The Modified Stenver’s View for Cochlear Implants – What do the Surgeons Want to Know?

Despite developments in electrophysiological testing, imaging remains the standard method to determine cochlear implant positioning. Whilst cone beam computed tomography is optimal, modified Stenver radiographs are easier to perform and are therefore commonly used. With recent debate as to the need for routine imaging in uncomplicated cases, the radiologist is increasingly faced with cases of abnormal anatomy or surgical error. The primary interest is the positioning of the electrode array within the cochlea. This includes evidence of tip roll over or kinking and depth of electrode insertion, as both are independent predictors of hearing outcomes and may necessitate revision surgery.
