[The value of a previously expanded musculo-cutaneous flap of the lower eyelid for the reconstruction of a full thickness loss of tissue substance of the upper eyelid].

The authors report a new technique for the reconstruction of upper eyelid full thickness tissue losses in preserving the inferior edge. They describe a myo-cutaneous inferior eyelid flap which has been preliminarily expanded before transposition. An anatomical study has demonstrated vascularization and innervation of the myo-cutaneous eyelid flap which will remain active. A clinical case presentation confirms a good aesthetic but also functional result with a transferred active orbicularis muscle which allows the regain of a dynamic upper eyelid.
