Armando Tellez et al. BTS 2016;1:288-295 Nerve Atrophy and Neuromatous Regeneration To the left, representative histological images of nerve atrophy. Nerves distal to the location of delivery of the radiofrequency therapy typically show histological evidence of atrophy (asterisks and solid arrows). To the right, representative image of neuromatous regeneration easily identifiable with conventional stains (hematoxylin and eosin [H&E]) as increased fibrous tissue response (blue dotted line) and nerve “sprouts” (solid arrows) disrupting what was the original anatomy of the nerve (black dotted line).
