Summary. The middle latency of the somatosensory evoked potentials
(SEPs) of the trigeminal nerve by electrical stimulation of the upper and
lower lips in 20 healthy subjects and 25 patients who had different lesions
of the trigeminal nerve and its central pathway vas studied. Changes in
peak latencie and amplitude of wave N19 are correlated with clinical findings
especially in multiple sclerosis (MS) and trigeminal neuralgia. The technique
is simple and painless. Midle latency SEPs of the trigeminal nerve could
be an appropriate method for analysis and evaluation of the function of
the trigeminal nerve and its central pathway.
Key words: Somatosensory evoked potentials, trigeminal nerve,
trigeminal neuralgia, multiple sclerosis
SOMATOSENZORNI EVOCIRANI POTENCIJALI SREDNJE
LATENCE TRIGEMINALNOG NERVA U ZDRAVIH ISPITANIKA I KLINIČKA PRIMENA
Kratak sadržaj. Somatosenzorni evocirani potencijali (SEP) srednje
latence nervusa trigeminusa električnom stimulacijom u predelu gornje i
donje usne ispitivani su kod 20 zdravih ispitanika i 25 bolesnika sa jasnim
kliničkim znacima lezije trigeminalnog sistema u perifernom i centralnom
delu. Rezultati ispitivanja su pokazali promene u latenci i amplitudi talasa
N19 i korelirani sa kliničkim nalazima različitih oboljenja, posebno kod
multiple skleroze (MS) i trigeminalne neuralgije. Tehnika je jednostavna
za upotrbu i bezbolna. Može imati praktičnu kliničku primenu kao dopunska
dijagnostička metoda za ispitivanje poremećaja funkcije trigeminalnog nerva
i centralnih puteva.
