An otolaryngological tour of Vesalius' De Humani Corporis Fabrica.

BACKGROUND: Andreas Vesalius published his famous anatomy book, De Humani Corporis Fabrica Libri Septum (On the Fabric of the Body in Seven Books), in 1543, with a second edition in 1555. This article explores the importance of this text to contemporary ENT, by demonstrating Vesalius' fresh, precise and hands-on approach to anatomy, and examines how this developed our understanding of ENT. METHODS: A second edition of De Humani Corporis Fabrica, held in John Rylands Library, University of Manchester, was examined in its digitised form and supplemented by secondary texts. RESULTS AND DISCUSSION: Where Vesalius' predecessors were rigid in their interpretation of anatomy, confined to the instruction of the Ancients, Vesalius showed that these teachings could be analysed and built on with careful observation. This is evident in his illustrations of, and annotations on, the skull base, ossicles and thyroid gland.
