The aims of this study were to evaluate the success rates and peri-implant soft tissue responses of auricular implants, to assess prosthetic complications, and to calculate the survival rate of silicone auricular prostheses. Twenty-nine extraoral implants were placed in 10 patients with 11 auricular defects. Implant failure was defined as clinically detectable implant mobility, and a 5-point scale was used to record the health of peri-implant soft tissues. Prosthetic complications were assessed, and the survival rate of silicone auricular prostheses was calculated using Kaplan-Meier analysis. The implant success rate was 100%. A few soft tissue problems were noted. The overall cumulative survival rate for the first prostheses of the patients was 70% after 18 months. The mean survival time was 17 months. Extraoral implants had a very high success rate in the mastoid region. Prosthetic assessment indicated that although experience with wearing prostheses reduces retention degradation, discoloration and reduced quality of fit at the prosthesis edge over time remain the major problems in maxillofacial prosthetics.
本研究的目的是评估耳廓植入物的成功率和种植体周围软组织反应，评估修复并发症，并计算硅胶耳廓假体的存活率。在10例患有11处耳廓缺损的患者中植入了29枚口外植入物。种植体失败定义为临床上可检测到的种植体移动，并使用5分制记录种植体周围软组织的健康状况。评估修复并发症，并使用Kaplan-Meier分析计算硅胶耳廓假体的存活率。种植体成功率为100%。发现了一些软组织问题。患者首个假体在18个月后的总体累积存活率为70%。平均存活时间为17个月。口外植入物在乳突区域的成功率非常高。修复评估表明，虽然佩戴假体的经验可减少固位力下降，但随着时间的推移，假体边缘变色和贴合度下降仍然是颌面修复中的主要问题。
