Managing Frontal Sinusitis from Systemic Inflammatory Disease

In this chapter, we outline the systemic diseases that can be encountered in patients with chronic frontal sinusitis, starting with identification of clinical patterns. Next, we compare and contrast the various conditions that may be associated with chronic frontal sinusitis, including allergic fungal sinusitis, aspirin-exacerbated respiratory disease, common variable immune deficiency, eosinophilic granulomatosis with polyangiitis, granulomatosis with polyangiitis, HIV, IgG4-related disease, odontogenic sinusitis, cystic fibrosis, primary ciliary dyskinesia, sarcoidosis, and cocaine-induced midline destructive lesions. We discuss examination features as well as laboratory and radiographic findings. Finally, we review in detail the management options specific to the identified systemic diseases.
