Pop Quiz #112


The correct answer is C. Ectropion.

Ectropion occurs when the eyelid margin turns outward away from the eye. In lower eyelid reconstruction, tension should be oriented parallel to the lower eyelid to prevent the development of ectropion.

Trap door deformity occurs with scar contraction when flaps elevate above the level of normal surrounding skin.  Hypertrophic scars are those elevated above the level of surrounding skin on any location.  Temporal nerve paralysis is evidenced by frontalis muscle dysfunction and eyebrow ptosis.  Eclabium occurs with the lip margin turns outward from the mouth.
