Techniques for improved visibility and lid protection in orbital explorations.
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.
