Abstract
Purpose
To examine a part of the levator aponeurosis/levator palpebrae superioris (LPS) muscle that did not have fatty deposits in patients with aponeurotic blepharoptosis. We also analysed the relation between this length and surgical outcome after transcutaneous aponeurotic repair.
Methods
We measured the vertical length from the distal end of the anterior layer of the levator aponeurosis to the most distal point of fatty deposits in the levator aponeurosis/LPS muscle (non-fatty-deposit length) in 94 eyelids. Surgical success was defined as a postoperative margin reflex distance-1 (MRD-1) of 2.0–5.0 mm at 3 months postoperatively. The eyelids were classified into two groups: a surgical success group (group A, 76 eyelids) and an undercorrected group (group B, 18 eyelids). Group A was subdivided according to the evidence of a fatty deposit (group A1, fat present, 70 eyelids; group A2, fat absent, 6 eyelids).
Results
The non-fatty-deposit measurement was significantly longer in group A1 than in group B (p = 0.035). The levator aponeurosis was less advanced in groups A1 and A2 than in group B (both, p < 0.001), and the eyelids in groups A1 and A2 obtained a higher MRD-1 than those in group B (both, p < 0.001).
Conclusions
Eyelids with less fat deposit required less advancement of the levator aponeurosis and obtained more favourable surgical results. Intraoperative findings of eyelids with and without fatty deposits and measuring the non-fatty-deposit length may be useful predictive parameters for outcomes of transcutaneous aponeurotic repair.
