Objective:
To describe three cases of cochlear implantation utilizing a retrofacial approach to the round window.
Study Design:
Retrospective case review.
Patients:
Three patients with sensorineural hearing loss undergoing cochlear implantation.
Interventions:
Cochlear implantation via a retrofacial approach to the round window.
Results:
Three patients were noted to have inadequate visualization of the round window using a standard posterior tympanotomy at the time of their cochlear implant surgery. A retrofacial approach was performed to provide exposure of the round window to ensure correct placement of the electrode array. Intraoperative photos and postoperative imaging are demonstrated.
Conclusion:
When a laterally or anteriorly positioned facial nerve obscures visualization of the round window, a retrofacial approach is a possible route to visualize the round window.
