3D-simulator for studying the structure of the facial nerve channel in othosurgery

[Otorhinolaryngology]

The frequency of the facial nerve damage in otological surgery varies from 0.2 to 10 % and ranks second among the causes of lesion of the facial nerve. The aim of the study was to reduce the number of complications in the middle ear surgery by training of surgical skills on the 3D-simulator of temporal bone. 3D model was produced by the program «Slicer 3D», all the elements were detailed. The model was printed on a 3D printer in liquid plastic. During the printing process the facial nerve channel was contrasted with a plastic of differed color. The above method of manufacturing a phantom of the temporal bone with contrast staining of the facial nerve channel was applied for surgical skills training for three forthcoming surgery in patients with purulent diseases of the middle ear. The total conformity of the temporal bone 3D-simulator and the topographic-anatomical structures of the patients’ middle ear was revealed in all cases. Iatrogenic injuries were not observed
