GM is a 59-year-old female with a 10- to 15-year history of gradual bilateral progressive hearing loss. In June 2010 GM was hospitalized for several days for an acute episode of severe vertigo. Her balance was markedly impaired, and when she was discharged from the hospital she was using a walker to ambulate (i.e., walk). Prior to the vertiginous attack, GM began noticing increased difficulty hearing in her right ear. She was given prednisone but did not notice any improvement in her hearing. While GM was in the hospital, magnetic resonance imaging (MRI) was completed and was reported as “unremarkable.” Her balance gradually improved in the following months but never returned to “normal.” She was referred to physical therapy to address her chronic issues with balance but did not feel she received any benefit from the therapy. Over the next 2 years the hearing in her right ear rapidly declined, and she was fit with a left bilateral contralateral routing of the signal (BICROS) hearing aid.
