To assess the effectiveness of osseointegrated implant supported prostheses in the rehabilitation of severe orbital deformity. Retrospective case series. The study collected 6 patients (6 eyes) with severe orbital deformity, who were treated with osseointegrated implant supported prostheses between 2010 and 2016 in Beijing Tongren Eye Center, Beijing Tongren Hospital. Data included demographic characteristics, causes of the deformity, the history of radiotherapy, the site, number and survival of implants, and the ability to wear prostheses. Among the 6 patients, 4 were males, and 2 were females, with a mean age of 27 (16-44) years. The deformity resulted from evisceration or enucleation and radiotherapy for malignancies in 4 patients, from evisceration because of inflammatory pseudotumor in 1 patient, and from enucleation and debridement because of explosion injury and secondary infection in 1 patient. Each patient received 3 implants at the first operation. A total of 18 implants were installed, including 9 placed into the lateral aspect of the supraorbital rim, 6 into the lateral aspect of the infraorbital rim, 1 into the medial aspect of the supraorbital rim, and 2 into the medial aspect of the infraorbital rim. One superior lateral implant failed half a year after implantation, and an additional implant was implanted into the medial aspect of the inferior medial orbital rim for prostheses retention. All the patients were followed up for more than 2 years. No other failures were observed. The soft tissue reaction was acceptable in all patients. All of them were able to wear prostheses with satisfying appearance. Osseointegrated implants provid excellent retention for orbital prostheses. This technique could be used in patients with severe orbital deformity to improve their life quality. .
评估骨结合种植体支持的义眼在严重眼眶畸形修复中的有效性。回顾性病例系列研究。本研究收集了2010年至2016年在北京同仁医院北京同仁眼科中心接受骨结合种植体支持义眼治疗的6例（6只眼）严重眼眶畸形患者。数据包括人口统计学特征、畸形原因、放疗史、种植体的部位、数量和存活情况以及佩戴义眼的能力。6例患者中，男性4例，女性2例，平均年龄27（16 - 44）岁。4例患者的畸形是由于眼球摘除或眼内容剜出术以及恶性肿瘤放疗所致，1例患者因炎性假瘤行眼球摘除术，1例患者因爆炸伤和继发感染行眼球摘除及清创术。每位患者首次手术时植入3枚种植体。共植入18枚种植体，其中9枚植入眶上缘外侧，6枚植入眶下缘外侧，1枚植入眶上缘内侧，2枚植入眶下缘内侧。1枚眶外上侧种植体植入半年后失败，为保留义眼在眶内侧下缘内侧植入1枚额外的种植体。所有患者均随访超过2年。未观察到其他失败情况。所有患者的软组织反应均可接受。他们均能够佩戴义眼，外观满意。骨结合种植体为眼眶义眼提供了良好的固位。该技术可用于严重眼眶畸形患者以提高其生活质量。
