On the Anatomy of the ‘Hook' Region of the Human Cochlea and How It Relates to Cochlear Implantation

Abstract

Preoperative assessment of the distance between the round and oval windows may direct the surgeon before CI hearing-preservation surgery. CO techniques, especially in 'small' ears, may lead to frequent damage to the inner ear structures. In those cases with substantial residual hearing, CI surgery may be better performed through a RW approach.
