Abstract

Objective

The application of moisture to the ear is anecdotally claimed to relieve the pain from otic barotrauma that can arise during aircraft descent. We tested this claim in a randomized double-blind study on an aircraft with eight participants heavily predisposed to barotrauma.

Methods

On the outward flight half the participants wore “active” devices that applied moisture to the external ear; the remainder wore placebo devices that contained no moisture, but were otherwise identical. On the return flight the groups were reversed. Participants wore the devices from just before descent until landing unless they experienced symptoms of barotrauma, in which case they switched to what they knew was an active device.

Results

There was no significant difference between conditions for the appearance of the tympanic membrane on landing or for the discomfort levels immediately before and after any switch.

Conclusions

Applying moisture is ineffective for passengers heavily predisposed to otic barotrauma.
