Chronic invasive aspergillosis of the paranasal sinuses in immunocompetent hosts from Saudi Arabia.

In immunocompetent patients, paranasal invasive aspergillosis is rare and has a high recurrence rate. Twenty-three cases of paranasal invasive aspergillosis, involving 14 male and nine female immunocompetent patients were reviewed. All patients were cancer-free, HIV-negative, with normal WBC, and none of the patients had received immunosuppressive therapy or corticosteroids. Mean duration of symptoms before diagnosis was 18 months. Aspergillus flavus was the species most frequently isolated. Surgical debridement was performed in all patients followed by antifungal therapy in 18 patients. Mean follow-up duration was 30 months. Fourteen patients relapsed after a mean of 13 months and required an average of 4.3 admissions for repeat surgical evacuation. In a logistic regression model, relapse was not associated with age, duration of symptoms, clinical findings, extent of disease, or mode of therapy. However, patients who were relapse-free tended to have had complete surgical evacuation followed by antifungal therapy.
