The neuromonitor has found widespread use in parotidectomies for the purposes of avoiding
or minimising insult to the facial nerve. However, its exact utility has been questionable, with
differing opinions regarding its most appropriate application, and with little consensus as to
the threshold of an applied amplitude, generating a CMAP, can be said to accurately predict
facial nerve dysfunction, as defined by the House-Brackmann score, one week following the
parotidectomy. It is the purpose of this paper to definitely state as to the exact use of the
neuromonitor; whether its utility is overstated or whether it may form the future of
parotidectomies. We used a dichotomous approach, comparing all literature concerning the
neuromonitor, both contemporary and historic, as well as expounding upon the
electrophysiological basis of the device in order to reach a conclusion. The purpose of the
neuromonitor encompasses the context of facial nerve preservation; it is our aim to also
discussing both patient features and surgical features as a whole that may play a role in the
development of facial nerve dysfunction. This provides us context to the overall utility of the
neuromonitor and thus would enable us to fully assess the extent to which the neuromonitor
may be utilised in preventing facial nerve dysfunction. It is thus we may further expound on
the new, novel techniques that may be used in parotid gland surgery that would enable us to
reduce facial nerve dysfunction as a main surgical complication in the management of parotid
gland tumours
