The Clinical Findings in 24 Cases of Orbiital Blow-out Fracture

The materials such as supramid, silastic, silicone and bone graft has been used to repair the orbital blow-out fracture, recently Lyodura(R) has been used. In this report, we analysed the clinical aspects of 24 patients and the usefulness of Lyodura(R) through the operative data in treatment of orbital blow-out fracture was evaluated. We also observed the course of improvement of the diplopia and enophthalmos and evaluated the difference between surgically and nonsurgically treated cases. We evaluated the results through the clinical as peets, radiologic examination and repeated diplopia test after Injury. We divided 24 patients into two groups; one group was treated by surgery (17 patients, 71%), the other group was treated conservatively (7 patients, 29%). The materials that were used to repair the fractured site were Lyodura(R) (15 cases) and resin (2 cases). In all operated cases, there were no significant complications except one case which was reentrapped by accidental pressure to the eye. The subjective diplopia in central field 30 degrees was disappeared within three months in all cases of surgically treated. In conclu sion, it is considered that Lyodura(R) is useful for repairing of blow-out fracture site and we should have to pay more attention to the surgical indication.

The Use of a Preserved Dural(LYODURA(R)) in the Congenital Ptosis Surgery

LYODURA(R) is commercial name of a cleaned, desantigenized, desenzymatised, rendered free of pyogenics, sterilized by gamma rays, and lyophilized dura. Frontalis suspension with LYODURA(R) was performed to a total of 16 patients(21 lids) of congenital ptosis with levator muscle function of 3mm or less in the ptbtic lid. The follow-up period ranged from 2 to 39 weeks with a mean of 19.6 weeks. Postoperative lid levels were judged good, fair, and poor. Good results occurred in 12 of 21 procedures(57.1 %) and fair results in 6 of 21 prqcedures(28.6%). The summation of these two indicates an overall satisfactory result of 18 of 21 cases(85.7%).
