Chronic Sinusitis

Chronic sinusitis, also known as chronic rhinosinusitis, is a common inflammatory condition characterized by persistent inflammation of the sinus and nasal cavities, which lasts for more than 12 weeks. It is estimated that approximately 12.5% of the US population suffers from chronic sinusitis, with more than 29 million people diagnosed with this condition each year. Chronic sinusitis can have a significant impact on a patient's quality of life, leading to impaired physical and emotional well-being, reduced productivity, and increased healthcare utilization. In this article, we will discuss the causes, symptoms, diagnosis, and treatment options for chronic sinusitis.


The exact cause of chronic sinusitis is not fully understood. However, several factors have been implicated in its development. These include:

  1. Allergic rhinitis: Allergic rhinitis is an allergic reaction to substances such as dust, pollen, and animal dander. It causes inflammation of the nasal lining and can lead to the development of chronic sinusitis.

  2. Nasal polyps: Nasal polyps are soft, non-cancerous growths that develop in the lining of the nose or sinuses. They can obstruct the nasal passages and cause chronic sinusitis.

  3. Deviated septum: The nasal septum is the wall that divides the two nostrils. A deviated septum occurs when this wall is not straight, leading to blockage of the nasal passages and development of chronic sinusitis.

  4. Immune system disorders: Immune system disorders such as HIV, cystic fibrosis, and Kartagener's syndrome can cause chronic sinusitis.

  5. Infections: Chronic sinusitis can develop following a viral or bacterial infection of the sinuses.


The symptoms of chronic sinusitis can vary from person to person. The most common symptoms include:

  1. Nasal congestion: Chronic sinusitis can cause a blockage of the nasal passages, leading to difficulty breathing through the nose.

  2. Sinus pressure: Patients with chronic sinusitis may experience pain or pressure around the sinuses, which are located in the forehead, cheeks, and nose.

  3. Post-nasal drip: Chronic sinusitis can cause excessive mucus production, leading to the sensation of mucus dripping down the back of the throat.

  4. Headache: Patients with chronic sinusitis may experience headache, especially in the forehead and around the eyes.

  5. Loss of sense of smell: Chronic sinusitis can cause a loss of sense of smell, which can affect a patient's ability to taste food.

  6. Fatigue: Patients with chronic sinusitis may experience fatigue and a general feeling of malaise.


The diagnosis of chronic sinusitis is based on a combination of symptoms, physical examination, and imaging studies. The following diagnostic tests may be performed:

  1. Endoscopy: Endoscopy involves inserting a thin, flexible tube with a camera on the end into the nasal passages to examine the sinuses.

  2. Imaging studies: Imaging studies such as CT scans or MRI may be used to evaluate the sinuses and identify any abnormalities.

  3. Allergy testing: Allergy testing may be performed to identify any allergens that may be contributing to the development of chronic sinusitis.

  4. Nasal swab: A nasal swab may be taken to check for bacterial or fungal infections.


The treatment of chronic sinusitis depends on the underlying cause and severity of the condition. The following treatment options may be recommended:

  1. Nasal saline irrigation: Nasal saline irrigation involves flushing the nasal passages with a saltwater solution to reduce inflammation and remove excess mucus.

  2. Nasal corticosteroids: Nasal corticosteroids are medications that reduce inflammation in the nasal passages and

treatment of chronic sinusitis

3.  Antibiotics: Antibiotics may be prescribed if there is evidence of a bacterial infection.

4.  Antihistamines: Antihistamines may be used to reduce allergy symptoms and inflammation in the nasal passages.

5.  Surgery: Surgery may be recommended for patients with chronic sinusitis who do not respond to other treatments. Surgery may involve removing polyps or correcting a deviated septum.

6.  Immunotherapy: Immunotherapy may be recommended for patients with chronic sinusitis who have allergies. Immunotherapy involves injecting small amounts of allergens over time to help the body build up a tolerance to the allergens.

7.  Lifestyle changes: Lifestyle changes such as avoiding allergens, quitting smoking, and staying hydrated may help reduce symptoms of chronic sinusitis.


There are several steps that can be taken to help prevent chronic sinusitis:

  1. Practice good hygiene: Wash your hands frequently and avoid touching your face to reduce the risk of infection.

  2. Manage allergies: Take steps to manage allergies such as avoiding allergens and taking allergy medications as prescribed.

  3. Quit smoking: Smoking can irritate the sinuses and increase the risk of infection.

  4. Stay hydrated: Drink plenty of water to help thin mucus and reduce congestion.

  5. Use a humidifier: Use a humidifier to add moisture to the air and reduce dryness in the nasal passages.

Chronic sinusitis is a common condition that can cause significant discomfort and impair a patient's quality of life. The condition can be caused by a variety of factors, including allergies, nasal polyps, and immune system disorders. The symptoms of chronic sinusitis can vary from person to person and may include nasal congestion, sinus pressure, post-nasal drip, headache, loss of sense of smell, and fatigue. Treatment options for chronic sinusitis may include nasal saline irrigation, nasal corticosteroids, antibiotics, antihistamines, surgery, immunotherapy, and lifestyle changes. Taking steps to prevent chronic sinusitis, such as practicing good hygiene, managing allergies, quitting smoking, staying hydrated, and using a humidifier, can help reduce the risk of developing the condition.
