The Notch of Rivinus is a small defect in the posterior edge of the bony annular tympanic ring. The defect is located just superior to the tympano-mastoid suture line in the posterior ear canal. Following identification of the spine of Henle it is possible to follow the tympano-mastoid suture line medially towards the annular ring. At this location the Chorda Tympani Nerve is often identified. Just superior to this the Notch of Rivinus can be seen and the neck of the malleus occupies the notch and often is the superior limit of a tympanomeatal flap. Etymology: Augustus Q. Rivinus, German anatomist, 1652–1723 a deficiency in the tympanic sulcus of the ear that forms an attachment for the flaccid part of the tympanic membrane and the mallear folds. Also called Rivinus' incisure, tympanic incisure.

Notch of Rivinus
Notch of Rivinus is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Notch of Rivinus rather than just read about it. In short: The Notch of Rivinus is a small defect in the posterior edge of the bony annular tympanic ring. The defect is located just superior to the tympano-mastoid suture line in the posterior ear canal.
Key takeaways
- Notch of Rivinus belongs to biology; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Notch of Rivinus to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Notch of Rivinus from memory before moving on to harder problems.
Reference excerpt
Worked examples
Example 1 — a first encounter with Notch of Rivinus
Start with the simplest possible case. Write down what Notch of Rivinus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.
Example 2 — changing one variable
Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Notch of Rivinus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.
Example 3 — an exam-style question
Typical questions about Notch of Rivinus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
Applications of Notch of Rivinus
- In research
- Notch of Rivinus appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
- In technology and industry
- Engineering practice reuses Notch of Rivinus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
- In the classroom
- Notch of Rivinus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anatomy stubs, Ear, so understanding it makes those chapters shorter.
- In everyday life
- Look for Notch of Rivinus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
