Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient's expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds and helps to localize sounds, especially in conjunction with the other ear. Osseointegrated implants have an important role in the prosthetic reconstruction of patients with craniofacial defects. The main indications of this treatment plan are lack of local tissue for autogenous reconstruction, previous reconstruction failure and selection of this technique by the patient. This paper presents a clinical case and advantages of the osseointegrated implant technique for retention of auricular prostheses.
面部缺损的修复无论是通过手术还是假体修复，都是一种复杂的方式，这取决于缺损的部位、大小、病因、严重程度、年龄以及患者的期望。在存在外耳道的情况下耳廓缺失会影响听力，因为耳廓收集声音并将其导入耳道。耳廓起到共鸣器的作用，略微放大低频声音，并有助于确定声音的来源，尤其是与另一只耳朵协同作用时。骨整合植入物在颅面缺损患者的假体修复中发挥着重要作用。该治疗方案的主要适应证包括缺乏用于自体修复的局部组织、既往修复失败以及患者选择该技术。本文介绍了一例临床病例以及骨整合植入技术在保留耳廓假体方面的优势。
