Abstract
The following question was investigated in experiments on the sciatic nerve of the guinea pig. Does ionizing radiation in doses used for the thorough after-treatment after excision of malignant tumors of the parotid gland seriously endanger regeneration in a reconstructed peripheral nerve – in this case the facial nerve? The clinical experience with a large number of operative reconstructions of the facial nerve in the parotid and masseteric region (Conley; Miehlke) is confirmed. Ionizing irradiation after operation, with focal doses between 4,500 and 6,000 rad in 25 days, leads to a moderate limitation of the speed of regeneration of the nerve but not to serious interference with reneurotization of the mimic muscles. This irradiation will not cause any asymmetry of mimic innervation worth mentioning.
