Manufacturers of vented ear plugs (e.g., Doc's Proplugs) assert that these devices ease equalization and keep water out of the ears. The latter feature is said to reduce the frequency of otitis externa — more com- monly referred to as swimmer’s ear, which is an infection of the external ear canal — and exostosis, or surfer’s ear, which is an abnormal bone growth within the ear canal. The claim of easing equalization is difficult to support as there is no reasonable mechanism of which I am aware to explain howow this might occur. Doc's Proplugs' web site states, "Due to surface tension, the vented plug also reduces abrupt pressure changes from reaching the sensitive eardrum which contributes to easier equalization,” a line of reasoning that I am unable to follow. To the extent that a vented ear plug lessened the flow of water into the external auditory canal, the expecta- tion is that outer ear infections would be less likely. Decreased water flow also would be expected to re- duce temperature-related abnormalities, such as caloric vertigo and surfer's ear. Although anecdotes abound, only the most minimal acceptable medical research has been conducted on these plugs to date, and all that has been demonstrated is reduced bony growth in the external ear canal caused by exposure to cold, wet and windy conditions during various watersports. Provided that the vent in the plug remains unobstructed, these devices appear to pose little danger to the ear. However, if a vent should become clogged, especially upon descent, equalization could become im- peded and the eardrum damaged. As for using such plugs to protect a ruptured eardrum, remember that these devices still do admit a small amount of water. Plus, the diver runs the risk of losing the plug altogether, thus allowing water to freely enter the middle ear space and cause pain, disorienting vertigo, and possible middle-ear infection. The bottom line is if you're experiencing external ear infections or worried about surfer's ear, properly used vented plugs may be worth the small investment. However, divers with a history of middle-ear congestion or infection are unlikely to benefit from these plugs, and they should refrain from diving until seen by an ear, nose and throat specialist. For those with continuing difficulty in equalizing, experiment with various clearing techniques before trying vented ear plugs. Having trouble equalizing your ears?
