Photo-Assisted Anthropometric Analysis of Double Eyelid Blepharoplasty in Young Chinese.

BACKGROUND

Double eyelid blepharoplasty has gained popularity over decades among Asians. Quantitative assessment of the morphologic changes after double eyelid blepharoplasty remains obscure. A photo-assisted digital method was introduced to measure the outcomes of double eyelid surgery in young Chinese.

METHODS

A total of 168 Chinese patients who underwent esthetic upper blepharoplasty were recruited from October 2018 to October 2020. The participants were divided into mini-incision, full-incision, and full-incision double with epicanthoplasty (FIDE) groups. Changes in the eyeball exposure area (EEA), brow eyelid margin distance [brow eyelid distance (BED)], and palpebral crease height after surgery were analyzed using ImageJ software.

RESULTS

There was an overall increase in EEA in the 3 groups after upper blepharoplasty surgery. The FIDE group showed the most increase in EEA among these groups. Furthermore, BED was significantly decreased in each group after upper eyelid blepharoplasty; however, the mini-incision double group showed the least BED reduction. The palpebral crease height at 90 days was significantly lower than that at 7 days after surgery.

CONCLUSIONS

The photo-assisted anthropometric analysis offers a simple and objective measurement for double eyelid blepharoplasty. The eyes appear larger because of the increase in EEA and decrease in BED after double eyelid blepharoplasty. Distinct results were produced by different surgical techniques. The FIDE group showed the maximum increase in EEA and a decrease in BED. These findings provide important references for preoperative planning and postoperative measurement.
