Stenosis of the external ear canal: prevention using hydroxylated polyvinyl acetal wicks.

Hydroxylated polyvinyl acetal wicks may be very helpful in preventing postsurgical stenosis of the external ear canal. The wick is inserted into the canal, wetted with Polysporin Otic, and changed periodically until scar tissue becomes stabilized. This method is simple, quick, and well tolerated by the patient. Polyvinyl wicks provide a useful adjunct in preventing stenosis of the external ear canal.
