These can include: further limiting target reinnervation and functional recovery. A sural nerve biopsy may be useful to enable the clinician to diagnose the etiology and underlying pathology of patients presenting with symptoms of a peripheral neuropathy, when no clear underlying cause has been determined with conventional assessment such as electrophysiology or quantitative sensory testing. Nerve Biopsy Findings Nerve Biopsy Teased Fiber: Segmental demyelination Onion Bulb formation Inflammation: Epineurial & endoneurial Nerve biopsy is not essential for the diagnosis of CIDP; however, if there remains a question of the diagnosis, nerve biopsy remains a useful diagnostic tool.
The conclusions were that sural nerve biopsy is associated with prolonged sensory symptoms and sensory loss, that recovery occurs in all patients irrespective of diagnosis, and that residual sensory loss in diabetic and nondiabetic patients are comparable.
