Visualization during exploration of the orbit is hampered by herniation of orbital fat around the malleable retractor in posterior orbital dissection. A thin stiff disc of plastic sheeting, placed between the dissected orbital soft tissue contents and the malleable retractor, reduces prolapse of fat around the edges of the orbital retractor. The technique is utilized in acute fracture treatment and in late orbital reconstruction. The malleable retractor, placed below the plastic disc, may be easily taken in and out of the orbit with reduced damage of fat and enhanced visualization. Retractor damage to fat is reduced and visualization enhanced. The plastic sheet may be inserted over an intact posterior bony "ledge" in floor fractures, allowing accurate placement of bone grafts under direct visualization. Additionally, the use of a segment of flexible rubber sheeting sewed over a subciliary incision margin reduces traction injury, drill and cautery damage to eyelid skin.
在眼眶后部解剖中，可塑牵开器周围的眼眶脂肪疝出会妨碍眼眶探查时的视野。在解剖出的眼眶软组织内容物与可塑牵开器之间放置一片薄而硬的塑料片，可减少眼眶牵开器边缘周围的脂肪脱垂。该技术用于急性骨折治疗和晚期眼眶重建。置于塑料片下方的可塑牵开器可轻松进出眼眶，减少对脂肪的损伤并增强视野。牵开器对脂肪的损伤减少，视野增强。塑料片可插入眶底骨折完整的后部骨“嵴”上方，以便在直视下准确放置骨移植材料。此外，使用一段缝在睑缘下切口边缘的柔性橡胶片可减少牵引损伤、钻孔和烧灼对眼睑皮肤的损伤。
