The Dansac mini cap: a new method of waterproof ear protection.

The best method of providing waterproof protection for susceptible ears remains a contentious issue. Many evaluations have concentrated on the efficacy of intraluminal plugs in normal or model ears. We describe a new method, using a jejunostomy shower cap (Dansac mini cap), which avoids intraluminal insertion. This method has proved useful in some patients who have failed to avoid repeated otorrhoea after water exposure despite using a wide range of intraluminal ear plugs. The shower caps are best avoided in children because of teasing.
