A micro-computed tomography study of round window anatomy and implications for atraumatic cochlear implant insertion
Background: Cochlear implants are increasingly used to improve sound detection in patients
with substantial residual hearing. However, traumatic cochlear implant insertion through the
round window involving upward deviation of the electrode into the spiral ligament, basilar
membrane, and osseous spiral lamina, medial impaction on the modiolus, or interscalar
excursion into the scala vestibuli are associated with lower rates of hearing preservation and
poorer speech perception.
