[Neurologic examinations for facial nerve damage in surgically treated mandibular collum fractures].

Transcranial magnetic stimulation is a new method for objective evaluation of the facial nerve without constraints for the patient. By the first time, especially cortical lesions can be detected objectively. Using this method, a permanent disturbance of the ramus marginalis mandibularis after operative treatment of fractures of the mandibular condyle could be certainly excluded. Therefore, because of the clear presentation and the possibility of enlargement, the deep submandibular approach, using a correct operative technique, can be strictly recommended.
