How long will chin and lip numbness last after chin implant surgery?

Hello! Thank you for your question! Numbness after any surgical
procedure is expected for several weeks to months following. As the
nerves to the area are traumatized and will then experience a temporary
neuropraxia, a transient loss of nerve conduction. This usually
resolves over the next 6-12 weeks, but depending on the procedure
performed, sometimes much longer. Typically this should resolve by 1
year. As it goes past this date, the likelihood of the sensation
returning is small. However, it can take up to 2 years. If no return
from there, it is unlikely to return. It should be discussed that
persistent sensory changes may develop following any surgical
procedure.  If no resolution, the implant may need to be adjusted.The usual signs of the nerves regenerating and neuropraxia
resolving is itching, followed by a burning sensation and then
occasional sharp, shock-like pains. These will be normal to experience,
and actually a promising sign. Usually, normal sensation returns, but
is is also possible to have decreased sensation or even increased
sensation to the areas affected. Re-educating nerves postoperatively is
often helpful and will allow proper instruction for the affected
sensory nerves - methods include using different textures to the
affected areas when showering, bathing, applying lotion, etc. If
bothersome, there are some medications that may be helpful, including
Neurontin for pain for hypersensitivity. You can try various textures
such as washcloths, loofahs, cotton sheets, etc. Massaging the areas is
also beneficial for the incision to make the finest scar possible. The
last place to regain the sensation will be directly adjacent to the
incision/scar as the nerves will make its way from the periphery to this
location. If continual pain arises, evaluation is warranted. After
ruling out other causes, one rare explanation may be that a neuroma has
developed and may require surgical excision. This is very unlikely
unless a large sensory nerve has been transected inadvertently during
the procedure. Hope that this helps! Best wishes!

The numbness may be the result of the pocket dissection or an impingement of the wings of the chin implant on the mental nerve. As long as you are not having pain on the numb side, I would wait a few more months to see how much improvement has occurred. If no significant improvement occurs, the implant wings may need to be adjusted/reduced in size. 

This can take several months to resolve. Permanent numbness is possible but uncommon in the hands of an experienced chin implant surgeon. Usually, the tingling that you feel represents recovery of the nerve from being stretched. This should improve over time but if it does not, contact your surgeon. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

You should let your  sugeon know about this. If after 60 days there is no improvement, removal of the implant might be considered. Your sugeon would be the best person to judge. Good luck,

Numbness of the lip after chin implant can last for 12 weeks.Your doctor will be able to answer better since he/she did the surgery, and knows how far the implant was from the mental nerve.If this numbness last beyond 12 weeks then a full re-evaluation is neededSamir Shureih MD.

The numbness usually resolves slowly over about 4 months give or take a few weeks. If it persists much longer than that then it may not come back, but from your description of the feeling it sounds like a very temporary problem.
