What is chronic sinusitis?

Definition and general information

Chronic sinusitis, also known as chronic sinusitis, is a long-term inflammatory disease that affects the sinuses and can persist for more than 12 weeks without significant improvement in symptoms despite treatment. This disease causes inflammation of the lining of the sinuses, which can lead to a constant feeling of congestion, facial pain and a runny nose. Chronic sinusitis is common and affects approximately 11% of adults in Europe, making it a major public health issue.

The sinuses are air-filled cavities in the skull that are connected to the nasal cavity. Each sinus has its own drainage path, which can become blocked if the lining becomes inflamed or swollen. Chronic sinusitis can be associated with other respiratory disorders, such as asthma or allergies, making diagnosis and treatment particularly challenging.

Causes and risk factors

The etiology of chronic sinusitis is multifactorial, including both infectious and non-infectious causes. Common infectious agents include bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Less commonly, it may be associated with fungal infections, especially in immunocompromised patients.

Non-infectious risk factors include allergies, such as allergic rhinitis, which can cause swelling of the nasal mucosa. Anatomical variations such as nasal septal deviation, polyps, or cysts can interfere with normal sinus drainage and contribute to chronic inflammation. Other possible predisposing factors include smoking, air pollution, and long-term chemical irritation that can damage the nasal mucosa.

Immune system disorders such as cystic fibrosis or immunodeficiency can also contribute to the development of chronic sinusitis, which reduces the body's ability to fight infections. Stress and lifestyle factors, as well as environmental influences, can affect the course of the disease and the severity of symptoms.

Symptoms of chronic sinusitis

Main symptoms

Symptoms of chronic sinusitis can be diverse and affect the patient's daily life. The main symptoms are a long-lasting feeling of stuffiness in the nose, which can be unilateral or bilateral. Patients often complain of facial pain or a feeling of pressure, which may be localized around the forehead, cheeks or eyes. These symptoms may be constant or worsen at certain times, such as during allergy season.

Other common symptoms include nasal discharge, which can be thick and greenish or yellow in color. Patients may also complain of a reduced sense of smell (anosmia) or even its complete loss. A cough is also often present, especially at night, which occurs due to the drainage of secretions into the throat. Less common but possible symptoms are bad breath (halitosis), fatigue and general malaise. The combination of these symptoms can significantly affect the patient's quality of life.

When to see a doctor

It is important to seek medical attention immediately if symptoms worsen or if they are accompanied by additional symptoms that may indicate complications. These may include a severe headache, swelling around the eyes or face, a fever that indicates a possible bacterial infection, or visual disturbances that may signal orbital or brain involvement. Such symptoms require immediate medical evaluation as they can be life-threatening if not treated properly.

Diagnostic methods

Clinical examination

Clinical examination is the first step in diagnosing chronic sinusitis. The doctor will take a detailed history of the patient, paying attention to the symptoms, their duration and any possible triggers, such as allergies or respiratory disorders. The clinical examination also includes an examination of the nasal cavity with a rhinoscope to assess the condition of the nasal mucosa and detect any anatomical abnormalities or the presence of polyps.

The doctor may also examine the patient's face to determine if there is any soreness or swelling that may be a result of sinusitis. Allergy tests may also be performed during the investigation to determine whether allergies may be involved in causing or worsening the disease. The doctor will also ask about lifestyle factors, such as smoking and work environment, that could affect sinusitis.

Additional diagnostic tests

Additional diagnostic methods help to accurately determine the cause and severity of sinusitis. Imaging tests such as computed tomography (CT) are the gold standard for sinus evaluation because they offer accurate anatomy of the entire sinus and can detect sinus obstruction or polyps. Magnetic resonance imaging (MRI) may be necessary if complications such as orbital or central nervous system involvement are suspected.

Nasal endoscopy is another important method that allows you to directly view the nasal cavity and sinuses, providing the opportunity to take biopsy samples for analysis. A biopsy may be necessary to rule out the presence of fungal infection or tumors. If an allergic component is suspected, specific immunological testing can be performed to identify allergens. These tests will help the doctor develop a personalized treatment plan that meets the patient's individual needs.

Treatment options for chronic sinusitis

Surgical intervention

If conservative treatment has not given the desired result, surgical intervention may be necessary. Functional Endoscopic Sinus Surgery (FESS) is the most commonly used method to help restore normal sinus drainage by removing obstructions and polyps. This minimally invasive technique uses an endoscope to access the sinuses through the nose, reducing the risk of complications and speeding recovery.

Home remedies and lifestyle changes

Lifestyle changes, such as quitting smoking and avoiding polluted air, can make a big difference in controlling the symptoms of chronic sinusitis. Keep the home environment clean and free of allergens such as dust and pet dander. Patients with chronic sinusitis may benefit from the use of humidifiers, especially during the winter months when the air is dry. Stress management and adequate sleep also boost the immune system and help fight infections.

Prevention and long-term management

Preventive measures

Good hygiene practices, such as hand washing, help prevent the spread of viruses and bacteria that can cause sinus infections. Vaccination against influenza and pneumococcal infections may be useful in people with chronic sinusitis to reduce the risk of respiratory infections. Maintain a healthy lifestyle with a balanced diet, regular exercise and adequate sleep to support the immune system and reduce the symptoms of the disease.

Living with chronic sinusitis

Living with chronic sinusitis can be challenging, but with the right management and strategies, it can be successfully controlled. It is important to work with healthcare professionals to develop an individualized treatment plan that meets your specific needs. Regular control visits to the doctor will help to evaluate the effectiveness of the treatment and make the necessary changes.
