Chronic sinusitis, also known as chronic rhinosinusitis, is a condition in which the sinuses become inflamed and remain swollen for an extended period of time. This persistent inflammation can block normal sinus drainage and cause ongoing symptoms such as congestion, facial pressure, and nasal discharge.
At Certified Allergy & Asthma Consultants, we evaluate and treat patients throughout New York’s Capital Region who experience persistent sinus symptoms that do not resolve with standard treatments. Identifying the underlying cause of chronic sinus inflammation is essential for improving symptoms and preventing recurring infections.
Chronic sinusitis is typically diagnosed when sinus symptoms last 12 weeks or longer, even with treatment.
The sinuses are air-filled cavities located within the bones around the nose and eyes. These spaces normally produce mucus that drains through small openings into the nasal passages.
When the sinuses become inflamed, these drainage pathways may become blocked, allowing mucus to build up and create an environment where infection and irritation can occur.
Chronic sinusitis involves long-term inflammation of the sinus lining, which may be caused by infections, allergies, nasal polyps, or structural issues affecting sinus drainage.
Symptoms of chronic sinusitis often persist for weeks or months and may vary in severity.
Common symptoms include:
Some patients may also experience ear pressure or dental pain due to sinus inflammation.
Several conditions can contribute to chronic sinus inflammation.
Common causes include:
Certain immune system disorders may increase the risk of chronic sinus inflammation or recurrent infections.
Identifying the underlying cause helps guide effective treatment.
Diagnosing chronic sinusitis begins with a review of symptoms and medical history.
At Certified Allergy & Asthma Consultants, evaluation may include:
Additional evaluation may be recommended depending on symptoms and suspected causes.
Treatment focuses on reducing inflammation, improving sinus drainage, and addressing underlying triggers.
Medications may include:
Allergies are a common contributor to chronic sinusitis. Ongoing exposure to allergens such as pollen, dust mites, mold, or pet dander can cause persistent nasal inflammation that interferes with normal sinus drainage.
Treating underlying allergies may significantly improve sinus symptoms and reduce the risk of recurrent sinus infections.
