Reconstruction of inferior palpebral defects with expanded skin flaps / 中华医学美学美容杂志

ABSTRACT

Objective To develop new repairing techniques for acquired inferior palpebral region defects. Methods Expanded forehead flaps were used to reconstruct the inferior palpebral defects or post-excision wound surface and the flaps were pedicled with supra-trochlea vessels or ramus frontalis arteriae temporalis superficialis. As for supra-trochlea vessels, contralateral ones were prior to the homolateral ones. The incision site located in the scalp and the major axis of the expander parallel to the forehead. Firstly, the leisions were cut and the subcutaneous tissues loosed to regain the anatomy position of inferior palpebra. Secondly, the expanded flaps were transfered onto the defects by the wound sizes with the supra-trochlea vessels as their pedicles. At last, the pedicles were cut 3 weeks later.For ramus frontalis arteriae temporalis superficialis, the flap was transfered with a subdermal pedicle and the donor site was closed directly. Results There were 10 cases in the present group, 6 for supratrochlea vessels and the 4 others for ramus frontalis arteriae temporalis superficialis. All the flaps survived successfully. 3 cases returned with optimistic outcomes 6 months later. Conclusion The expanded forehead flaps are fit for repairing the inferior palpebral defects, which can successfully avoid ectropion. This technique is very useful for reconstructing the texture of the site of defects.
