Dr. Arnaldo Rivera’s areas of clinical and surgical interest are conditions that affect hearing and balance as well as the base of the skull. Dr. Rivera cares for patients of all ages with complex tumors and pathology, and is the only implantable hearing device surgeon at MU Health Care. During his residency training at the National Capital Consortium, and while caring for our wounded warriors as an active duty member of the Navy, he treated complex trauma to the skull base and inner ear. This experience gives him a unique perspective and the surgical interventions to reconstruct this anatomy. It has motivated him to pursue a path as a neurotologist and skull base surgeon. Dr. Rivera is also still active with the Navy as a naval officer.
