“…A potential problem associated with TSEFs is stimulus artifacts and direct or reflex muscle activities, which heavily contaminate MEG and EEG recordings (Arcuri et al, 2006). The early component N15m (N, negative current; 15, intermediate value of peak latency in ms; and m, magnetic counterpart of electrical response), reported previously (Nagamatsu et al, 2001), was not always detectable in the current study, probably because of its low amplitude and the influence of artifacts.…”

“…One promising method is to block IAN conduction using a local anesthetic to temporally mimic trigeminal nerve dysfunction, and to monitor TSEF changes. Two EEG studies have reported a flattening of TSEP peaks after IAN anesthesia (Narita et al, 1997;Arcuri et al, 2006). However, the spatial resolution of EEG is insufficient for localizing the neural substrate for the change.…”

For objective neurophysiological evaluation of the function of the trigeminal system, magnetoencephalography- based TSEF (trigeminal somatosensory-evoked field) assessment would be valuable in providing spatial and temporal profiles of cortical responses. However, this necessitates knowledge of how TSEF varies with trigeminal nerve dysfunctions. We introduced a conduction block of the trigeminal nerve using local anesthesia (lidocaine) to temporally mimic nerve dysfunctions, and monitored TSEF changes. Following an electrical stimulation of the lower lip, a magnetic response with peak latency of approximately 20 ms was identified in all participants. Dipole for the peak was estimated on the post-central gyrus in the participant's own magnetic resonance image. After normalization to Montreal Neurological Institute (MNI) space and inter-participant data integration, the summary equivalent current dipole localization among participants remained in the post-central gyrus, suggesting validity of the use of MNI space. Partial anesthesia of the lower lip led to a loss of the waveform characteristics of TSEF for electrical stimulation to the trigeminal nerve. We verified that the 20-ms latency cortical response of TSEF components localized at the primary sensory cortex can serve as a robust neurofunctional marker of experimental trigeminal nerve dysfunction.

“…La discrimination sensitive entre 2 points immobiles au niveau de la lèvre inférieure est normalement de l'ordre de 3 mm [1] comme observée dans notre cas à 6 mois postopératoires. Les PES permettent d'étudier la conduction nerveuse du NAI de façon fiable et plus précoce que l'examen clinique [10]. Leur exploration après reconstruction du NAI reste cependant originale car non décrite dans la littérature.…”

“…Leur exploration après reconstruction du NAI reste cependant originale car non décrite dans la littérature. Contrairement aux amplitudes, la modification des latences est corrélée à la récupération nerveuse [10], comme observée dans notre cas après 6 mois. L'autogreffe de NGA constitue une technique simple, fiable et efficace pour le rétablissement de la continuité du NAI après mandibulectomie interruptrice et peut être réalisée dans le même temps que la reconstruction osseuse.…”

“…These experimental conditions were based on previous studies. [7][8][9][10] The patch was applied to the canine gingivobuccal fold for 5 minutes (Figure 2). After removal of the patch, the area was dried fully with air, an electrode was immediately placed on the area, and TSEP was measured.…”

We analyzed trigeminal somatosensory evoked potentials (TSEP) to the alveolar mucosa to investigate the efficacy of an amide local anesthetic, 2% lidocaine hydrochloride with 12.5 lg/mL epinephrine (Lido treatment) as a topical anesthetic. Eighteen consenting healthy adult volunteers were enrolled. A volume of 0.06 mL of Lido, 0.06 g of 20% benzocaine, or 0.06 mL of physiological saline (control) was instilled onto a hemostatic adhesive patch, which was then applied to the alveolar mucosa at the maxillary right canine for 5 minutes. An electrical stimulus approximately 5 times that of the sensory threshold was applied using a surface stimulation electrode. The trigeminal somatosensory evoked potential was recorded immediately, 5 minutes, and 10 minutes after removal of the patch. Positive P125 and P310 peaks and negative N100 and N340 peaks were observed as a result of the electrical stimulation. A significant decrease in the percentage change in amplitude of N100-P125 was observed in the Lido treatment immediately, 5 minutes, and 10 minutes after patch removal. In the Lido treatment, trigeminal somatosensory evoked potential amplitude at N100-P125 decreased significantly, suggesting that topical anesthesia produced by an amide local anesthetic may have a topical anesthetic effect as potent as that produced by an ester local anesthetic.
