Typical symptoms include a stuffy nose, a feeling of pressure in the face, headaches, and a reduced sense of smell.
Here you’ll find more information about the symptoms of sinusitis, diagnostic and treatment options, and a list of recommended doctors.
What is sinusitis?
Sinusitis is an inflammation of the mucous membranes in the paranasal sinuses—that is, the air-filled cavities in the skull that are connected to the nasal cavity.
These include the frontal sinuses, maxillary sinuses, ethmoid sinuses, and sphenoid sinus. Each sinus is lined with mucous membrane and is connected to the nose via small openings.
Doctors distinguish between two forms of sinusitis:
- Acute sinusitis: It usually develops following a cold and typically lasts less than 12 weeks.
- Chronic sinusitis: If symptoms persist for more than 12 weeks, it is considered a chronic form. It can be persistent or recurrent.
Normally, the mucous membrane produces mucus that traps dust, foreign particles, and pathogens. The secretion can drain toward the nose and throat through the connecting passages. In sinusitis, the mucous membranes are irritated, swollen, or inflamed. This impairs ventilation, and the sinus cavity can no longer drain properly.
For those affected, the condition often significantly impairs quality of life due to a stuffy nose, headaches, and a general feeling of being unwell.

Typical symptoms of sinusitis
Symptoms vary depending on the location of the affected sinus. Common symptoms include:
- A stuffy or runny nose
- A feeling of pressure in the face, especially in the forehead, eyes, and cheeks
- Headaches that may worsen when bending over
- Reduced sense of smell
- Fatigue and exhaustion
- Purulent nasal discharge
- Fever in cases of bacterial infection
- Facial pain or pressure over the maxillary sinuses
Note: When multiple paranasal sinuses are inflamed at the same time, the condition is called pansinusitis.
If, for example, the maxillary sinuses are affected, pain may occur in the cheek area or along the upper jaw. “Sinusitis maxillaris” specifically refers to this location.
Causes and Risk Factors of Sinusitis
Acute inflammation usually results from a viral infection of the upper respiratory tract—that is, a common cold caused by a virus. The swelling prevents mucus from draining properly, creating an ideal breeding ground for bacteria.
Possible pathogens include:
- Viruses (e.g., in the case of colds)
- Bacteria (often due to a secondary infection)
- Less commonly: fungi
Risk factors for developing sinusitis include:
- Allergies (e.g., hay fever)
- Bronchial asthma
- Deviated nasal septum
- Nasal polyps
- Intolerance to analgesics
- Smoking
- Chronic irritation caused by pollutants or dry air
- Anatomically caused narrowings
How is sinusitis diagnosed?
Diagnosis begins with a detailed medical history and an examination of the nose and nasal mucosa. The following examination methods are used:
- Nasal endoscopy: Viewing the nasal cavity with a small camera
- Ultrasound (especially in children)
- Computed tomography (CT): Important in cases of chronic sinusitis or prior to surgery
- Allergy tests: If an allergic component is suspected
- Swab test: If a bacterial infection is suspected
Treatment of symptoms
Treatment depends on whether the sinusitis is acute or chronic and on the underlying cause. The goal is to soothe the mucous membranes, improve drainage, relieve pain, and restore respiratory function.
Acute Sinusitis – Treatment:
In most cases, acute sinusitis resolves without specific treatment. The following may be helpful:
- Nasal sprays or drops containing a decongestant (for no longer than 7 days)
- Inhalations with saline solution
- Drinking plenty of fluids to thin the mucus
- Pain relievers as needed
- Moist heat (e.g., steam baths, nasal rinses)
Antibiotics may be necessary only in cases of a bacterial infection.
Home remedies such as inhalations, staying well-hydrated, sleeping with your head elevated, and nasal rinses can help manage mild rhinosinusitis. They are not a substitute for a medical evaluation if you experience severe pain, a high fever, or persistent symptoms.
Chronic Sinusitis – Treatment:
In the chronic form, structural or inflammatory changes are usually the cause. Treatment options include:
- Cortisone-containing nasal sprays or tablets
- Allergy treatment, if an allergy is involved
- Surgery (e.g., endoscopic sinus surgery) for severe symptoms or anatomical narrowings
The goal of sinus surgery is to improve ventilation and drainage of the sinuses.
Course and Prognosis
Acute sinusitis usually resolves without complications within 1 to 2 weeks. It is important to treat it thoroughly to prevent the infection from spreading to adjacent structures (e.g., eyes, brain).
Chronic sinusitis can significantly impair quality of life. However, with proper treatment of sinusitis (medication or surgery), symptoms can usually be well controlled.
Complications are rare but can be serious. In exceptional cases, the inflammation can spread to the eye socket, the periosteum, or the brain. Therefore, severe, one-sided, or suddenly worsening symptoms should be evaluated by a doctor.
Which specialists are responsible for this condition?
An ENT specialist (ear, nose, and throat doctor) is the appropriate specialist for diagnosis and treatment. For the treatment of chronic rhinosinusitis, head and neck surgeons, among others, are responsible.
Conclusion
Sinusitis is a common and often unpleasant condition. While the acute form is usually harmless, chronic sinusitis can be persistent. With an early diagnosis and the right treatment, complications can be avoided and symptoms significantly alleviated.
Frequently Asked Questions
What provides quick relief from sinusitis?
For acute sinusitis, decongestants, inhalations, nasal rinses, staying well-hydrated, and rest often help. A short-term use of a nasal spray can make breathing easier.
How long does sinusitis last?
Acute sinusitis usually lasts from a few days to about 2 weeks. If symptoms persist for longer than 12 weeks, the condition is considered chronic and should be evaluated by an ENT specialist.
Is sinusitis contagious?
Sinusitis itself is not directly contagious. However, the underlying infection—such as a cold—can be contagious and is transmitted through droplets or contact.
When should you see a doctor?
It’s a good idea to see a doctor if symptoms last longer than 10 days, if you have a high fever, if you experience severe facial pain, or if your symptoms worsen again after a brief improvement.
