Aims: To assist with the accurate fabrication and localization of a costal cartilage framework for auricular reconstruction, three-dimensional (3D) digital and solid templates including the auricle and guide plate were made for microtia patients. Methods: The computed tomography data of 60 patients with microtia were included. The 3D digital template of the auricle and guide plate on the healthy side was shaped using MIMICS software with graphic image processing and 3D reconstruction technology. The 3D digital template on the affected side was produced by mirror technique and made into a solid template for clinical application. Results: All 60 patients had a good result of the location and the appearance of the constructed auricle. The time of operation was decreased by an average of half an hour. An individualized 3D solid model of the reconstructed auricular template on the affected side was successfully produced and used in auricular reconstruction. Conclusions: The new 3D template of the auricle and guide plate may be a major contribution to the engraving, assembling and localization of the microtia auricle in auricular reconstruction.

“…This system is safe and simple, and saves time during middle and inner ear surgery (18). Furthermore, the advantage of using the suggested technique of intraoperative diagnostics of the facial nerve is especially obvious in cases, when the anatomy of the middle ear is distorted by previous surgery, as well as in cases of malformation of the facial nerve (2,(6)(7)(8).…”

“…This is caused by the anatomic proximity of the facial nerve to the structures of the middle and inner ear (3-5). The facial nerve becomes more vulnerable to injury during repeated (sanifying) surgery on the middle ear, with the presence of dehiscence in the Fallopian canal, during the removal of masses in the middle ear (2,6), in cases of malformation of the middle or inner ear (7,8).Many scientific works study the anatomy of the facial nerve (3-5). Most of them provide a general description of the microtopographic characteristics of the facial canal and, at the same time, lack information on the thickness of its bone walls.…”

Despite the existing possibilities of using modern surgical equipment and modern diagnostic techniques, there is still a risk of damaging the facial nerve during otological surgery (1,2). This is caused by the anatomic proximity of the facial nerve to the structures of the middle and inner ear (3-5). The facial nerve becomes more vulnerable to injury during repeated (sanifying) surgery on the middle ear, with the presence of dehiscence in the Fallopian canal, during the removal of masses in the middle ear (2,6), in cases of malformation of the middle or inner ear (7,8).Many scientific works study the anatomy of the facial nerve (3-5). Most of them provide a general description of the microtopographic characteristics of the facial canal and, at the same time, lack information on the thickness of its bone walls.Intraoperative damage causes paresis (paralysis) of the facial muscles, which leads to a degradation of the patients' quality of life. According to literary sources, during original surgery, the risk of dysfunction of the facial nerve is 0.6-3.7% of cases (9, 10). During repeated invasive surgery, the risk rises up to 4-10% of cases (1,11,12).The appearance of intraoperative facial nerve monitoring allowed identifying the nerve throughout the entire surgery (13-15), since this method of studying the neuromuscular system registers fluctuation of the electric potential of muscles in response to nerve stimulation.Despite considerable success in the development of machines for intraoperative monitoring of the facial nerve, the most important restriction remained, which was related to the fact that the system could not warn surgeons if they were operating near the facial nerve, whi-
