These slides are from the Eyelid Surgery Study Group symposium in July 2016. Let me start with the epicanthal fold itself.
The epicanthal fold blocks the medial canthus, as in figure A. After medial epicanthoplasty, the medial corner opens up, like figure B. This was cited from the paper below.
But if the medial release is overdone, the eye looks unnatural.
The technique I described aims for the medial corner to open without overcorrecting, so the result stays natural.
These slides are from the lecture. When the lacrimal lake is overly exposed, an epicanthal-fold restoration like the one below cleans it up. (See my 2014 talk for reference.)
Epicanthal folds come in many shapes.
Treating a complication is much harder than preventing one in the first place.
2016 was a busy year.
