title: Normal hearing after trauma with completely ectopic incus -- how possible?.
abstract: OBJECTIVE
  To report the rare case of a patient with complete incus dislocation after trauma showing normal hearing.
  
  
  METHODS
  Physical examination, audiometry, CT of temporal bone, and detection during operation.
  
  
  RESULTS
  The incus had become remotely located in the mastoid cavity, but the patient showed normal hearing because fibrous connections had preserved bony continuity.
  
  
  CONCLUSIONS
  This case demonstrates that disruption of the ossicular chain does not always require ossicular reconstruction.
