Answer

Surgical decompression of the nerve and excision of the offending lesion are indicated in cases of nerve compression due to external causes, such as those associated with intraneural or extraneural tumors or masses.

Löwenstein et al recommend early surgical treatment in cases involving intraneural ganglion cysts, in order to minimize neural invasion (which may cause irreversible axonal injury and foot drop). [62] In cases in which severe paresis and muscle atrophy are present, surgical exploration may also be warranted, especially if electrodiagnostic evidence of active motor axonal degeneration is present.
