[Use of Lyodura in fractures of the orbital floor]

After a brief review of reported techniques for the reconstruction of substance losses of slight or modest proportions at the orbital floor using autogenic, homogeneous, heterogeneous and alloplastic grafts, personal experience with this type of surgery employing lyophilised human dura mater is reported. It is considered that Lyodura can be considered the material of choice by virtue of its strength, handiness and the absence of tissue reactions. 38 fractures of the orbital floor were treated from 1980 to 1986 with osteosynthesis of the border and insertion of lyophilised dura mater to make up for bone loss. In the immediate postoperative period and in later controls, there was no evidence of complications or phenomena of intolerance to the material. The patients treated were followed up a short time later. Clinical and X-ray data confirmed the validity in time of the technique and material employed long-term.
