As an alternative to those patients who cannot be performed an awake spinal cord stimulation (SCS) or had been percutaneously implanted with poor pain relief outcomes, neurophysiological monitoring through transcranial motor evoked potentials (MEPs), somatosensory-evoked potentials (SSEPs) and free-run electromyography (EMG) under general anesthesia allows the correct placement of surgical leads and provide objective responses.
We read with interest the report by Zoia, and we would like to widen the picture by sharing our experience in Madrid’s COVID-19 reference center, one of the hardest hit areas in Europe. As neurosurgeons, we never would have imagined being in the eye of the storm. We hope our humble experience can be helpful to colleagues in other countries.

Abstract: Objectives To analyze the outcome of facial nerve (FN) reconstruction, the impact of technical variations in different conditions and locations, and the importance of additional techniques in case of suboptimal results.
Patients Between 2001 and 2017, reconstruction of the FN was performed on 36 patients with varying underlying diseases. Interventions FN repair was performed by direct coaptation (n = 3) or graft interposition (n = 33). Microsurgical sutures were used in 17 patients (47%) and fibrin glue was used in all cases. Additional reinnervation techniques (hypoglossal–facial or masseter–facial transfers) were performed in five patients with poor results after initial reconstruction.
