Abstract
PURPOSE: To describe the technique of anterior approach white-line advancement for correction of ptosis. METHODS: Retrospective review of consecutive cases that underwent anterior approach white-line advancement for correction of aponeurotic ptosis. In this technique, the posterior surface of the levator aponeurosis (white line) is accessed through a skin crease incision (anterior approach) and advanced toward the tarsal plate. Surgery was considered successful if the following 3 criteria were simultaneously met: postoperative upper margin reflex distance of ≥2 and ≤4.5 mm, inter-eyelid height asymmetry of ≤1 mm, and satisfactory eyelid contour. Written informed consent was obtained from all the patients and the study was HIPPA compliant. RESULTS: Twenty patients (29 eyelids) were included in this study. Mean postoperative follow up was 1.25 months (1 to 6 months). Mean preoperative margin reflex distance was 0.38 mm (-1 to 2 mm) and the mean postoperative margin reflex distance was 3.16 mm (2 to 4 mm). Eighteen patients (90%) fulfilled the criteria set for success. The patients rated the outcome of surgery as follows: 80% completely satisfied and 20% significantly improved. CONCLUSION: Anterior approach white-line advancement is a hybrid technique that incorporates the principles of both anterior and posterior approach ptosis correction techniques. The posterior surface of levator aponeurosis (white line) is exposed and advanced toward the superior border of tarsal plate with minimal disruption of eyelid anatomy including the orbital septum and preaponeurotic fat pad. Hence, this technique can achieve superior cosmetic results similar to a posterior approach procedure, without the need for a conjunctival incision.
