Axial bilobed superficial temporal artery island flap (tulip flap): reconstruction of combined defects of the lateral canthus including the lower and upper eyelids.

摘要

Full-thickness and combined eyelid reconstruction that includes the lateral canthal region is complex and difficult because of the special skin characteristics and the different structures involved, which include the eyelashes, tarsal plate, conjunctiva, lateral palpebral commissure, lateral canthal tendon, and lateral fornix,, To close defects in this region with good texture and color match and to obtain successful functional and aesthetic results, good vascularized skin and soft tissue play an important role. In recent practice, for large, full-thickness eyelid defects that cannot be closed primarily, different free composite grafts and local pedicled flaps have been used for reconstruction.
