ObjectThe goal of the present article was to describe our dissection training system applied to a variety of endoscopic endonasal approaches. It allowed to perform a 3D virtual dissection of the desired approach and to analyze and quantify critical surgical measurements.MethodsAll the human cadaveric heads were dissected at the Laboratory of Surgical NeuroAnatomy (LSNA) of the University of Barcelona (Spain). The model surgical training protocol was designed as follows: 1) Virtual dissection of the selected approach using our own dissection training 3D model; 2) Preliminary exploration of each specimen using the a second 3D model based on a preoperative CT-scan; 3) Cadaveric anatomical dissection with the aid of a neuronavigation system; 4) Quantification and analysis of the collected data.ResultsThe virtual dissection of the selected approach, the preliminary exploration of each specimen, a real dissection laboratory experience and, finally, the analysis of data retrieved during the dissection step was a complete method to training manual dexterity, hand-eye coordination and to improve the general knowledge of the surgical approaches.ConclusionsThe present model results effective, providing a valuable representation of the surgical anatomy as well as a 3D visual feedback, thus improving the study, design and the execution in a variety of approaches. Such system can also be developed as a pre-operative planning tool that can allow the neurosurgeon to practice and manipulate 3D representations of the critical anatomical landmarks involved in the endoscopic endonasal approaches to the skull base.
