BACKGROUND: Symtomatology of nasal polyps (NP) is relatively non-specific and other nasal conditions that cause nasal may be mistaken for NP. The purpose of this study was to evaluate the accuracy otoscopic (OT) examination in detecting presence of NP by using fiberoptic rhinoscopy (FR) as the gold standard to confirm diagnosis of NP. METHODS: Charts from a single allergy clinic were reviewed for any patient having NP diagnosed by FR. Data collected included gender, age, allergy skin test results, and presence of asthma, aspirin allergy, previous nasal surgeries, intranasal corticosteroid use and leukotriene receptor antagonist use. RESULTS: The OT examination had 44% sensitivity. In this study, more than half (56%) of patients with NP would have had their NP missed if FR had not been performed in addition to the OT examination. CONCLUSIONS: The standard physical examination procedure is often not sufficient to confirm a diagnosis of NP. FR should be considered in the investigation of patients with rhinitis symptoms.
