A biopsy of the donor facial nerve is obtained for axonal count, and 2-3 epineurial 9-0 nylon sutures are used to complete the neurorrhaphy. in the area of skin supplied by the nerve that is biopsied. Skin biopsy is a minimally invasive technique with the advantage, compared to sural nerve biopsy, of being suitable to be applied DESIGN/METHODS: A retrospective analysis of sural nerve biopsy reports done between period of January 2000 and March 2010 were accessed at Neuropathology Department Frenchay Hospital Bristol.

A small limbal biopsy was obtained from the unaffected eye. In the last three decades the study of cutaneous innervation through 3 mm-punch-biopsy has provided an important contribution to the knowledge of small fiber somatic and autonomic neuropathies but also of large fiber neuropathies. (a) A longitudinal incision has been made posterior to the lateral malleolus. A needle biopsy of the sural nerve resulted in the formation of a hematoma. I think that would require a sural nerve biopsy.
I only had a skin biopsy to determine the severity of SFN, small fiber neuropathy. 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.
