To the Editor.—
The QUESTIONS AND ANSWERS section includes reference to a water-pick external otitis and perforation of the tympanic membrane.1 I would very much appreciate knowing the basis for this statement. In my hospital, a water-pick instrument and other forms of water irrigation are frequently used. My personal impression is that there has been less damage to the external canal with a water-pick instrument than with the curet. I have seen no data discussing the efficacy and complications of various methods used to remove wax from the external ear. I would very much appreciate having access to the information on which the statements are based.
