Overview
It is generally accepted that Carhart’s “dip” in otosclerosis develops as a result ofthe absence of the middle ear osteotympanic component of the bone conduction due to a block ofthe oval window. In the submitted article the authors summarize reasons which cast doubts on thisview. The authors assume that Carhart’s “dip” oceurs as a result of the mechanical and hydrodyna-mic changes in the cochlea.
Key words:
Carhart’s “dip”, otosclerosis, bone conduction hearing threshold.
