What is a glossary of ENT terms?

The field of otorhinolaryngology, commonly referred to as ear, nose, and throat (ENT) medicine, uses a wide range of specialized terminology to describe diseases, procedures, and equipment used for diagnosis and treatment. An ear, nose, and throat doctor also diagnoses and treats conditions affecting the head and neck and can perform both nonsurgical and surgical treatments.

Our glossary is an extensive resource crafted to serve as a reference guide to the various terms used within the ENT field. With terminology defined in clear, easy-to-understand language, this guide is valuable for anyone working in a healthcare setting that intersects with ENT, from doctors, nurses, and students. This ENT glossary includes terminology on:

Terms used to describe the symptoms and signs commonly encountered in ENT medicine are also included. This includes common terms such as otorrhea (ear discharge), epistaxis (nose bleeding), dysphagia (difficulty swallowing), and otalgia (ear pain), as well as specific ENT symptoms like hearing loss, tinnitus (ringing in the ears), and vertigo.
