When performing dorsal reduction in primary rhinoplasty, one must pay close attention to the height of the upper lateral cartilages. They are in part responsible for the dorsal aesthetic lines and often require a lower profile.
The technique the authors describe uses the transverse portion of the upper lateral cartilages rotated medially to function as a local spreader flap while reducing the profile of the dorsum and preserving the aesthetic lines. This is a surgical technique that adjusts the height of the upper lateral cartilages in a precise and safe manner while preserving the function of the internal valve.
The authors present two patients seen at 1 and 3 years after undergoing the autospreader flap technique. In the experience of the senior author (H.S.B.) with this procedure over the past decade, preoperative surgical goals were achieved reliably.
The authors review the anatomical indications in which they found this technique to be simple, reproducible, and effective in shaping the dorsal midvault while preserving the function of the internal valve. Autospreader flap rotation should be considered when dorsal reduction is required.
在初次鼻整形术中进行鼻背降低时，必须密切关注上外侧软骨的高度。它们部分决定了鼻背美学线，且通常需要更低的轮廓。
作者所描述的技术是利用向内旋转的上外侧软骨的横向部分作为局部撑开瓣，同时降低鼻背轮廓并保留美学线。这是一种外科技术，能以精确且安全的方式调整上外侧软骨的高度，同时保留内鼻阀的功能。
作者展示了两位接受自体撑开瓣技术治疗后1年和3年的患者情况。根据资深作者（H.S.B.）在过去十年中使用该手术的经验，术前手术目标均可靠达成。
作者回顾了解剖学适应证，发现在这些情况下该技术在塑造鼻背中拱部时简单、可重复且有效，同时保留内鼻阀的功能。当需要进行鼻背降低时，应考虑自体撑开瓣旋转术。
