Otorhinolaryngology (otolaryngology), is the study of ear, nose, and throat (ENT) conditions. The head and neck region contains a number of our sense organs; hence ENT surgeons deal with problems affecting hearing, balance, taste and smell. Since the head/face/neck forms a visible portion of our bodies, surgeons must be cognisant of the cosmetic aspects of their interventions. Procedures such as nose and ear re-shaping form a part of their work-load. Otolaryngologists treat children with a range of problems such as tonsillitis. Adult patients are often treated for sinus infections, age-related hearing loss, and occasionally cancers of the head and neck.
