Abstract：
BACKGROUND: Autologous costal cartilage has gained widespread acceptance as an important material for ear reconstruction in patients with microtia. Despite its recognition as being \"worth the trade-off,\" attention should be directed toward donor-site deformities. This systematic review focused on existing English literature related to microtia reconstruction and aimed to reveal the incidence of chest wall deformities and assess the effectiveness of the various proposed surgical techniques aimed at reducing donor-site morbidities.
METHODS: A comprehensive search was conducted on Pubmed and OVID using the keywords \"microtia,\" and \"chest deformity\" or \"rib harvest.\" Articles were screened based on predefined inclusion and exclusion criteria. Data acquisition encompassed patient demographics, employed surgical techniques, methods for evaluating chest deformity, and incidence of associated complications.
RESULTS: Among the 362 identified articles, 21 met the inclusion criteria. A total of 2600 cases involving 2433 patients with microtia were analyzed in this review. Perichondrium preservation during cartilage harvesting led to a significant reduction in chest deformities. However, the wide incidence range (0% to 50%) and the lack of specific assessment methods suggested potential underestimation. Computed tomography revealed reduced chest wall growth in the transverse and sagittal directions, resulting in decreased thoracic area. Innovative surgical techniques have shown promising results in reducing chest deformities.
CONCLUSIONS: Although a quantitative analysis was not feasible, objective evidence of deformities was established through computed tomography scans. This analysis highlighted the need for dedicated studies with larger sample sizes to further advance our understanding of chest wall deformities in microtia reconstruction.

摘要：
背景：自体肋软骨已被广泛接受为小骨症患者耳部重建的重要材料。尽管它被认为“值得权衡”，“应注意供体部位的畸形。本系统综述集中于与小骨症重建相关的现有英文文献，旨在揭示胸壁畸形的发生率，并评估旨在减少供体部位发病率的各种拟议外科技术的有效性。
方法：使用关键字\"microtia,\"和\"胸部畸形\"或\"肋骨收获。“根据预定义的纳入和排除标准筛选文章。数据采集包括患者人口统计学，采用手术技术，评估胸部畸形的方法，以及相关并发症的发生率。
结果：在362篇确定的文章中，21符合纳入标准。本综述共分析2600例，涉及2433例小耳畸形患者。软骨收获过程中的软骨膜保存导致胸部畸形的显着减少。然而,广泛的发病率范围(0%~50%)和缺乏具体的评估方法提示潜在的低估.计算机断层扫描显示胸壁在横向和矢状方向的生长减少，导致胸部面积减少。创新的手术技术在减少胸部畸形方面显示出了有希望的结果。
结论：尽管定量分析不可行，通过计算机断层扫描建立了畸形的客观证据.该分析强调了需要进行更大样本量的专门研究，以进一步增进我们对小骨症重建中胸壁畸形的理解。
