Facial electroneurography: results on normal humans.
Electroneurography (ENoG) is one of the tests recently introduced for the clinical analysis of facial paralysis. Right-left facial differences, test-retest variability and differences between the first and the last CAPs after 25 consecutive stimuli were studied in 24 normal subjects. Significant inter-subject right-left differences were not found. Intra-subject results show an average variation of 25 per cent in the amplitude between either side of the face. Test-retest variability is minimal both for the amplitude and for the latency (3.15 per cent and 1.9 per cent respectively). No differences in amplitude or in latency were found between the first and last compound action potentials gathered after 25 consecutive stimuli.
