Aspergillus infections in the head and neck.

Aspergillus is a chronic colonizer as well as a nidus of infection in the sinuses and ears. In the sinuses, the severity of the disease is classified by the invasiveness of the infection. Invasive fungal sinusitis varies in its presentation based upon the infective organism and shows reduced morbidity if identified early, which requires a high index of suspicion. Allergic fungal sinusitis was recently further classified using a radiologic staging system and was proven to have symptomatic improvement with the concomitant use of surgery and immunotherapy. Finally, fungal ball appears to be a chronic problem that is usually cured with surgery. Aspergillus in the ear is a relatively common problem often related to prolonged antibiotic use and almost always successfully treated with topical antifungals.
