What They Do
An ENT specialist, formally known as an otolaryngologist, is a physician who diagnoses and treats conditions affecting the ear, nose, and throat, along with related structures of the head and neck. ENT is one of the broader medical specialties in terms of the range of conditions and age groups it covers.
What They Treat
ENT specialists manage a wide range of conditions, including hearing loss, ear infections, sinus problems, nasal congestion and structural nasal issues, voice and throat disorders, and swallowing difficulties. Many ENT specialists also treat conditions of the head and neck more broadly, including certain tumors and issues affecting the thyroid gland or salivary glands, and some further subspecialize in areas like pediatric ENT or head and neck surgery.
Training Path
Becoming an ENT specialist requires completing a medical degree, followed by dedicated residency training specifically in otolaryngology, which covers both the medical and surgical aspects of ear, nose, and throat conditions. This dual medical-surgical training is somewhat distinctive compared to many other specialties, which tend to separate more clearly into either medical or surgical tracks.
When to See One
People commonly see an ENT specialist for symptoms such as persistent ear pain or hearing changes, chronic sinus congestion, persistent sore throat or hoarseness, or difficulty swallowing. ENT specialists are also frequently involved in evaluating balance issues, since balance is closely linked to structures within the inner ear.
Background
Otolaryngology developed as a combined specialty in the late 19th and early 20th centuries, bringing together what had previously been more separate areas of focus on the ear, and on the nose and throat. The combination reflects how closely connected these structures are anatomically, and the field has continued to expand over time, incorporating advances in areas such as hearing implant technology and minimally invasive sinus surgery.
