Ultralong pedicled superficial temporal fascia island flaps for lower nasal defect.

摘要

To explore the method of repairing nose defects of apex, ala, septum, and even opposite ala nasi with ultralong pedicled superficial temporal fascia (STF) island flaps. There were 29 cases with defects of apex nasi, ala nasi, and nasal columella, of which 12 cases were repaired with frontal-branched STF island flaps, 14 cases with apical-branched STF postauricular island flaps, and 3 cases with prefabricated apical-branched STF postauricular island flaps. The flap areas were arranged from 1.2 x 2.3 to 2.0 x 2.8 cm2; the length was more than 15 cm on average. Liners were reconstructed at the stage of prefabricating flaps with free skin graft in the cases of ala nasi defects. The surfaces of wound after flap prefabrications were covered by skin graft as well. Twenty-seven cases were successfully taken without blood circulation blocks; the color, texture, and figure were good, and the outcomes were satisfying. Seven nonprefabricated flap cases have epidermis necrosis because of the lack of artery perfusion pressure and venous return handicap, and the epidermis fell off after 1 month, 2 cases of which required secondary surgery because of partial necrosis. Ultralong pedicled STF island flap is an available way to repair defects of apex nasi, ala nasi, and nasal columella. Prefabricated flaps are with benefits of good blood circulation, primary-made liner, and minute injury of the donor site. It is a good method to repair defects of apex nasi, ala nasi, nasal septum, and opposite ala nasi simultaneously.
