Lower blepharoplasty - Canthopexy and risk of eyes looking smaller.

The reason general plastic surgoens perform canthopexy as a routine part of lower blepharoplasty, is that they perform the surgery through an lower eyelid incision below the lower eyelid lashes. This surgery cuts through the motor nerve that supply the muscle along the edge of the lower eyelid.  That is a very bad thing because it is this muscle that is responsible for holding the lower eyelid against the surface of the eye.  The canthopexy tightens the lower eyelid and tends to partially compensate for the motor damage to the orbicularis oculi. A canthopexy can distort the eyelids shape or it can have a minimal effect on the eyelid.  A better question: is it necessary to have a transcutaneous lower blepharoplasty?  Do you need a transcutaneous lower blepharoplasty?  An alternative is to perform the surgery from behind the lower eyelid using a method perferred by oculoplastic surgeons. Of course an even better question is do you need a lower blepharoplasty at all?  There is no substitute for getting a diversity of opinions.

Canthopexy is not standard and usually not necessary during lower blepharoplasty IF blepharoplasty is performed using transconjunctival technique however there are exceptions. I need to evaluate your eyes to give you definite answer. See following link.

Thank you for your question.  In my experience, when done correctly, a canthopexy does not change the shape of the eyelid at all.  But if the canthopexy stitch is placed too high, then the lid can have a slanted appearance and the eye will look smaller.  I would ask to look at before and after photos of other patients your surgeon has done canthopexys on.

A canthopexy is used for a lower bleph when the patient is at risk for a droopy lower eyelid after surgery. If done correctly, it is not expected to make your eye smaller or shorter looking but rather helps your eyelid hold its natural almond shape. Sometimes swelling immediately after surgery can give the false appearance of a smaller eye. There are many anatomical and functional considerations when deciding if a canthopexy is needed and therefore it is best to have an in-office examination to review your options and the pros, cons, and risks of each.

Most plastic surgeons will do something to support the lower lid if they believe it is at risk for ectropion (pulling down, resulting in show of the white sclera toward the outer corner of the eye). A few ways to mitigate against this complication include:1. Conservative excision of skin and being very careful with handling of the eyelid muscle and orbital septum, layers that provide support and strength to the lid2. Supporting the lid with a small canthopexy suture - there are many individual preferences on how to do this - in order to support the outer corner tissues against something solid like the bone. If done judiciously, like with a single support suture and not too tight a "sling" on the tissues, it does not usually change the shape of the lid at all.3. Being more aggressive with a canthoplasty, where the corner of the lid may even be divided and some extra tissue taken out, with the lid margin tissues used to support the angle of the lid. This is usually only required when patients either have preexisting laxity or as a correction to ectropion that has already occurred from prior surgery
