Tympanostomy tube protection with ear plugs

Protection by ear plugs from waterborne infection was evaluated in 35 patients with 'tympanostomy' tubes, tympanic membrane perforations, or mastoid bowls. Stock and custom-made ear plugs were found to be equally effective up to four months during a period of frequent swimming and bathing activities. Infections were only noted to occur in those patients who did not follow instructions on appropriate use of the plugs.
