  • Abstract
  • Look Inside

 A case of sensory-neural hypoacusis accompanied with typhoid fever in a 24-year-old woman, who complained of hearing impairment in the left ear and continuous high fever (38-40℃), was reported.

 Clinical examinations showed positive Widal reaction (×640) and leukopenia, and she was diagnosed as typhoid fever.

 Audiological tests revealed TTS (+), TTD (-), and 30% speech discrimination score. In electrocochleography, the patterns of AP and CM showed low amplitudes and high thresholds.

 With recovering of typhoid fever, her hearing was improved and the normal AP and CM responses were recorded.

 We concluded that hearing impairment during the course of typhoid fever was due to some reversible damages of the neural and cochlear elements by enclotoxins.
