The objective of the present study was to develop and introduce into the clinical practice the method for the combined aesthetic and functional rehabilitation of the patients presenting with congenital atresia of the external auditory canal (CAEAC) and the concomitant microtia. A total of 8 patients at the age from 6 to 21 years with unilateral CAEAC and microtia were given the surgical treatment. During the intervention, atresia was resolved using the trans-mastoid approach, tympanoplasty of autofasciae and ossiculoplasty making use of the partial titanium prosthesis and the placement of cranial osteointegratable titanium implants. At the second stage of the surgical intervention the 3D silicone prosthesis of the auricle shaped on an individual basis were used. The long-term follow-up observations have demonstrated the stable formation of the tube of the external auditory canal, with the bone-air interval amounting to 15-20 dB. The auricular prosthesis was the mirror image of the natural ear and completely concealed the congenital defect.
本研究的目的是开发一种用于先天性外耳道闭锁（CAEAC）并伴有小耳畸形患者的美学与功能联合康复方法，并将其引入临床实践。共有8例年龄在6至21岁的单侧CAEAC和小耳畸形患者接受了手术治疗。在干预过程中，采用经乳突入路解决闭锁问题，使用自体筋膜进行鼓室成形术，并利用部分钛质假体进行听骨成形术，同时植入可与颅骨骨整合的钛植入物。在手术干预的第二阶段，使用根据个体情况定制的3D硅胶耳廓假体。长期随访观察表明，外耳道管腔形成稳定，骨导-气导间距为15-20dB。耳廓假体是自然耳的镜像，完全掩盖了先天性缺陷。
