The inframammary fold (IMF) is an essential aesthetic element that influences the outcome of breast surgery. In this study, we introduced a new method for finding the IMF based on retrospective analysis of chest computed tomography (CT) scans of women's breasts. Sagittal sections of 80 female chest CTs were analyzed. Sagittal sections of 80 female chest CTs were analyzed by a single plastic surgeon. The distances between the fifth, sixth, and seventh ribs and the IMF were measured using Photoshop, and the location of the IMF was statistically analyzed according to age and height using paired t tests and Pearson's correlation test. As determined by our new method, the average distance between the IMF and the sixth rib was 5.33 mm, which was less than that between the IMF and any other rib. The IMF was closest to the sixth rib in all age groups (P < 0.001), and all IMFs were located between 39.5 mm superior and 24 mm inferior to the sixth rib. The sixth rib, one of the most visible reference structures in women's surface anatomy, is the "sentinel rib" for the IMF and the most predictive indicator of the location of the IMF. Knowing the original anatomic location of the IMF will enable better outcomes during breast surgery. Clin. Anat. 33:165-172, 2020. © 2019 Wiley Periodicals, Inc.
乳房下皱襞（IMF）是影响乳房手术结果的重要美学元素。在这项研究中，我们基于女性乳房胸部 CT 扫描的回顾性分析，引入了一种新的寻找 IMF 的方法。由一名整形外科医生分析了 80 名女性胸部 CT 的矢状位切片。使用 Photoshop 测量了第五、第六和第七肋骨与 IMF 之间的距离，并使用配对 t 检验和 Pearson 相关检验根据年龄和身高对 IMF 的位置进行了统计学分析。根据我们的新方法，IMF 与第六肋骨之间的平均距离为 5.33mm，小于与任何其他肋骨之间的距离。IMF 在所有年龄组中都最接近第六肋骨（P<0.001），所有 IMF 都位于第六肋骨上方 39.5mm 至下方 24mm 之间。第六肋骨是女性体表解剖中最明显的参考结构之一，是 IMF 的“哨兵肋骨”，也是 IMF 位置的最具预测性指标。了解 IMF 的原始解剖位置将使乳房手术获得更好的效果。临床解剖学 33:165-172, 2020。©2019 Wiley Periodicals, Inc.
