Otology is a branch of medicine which studies normal and pathological anatomy and physiology of the ear (hearing and vestibular sensory systems and related structures and functions) as well as their diseases, diagnosis and treatment. Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. Neurotology, a related field of medicine and subspecialty of Otolaryngology, is the study of diseases of the inner ear, which can lead to hearing and balance disorders.

Training to become and otolaryngologist includes one year of general surgery and at least four years of otolaryngology training. These doctors have acquired the skills necessary to manage throat cancer, masses of the neck, voice and swallowing problems, trauma to the face and neck, ear infections, dizziness and hearing loss.

After completing residency training, these doctors must take a written and oral examination to become board certified. The American Board of Otolaryngology has the role of assuring professional standards of training and knowledge.
