[edit] Description

The Olfactory nerve or cranial nerve I evaluation is usually skipped on a cranial nerve exam. Smell is tested in each nostril separately by placing stimuli under one nostril and occluding the opposing nostril. The stimuli used should be non-irritating and identifiable. Some example stimuli include cinnamon, clovs and toothpaste. Bilateral loss can occur with rhinitis, smoking or aging. Unilater loss indicates a possible nerve lesion or deviated septum.
