Had my 3d Kybella treatment on Friday. Woke up on Monday with lower lip dropping on the left side.

Question

Asymmetry is noticeable when I smile with lips open, mouth wide open, and lip retraction. No asymmetry when I smile with lip closed or pucker lips. There is a new feeling of numbness radiating toward my cheek and ear areas. Did my treatment with a board-certified dermatologist who is highly respected in my community. She followed the grid and everything went smoothly. I called her and she said if doesn't resolve in 2 weeks to see her. I understand its a nerve damage. Is it permanent?

Hardik Soni, MD · Answer

It is one of the risks after the Kybella treatment that occurs with small percentage of patients. It should resolve itself. It may not go away within the 2-week time frame, but it will within 4 weeks. Anyhow, you should have a follow up with your provider after 2 weeks. Good luck!

Thank you for
your question kat39. I am sorry to hear about your situation. Kybella
is the first and, thus far, only non-surgical injectable treatment for the
double chin. The pivotal studies demonstrated that a marginal mandibular nerve injury may occur less than 5 % of the time leading to a temporary asymmetric smile. The median duration is about six weeks; it is not permanent. Please
follow up with your doctor for specific recommendations. Good luck!

It sounds like your mandibular nerve was effected which should go away in a few weeks.  It sounds like it should resolve in a few weeks.  Best, Dr. Green

You have one of the rare, but temporary side effects from the inflammation caused by the Kybella injections. It will resolve but could takes weeks to months. There are strategic injections of Botox or Dysport that can be done to make the asymmetry less noticeable while it is resolving, talk to your physician about this at the follow up.

I am so sorry that you are experiencing this, but it should be temporary. That's the good news. The bad news is that it may take a few weeks to resolve. Hang in there and yes, if things don't improve in 2 weeks, see your surgeon.Kindly,Kouros Azar

Paul Pietro, MD · Answer

Hello kat39,Thank you for sharing your question and concern. Temporary paralysis of the Marginal Mandibular Nerve post Kybella treatment is a recognized complication of the Kybella treatments. It was not shown to be permanent in any of the trials leading up to its FDA approval with a median duration of 44 days until spontaneous resolution. Follow up with your physician as she has already you scheduled for knowing this will resolve itself.

Katherine Dee, MD · Answer

Hang in there. In the original Kybella study, 4% of participants had a similar nerve injury and all were temporary. This can happen despite the best techniques. It should resolve over the next few weeks. I wish you the best -- and I hope meanwhile the Kybella is working on the fat!

Shaun Patel, MD · Answer

Sorry to hear about your experience. An asymmetric smile is probably the result of the Kybella diffusing to the nearby marginal mandibular nerve. This causes an injury to the nerve which is temporary in almost every case. Your smile should return to normal on its own over next month if not sooner. Botox can be injected into the lip depressor muscles on the opposite side of the injury to help make the smile more symmetric although I suggest that you just wait for the injury to resolve on its own.
