4 months post lipo my belly button is still numb. Is this permanent?

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. 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!

It’s not unusual for patients to
have numbness following liposuction of the abdomen.This usually results from swelling and trauma
from the liposuction cannula.In
the vast majority of patients, these symptoms usually resolve
spontaneously.In most cases, swelling
has resolved in three to four weeks but occasionally may take as long as three
to four months to resolve.In most
cases, the numbness has resolved at this point as well, but in rare cases it
may last up to a year following surgery.In some cases, it may ultimately prove to be permanent.It’s
still early in the post-operative period, but if these symptoms fail to improve
consultation with a board-certified plastic surgeon would be appropriate.

Many patients experience numbness over the treatment areas. Over time the feeling will gradually return to normal. As the feeling comes back you may notice some electric tingling sensations which is quite normal and will subside. Most sensory changes go away by 6-8 weeks, but this can take over a year in some cases.

Permanent numbness after liposuction is possible but extremely rare and unlikely. Generally give this up to two years before drawing any final solutions.

There are many cases of sensory return after a year or more from its onset.  Frequently, though, the patient feels occasional tingling or "crawling" sensations as the nerve wakes up from its procedure-related sleepiness (neuropraxia).  Permanent sensation differences, both a lack of as well as hypersensitivity, are possible side effects of liposuction and are tolerated for the other benefits of the procedure. Should it occur, it is not something that would be avoidable, it is just the way the body heals.
