==== Promotional material ====

**Promotional material** refers to content designed primarily to highlight, advertise, or endorse a product, service, or concept, often with the intention of influencing perception or encouraging adoption. Unlike [[serious academic literature]], promotional material prioritizes appeal and persuasion over scientific rigor or critical analysis.

In the context of [[medical research]] or [[neurosurgery]], promotional material may include:

  * Descriptive articles showcasing new technologies without supporting clinical data
  * Opinion pieces that exaggerate potential benefits while omitting limitations
  * Industry-sponsored content lacking transparency about conflicts of interest

Although such materials can raise awareness about innovations like [[3D printing]] or [[virtual reality]], they must be distinguished from evidence-based publications to avoid misleading conclusions about efficacy or [[patient safety]].
