On the first and second case (children) the deafness was severe perceptive and bilateral; in the first case the perceptive deafness occurred on the eight day while in the second case the forteenth day from the onset of mumps. On the third case (male adult) the deafness was unilateral, sudden with degeneration of vestibular, which occurred during virumia of mumps.
