Upper Eyelid Ptosis Correction with Levator Advancement Using the Levator Musculoaponeurotic Junction Formula in...

Upper eyelid ptosis correction is a challenging procedure. The authors report a novel approach to this procedure that is more accurate and predictable compared with conventional approaches.

A preoperative system of assessment has been formulated to more accurately estimate the amount of levator advancement required. The levator advancement was referenced from a constant landmark: the musculoaponeurotic junction of the levator palpebrae superioris. The factors considered include the amount of upper lid elevation required, the degree of compensatory brow elevation present, and eye dominance. The preoperative assessment and surgical technique are presented in a series of detailed operative videos. The levator advancement is performed as planned preoperatively with final adjustment made intraoperatively to achieve correct lid height and symmetry.

Seventy-seven patients (154 eyelids) were analyzed prospectively in this study. The authors found this approach to be reliable and accurate in predicting the required amount of levator advancement. Intraoperatively, the formula correctly predicted the exact required fixation location in 63% of eyelids, and to within ±1 mm in 86% of cases. This may be used for patients with ptosis of varying severity, ranging from mild to severe eyelid ptosis. The revision rate was 4%.

This approach is accurate in determining the fixation location needed, enabling levator advancement for ptosis correction to be performed with more precision and predictability.
