What is best for blepharoplasty? Stitches (sutures) or glue? Pros and cons for each?

Glue is no magic bullet. Generally it is associated with a depressed scar on the face.  Careful suturing with timing suture removal leads to the best results.

Stitches are more predictable and safer than glue to close the upper blepharoplasty wound. There are two types of sutures, 1) absorbable, 2) nonaborable (usually removed about 1 week after the procedure).  The technique of upper blepharoplasty is what is most important.

Stitches are for sure the best way to close incisions following eyelid surgery. They are much more precise than tissue glue.
