Trial Title: Prospective Study of Round Window Versus Cochleostomy Approach to CI Surgery

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL

Eligibility Criteria:
Inclusion criteria are:~* 18 years of age or older,~* less than a 10-year duration of deafness in the ear to be implanted,~* primary surgery,~* normal shaped cochleae,~* no retrocochlear pathology, and~* grossly normal cognitive function.~Exclusion criteria are:~* less than 18 years of age,~* prelingual deafness, or~* greater than 10-years duration of deafness in the ear to be implanted;~* prior otologic surgery in the implanted ear (excluding tympanostomy tube placement),~* inner ear malformation present in the ear to be implanted,~* retrocochlear pathology present in the auditory system to be implanted,~* developmental delay or known cognitive impairment, or~* pregnancy.

Study Arms:
- round window (Type: ACTIVE_COMPARATOR): Half of the participants will be randomized to the round window technique of cochlear implant device electrode insertion. Intervention for participants randomized to the round window arm include having the round window technique used for the electrode insertion during the participant's cochlear implant surgery. Participants in this arm of the study will also have a post operative CT scan at about three months after surgery.
- cochleostomy (Type: ACTIVE_COMPARATOR): Half of the participants will be randomized to the cochleostomy technique of cochlear implant device electrode insertion. For the participants randomized to the cochleostomy arm, the surgeon will use a cochleostomy technique for the electrode insertion during the participant's cochlear implant surgery. Participants in this arm of the study will also have a post operative CT scan at about three months after surgery.

Based on this trial design, predict the completion outcome and termination type (if applicable).
