The use of 3D printed paediatric temporal bones as a training tool

Abstract

Introduction: Temporal bone dissection is an essential component of otological training. The ideal temporal bone training platform should allow the surgeon to prepare and undertake the actual operative procedure required prior to the operation on the patient. Paediatric temporal bones are generally not available or used due to ethical issues and availability.

Methods: Using specialised computer programmes and non-identifiable paediatric high resolution computed tomography (HRCT) scans of temporal bones 3D printing of paediatric temporal bones has been trialled.

Results: 3D printing of paediatric temporal bones has proved both an economical and anatomically accurate tool for training. Using HRCT scans to print from allows cases of appropriate complexity to be selected.

Conclusion: 3D printed temporal bones from HRCT images provide optimal opportunities for paediatric temporal bone training and allow for more accurate delineation of structures. Furthermore, they provide improved haptics through choice of appropriate material, especially in complex cases and where anatomy may be difficult.
