[Therapeutic issues in the case of one hearing ear]

The paper presents some important facts relating to the dangerous cases with one remaining functional ill ear. What should one do when a patient presents with a potentially dangerous chronic otitis media and the other ear is absent? The analysis of such dangerous cases with cholesteatoma, more especially those with a labyrinhine fistula and a cases with sudden deafness contralaterally shows that caution and responsibility has to be taken.
