问题的陈述。硅橡胶面部假体的寿命较短，关于这种类型的康复的公开数据有限。这项回顾性研究的目的是确定假体失败的预测变量，并强调硅橡胶面部假体治疗后的预期结果。材料和方法。在机构批准后，评估了2004年至2015年期间巴西一家机构的患者记录。使用标准化表格收集患者数据。脆弱生存模型（简单随机效应生存模型）用于检验年龄、性别、假体类型、缺损来源、种植体数量和固位类型是否对假体失效率有直接影响（α = 0.05）。耳廓假体是最常制造的假体。在随访期间，共制作了84个假体。面部修复的总存活率为34.5%。颜色改变是最常见的原因（27.38%）。种植体成功率为98.18%。种植体数量接近统计学显著性（P= 0.06），与无种植体和超过2个种植体的患者相比，植入2个种植体的患者失败风险降低。应经常召回患者，以便进行修整，避免重复制作新的假体。设计良好的研究是必要的，以确定更多相关的并发症和因素，导致假体失败。
Statement of problem. The longevity of silicone facial prostheses is short, and published data concerning this type of rehabilitation are limited.Purpose. The purpose of this retrospective study was to identify predictive variables for prosthetic failure and to highlight the results that can be expected after treatment with silicone facial prostheses.Material and methods. After institutional approval, patient records from a single Brazilian institution for the time period 2004 to 2015 were assessed. A standardized form was used to collect patient data. Frailty survival modeling (simple random effects survival model) was used to test whether age, sex, type of prosthesis, source of defect, number of implants, and type of retention have a direct impact on the prosthetic failure rate (alpha=.05).Results. Auricular prostheses were the most frequently fabricated prostheses. Eighty-four prostheses were fabricated during the follow-up period. The overall survival rate for facial prostheses was 34.5%. Color alteration was the most common reason for new prostheses (27.38%). The implant success rate was 98.18%. The number of implants approached statistical significance (P=.06) with a reduced risk of failure when the patient had 2 implants compared with patients with zero implants and patients with more than 2 implants.Conclusions. Patients should be recalled frequently so that retouches can be performed, avoiding the repeated fabrication of new prostheses. Well-designed studies are necessary to identify more relevant complications and factors that lead to prosthetic failure.
