Allergic Fungal Sinusitis

Allergic fungal sinusitis (AFS) is a very specific type of sinus infection that is caused by environmental allergens. Patients with this condition often have significant associated allergies to mold and other allergens and they may also suffer from nasal polyps or asthma. The infecting fungi may be microscopically present in the air and when they enter the sinus cavity they cause inflammation and infection that creates severe sinus symptoms.


Allergic fungal sinusitis is relatively rare and is a particularly challenging type of sinus infection to treat and manage.1 Houston sinus expert Dr. Arjuna Kuperan is a board-certified ENT and fellowship-trained Rhinologist with the skill and experience to help patients with allergic fungal sinusitis. Dr. Kuperan uses his expertise to determine the underlying cause of sinus symptoms and create a customized treatment plan to relieve sinus symptoms.


  • Difficulty breathing or nasal congestion on one side of the nose
  • Facial pain or pressure on only one side of the face
  • Thick yellow/brown nasal drainage
  • Intermittent nasal discharge of green/brown “cork-like” fragments
  • More frequent asthma exacerbations with wheezing or chest tightness
  • Coughing

If you suffer from recurring sinus infections or symptoms of allergic fungal sinusitis, it is critical to see an experienced Rhinologist. Proper treatment is important because allergic fungal sinusitis can cause complications, including vision loss, if left untreated.2 Dr. Kuperan will use a variety of diagnostic tools to determine if a fungal infection is the cause of your sinus issues. He will discuss your diagnosis and your treatment options with you. Oral steroids and antibiotics can provide temporary relief of symptoms, but a long-term care plan is necessary to prevent allergic fungal sinusitis from coming back.

Most patients with allergic fungal sinusitis require endoscopic sinus surgery in conjunction with allergy testing and treatment. The quality of the endoscopic sinus surgery is critical to ensure long term control of this particularly challenging sinus infection. Wide sinus openings must be created to remove all the fungal fragments and provide accessibility for long-term therapy with nasal steroid rinses to keep the inflammation controlled. Dr. Kuperan offers the revolutionary technology of Propel steroid releasing implants that produce steroid locally inside the nose to prevent recurrence of fungal growth and polyps.
