What is Chronic Sinusitis?
Chronic sinusitis, also known as chronic rhinosinusitis, is a prolonged inflammation of the sinus and nasal passages. This condition typically lasts more than 12 weeks, resulting from persistent inflammation that causes the sinus cavities to swell and obstruct the normal drainage of mucus. Sinusitis can be classified into three types based on duration:
- Acute Sinusitis: Lasts less than 6 weeks and is characterized by sudden onset symptoms like nasal congestion, facial pain, and a runny nose.
- Subacute Sinusitis: Lasts between 6 and 12 weeks, with symptoms that are less severe than chronic sinusitis.
- Chronic Sinusitis: Lasts more than 12 weeks and involves prolonged inflammation, recurrent sinusitis, and recurring infections.
Common Symptoms of Chronic Sinusitis
Patients with chronic sinusitis often experience a range of symptoms that can significantly impact their quality of life:
- Nasal Congestion: Persistent stuffy nose and difficulty breathing.
- Facial Pain and Pressure: Especially around the eyes, forehead, and cheeks.
- Reduced Sense of Smell: A common sign of nasal blockage and inflammation.
- Postnasal Drip: Mucus drainage down the back of the throat.
- Runny Nose: Continuous nasal discharge, often thick and discolored.
- Ear Pain: Resulting from pressure changes or inflammation spreading to the ears.
- Headaches: Frequent headaches due to sinus pressure.
- Dental Pain: Pain in the upper teeth due to maxillary sinus pressure.
What Causes Chronic Sinusitis?
Chronic sinusitis is typically caused by conditions that narrow or block the drainage channels between the sinuses and the nasal cavity, leading to mucus buildup and bacterial infections.
Primary causes and risk factors include:
- Allergies: Especially to pollen, animal dander, and dust mites, which can trigger inflammation in the nasal passages, leading to swelling and obstruction of the sinus drainage pathways.
- Asthma: Patients with asthma are more prone to developing chronic sinusitis due to the persistent inflammation associated with asthma.
- Nasal Polyps: Noncancerous growths in the nasal passages that can block sinus drainage, contributing to chronic inflammation.
- Structural Abnormalities: Such as a deviated nasal septum or narrow sinus outflow tracts, which can impede mucus drainage, creating an environment conducive to bacterial growth and infection.
In addition to allergies, other factors that can contribute to chronic sinusitis include:
- Fungal Infections: Less common but can occur in patients with weakened immune systems or chronic respiratory conditions, leading to fungal sinusitis.
- Bacterial Infections: Often secondary to viral infections, these can cause inflammation and lead to chronic bacterial sinusitis.
- Viral Infections: Frequently the initial trigger for sinus inflammation, which can then become chronic if not properly managed.
- Underlying Health Conditions: Autoimmune diseases and other chronic respiratory conditions that cause chronic inflammation in the nasal and sinus passages.
How are Chronic Sinus Infections Treated?
The treatment of chronic sinusitis aims to reduce inflammation, eliminate the infection, and restore normal sinus drainage. Medical treatment is usually the first line of defense and involves a combination of medications to address both the bacterial infection and the inflammation.
Medical Treatment Approaches for Sinus Infections
- Antibiotics: Commonly prescribed to reduce the bacterial load within the sinuses and clear bacterial infections. This is crucial in cases of bacterial sinusitis.
- Nasal Corticosteroids: Available as nasal sprays, these help reduce swelling in the nasal passages, improving mucus drainage and alleviating symptoms like nasal congestion and postnasal drip.
- Oral Corticosteroids: Used for more severe symptoms or when nasal polyps are present to manage chronic inflammation.
- Antihistamines: Effective in managing allergy-related symptoms by blocking the body’s allergic reaction, reducing nasal inflammation, and preventing further complications.
- Nasal Irrigation with Saline Solutions: Helps clear mucus and allergens from the nasal passages, reducing inflammation and promoting mucociliary clearance.
- Management of Allergies: Including allergy testing to identify specific triggers and allergy shots (immunotherapy) to build resistance to those allergens.
Effective management of chronic sinusitis involves addressing underlying conditions and lifestyle factors. This includes dealing with nasal blockage caused by structural abnormalities, such as a deviated septum, which is crucial for effective sinusitis management. Allergy management is also essential, involving allergy testing and shots to reduce inflammation by minimizing exposure to allergens. Additionally, treatment plans should consider the possibility of fungal sinusitis or bacterial infections, which may require specific medications to effectively address these underlying causes.
What is Sinus Surgery?
When medical treatment fails to provide relief, sinus surgery may be necessary to address chronic sinusitis. The main goal of sinus surgery is to improve sinus drainage by widening the natural channels within the sinuses and removing any obstructions, such as polyps or scar tissue.
There are several types of sinus surgery that can be performed depending on the severity and location of the sinusitis:
- Functional Endoscopic Sinus Surgery (FESS): FESS is a minimally invasive procedure performed using a high-powered camera on the end of a lighted tube called an endoscope. During FESS, the surgeon can magnify the sinus cavities onto a video monitor, allowing precise removal of infected or inflamed tissue. This surgery is typically performed under general anesthesia, ensuring that the patient remains comfortable and relaxed. FESS is highly effective in opening blocked sinus passages, improving drainage, and reducing the frequency and severity of sinus infections.
- Balloon Sinuplasty: Balloon Sinuplasty is another minimally invasive procedure used to treat chronic sinusitis. During this procedure, a small balloon is inserted into the sinus openings and then inflated with water. The inflation of the balloon widens the sinus passages, allowing for better drainage of mucus and reducing sinus pressure. Balloon Sinuplasty is particularly effective for patients with less severe forms of sinusitis and is often performed under local anesthesia. However, this procedure is not suitable for patients with nasal polyps or more complex sinus conditions like ethmoid sinusitis.
- Image-Guided Surgery: In some cases, especially in revision surgeries or when the sinuses adjacent to the brain and eyes are involved, image-guided surgery may be used. This technique utilizes a 3D visualization system based on the patient’s CT scans to guide the surgeon during the procedure. Image guidance provides enhanced accuracy, particularly in delicate areas like the frontal sinuses, ethmoid sinuses, and sphenoid sinuses, where the risk of complications is higher.

Chronic sinusitis is a complex condition requiring careful diagnosis and a comprehensive treatment approach. While medical treatment is effective for many patients, surgery may be necessary when symptoms persist despite conservative measures. Functional Endoscopic Sinus Surgery and Balloon Sinuplasty offer minimally invasive options to improve sinus drainage and reduce chronic inflammation, significantly enhancing the quality of life for those suffering from chronic rhinosinusitis.
Working closely with a healthcare provider to develop a personalized treatment plan is essential for managing chronic sinusitis and preventing recurrent infections. With proper management, patients can achieve significant relief from symptoms and prevent future complications.
