Sinusitis

Sinusitis is a common condition caused by inflammation of the sinus passages, often leading to symptoms such as nasal congestion, facial pressure, headaches, postnasal drip, reduced sense of smell, and fatigue. Many cases of recurrent or chronic sinusitis are driven by underlying allergies, asthma, or immune-related conditions, which is why seeing an allergist can be an important step in long-term relief.

For many patients, recurrent or chronic sinusitis is closely linked to environmental allergies, asthma, or immune system conditions.

How an Allergist Diagnoses Sinusitis

At AllergySA, our allergists specialize in identifying the underlying causes of sinus inflammation, not just treating symptoms. Your evaluation begins with a detailed medical history and physical exam.

If allergies are suspected as a contributing factor to your sinus disease, allergy testing can help identify specific triggers. Long-term treatment options may include allergy immunotherapy, such as allergy shots or drops, to reduce sensitivity and prevent future sinus flare-ups.

Your AllergySA provider may also utilize rhinoscopy, a simple nasal examination that allows your provider to closely view the nasal passages and sinus openings. This will identify inflammation, nasal polyps, drainage, or structural issues that may be contributing to your sinus symptoms.
For patients with ongoing or complicated sinus disease, a CT scan of the sinuses may be recommended.

Personalized Sinusitis Treatment Plans

Once the cause of your sinusitis is identified, your allergist will develop a customized treatment plan. Treatment may include:

• Prescription nasal sprays to reduce inflammation
• Saline rinses to improve sinus drainage
• Antihistamines or other allergy medications
• Short courses of oral medications when appropriate
• Allergy immunotherapy when allergic triggers are a contributing factor

Advanced Treatments for Chronic Sinusitis

For patients with recurrent or chronic sinusitis, especially those with nasal polyps or severe inflammation, your allergist may recommend biologic therapy. These advanced medications target specific immune pathways involved in allergic and inflammatory disease and can significantly improve symptoms and quality of life.
