An ENT doctor, also known as an otolaryngologist, specializes in diagnosing and treating conditions related to the ears, nose, and throat. They handle a variety of issues, including hearing loss, sinus infections, allergies, and voice disorders. These doctors often perform surgeries and provide medical management for their patients. In addition to treating adults, ENT doctors also care for children with similar conditions. They may work closely with other specialists, such as audiologists for hearing tests or allergists for allergy management. Overall, ENT doctors play a crucial role in maintaining the health of the head and neck region.
