Dr. Ted Leem answered:

What is the likelihood of a repeat pleomorphic adenoma causing damage to the mandibular nerve when the tumor is located low internally in the right neck/jaw and close to the jugular . The child had her first removed in 2009 when she was 9, she is no

Location

Cancer
It depends on the location. If it is near the mandibular nerve and there was previous surgery at that site, the risk is higher.

Dr. Aileen Shieu answered:

Can nerve damage heal?

Yes

Nerve_injury
If the damage does not cause the nerve to be completely cut, then healing can occur. If a nerve has been cut, it will need to be reconnected in order to grow. Nerve grows about 1 mm/day, so depending on where the injury is, it may take over a year for recovery. It is difficult after a nerve is cut to get 100% recovery, but some return of sensation can be expected after repair.

optic nerve damage in the eye?

Optic nerves

Nerve_injury
A thorough exam can help determine the extent of the damage in many cases along with visual field and OCT testing. A neuroophthalmic exam may be required in addition to an MRI or CT scan in some cases.

optic nerve damage reversible?

Depends

Central_nervous_system
on time, severity, etc. specifically depends if the neurons have died (not recoverable at this time since an extension of the central nervous system) or are just in "distress" and could recover when the inflammation or inciting factor is resolved. typically, not reversible to normal.

Dr. Barry Press answered:

Can nerve damage repair itself?

Sometimes

Carpal_tunnel_syndrome
A broad question, because there are many ways a nerve can be damaged: compression (carpal tunnel), crush, cut, etc. A "bruised" nerve can heal itself; it grows back at about 1 inch/month. If the nerve is divided, it may occasionally heal, but more often needs surgical repair--and this doesn't always result in return of function.

Does a m r I show nerve damage?

not really

Magnetic_resonance_imaging
An EMG is the best test for nerve damage. The MRI can show evidence of compression or damage but cannot quantitate it or really confirm its extent. in most cases.

can nerve damage reverse itself?

Variable

Nerve_injury
Generically, if only the coverings of a nerve are involved (myelin), and healing begins, it will take about 4 weeks. If the central portion of the nerve fibre is involved (axon), recovery is the speed of finger nail growth (.1 mm daily). Depends on location, causation, and whether successful treatment is available.
