Specimens obtained from the sinus cavity can be diagnostic in AFS by showing abundant eosinophils, Charcot-Leyden crystals, and hyphae of fungi. Rhinoscopy is also useful for culture for fungi and to determine if a nasal polyp is present.

For patients with chronic allergic rhinitis that is recurrent or resistant to conventional therapy, the procedure is helpful for identifying adenoid hypertrophy, chronic adenoiditis, nasal polyps, or ethmoidal bullae. If rhinitis is complicated with sinusitis, it helps to determine the obstruction of ostium of sinus tract and/or to collect discharge for microbiologic study.
