Otolaryngologists, sometimes referred to as otorhinolaryngologists or ear, nose, and throat (ENT) doctors, are medical doctors who specialize in the diagnosis and treatment of diseases or conditions of the ear, nose, and throat.

Otolaryngologists can prescribe medication and perform surgery for sinus problems, sleep apnea, or to remove tonsils or cancerous growths, for example. Some otolaryngologists also do certain cosmetic procedures to improve appearance.

Otolaryngologists can be board-certified through the Board of Otolaryngology, which is recognized by the American Board of Medical Specialties.
