A Scalable Model for Human Scala-Tympani Phantoms

In cochlear-implant (CI) insertion experiments, scala-tympani (ST) phantoms are often used in place of in vivo studies or cadaver studies. During the development of novel CI technology, a scaled-up phantom is often desirable. In this paper, we create a scalable model of the human ST by synthesizing published anatomical data and images. We utilize the model to fabricate an accurate, inexpensive, and reproducible ST phantom at a 3:1 scale.
