ectropion
Pronunciation: /ɪkˈtroʊpiɒn/
Outward turning of the eyelid margin that may occur following midface trauma or surgical procedures.
Full Definition
Ectropion represents a complication of facial trauma or surgery involving the midface, where the lower eyelid margin turns outward, exposing the conjunctival surface and potentially causing functional and aesthetic problems. In oral and maxillofacial surgery, this condition may result from inadequate support of the orbital floor during fracture repair, excessive scar tissue formation, or damage to the orbicularis oculi muscle during surgical approaches. Prompt recognition and correction are important to prevent corneal exposure and associated complications.
Usage
Usage note: Distinguish from 'entropion' (inward turning) which has opposite presentation.
