OBJECTIVES/HYPOTHESIS: Vertical locations of vocal fold mucosal lesions (VFMLs) vary along the free edge. As the vertical contact area of vocal folds (VFs) depends on the vocal register, lesions may occur in the contact area of more frequently used vocal registers. This study investigated the cause of location variations by comparing the vertical sites of VFMLs in singers of both sexes with different music genres.
Retrospective review.
Sixty professional classical and rock singers (11 male classical [M-classical], 22 male rock [M-rock], 13 female classical [F-classical], and 14 female rock [F-rock] singers) who underwent microlaryngeal surgery for VF polyps and nodules and their 108 lesions were enrolled. The VF free edge was vertically divided into three equal parts and classified into the following four lesion sites: upper, middle, lower, and multiple sites.
Upper lesions were most common among F-classical singers (73.9%), whereas lower lesions were most common among M-classical (90.0%) and M-rock (60.6%) singers. Among lesions localized to a single site, lower lesions were most common among F-rock singers (37.0%). F-classical singers had significantly more upper lesions than the other groups (P < .001). M-classical singers had significantly more lower lesions than female singers of any genre (P < .001).
Upper lesions were most common among F-classical singers who mostly used the head voice. Lower lesions were most common among singers who mainly used the modal voice. This study suggests that sex, the dominant vocal register used for singing, and mechanical stress on VFs influence the vertical site of VFMLs.

目的/假设：声带黏膜病变（VFML）的垂直位置沿游离缘变化。由于声带的垂直接触面积取决于发声类型，病变可能发生在更常用发声类型的接触区域。本研究通过比较不同音乐类型的男女歌手的 VFML 垂直位置，探讨了位置变化的原因。
回顾性研究。
招募了 60 名接受显微喉镜手术治疗声带息肉和小结的专业古典和摇滚歌手（11 名男性古典歌手[M-classical]，22 名男性摇滚歌手[M-rock]，13 名女性古典歌手[F-classical]和 14 名女性摇滚歌手[F-rock]），共 108 个病变。将声带游离缘垂直分为三等份，分为四个病变部位：上、中、下和多个部位。
F-classical 歌手的上病变最常见（73.9%），而 M-classical 和 M-rock 歌手的下病变最常见（90.0%和 60.6%）。在单一部位定位的病变中，F-rock 歌手的下病变最常见（37.0%）。F-classical 歌手的上病变明显多于其他组（P<.001）。M-classical 歌手的下病变明显多于任何类型的女性歌手（P<.001）。
上病变最常见于主要使用头声的 F-classical 歌手。下病变最常见于主要使用真声的歌手。本研究表明，性别、唱歌时主要使用的发声类型以及声带的机械应力影响 VFML 的垂直位置。
