摘要：INTRODUCTION: Treacher Collins Syndrome (TCS), a rare autosomal dominant disorder, primarily affects the development of facial structures. Although surgical reconstruction is the treatment of choice for auricular deformities that result from TCS, the implant-retained auricular prosthesis must be considered when surgical reconstruction is not possible. CASE REPORT: In this case report, reconstruction of the bilateral congenitally missing ears of a patient resulting from TCS with implant-retained facial prosthesis was described. Three extraoral implants were placed at bilateral defect sites. After 3-month healing period, osseointegration was confirmed manually objectively by means of resonance frequency analysis. Implant-retained silicone auricular prostheses with bar-clips attachments were fabricated. Follow-up examination was carried out every 6 months. CONCLUSION: After 4 years of function, implants were successful, however deterioration of the prosthesis was observed and replacement prostheses were provided. Prosthetic rehabilitation of the patient resulted in acceptable functional and cosmetic results and enabled the patient return comfortably to society.
