The outcome of nerve repair is dependent on the degree of the nerve injury and the circumstances at the site of injury. [5] Since neurapraxia is the least serious form of peripheral nerve injury, recovery and treatment are not extensive. Once the cause of neurapraxia is eliminated, recovery of the lesions in the nerve occurs within a short time ...
This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Nerve injury; Fluorescent micrographs (100x) of Wallerian degeneration in cut and crushed peripheral nerves. Left column is proximal to the injury, right is distal. A and B: 37 hours post cut. C and D: 40 hours post crush. E and F: 42 hours post cut. G and H: 44 hours post crush. Specialty: Neurology
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).

There are three main patterns of facial nerve compression. The type of injury also gives an idea about the prognosis. Neuropraxia: no wallerian degeneration and complete and rapid recovery of function. Axonotmesis: wallerian degeneration and necrosis of the distal segment (death of the part of the nerve after the compression). Recovery is not ...
