A Illustration of HL and demyelination of Schwann cells (SCs). Among many different etiologies of sensorineural HL (SNHL), the extensive loss of the myelinated axonal processes in the auditory nerve may be followed by alteration or degeneration of hair cells (HCs) and spiral ganglion neurons (SGNs). The resulting degenerative process reduces the neuronal capability in initiating and propagating action potentials in response to electrical stimuli, leading to nerve conduction vulnerability. B Anatomical illustration of the internal ear structures affected by VS (also called acoustic neurinoma).
