Abstract

Cosmetic prosthetics of patients after orbital exenteration remains an urgent problem of ophthalmology and maxillofacial surgery. The process of orbital exoprosthetics is quite complex and requires an interdisciplinary approach with the involvement of a bioengineer, ocularist, ophthalmologist and maxillofacial surgeon. The end result should satisfy primarily the patient, for whom anophthalmos becomes not only a medical but also a psychological and social problem that complicates relationships with people at home and at work. The paper presents a clinical case of orbital exoprosthesis using computer CAD/CAM technology in a 33-year-old patient who underwent exentheration of the right orbit for sarcoma at the age of 2 years. The treatment was carried out in several stages: segmentation of computed tomography data and creation of virtual three-dimensional computer models; creation of design of patient-specific implants as a basis for fixing of an exoprosthesis; surgical intervention - fixation of patient-specific implants; production of exoprosthesis. The postoperative period passed without complications. The results of the treatment fully satisfied the aesthetic requirements of the patient, which allowed her to communicate freely with people and return to a full life.
