Can Dysport Result in Permanent Damage to Orbital Septum?

Thank you for your question. Be certain to be under the supervision of a board certified dermatologist or plastic surgeon with expertise in injectables for the safest and most effective treatments. It is best to obtain an evaluation to advise you the right treatment. If it is a fat pad, surgical removal is the recommended treatment. I hope this helps.

Injection too medially into the orbicularis oculi can cause a puffy appearance.  I recommend following up with your injector and reviewing photos to determine if it was present before and what your options are for correction.

I have never seen this be permanent.  However, I have seen a few patients who were convinced that botulinum toxin cause fat herniation.  When the before treatment photos were used, it turned out it each case that the herniation was present before hand.  If you injector did not get before photos-shame on them.

In addition to what has already been proposed, one common problem following the injection of botulinum toxin can be the formation of festoons or fluid pockets underneath the eyelid. The normal muscle tension of the orbicularis muscle may hide this tendency under normal circumstances. However with the loss of tone, any skin or muscle laxity is likely to reveal itself and may result in the formation of festoons. On a positive note, your condition should self-resolve as the toxin wears off. Best wishes

Dysport will not cause any herniation in your fat pad.  You should find that your dysport is functional for about 16 to 20 weeks in general.  At this point, I believe you have no further action of the injected dysport and likely need a consultation with a board certified physician.  Although off label, I have had tremendous success injecting around the periorbit and have been doing so for years.
