Maxillofacial defect is of great concern physically, emotionally, and psychologically for a patient. However, it is an even bigger challenge for a team attempting rehabilitation, as a crucial decision has to be made between surgical approach and/or prosthetic rehabilitation. However, if both are combined, it will result in best of esthetics and function with ease of maintainance, resulting in a sucessful rehabilitation. This case report represents a case of auricular defect rehabilitated with a combination of implants and bar-retained silicone prosthesis.
A 38-year-old male patient with right auricular defect reported with the main concern of esthetic rehabilitation of a lost part of the external ear.
With through evaluation and examination, a diagnosis of acquired partial auricular defect of the right side secondary to trauma was established.
An implant-retained auricular prosthesis was planned for this case. Surgically, three intraoral implants were placed in the mastoid bone, and after healing, bar framework was fabricated and attached. Finally, silicone prosthesis was fabricated and delivered to the patient.
A successful rehabilitation was carried out in this case using implants and bar attachment for retention of the silicone prosthesis. This prosthesis provided excellent retention and restored the appearance and confidence of the patient.
TAKE-AWAY LESSONS: Rehabilitation of the auricular defect can be carried out with surgical approach, which involves multiple surgeries, and still, the results may not be esthetically favorable. Prosthetic rehabilitation is an option, but retention is generally a hindrance. However, implant-retained prosthesis has really paved a way for rehabilitation of the maxillofacial defect esthetically and more reliably. Cone-beam computerized tomography (CT) can be used for planning and evaluation instead of CT, which will save the patient from a lot of radiation exposure. Hence, in the maxillofacial defect, attempts should be made to explore the option of implant-retained prosthesis.
颌面缺损对患者的身体、情感和心理都有着重大影响。然而，对于一个试图进行修复的团队来说，这是一个更大的挑战，因为必须在手术方法和/或假体修复之间做出关键决定。然而，如果将两者结合起来，将在美学和功能方面达到最佳效果，且易于维护，从而实现成功修复。本病例报告展示了一例通过植入物和杆卡式硅胶假体联合修复耳廓缺损的病例。
一名38岁男性患者，右侧耳廓缺损，主要诉求是对外耳缺失部分进行美学修复。
通过全面评估和检查，确诊为外伤继发的右侧后天性部分耳廓缺损。
针对该病例计划采用植入物固位的耳廓假体。手术方面，在乳突骨中植入3颗口腔内种植体，愈合后制作并安装杆状框架。最后，制作硅胶假体并交付给患者。
本病例通过使用植入物和杆卡式固位装置成功实现了硅胶假体的修复。该假体提供了良好的固位效果，恢复了患者的外观和自信。
耳廓缺损的修复可以通过手术方法进行，这涉及多次手术，而且结果在美学上可能并不理想。假体修复是一种选择，但固位通常是一个障碍。然而，植入物固位假体确实为颌面缺损的美学和更可靠修复铺平了道路。锥形束计算机断层扫描（CT）可用于规划和评估，而无需使用传统CT，这将使患者免受大量辐射暴露。因此，在颌面缺损的修复中，应尝试探索植入物固位假体的选择。
