Dr. Arnaldo Rivera’s areas of clinical and surgical interest are conditions that affect hearing and balance as well as conditions that affect the skull (lateral skull base). Dr. Rivera cares for patients of all ages with complex tumors and pathology, and he is the only fellowship-trained ear, lateral skull base and implantable hearing device surgeon at MU Health Care. During his tenure in the NAVY, he was the neurotologist at Walter Reed National Military Medical Center and cared for wounded warriors and their families. As such, he treated complex trauma to the lateral skull base and inner ear, giving him a unique perspective in the surgical interventions and reconstructions of this complex anatomy. He is also the program director of the Otology fellowship at The University of Missouri. Since 2009, Dr. Rivera has been a member of the FDA Ear, Nose and Throat Devices Panel of The Medical Devices Advisory Committee. Captain Rivera retired from the NAVY after twenty-eight years of service.
