Microtia leads to a severe functional and aesthetic handicap. Traditionally, the auricle is often reconstructed with cartilage transplants, which is, however, associated with some partially substantial disadvantages. The authors have instead used implants of porous polyethylene for successful ear reconstruction for years, thus, avoiding some of these disadvantages. A significant benefit for the patient is achieved by simultaneous hearing rehabilitation by the implantation of active middle ear prostheses.
The authors present their surgical concept which allows functional and aesthetic rehabilitation of microtia in children and adolescents in a single operation. In the respective patient collective, audiometric measurements in quiet and noisy environments were conducted pre- and postoperatively, and health-related quality of life was determined using a validated questionnaire.
All patients experienced a substantial hearing gain both in quiet and noisy environments. The evaluation of health-related quality of life showed a significant benefit from the intervention.
Functional and aesthetic rehabilitation of microtia with active middle ear implants and ear reconstruction using porous polyethylene leads to good and reliable long-term results and can increase the health-related quality of life of affected children and adolescents. The main advantage of this concept is the possibility of a single procedure.
小耳畸形会导致严重的功能和美观障碍。传统上，耳廓常通过软骨移植进行重建，然而，这存在一些较为明显的缺点。多年来，作者改用多孔聚乙烯植入物成功进行耳部重建，从而避免了其中一些缺点。通过植入主动式中耳假体同时进行听力康复，为患者带来了显著益处。
作者介绍了他们的手术理念，该理念可在一次手术中对儿童和青少年的小耳畸形进行功能和美观康复。在相应的患者群体中，于术前和术后在安静和嘈杂环境中进行听力测定，并使用经过验证的问卷确定与健康相关的生活质量。
所有患者在安静和嘈杂环境中听力均有显著提高。对与健康相关生活质量的评估显示，干预带来了显著益处。
使用主动式中耳植入物和多孔聚乙烯进行耳部重建对小耳畸形进行功能和美观康复，可带来良好且可靠的长期效果，并可提高受影响儿童和青少年与健康相关的生活质量。这一理念的主要优点是可以通过单一手术完成。
