Ear, nose, and throat (ENT) specialists are medical doctors who specialize in the diagnosis and treatment of diseases or conditions of the ear, nose, and throat. They may also be called otolaryngologists (say "oh-toh-lair-un-GAWL-uh-jists") or head and neck surgeons.

ENT doctors perform surgery for sinus and sleep problems, remove tonsils and tumours, help with hearing and balance problems, and more. Some ENT doctors also do cosmetic and reconstructive surgery (plastic surgery).

ENT doctors are certified through the Royal College of Physicians and Surgeons of Canada.
