[The therapy of zygomatic fractures. Clinical and experimental studies]

The analysis of 120 patients with zygoma fractures showed disturbances of sensibility in the field of the N. infraorbitalis in 84% and pathological statements of eyes in 20%. The re-examinations of 76 of these patients 0.5-4.5 years postoperative showed that more than the half of these patients, who were treated by only the bone-retractor have a redislocation of the zygoma, and 49% of all cases have permanent damages of the N. infraorbitalis. The reason for the damage of the nerve is not only the compression of the nerve for a short time by the dislocated zygoma but also regular present additional splits of the orbital floor, along the Canalis infraorbitalis. This statement is demonstrated in the present work by experimental examination.
