Island mucochrondrocutaneous flap for reconstruction of total loss of the lower eyelid.

The methods usually employed for reconstruction of total lower eyelid loss include (1) tarsoconjunctival flaps from the upper eyelid and skin-graft cover and (2) chondromucosal grafts and local skin-flap cover. We report a technique for coverage of these defects with an island flap involving the full thickness of the ipsilateral nasal wall based on the dorsal (external) nasal vessels, terminal branches of the ophthalmic vessels. The advantages of this method are (1) the main components of the eyelid (skin, tarsus, conjunctiva) are reconstructed in a single short operation, even under local anesthesia, (2) there is one donor area that can be closed primarily without significant deformity, (3) the upper lid remains intact, and ectropion is improbable, and (4) the procedure involves a short hospitalization. As disadvantages we might mention bulkiness of the new eyelid and difficult dissection of the (subcutaneous) pedicle.
