Electroneuronography in prognosis of intratemporal facial palsy, as compared to measurements of rheobase and chronaxy.
Electroneuronography is compared to indicrect chronaximetry in the prognosis of intratemporal facial palsies. In 86 patients, the two methods were found to be congruent and in a number of cases complementary in determining impending degeneration. Both techniques are described and their results evaluated statistically. Our observations indicate that electroneuronography allows to some extent a quantitative evaluation by means of numeric parameters whereas the results of chronaximetry only give a qualitative account of nerve degeneration depending largely on the examiner's experience. Both methods, however, have a certain margin of failure and for more accurate diagnosis and prognosis simultaneous use of both methods is advocated.
