The reverse auricular flap for the reconstruction of extended defects of the lower eyelid.

The authors present eight cases of lower eyelid reconstruction after extended excision of cutaneous carcinomata. To recreate the supporting function of the lower eyelid it is necessary to reconstruct a rigid structure, which must replace the tarsus and has to be covered by sufficiently thin skin. A condrocutaneous helix island flap, based on the frontal branch of the temporal artery, allows us to reconstruct both lamellae of the eyelid at the same time. The reverse flow to the flap through this vascular pedicle is assured by the anastomotic branches from the supratrochlear and supraorbital arteries. Using this flap we have been able to recreate morphology and function of the lower eyelid with a good cosmetic result in the donor site as well.
