Sinus
What are sinus issues?
Sinus issues occur when the sinuses become inflamed, swollen, or blocked. This inflammation, known as sinusitis, may be caused by allergies, infections, irritants, nasal polyps, or other underlying medical conditions.
What are the sinuses?
The paranasal sinuses are four pairs of symmetrical, air-filled cavities located within the bony structures of your skull. They are lined with a thin layer of mucus membrane to help humidify the air you breathe.
The four primary sinus groups are:
• Maxillary Sinuses (Cheeks): Located inside the face behind the cheekbones. They are present at birth and expand as you age.
• Ethmoid Sinuses (Bridge of Nose): Located between the eyes along the bridge of the nose.
• Frontal Sinuses (Forehead): Located above the eyes in the low forehead region; these typically do not develop until roughly seven years of age.
• Sphenoid Sinuses (Deep Facial Structure): Located deep within the skull behind the nasal passage, fully developing during adolescence.
What are the types of sinusitis?
Sinusitis is an inflammation or swelling of the tissue lining your sinus cavities, often triggered by viral infections, local environmental allergies, or underlying structural issues. It is clinically categorized by duration and frequency:
-
Acute Sinusitis (Less than 4 Weeks):
A short-term inflammation that typically develops after a common cold or a seasonal allergy flare-up, resolving quickly with appropriate medical management.
-
Chronic Sinusitis (8 Weeks or Longer)
A persistent inflammation that lasts two months or more. This is frequently driven by underlying environmental allergies, nasal polyps, or repeated, inadequately treated acute infections.
-
Recurrent Sinusitis (3+ Episodes Per Year)
Defined as three or more distinct episodes of acute sinusitis occurring within a single calendar year, necessitating an evaluation by a board-certified allergist to isolate the root cause.
What are the common sinusitis symptoms and how is it diagnosed?
Sinusitis symptoms can vary depending on the severity and cause of the inflammation, but commonly include:
• Facial pressure, pain, or tenderness
• Headaches
• Nasal congestion or stuffiness
• Thick or discolored nasal drainage
• Postnasal drip
• Ear pressure or tooth pain
• Coughing or sore throat
• Reduced sense of smell
• Fever in some cases
Sinus symptoms are often associated with allergies, respiratory infections, or chronic inflammation.
Diagnosing sinus problems usually begins with a review of your symptoms, medical history, and a physical examination. Your doctor may gently examine the sinus areas for tenderness and look inside the nose for signs of inflammation, swelling, nasal polyps, drainage, or other abnormalities.
In some cases, additional testing may be recommended to help determine the cause of chronic or recurring sinus symptoms.
Physical Examination
A thorough physical exam can help identify or rule out other medical conditions that may be contributing to congestion, facial pressure, headaches, coughing, or breathing problems.
Imaging Tests
Imaging studies such as a CT scan or MRI may be used to evaluate the sinuses for inflammation, blockage, structural abnormalities, nasal polyps, or chronic sinus disease.
The connection between allergies and chronic sinusitis
In the Chattanooga, East Tennessee, and North Georgia valley region, high concentrations of seasonal pollens and indoor mold spores frequently cause the nasal passages to swell. When allergies cause your nasal linings to become inflamed, the normal drainage pathways of your sinuses become blocked. This trapped fluid creates an ideal breeding ground for bacteria, leading to painful, recurring sinus infections.
How are sinus issues treated?
At Chattanooga Allergy Clinic, our board-certified allergists focus on treating both immediate sinus discomfort and the underlying allergic triggers to prevent future recurrence. Standard medical therapies include:
• Targeted Allergy Management: Utilizing personalized allergy shots (immunotherapy) or prescription antihistamines to eliminate the underlying immune-system swelling that blocks sinus drainage.
• Nasal Corticosteroid Sprays: Highly effective local anti-inflammatory medications used to shrink swollen nasal passages and reduce tissue swelling.
• Saline Nasal Irrigation: Using a distilled saline rinse or spray to physically clear thick mucus, environmental crusting, and trapped allergens from the nasal cavity.
• Antibiotic Therapy: Prescribed by your physician strictly when a secondary bacterial infection is suspected or confirmed.
