Hemi-orbicularis oculi switch flap for upper eyelid defects.

BACKGROUND: The technique chosen to reconstruct anterior lamellar defects of the upper eyelid requires careful consideration. We modified pre-existing techniques used to reconstruct anterior lamellar defects after tumour resection and have called this procedure a hemi-orbicularis oculi switch flap. METHODS: This musculocutaneous flap is elevated with underlying orbicularis and its base abuts the anterior lamellar defect. The flap, which is half the height of the defect, is elevated and inset to cover the defect. Then, taking into consideration the extensibility of upper eyelid skin, the remainder of the defect and the donor site are closed directly. RESULTS: Five patients with basal cell carcinoma, haemangioma, and xanthoma of the upper eyelid were treated by this method. All flaps survived and complications were minimal. Aesthetically and functionally good results were obtained by this method. CONCLUSIONS: We have developed a surgical method for the reconstruction of anterior lamellar defects of the upper eyelid. The proposed method is technically simple and safe and provides consistent results for a potentially wide variety of upper eyelid tumours.
