To prevent acute otitis externa AOE in the saturation setting and to decrease the side effects of the 2 acetic acid solution, a modification to the ear prophylactic regimen was implemented by the Diving Medical Officers DMOs of Navy Experimental Diving Unit NEDU in May of 2012. The modification consisted of the use of the Domboro solution once daily, following immersion or after daily hygiene requirements. A retrospective log review was performed over a one year period to determine if the use of Domboro solution one time daily in a saturation dive setting would be as effective with limited or no side effects as the use of Domboro two to three times daily as initially implemented by Dr. E. Thalmann footnote1 and the U.S. Navy Dive Manual regimen footnote2. In this research, a total number of four dives were completed with 48 ears being exposed to the modified regimen. The incidence was noted to be the same as Dr. Thalmann s results from a study in 1974, 0 of the divers developed AOE, but with fewer complaints of unwanted side effects. The results from the modified regimen yielded no complaints as compared to the 0.012 - 0.024 from the previous year s saturation dives. The success of the once daily use of Domboro is likely secondary to the strength of the solution, the success of the divers continuing to use the solution because it has reduced side effects, and the ability to better control the overall saturation chamber environment.
