Sažetak

The purpose of the study was to find differences in the parameters of the response
to the blink reflex (BR) between patients with idiopathic trigeminal neuralgia (TN) and health volunteers.
A prospective cohort study was conducted over 2 years. The TN-subgroup included 15 patients
(mean age / SD 62.3 ± 10.7 years). Pain-free and healthy volunteers as a HV-subgroup (mean age
/ SD: 30.8 ± 8.1 years) were recruited from asymptomatic students of dental medicine. Diagnostic
parameters were determined by measuring latency to the onset of the BR components from electric
stimulation. The following branches of the trigeminal nerve were affected: maxillary branch only
(26.7%), mandibular branch only (20%), combined: ophthalmic branch with maxillary branch (6.7 %),
and ophthalmic branch with mandibular branch (6.7%) respectively, combined maxillary and mandibular
branch (26.7%) and affected all three branches (13.4%). The latencies of the BR, left and right
side together, between subgroups were significantly higher for values R1 (homolateral early response),
R2 (homolateral late response), R2c latency (contralaterally expressed response) in the TN-subgroup
(p < 0.05). On the basis of the presence of R1c and R3 latencies and upon considering the abnormal
findings of the BR, no statistically significant differences were found between the examined subgroups
(p > 0.05). Blink-reflex parameters (R1, R2 and R2c) were significantly abnormal comparing TN-patients
with healthy volunteers. The R3 component of the BR was related to noxious stimuli, likewise
by innocuous stimuli.
