A prospective study involving 24 centers and 145 patients was conducted to evaluate the long-term osseointegration survival rate for titanium implants anchoring a craniofacial prosthesis (auricular, orbital, or nasal) and to evaluate the long-term retention and stability of the prosthesis. Of 452 implants placed, 19 were lost (overall survival rate of 96%). Of the 145 patients, 115 were evaluated (remained active) throughout the study period and were followed-up for at least 30 months. The results of the study suggest that the bone-anchored craniofacial prosthesis system is a viable alternative to conventional reconstructive surgery and offers significant improvement in the quality of life when compared with the support systems previously available for these types of prostheses.
一项涉及24个中心和145名患者的前瞻性研究开展，以评估用于固定颅面假体（耳廓、眼眶或鼻）的钛植入物的长期骨整合存活率，并评估假体的长期固位和稳定性。在植入的452枚植入物中，19枚丢失（总体存活率为96%）。在145名患者中，115名在整个研究期间接受了评估（仍在参与研究）并随访至少30个月。研究结果表明，骨锚式颅面假体系统是传统重建手术的可行替代方案，与这些类型假体以前可用的支撑系统相比，显著改善了生活质量。
