Petrous Bone Model

Petrous Bone Model for Preparation

• 
• Before starting the training in microsurgery of the middle ear the complex anatomy of the petrous bone makes a extensive training necessary. In cooperation between the department of oto-laryngology, head and neck surgery of the University of Jena and the 3di company an 3-dimensional artificial petrous bone model was developed. The anatomical structures are coloured, good to identify and can therefore be teached intensively.
• Fields of application
  
    ·    education for medical specialists
    ·    courses of instruction / training
    ·    visual aids
