Normal hearing after trauma with completely ectopic incus -- how possible?.

ABSTRACT

OBJECTIVES: To report the rare case of a patient with complete incus dislocation after trauma showing normal hearing. METHODOLOGY: 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. CONCLUSION: This case demonstrates that disruption of the ossicular chain does not always require ossicular reconstruction.
