In this prospective study, 34 adults underwent perimodiolar cochlear implantation with an extended round window approach. Three investigators reviewed fluoroscopic, electrocochleography (ECochG) and video data recorded simultaneously during the surgeries. Surgical complexity was also recorded as straightforward or complex. Residual hearing loss was recorded at least 6 weeks after the surgery and was correlated with the impact of surgical complexity on the hearing loss. The authors found that higher surgical complexity was associated with residual hearing loss during the implant procedure and was supported by low (ECochG) amplitudes recorded during complex surgeries.
