[Bulbus motility in early and late surgery of orbital floor fractures (author's transl)].

Among 638 patients with fractures of the middle third of the facial skeleton 139 were found to have clinically relevant fractures of the orbital floor. 74 of them were followed up ophthalmologically and by x-ray examination. In 49 patients the results of the operative treatment were judged from a detailed questionnaire. Operation within 2 weeks after the accident yielded better results than later operation. Persisting motility disturbances concerned mainly the upper field of gaze.
