Implant-prosthetic rehabilitation and ectoprosthetics of a patient with an extensive defect of the right orbit. Clinical case. Part 1

During operations for the removal of tumors in the maxillofacial region, aesthetic facial defects and functional disorders are formed: disorders of speech, chewing, swallowing and breathing. Removal of the right eyeball and surrounding tissues after combined treatment of basal cell carcinoma of the right orbit led to the formation of a defect that disrupted the patient’s quality of life. Closing the defect by transplanting a combined flap does not make sense in this case. The manufacture of an ectoprosthesis without supporting elements, taking into account the formed anatomy, does not allow to achieve reliable fixation of the ectoprosthesis. The use of adhesive compositions for fixation in this area is extremely limited and rarely used. Rehabilitation of patients with extensive combined defects of the maxillofacial region is carried out using implant-prosthetic structures. A clinical case of ectoprosthetics of the right orbit is presented with a detailed discussion of all aspects of the design, prototyping and manufacture of the prosthesis.
