In particular, the frontal belly of the occipitofrontalis
, the platysma of the face, and the zygomaticus major are connected with the SMAS (Table II).
Shearing or traction forces such as hair pulling lead to rupture of these veins and this space is wide enough to store large amounts of blood albeit limited with attachments of galea aponeurotica (orbital ridges, occipitofrontalis
muscle and zygomatic arches).
Lower fractional anisotropy was found in the right fasciculus occipitofrontalis
, splenium corporis callosi, and posterior cingulate.
The upper part of the orbicularis occuli was exposed and the frontal belly of occipitofrontalis
was followed from below upwards.
