title: Width of the levator aponeurosis is broader than the tarsal plate.
abstract: The aim of this study was to compare the width of the levator aponeurosis and tarsal plate in different levels grossly and histologically. Twelve eyelids of 6 Korean adult cadavers were used. Ten eyelids were dissected, and 2 were prepared for histologic study. Widths of the tarsal plate at its lower border, midheight, and upper border were 21.8 ± 1.8, 16.2 ± 1.6, and 8.3 ± 1.0 mm, respectively. The widths of the levator aponeurosis at the lower border, midheight, and upper border of the tarsal plate were 32.0 ± 2.2, 29.2 ± 3.5, and 27.2 ± 3.9 mm, respectively. Its width was 19.9 ± 4.3 mm at the anterior border of the superior transverse ligament. The width of the levator aponeurosis was broader than tarsal plate at all 3 levels. The medial brims of the levator aponeurosis at the lower border, midheight, and upper border of the tarsal plate were 3.6 ± 1.1, 5.1 ± 1.0, and 6.2 ± 1.1 mm, respectively. The lateral brims of the levator aponeurosis at the lower border, midheight, and upper border of the tarsal plate were 6.6 ± 0.9, 7.9 ± 2.6, and 12.7 ± 3.7 mm, respectively. The width of the levator aponeurosis is broader than the tarsal plate at all levels. This result might be useful in upper-eyelid surgery.
