All ptosis procedures may be classified into five groups: (1) simple resection of the skin and/or orbicularis, (2) operations utilizing the superior rectus muscle, (3) operations utilizing the frontalis muscle, (4) operations enhancing the effect of the levator muscle, and (5) procedures which artificially suspend the lid, as in suturing it to the orbital wall.

The first group is without permanent effect, and the fifth group is dangerous in that a lid suspended high enough to correct the ptosis will not protect the cornea and will not follow the eye on looking down.
