Abstract

Background: The 8th rib cartilage was sometimes insufficient to construct a complete external helix in ear reconstruction for microtia. The aim of this study was to investigate the splicing technique of 8th rib cartilage in modified Nagata method stage I.

Methods: Between September 2022 and May 2023, 231 consecutive patients with microtia underwent auricular reconstruction with modified Nagata method stage I. Thirty-four patients with insufficient 8th rib cartilage were screened out by three-dimensional (3D) computed tomography preoperatively, who were included in the study prospectively. The 8th rib was spliced to create the external helix when fabricating the ear framework in the stage I surgery for the 34 patients. The median duration of follow-up was 12.1 months (8-15 months).

Results: There were no perioperative complications in our study. During follow-up, all patients had satisfying outcomes, with no inward collapse, displacement, or absorption of the spliced external helix. The splicing point was not obvious.

Conclusions: It was safe and effective to splice the 8th rib cartilage for external helix of the cartilage framework in ear reconstruction for microtia.

在改良长田法第一阶段中拼接螺旋框架，用于第八肋软骨不足患者的耳廓重建。

背景：在小耳畸形的耳再造术中，第 8 肋软骨有时不足以构建完整的外螺旋。本研究旨在探讨改良长田法 I 期第 8 肋软骨的拼接技术：方法：2022年9月至2023年5月期间，连续231例小耳症患者接受了改良长田法I期耳廓重建术，术前通过三维（3D）计算机断层扫描筛选出34例第8肋软骨不足的患者，将其纳入前瞻性研究。在为这 34 名患者进行第一阶段手术时，在制作耳廓框架时拼接了第 8 肋骨以形成外螺旋。中位随访时间为12.1个月（8-15个月）：结果：我们的研究未发现围手术期并发症。结果：我们的研究中没有出现围手术期并发症，所有患者的随访结果均令人满意，没有出现拼接外螺旋向内塌陷、移位或吸收的情况。接合点不明显：在小耳畸形耳再造术中，用第8肋软骨拼接软骨框架外螺旋是安全有效的。
