Sinusitis is not just a long-term cold or a passing headache, it is a common medical condition that affects the quality of daily life, from breathing and sleep, to concentration and overall mood.

What are sinuses?
The sinuses are four groups of air cavities located inside the facial bones, and are covered by a thin mucous membrane responsible for humidifying and purifying the air before it enters the lungs. These pockets include:
- Frontal sinuses: It is located above the eyes inside the forehead.
- Maxillary sinuses: Located behind the cheeks.
- Ethmoidal sinuses: Between the eyes.
- Sphenoid sinuses: Behind the nose, deep in the skull.
These sinuses work in harmony with the nose to filter air, play a role in reducing head weight, and improving voice tone.
What is sinusitis?
Sinusitis is a condition that occurs when the lining of these cavities becomes swollen or inflamed, leading to blockage of the airways and accumulation of mucus secretions. Inflammation can be:
- sharp: It appears suddenly and lasts less than 4 weeks.
- Chronically: It lasts for more than 12 weeks.
- Repeatedly: It happens several times a year.
There are many causes of inflammation, including viral or bacterial infection, allergies, deviated nasal septum, or the presence of polyps.
The role of the center in treating sinusitis
In our center, sinusitis is not viewed as a passing condition, but rather as a functional disorder that requires comprehensive evaluation and personalized treatment. The center includes an elite group of nose and sinus specialists who use the latest technologies such as:
- High-resolution sinusoscopy.
- Balloon therapy to expand the airways.
- Thermal frequency to shrink nasal polyps.
- Immunotherapy for chronic conditions associated with allergies.
Each treatment plan is designed specifically for the patient's condition, with careful follow-up to ensure continuous improvement.

Types of sinusitis
Sinusitis is classified into several types according to the duration, severity, and frequency of symptoms. Here are the main types:
1- Acute sinusitis
- Duration of injury: Less than 4 weeks.
- the reason: Mostly a viral or bacterial infection after a cold.
- Symptoms: Severe congestion, headache, yellow or green discharge, and facial pain.
- Treatment: It includes rest, decongestants, and in some cases antibiotics.
This type is very common, and often resolves without complications if treated early.
2- Subacute sinusitis
- Duration: From 4 to 12 weeks.
- the reason: Persistent infection or acute infection not adequately treated.
- Symptoms: Similar to acute but less severe, with persistent congestion and discharge.
- Treatment: It requires more careful evaluation, which may include imaging of the sinuses and use of cortisone sprays.
3- Chronic sinusitis
- Duration: More than 12 weeks.
- the reason: Chronic allergies, deviated nasal septum, polyps, or weak immunity.
- Symptoms: Permanent congestion, recurring headaches, loss of sense of smell, and general fatigue.
- Treatment: It often requires specialized intervention, such as immunotherapy or endoscopic surgery.
This type greatly affects the quality of life, and requires periodic follow-up with an ear, nose and throat specialist.
4- Recurrent sinusitis
- Duration: Multiple shifts during the year, each less than 4 weeks.
- the reason: Weak immunity, constant exposure to irritants, or structural problems in the nose.
- Symptoms: The same symptoms of acute inflammation are repeated several times.
- Treatment: It includes prevention, strengthening immunity, and may require adjusting the nasal septum or removing polyps.
Al-Mousa Hospitals: Accurate diagnosis for each type
In our center, a general diagnosis of a sinus condition is not limited to Rather, the type is precisely determined by:
- Endonasal endoscopy.
- CT scan of the sinuses.
- Analysis of secretions when needed.
- Allergy tests.
This precise determination ensures that the most appropriate treatment is chosen, and reduces the possibility of symptoms recurring or the condition developing into a chronic condition.

The difference between viral and bacterial sinusitis
When you have sinusitis, symptoms may seem similar at first: congestion, headache, nasal discharge, and facial pain.
Viral sinusitis
- the reason: It often occurs after a cold or flu
- Duration: It lasts 7 to 10 days
- Symptoms:
- Nasal congestion.
- Clear or yellowish secretions.
- Mild to moderate headache.
- Mild or no fever.
- Gradual improvement without aggressive drug treatment.
- Treatment:
- Comfort
- Drink fluids
- Steam inhalation
- Use saline sprays
- No need for antibiotics
note: More than 90% of acute sinusitis cases are viral, and resolve spontaneously within days.
Bacterial sinusitis
- the reason: The development of a viral infection or prolonged sinus obstruction.
- Duration: Lasts more than 10 days or worsens after initial improvement.
- Symptoms:
- Dense yellow or green nasal discharge.
- Severe pain in the face or teeth.
- Throbbing headache.
- High temperature.
- Bad breath.
- General fatigue.
- Treatment:
- Suitable antibiotics depending on the type of bacteria.
- Cortisone sprays to reduce inflammation.
- Analgesics and antipyretics.
- Medical follow-up to avoid complications.
alert: Using antibiotics without accurate diagnosis may lead to bacterial resistance and health complications.

Sinusitis and allergies: an intertwined relationship
Although sinusitis and allergies are two separate conditions in terms of cause, the relationship between them is close and complex.
How do allergies lead to chronic sinusitis?
Nasal allergies occur as a result of an immune reaction to substances such as dust, pollen, or animal dander. This interaction leads to:
- Swelling of the mucous membranes inside the nose and sinuses.
- Increased mucus secretions.
- Clogged sinus openings.
- Poor drainage and accumulation of secretions.
As this condition continues, the sinuses become an ideal environment for bacteria to grow, leading to chronic or recurring inflammation.

Permanent allergy |
It lasts all year long |
Household dust, animals, and mold |
Chronic congestion, recurring headaches, and partial loss of sense of smell |
Persistent allergies are more closely associated with chronic sinusitis, because they cause persistent blockage in the nasal passages.
