Correction of eyelid retraction using a half-thickness tarsal flap for lengthening of the eyelid following ptosis surgery

Abstract

Various surgical procedures for correction of upper eyelid retraction have been reported, many of which have had favorable results. However, most of these reports are concerned with the correction of upper eyelid retraction in patients with thyroid ophthalmopathy, and few have focused on upper eyelid retraction caused by overcorrection during ptosis surgery. Corrective surgery for upper eyelid retraction resulting from ptosis surgery is often difficult because of the extensive irregular contracture caused by scar tissue. However, as this is a repeat surgery following ptosis surgery, it is important to ensure good postoperative evaluation indices, particularly favorable symmetry, appropriate palpebral fissure width, appropriate crease height, and natural-looking parabolic eyelid margins. Here, we report the lengthening of the upper eyelids using a half-thickness tarsal flap to address upper eyelid retraction secondary to ptosis surgery. By using a half-thickness tarsal flap, the anatomy of the levator insertion onto the tarsal plate is retained, so that good eyelid contour can be obtained, and the results are quantitatively reproducible. Therefore, this technique can be considered for the treatment of upper eyelid retraction and has a potentially wide range of applications.
