An Otolaryngologist - Head and Neck surgeon ( Ear Nose and Throat Surgeon) is a doctor who specializes in disorders of the head and neck, especially those related to the ear, nose and throat. The specialty encompasses management of ear disease and hearing loss, endoscopic examination of air and food passages, care of nose and sinuses, tumors of the head and neck, laryngeal and thyroid disorders and facial cosmetic surgery. Otolaryngology has thus evolved into a multi faceted specialty caring for patients of all ages who have a variety of disorders of the head and neck.
