Canthopexy can be undone and insurance could/should pay for future surgeries

It's relatively simple to undo the canthopexy which was done in an attempt to improve your situation.

To clarify, lagophthalmos is the inability of the eyelids to close completely. This commonly occurs after nerve damge, as is the case with you. The upper eyelid is being managed with the eyelid weight but the lower lid still is drooping because the nerve to the muscles that hold up the cheek are compromised from your brain surgery.

So, now we need to find the best way to get your lower eyelid and cheek back into a higher position so that your appearance is improved but more importantly, so that you can close your eyes. There are various ways to accomplish this depending on what is discovered on physical examination. Some version of a cheeklift plus eyelid tightening surgery is indicated.

Insurance is likely to cover this as the need for this repair was created from your brain surgery. The amount that they will pay will vary depending on your coverage, copays, deductibles, etc.

In addition to treatment of the upper eyelid, it may be wise to resuspend the lower eyelid via a cheeklift, especially if a canthopexy has failed in the past.

With facial paralysis, the orbicularis (eye closing) muscle is deactivated. The cheek droops, literally like a weight dragging down the lower eyelid. Canthopexy or canthoplasty (especially if the lower eyelid is lax) is helpful but we have achieved our best results combining them with a cheek resuspension such as the USIC (ultrashort incision cheeklift).

This is also a good time to critically analyze the asymmetries of the eye, determine which are correctable, and address them.

Your problem is very technical and my colleagues have raised many excellent points and possible methods of repair.

Whatever the repair, no surgery reestablishes the nerve supply to the orbicularis muscle, so perfection, while a nice goal, is not realistic.
