This study aims to review the authors' experience with the lower lateral crura (LLC) transposition flap in an attempt to highlight its advantages, indications, and limitations.
A retrospective study of 37 rhinoplasties (29 primary cases, 7 secondary cases, and 1 tertiary case) was performed. In all of these, an LLC transposition flap was used by inserting the cephalic portion of the LLCs into a subperichondrial pocket between the medial aspect of the remaining rim strip and the vestibular skin, based on the posterior pedicle.
The most prevalent symptom among our patients was nasal external valve dysfunction. Concavity of the LLCs was very common. The LLC transposition flap can correct the LLC deformities with a high rate of patient satisfaction and no need for revision operations.
The LLC transposition flap can overcome the common irregularities of the LLCs and could be applied to primary and secondary rhinoplasties, as well as ethnic noses.
本研究旨在回顾作者使用下外侧软骨（LLC）转位皮瓣的经验，以突出其优点、适应症和局限性。
对37例鼻整形手术（29例初次手术病例、7例二次手术病例和1例三次手术病例）进行回顾性研究。在所有这些手术中，基于后蒂，通过将LLC的头侧部分插入剩余边缘条内侧与前庭皮肤之间的软骨膜下袋中，使用LLC转位皮瓣。
我们的患者中最常见的症状是鼻外瓣功能障碍。LLC凹陷非常常见。LLC转位皮瓣可以矫正LLC畸形，患者满意度高，且无需翻修手术。
LLC转位皮瓣可以克服LLC常见的不规则性，可应用于初次和二次鼻整形手术以及不同种族的鼻整形。
