Numb Thigh After Tummy Tuck Surgery

Nerves are tricky things. The area you are describing is supplied by the lateral femoral cutaneous nerve. Several things could be occurring - irritation, entrapment, injury, neuropraxia, etc. Most of the time nerve issues resolve with time - months and years. Occasionally, there is an intervention that can release the nerve from entrapment. You should discuss these issues with your doctor.

Thank you for your question regarding numbness in your thigh after tummy tuck surgery. While numbness in the abdominal area is common after a tummy tuck, experiencing it in your outer thigh can occur due to the involvement of the lateral femoral cutaneous nerve, which runs through the abdominal and pelvic region. This nerve can sometimes be irritated or compressed during surgery, leading to numbness in the thigh.

In most cases, this numbness will improve over time as the nerve regenerates, although the timeline varies from person to person. Full nerve recovery can take up to a year or more. It's also important to avoid any activities that may further irritate the nerve, such as wearing tight clothing or overexerting the area.

To promote nerve regeneration, gentle massage, physical therapy, and taking care not to put excess pressure on the affected area can be helpful. While nerve recovery is often gradual, the numbness should decrease with time, but if you notice any worsening or persistent discomfort, it’s always a good idea to consult your plastic surgeon for further evaluation.

Sincerely,
Dr. Katzen

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.  You likely have some neuropraxia to the lateral femoral cutaneous nerve of your thigh.  While this is most likely, the nerve could have been cut or entrapped.  Be patient - if worsens or does not resolve, surgical intervention may be entertained - regardless, follow up closely with your surgeon.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!

As Dr. Shafer has described there are several possible explanations for the reported numbness. The lateral femoral cutaneous nerve lies close to the incision particularly if a low lying incision is used. Nerves can be bruised, injured, entrapped, transected, etc. In many instances this will resolve but it may take time. Occasionally the recovery of a nerve can be traced using the "Tinel's sign" which is tingling elicited by tapping over the regenerating end of the nerve.

Thank you for your post. In a tummy tuck or abdominoplasty surgery, the tissue above the abdominal muscles is lifted off of the muscles from the lower scar to the ribs in a full tummy tuck and to the umbilicus in a mini tummy tuck. The superficial nerves that travel through the muscle to the skin are cut in order to do this. This is what causes the numbness afterward. The numbness usually extends in the entire area that was lifted up. On occasion, a superficial nerve to the thigh could be pulled causing numbness in this area as well. Swelling happens after surgery and also tends to be in the entire area that has been lifted up and any area that has received liposuction. Both numbness and swelling may take months to years to go away, and the last place for both to go away is the area right above the incision centrally, and sometimes right below the belly button. It may take up to 2 years to get to baseline sensation. sometimes, certain areas never feel totally normal, especially the area right above the incision centrally. If tingling or itchiness develop, that is a sign that the nerves are growing back. This is normally well tolerated, but occasionally, a nerve type pain medication is needed such as neurontin.
