In this pilot study 2% taurolidin solution was used for irrigation of
infected ears and instillation topically in 10 patients with severe pu
rulent otitis media. The main purpose of the study was to find out whe
ther the application of the taurolidin solution into the middle ear wo
uld cause significant pain or not. A slight increase in local pain was
found sporadically but was not reason for withdrawing the drug. Twelv
e of 13 bacterial species isolated prior to treatment were eliminated
during the trial, with the otorrhea of most patients stopping after ju
st the first instillation. Audiometric evaluations during and 30 month
s after therapy did not reveal any ototoxic side effects. Tinnitus was
not experienced by any patient during therapy. Overall findings demon
strated that local therapy with taurolidin for patients with severe pu
rulent otitis media was very well tolerated and effective bacteriologi
cally. There were also no therapy-related complications or ototoxic si
de effects.
