Numbness After Scalp Cyst Removal

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!

Cysts can be deep and at the upper forehead to the front of the scalp, nerve endings become superficial. Removing the skin growth must involve cutting through the skin and the nerve endings must regenerate. They heal slowly and sometimes not for months or longer. There may be very slow recovery with tingling or crawling or jabbing sensations as it heals. Usually it gradually returns to normal or close to normal over weeks to months.

Loss of sensation after removal of a large deep lesion is not uncommon. Sometimes it takes months for feeling to return. Much less often it can be permanent. You have to give it time. 

Numbness can  take weeks to months to resolve post any excision.  There rare cases where a numb area may persist permanently, but it is certainly too soon to tell for you.  Most likely sensation will slowly return over the next few weeks.  If you have any muscle weakness in the neck or shoulder, be sure to tell your surgeon.

You will likely be going back in for suture removal, so mention your concerns at that time to the medical staff.
