Reconstruction of lower eyelid retraction or ectropion using a paranasal flap

This report aims to describe a paranasal flap technique for reconstruction of lower eyelid retraction and ectropion.

After the contracture of the lower eyelid skin or conjunctiva had been thoroughly released, the ipsilateral upper pedicle paranasal flap was designed according to the size of the lower eyelid skin wound. After dissection of the flap, the subcutaneous tissue of the flap was trimmed according to the depth of the wound, the flap was rotated to cover the defect, and an anchor was fixed to the distal aspect of the outer canthus. The secondary defect of the donor area was sutured directly.

In this study, 67 patients with lower eyelid defects resulting from correction of eyelid retraction and ectropion were reconstructed using paranasal flaps between April 2004 and October 2009. The sizes of the paranasal flaps ranged from 0.6×2.2 to 1.5×3.5 cm. At the follow-up assessment, the patients could close their eyes easily and completely without lagophthalmos, and neither the upper lips or the nasal ala showed any anatomic deformities. The features of the paranasal flaps, such as skin color, texture, and contour of the repaired tissue, were a good match with the surrounding skin. The suture lines of the donor areas were sheltered well.

Paranasal flaps were used for effective reconstruction of lower eyelid retraction or ectropion, with achievement of good eyelid function and a good color, contour, and texture match with the surrounding skin. Overall, the functional and cosmetic results were satisfactory.
