title: Electroneuronography in prognosis of intratemporal facial palsy, as compared to measurements of rheobase and chronaxy.
abstract: 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.
