Blepharoplasty in senile blepharoptosis: preoperative measurements and design for skin excision.

Abstract

For patients with senile ptosis, aesthetic blepharoplasty can be combined with ptosis surgery. However, the amount of skin excision necessary in blepharoplasty is not clearly defined by measurements of the upper eyelids. The authors preoperatively evaluate the amount of skin to be excised in blepharoplasty. Fifty patients with bilateral senile ptosis were included in this study. The amount of skin to be excised from the upper eyelids was selected based on preoperative measurements of redundant skin, equivalent to the maximum lid height (MLH) while manually stretching the eyelid upwards minus resting lid height (RLH) with the eyes closed passively. Ptosis surgery (such as plication of the aponeurosis) followed blepharoplasty. Preoperatively, mean MLH was 35 mm on the right and 36 mm on the left. Mean RLH was 25 mm bilaterally. The mean amount (height) of excised skin was 10 mm on the right and 11 mm on the left. At six months postoperatively, mean MLH and RLH were 29 and 23 mm on both sides, respectively. Significant differences between pre- and postoperative MLH and RDH were seen on both sides (P<.001). No complications due to overexcision were observed, but revision was performed for two patients with asymmetry of the lid folds and five patients with recurrence of drooping. Preoperative measurements of upper eyelid heights (stretched and at rest) appear useful in determining the amount of skin excision required in blepharoplasty for senile ptosis. 4.
