[Lower lid entropion and ectropion. Indication, technique and key points of "classical" surgical methods]

Lower lid malposition is common, increases with age and leads to impaired optical function of the ocular surface through chronic irritation of the conjunctiva and cornea. Numerous techniques have been described to reposition the lid margin to the globe and secure this position while maintaining intact motility. Some of these techniques have passed the test of time and have reached the status of "classic" standard procedures that need to be in the armamentarium of every oculoplastic surgeon. The aim of this article is to consider the merits of a selection of standard methods for the correction of lower lid entropion and ectropion by describing their indication, technique and key points.
