Several years post epidemic parotitis 765 children were examined to check possible hearing impairment. High peak was the year 1970 with predominant cases of parotitis with meningo-encephalitis in November/December. Boys (70.98%) were preferable attacked by the disease (age 5--7 years). Audiometric investigations were carried out in 359 cases (epidemic 1970) and 101 children (during 1975-1977), who had continuous control of hearing ability during hospital stay. 23 (4.9%) of the children showed impaired hearing (full deafness or high-tone hearing loss). No definite correlation to severity of parotitis, signs of meningo-encephalitis, location of infected glandula or length of sickness could be detected.
