[Incidence of otitis externa following swimming pool attendance--a case study in 6 indoor pools].
A bacteriological study of the microflora in the auditory meatus of patients with otitis externa after swimming in correlation to the water flora was done during winter 80/81. Six indoor-pools (monthly controls ahead had proven unobjectionable water quality) were analyzed daily, while all swimmers were asked to come for otologic examination whenever symptoms of otitis externa appeared. In a control group without otitis externa the auditory canal was inspected and swabs were taken immediately after swimming. The results indicate, that a short term contamination of the ear canal is possible by swimming in water of unobjectionable quality; this however does not necessarily lead to clinical appearances. Since the incidence of otitis externa in our study (0.01%) was not higher than the morbidity rate in nonswimmers, the data support the concept of the multiplex etiology for otitis externa.
