Drooping eyelid after Botox.
This is actually an excellent question.
Of course the most common cause of drooping of the UPPER eyelid is inadvertent injection into the eye lifting muscle, or aggressive forehead Botox, causing the forehead to descend excessively.
However, when Botox is used for the crow's feet area, it can deactivate the orbicularis muscle. this can cause drooping of a borderline weak lower eyelid, or exacerbate cheek droop that a patient has, causing LOWER eyelid drooping. To understand the effect on each of the muscles on cheek and lower eyelid positioning, we have some literature below.
Eyelid droop not a concern if you are only injecting crow's feet
You can be confident that you are at almost no risk for eyelid droop if you are only having your crows’ feet injected. Actually, by injecting the superior aspect of the muscle that causes crow’s feet, you can gain a slight lift to the outside eye area.
The percentages are with you with Botox for crow's feet
Experienced Botox injectors have great success with the crow's feet. As usual, best to be conservative; you can always add more.
Yes, if the forehead injection is not ideal, the Botox can spread downward and cause the muscle that keeps the upper eyelid "up" to weaken and hence the droopy upper eyelid.
This is rare. It can also occur when injecting to position the outer eyebrow. It is possible to raise the outer (towards the ear) portion of the eyebrow by judicious Botox injection. That takes a expert with long experience. If that were done imperfectly, the same problem with the upper lid could occur.
Since you are most concerned with the crow's feet, tackle those first.
Can your eyelids droop with Botox in crow's feet?
Generally, the risk of this should be slight. Brows and upper eyelids can droop with injection in the forehead or the glabella. Accurate evaluation of your face before placement of the product is essential. The droop, called ptosis, is unusual and goes away. We have not seen eyelids droop with the amount of Botox we place in crow's feet. If a large amount is used in already week eye muscle, it could happen. You should be evaluated by a physician who does a lot of these injections.
Crows Feet and Botox
The major risk for eyleid ptosis is usually from Botox injected in the area just below the eyebrow or in the area between the eyebrows. Generally if done by an experienced board certified physician, Botox is virtually 100% safe!
I say slim chance because in medicine we are taught never to say never or no chance.
The muscle that would be affected to cause a lid drop or "quaz" is the Levator Palpebrae. This muscle is pretty far removed from the lateral portion of the orbicularis oculi muscle which is the muscle injected to ameliorate "crow's feet".
In fact of all the areas injected with Botox the crow's feet are probably the safest and least likely to give you problems. It is a good way to dip your feet into the Botox waters.
Can I get a droopy eyelid after Botox injection into the Crow's feet?
Short answer -- you are unlikely to receive any eye-LID or eye-BROW drooping if you only receive Botox in your crow's feet...
Your question does, however, warrant discussion of two rare, but known, complications of Botox...
(1) A drooping eye-BROW may happen when the brow-elevating muscle in the forehead, the Frontalis, receives too high a dose of Botox, or alternatively, if the Botox is sub-optimally placed too low in the forehead. Of note, it may also happen if you have a low set eyebrow to begin with, in which case any Botox to the Frontalis increases the likelihood of a brow droop. A droopy eyebrow from Botox can sometimes be improved with Botox injected into the outside part of the eye (the lateral aspect of the orbicularis oculi muscle) to generate a bit of a brow lift in that area -- by injecting more Botox and paralyzing the orbicularis muscle that normally acts to depress the brow in that area, you may get a slight compensatory brow lift...
(2) A droopy eye-LID may occur if the Botox is injected too close to your eyelid-elevating muscle, the levator palpebra superioris. In such a scenario, the Botox will diffuse inadvertently onto the levator muscle and cause an eyelid droop. You may have an increased risk of eye-LID drooping if you have a weakened upper eyelid muscle for neurological reasons, or a deeply set eye-BROW that would be more prone to drooping (as discussed above) and result in skin gathering over the eyelid making the eyelid appear like it was drooping. A droopy eye-LID due to Botox can be treated with Apraclonidine eye-drops which can provide a small (2mm) improvement -- Apraclonidine 0.5, 1-2 drops, 3 times per day. Make sure you put in one drop at a time, tilt your head back, and close your eyes to make sure none of the eye-drop leaks out. Be sure your prescribing physician discusses all the potential side-effects of the drops, such as "adrenaline-like" symptoms like anxiety or heart pounding; you may also experience eye irritation, eye dryness, and eye pain, amongst other symptoms. If these symptoms occur, you will likely need to take some lubricating eye drops, lower the dose, switch the eye-drops, or stop the drops altogether...
My recommendations are to seek the services of an experienced physician injector.
I think the key with Botox lies in truly understanding the anatomy of the injected area, and more importantly the variability in the anatomy between patients -- for brows, the forehead, and anywhere else you plan on receiving a Botox injection. This includes having a firm understanding of the origin, insertion, and action of each muscle that will be injected, the thickness of each muscle targeted, and the patient variability therein. As an aesthetic-trained plastic surgeon, I am intrinsically biased since I operate in the area for browlifts and facelifts, and have a unique perspective to the muscle anatomy since I commonly dissect under the skin and see the actual muscles themselves. For me, this helps guide where to inject and where not to. However, with that said, I know many Dermatologists who know the anatomy well despite not operating in that area, and get great results.
Drooping Eyelids from Crow's Feet Botox?
Generally eyelid droop comes from injections into the forehead above the brow. That's not to say it's impossible for what you are describing to have happen, but it would be very unusual.
It would be more common to have a problem with saggy under eyes when injecting the crow's feet poorly, so the risk is more below the eye than above it with this type of injection.
