Ectropion Procedures in Utah
What is entropion?
Ectropion is the medical term used to describe sagging and outward turning of the lower eyelid and eyelashes.
The margin of the eyelid and the eyelashes evert (turn out) .
This rubbing can lead to excessive tearing, crusting of the eyelid, mucous discharge and irritation of the eye.
During blinking, the eyelids normally sweep across the surface of the cornea (Tearing occurs because the eyelids are not able to wipe the surface of the cornea properly to pump the tears into the tear duct.
Most cases of entropion are due to relaxation of the tissues of the eyelid as a result of aging. Some cases result from scarring of the eyelid caused by chemical and thermal burns, trauma, skin cancers, or previous eyelid surgery. Rarely Ectropion can be present at birth if the eyelids do not form properly.

Anatomy & Function of the facial nerve
- The facial nerve (CNVII) has two major divisions and controls the muscles of facial expression, including the frontalis muscle (raises the eyebrows), the orbicularis oculi muscle (closes the eyes), the zygomaticus muscles (raises the angle of the mouth)
- The upper zygomatic branch supplies the frontalis, upper lid orbicularis oculi, corregator supercilli and procerus.
- The lower zyqomatic branch supplies the lower lid orbicularis.
- The nervus intermedius gives off the greater petrosal nerve which carries parasympathetic secretary fibers to the lacrimal gland
