During the period February 1989-September 1991, 15 patients with absent or defective pinna were treated with a bone-anchored auricular prosthesis at the ENT-department, Rigshospitalet, Copenhagen. These patients were followed up from the hospital records and by means of a questionnaire. Altogether 40 titanium implants have been inserted, of which one implant was found not to be integrated at the time of the second-stage surgery. Five patients underwent additional surgery, one patient because of non-integration of a screw, and four patients on account of soft-tissue reactions. From the questionnaire replies it appears that all patients found the cosmetic result and the technique concerning mounting of the prosthesis very satisfactory. Nearly half the patients found that the care of the skin around the abutments caused considerable problems. Three patients had experienced unintended losses of the prosthesis. In conclusion, treatment with a bone anchored auricular prosthesis has considerable advantages compared to treatment with a prosthesis attached by adhesive. Furthermore the use of a bone-anchored prosthesis should be considered a viable alternative to surgical reconstruction because of the outstanding aesthetic result and because the surgical procedure puts less strain on the patient. The disadvantage of the method is the lifelong daily care of the skin and the dependence on the health services.
在1989年2月至1991年9月期间，哥本哈根里格霍斯医院耳鼻喉科对15名耳廓缺失或有缺陷的患者进行了骨锚式耳廓假体治疗。通过医院记录和问卷调查对这些患者进行了随访。总共植入了40枚钛植入物，其中1枚植入物在二期手术时未融合。5名患者接受了额外手术，1名患者是因为螺钉未融合，4名患者是由于软组织反应。从问卷调查的回复来看，所有患者对假体的美容效果和安装技术都非常满意。近一半的患者发现基台周围皮肤的护理带来了相当大的问题。3名患者经历过假体意外脱落。总之，与使用粘合剂固定的假体治疗相比，骨锚式耳廓假体治疗有相当大的优势。此外，由于出色的美学效果以及手术过程对患者的压力较小，使用骨锚式假体应被视为手术重建的可行替代方案。该方法的缺点是需要对皮肤进行终身日常护理且依赖医疗服务。
