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.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
