Intertragic notch
Intertragic notch is a feature of the human ear anatomy. It is a small depression located between the tragus and the antitragus of the ear.
Etymology[edit | edit source]
The term "intertragic notch" is derived from the Latin words "inter", meaning between, and "tragus", referring to the small prominence of the ear. The term "notch" is used to describe the small depression that is found between these two structures.
Anatomy[edit | edit source]
The intertragic notch is located on the external part of the human ear, specifically between the tragus and the antitragus. The tragus is a small pointed eminence of the external ear, located in front of the concha, and projecting backward over the meatus. The antitragus is a small tubercle opposite the tragus and separated from it by the intertragic notch.
Clinical significance[edit | edit source]
The intertragic notch can be used as a landmark in otology, the branch of medicine that deals with the diagnosis and treatment of ear disorders. It can also be used in the placement of hearing aids and other auditory devices.
