Input: Abstract: A prospective bacteriological and symptomatic study was carried out on 50 swimmers and 50 non-swimmers who had grommets inserted for secretory otitis media. The risk of developing otorrhoea with positive bacterial pathogens was similar for swimmers (7.9%) and non-swimmers (8.0%). Subdividing the non-swimmers into 'wetters' and 'strictly dry' there was a similar risk of ear symptoms and pathogens. All children who swim before the insertion of grommets should continue to do so postoperatively with no added risk of ear infections.

Bacteriological aspects of swimming with grommets.
