Defect of 75 to 100% of the lower eyelid may
be reconstructed using the following techniques:
-
two-stage tarsoconjunctival flap proedure with full thickness
skin graft (Hughes's flap):
-
first stage is the creatio of a tarsoconjunctival flap, the
horizontal incision
is parallel to the lid margin and at least 4 mm above
the inner surface margin. After suturing the flap to the defect, the area
is covered with a skin graft
-
second stage: 6 to 9 weeks after the first stage, the palpebral
fissure is
opened by dividing the flap and create a conjunctiva
lined lid margin
