The use of lyophilized dura in reconstruction of the orbital floor.

The results and experiences with the use of lyophilised human dura in 52 cases are reported. Experimental work carried out on rabbits demonstrate that human lyodura is replaced by a layer of connective tissue. Both, the results of animal experiments as well as those experienced in 52 clinical cases suggest that lyodura is an excellent material for the reconstruction of defects of the orbital floor.
