms in older adults

• Symptoms may be less obvious and include fatigue or confusion
• Nasal congestion or discharge that lingers
• Post-nasal drip causing a sore throat or hoarse voice
• Less sensitivity to pain, so facial discomfort may not be noticed

Causes

Main causes

• Viral infections, like the common cold
• Allergies that cause nasal swelling and block mucus drainage
• Bacterial infections that develop when mucus is trapped
• Structural problems, such as a deviated nasal septum or nasal polyps
• Irritants like smoke, air pollution, or strong fumes

Risk factors

• Smoking or exposure to secondhand smoke
• Having asthma or allergic rhinitis
• A weakened immune system from illness or certain medicines
• Conditions that affect mucus clearance, like cystic fibrosis
• Swimming in chlorinated or contaminated water
• Frequent flying or changes in air pressure

When to see a doctor

See a doctor urgently if:

• If you have swelling around the eyes, vision problems, a severe headache, or a stiff neck, get emergency care right away.
• If you have a high fever with a severe headache, seek urgent medical help.

Book a routine appointment if:

• If you have cold-like symptoms that last more than 10 to 14 days without improving.
• If you have had several sinus infections in a year.
• If your symptoms are affecting your work, sleep, or daily life.

Diagnosis

To screen for sinus problems, a doctor will ask about your symptoms and medical history, then examine your nose and face. They may use a small lighted telescope called a nasal endoscope to look inside your nasal passages. If needed, imaging such as a CT scan can give a detailed picture of your sinuses.

Tests that may be done

• Physical exam of your nose, throat, and face
• Nasal endoscopy — a thin, flexible tube with a camera is inserted into the nose
• CT scan of the sinuses — a special X-ray that shows bone and soft tissues clearly
• Allergy testing — if allergies are suspected as a cause
• Tissue sample (biopsy) — only rarely needed if a doctor sees something unusual

What to expect at your appointment

Screening is usually quick and done in the doctor's office. You will sit upright while the doctor gently examines your nostrils. Endoscopy might feel a little uncomfortable, but it is not painful and only takes a few minutes. If you need a CT scan, you'll lie on a table for several minutes and won't feel anything.

Treatment

Treatment for sinus problems depends on the cause and how severe your symptoms are. Many people improve with simple self-care and over-the-counter remedies, while others may need prescription treatments or, in some cases, surgery.

Self-care at home

• Use a saline nasal rinse or spray to keep your nasal passages moist and clear.
• Breathe in steam from a bowl of hot water or a warm shower to soften mucus.
• Apply a warm, damp cloth to your cheeks and forehead to ease facial pain.
• Drink plenty of water to thin mucus.
• Rest and avoid vigorous activity while your symptoms are acute.

Medical treatments

Doctors may recommend treatments such as nasal corticosteroid sprays to reduce swelling, decongestants to unblock the nose for short periods, or pain relievers for discomfort. If a bacterial infection is strongly suspected, antibiotics may be prescribed. Always follow your healthcare provider's advice and never use over-the-counter decongestants for more than a few days without checking with a professional.

When is surgery considered?

Surgery may be considered if medical treatment does not control symptoms, or if there are structural blocks like polyps or a deviated nasal septum. Functional endoscopic sinus surgery is a common procedure that opens up the sinus passages. A specialist will discuss whether you are a candidate.

Living with this condition

Incorporate gentle habits like keeping your nose moist with saline sprays, using a bedroom humidifier, and elevating your head while sleeping to encourage drainage. Track your symptoms to see what makes them better or worse.

Lifestyle tips

• Avoid smoke and strong fumes, which can irritate nasal passages.
• Manage allergies with advice from your doctor on how to reduce allergens at home.
• Wash your hands often to lower your risk of viral infections.
• Use a neti pot or nasal rinse bottle correctly, using distilled or boiled (cooled) water.

Diet and exercise

Drinking plenty of water helps keep mucus thin. Regular physical activity, such as walking or gentle yoga, may help reduce inflammation and improve overall wellbeing. No special diet is proven to cure sinus problems, but a balanced diet rich in fruits, vegetables, and whole grains supports your immune system.

Mental health and emotional wellbeing

Living with ongoing sinus symptoms can be tiring and frustrating. It can affect your sleep, concentration, and mood. Feeling low or anxious is common, especially when symptoms drag on. Be kind to yourself and talk to your doctor if sinus issues are taking a toll on your mental health.

Prevention

Not every sinus problem can be prevented, but you can lower your chances by avoiding triggers, keeping allergies under control, and practicing good hygiene to reduce infections.

Vaccines

Staying up to date with recommended vaccinations, such as the flu vaccine, may help prevent some viral infections that can lead to sinus inflammation. Ask your healthcare provider what vaccines are right for you.

Screening programmes

Screening is not needed for everyone. It is usually considered when you have repeated or lingering sinus symptoms, or if an ENT specialist thinks you may have an underlying problem that needs closer evaluation.

Complications

If left untreated

• An infection can spread to nearby areas, such as the eyes or brain, though this is rare.
• Chronic inflammation can lead to nasal polyps, further blocking the sinuses.
• Long-term symptoms can significantly impact sleep, productivity, and quality of life.

Long-term outlook

The outlook for most sinus problems is good. With the right treatment, many people see major improvement. Even if you need long-term management or surgery, most people can find a plan that helps them feel better and live comfortably.
