The modiolus is important for facial expressions.
It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.5 turns around its axis, the modiolus.
From the spiral canal of the modiolus numerous canals pass outward through the osseous spiral lamina as far as its free edge.
Studies with preshaped (modiolus-hugging electrodes) have been proven to be not so effective.
The bony canal of the cochlea takes two and three-quarter turns around the modiolus.
A spiral ligament and a cartilaginous process called the modiolus connect and support the cochlear duct to the rest of the cartilaginous structures that surround it.
