Design: A prospective pilot, non-blinded, non-controlled study with case series evaluating a new treatment. Setting: Secondary hospitals. Patients and methods: The present study included 26 elderly patients with non-obstructive dysphagia. Ointment containing 0.025% capsaicin (0.5 g) was applied to the external auditory canal with a cotton swab under otoscope only once or once a day for 7 days before swallowing of a bolus of colored water (3 mL), which was recorded by transnasal videoendoscopy and evaluated according to the endoscopic swallowing score. Results: After a single application of 0.025% capsaicin ointment to the right external auditory canal, the endoscopic swallowing score was significantly decreased, and this effect lasted for 60 minutes. After repeated applications of the ointment to each external auditory canal alternatively once a day for 7 days, the endoscopic swallowing score decreased significantly in patients with more severe non-obstructive dysphagia. Of the eight tube-fed patients of this group, three began direct swallowing exercises using jelly, which subsequently restored their oral food intake.Conclusion: These findings suggest that stimulation of the external auditory canal with ointment containing capsaicin improves swallowing function in elderly patients with non-obstructive dysphagia. By the same mechanism used by angiotensin-converting enzyme inhibitors to induce cough reflex, which has been shown to prevent aspiration pneumonia, aural stimulation with capsaicin may reduce the incidence of aspiration pneumonia in dysphagia patients via Arnold’s ear-cough reflex stimulation.
