Neuronography in Facial Palsy-Results of Long-term Observations
Three hundred ad twenty-six patients with idiopathic (Bell’s) palsy and 21 patients with traumatic facial palsy were seen by the author between 1972 and 1983. The course of the palsy was followed by neuronography and rheobase-chronaxy measurements. Nineteen of 27 patients with sigs of denervation at the time of disease were reevaluated clinically between 1989 and 1990; 8 were lost to control; 5/15 patients with idiopathic facial palsy had tympanomastoidal decompressive surgery and steroids; 10/15 had only steroid therapy. In both groups distribution of final results within the House grading system were comparable with each other and in general surprisingly satisfactory. Similar results were found in trauma cases, where 5/21 fulfilled denervation standards, and 4/21 were seen and tested. Of these 4, 3 had an indication of severe nerve damage, confirmed by surgery in 2 (subtemporal); in a further case there was only compression by bone particles. One was not operated on.
