ENT Terminology

What's in the 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 and concepts to describe diseases, procedures, and equipment used for diagnosis and treatment.

Our glossary is an extensive resource crafted to serve as a reference guide to the terminologies within the ENT field. With terms 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 to allied health professionals.

The following are included in this glossary:

Anatomy and physiology terminology

ENT deals with some of the human body's most delicate and complex structures. Thus, a critical part of the glossary involves ear, nose, throat anatomy, and physiology terminologies. This includes definitions for structures like the Tympanic Membrane (eardrum), vocal cords, hearing and balance nerves, structures of the outer ear, and more. It touches on diverse aspects of ENT-related physiology, involving terms like Eustachian Tube function, Ossicular chain, and Mucociliary Clearance.

Symptoms and signs

The glossary will also comprehensively explain terms used to describe the symptoms and signs often encountered in ENT. 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 Tinnitus (ringing in the ears), and Vertigo.

Diagnostic terms and techniques

This glossary also sought to include them extensively. It contains definitions for common procedures such as Nasal Endoscopy, Audiometry, Tympanometry, and Vestibular Testing, amongst others.

Diseases and conditions

The glossary provides detailed explanations for a host of ENT pathologies, including Otitis Media (middle ear infection), Labyrinthitis (inner ear disorder), Meniere's Disease, Sinusitis, and Pharyngitis (throat inflammation), to name but a few.

Surgical procedures and interventions

ENT specialists often perform several surgical procedures. Expect entries like Tonsillectomy, Septoplasty, Stapedectomy, Cochlear Implants, and many more. These definitions offer brief explanations about what each surgical procedure entails, its indications, and what it aims to achieve.

Medication and treatment-related terms

There are also many definitions related to medications commonly used in ENT, including antibiotics, steroids, antihistamines, and deodorants. ENT-specific treatments such as Ear Microsuction, Epley's Maneuver, Voice Therapy or Myringotomy, and Grommet application are also given due attention.

Common ENT Terminology

The following are some common ENT terms and their definitions:

• Acoustic neuroma: Vestibular Schwannoma is a rare benign (non-cancerous) tumor that grows slowly on the eighth cranial nerve. If large, it can affect hearing and balance.
• Adenoids: A patch of tissue located high up in the throat, behind the nose. They are part of the body's immune system and help filter bacteria and viruses. Adenoiditis occurs when the adenoid glands become infected, producing inflammation.
• Articulation disorder. Inability to correctly produce speech sounds (phonemes) due to imprecise placement, timing, pressure, speed, or flow of movement of the lips, tongue, or throat.
• Assistive devices. Technical tools and devices assist people with emotional disorders or physical complications perform certain tasks.
• Auditory brainstem-evoked responses (ABR). Tests are used to test hearing in infants and young children or for brain functioning in unresponsive patients. They measure the timing of electrical waves from the brainstem in response to clicks or tone bursts in the ear.
• Balance. The ability of the body to maintain equilibrium and remain steady
• Brain stem implant: A device that substitutes for an injured or diseased part of the nervous system to enhance function.
• Cochle Part of the ear that contains both the organ of hearing (the cochlea) and the organ of balance (the labyrinth). It turns mechanical energy from the middle ear into electrical impulses.
• Conductive hearing loss. Disruption in the normal hearing process is often due to problems with the ear canal, eardrum, or middle ear and its little bones.
• Deafness: Complete or partial loss of ability to use or understand language, usually caused by stroke, brain disease, or injury.
• Dyspraxia:  Inability to make a voluntary movement despite having normal muscle function.
• Eardrum: The membrane separating the middle ear and inner ear.
• Hearing aid: A device that amplifies sound and is worn in or behind the ear to help people with hearing loss.
• Larynx: The voice box located in the throat. It contains the vocal cords.
• Laryngoscope: A medical instrument used to examine the larynx or the voice box
• Mastoid: A bony prominence behind the ear.
• Mastoid surgery: A surgical procedure to remove infected mastoid air cells
• Middle ear: The space behind the eardrum that contains the three tiny bones (ossicles) that transmit sound vibrations to the inner ear.
• Motor speech disorders: Inability to exchange information with others due to hearing, speech, and/or language problems caused by nervous system impairment.
• Mouth sores: Irritation and inflammation of the mouth, often causing discomfort or pain.
• Nasal obstruction: Blockage of the nasal passages, making it difficult to breathe through the nose.
• Neurosensory hearing loss: Hearing loss caused by damage to the inner ear's sensory cells and/or nerve fibers.
• Ossicular chain: The chain of three tiny bones in the middle ear that transmit sound from the eardrum to the inner ear.
• Ototoxic drugs: Medications that can damage the inner ear and cause hearing impairment or balance problems.
• Noise-induced hearing loss: Hearing loss caused by exposure to deafening sounds or sounds at various loudness levels.
• Otitis media: Inflammation of the middle ear caused by infection.
• Sensorineural hearing loss: A type of hearing loss that occurs due to damage to the inner ear, the auditory nerve, or the brain.
• Squamous cell carcinoma: A type of cancer that can occur in many parts of the body, including the throat.
• Swallowing disorders: Difficulties in moving food, liquid, saliva, and pills from the mouth to the stomach.
• Throat cancer:  Cancer that develops in the throat, the voice box, or the tonsils
• Tinnitus: A ringing or buzzing in the ears.
• Tonsils: Two small masses of lymphoid tissue located on either side of the back of the throat that help fight infections.
• Vertigo: A sensation of spinning or dizziness.
• Voice disorders: Any condition that affects the voice's pitch, loudness, or quality.
