Ear, nose and throat physicians are trained in disorders of speech, hearing and balance. In today’s program we will discuss these disorders with Dr. Stephen Schaffer and Dr. Mark Lorenz.

Dr. Schaffer has a specialized interest in voice disorders and his office is the only one in Alaska using a video strobe to diagnose vocal cord or larynx disorders.

Dr Lorenz has special training in complex surgery of hearing and balance disorders. Particularly important is his ability to provide a local option for insertion of cochlear implants which restore some sense of hearing to the deaf and patients with profound hearing loss.
