Objective To evaluate the clinical result of using osseointegratedimplants to retain removable orbital prostheses in repairing orbital defects. Methods Two patients with orbital defects caused by orbitaltumor were treated. Each of them got 4 implants. After average 6 months, we performed the secondary operation. After 7 weeks, we took impressions to make the implant-retained prostheses. The magnetic attachment was adopted. The prostheses were made of polysiloxane material(Factor II,Lakeside,Ariz). Results Both of the patients got the successful facial prostheses and were followed up 2 and 8 years respectively. All the implants were integrated well. There were no apparent inflammatory reactions in the soft tissue around percutaneous implants. The patients were satisfied with the facial appearance. Conclusion Implant-retained orbital prostheses are safe and effective in repairing orbital defects.
Two cases of sever defect of the orbital region were re-paired by vascularized forearm skin flap, and the cycbrowwere reconstureted by the island scalp flap,and the cycbrowwere reconstructecd by the island sealp flap with the superfi-cial temporal vessel as the pedielc. The operation was success-ful,and a good appearance was obtained. The author indicat-ed that the thorough debridement,patent drainage,and goodinterial supporting tissue were the key points in achieving op-eration success.
Objective To observe the clinical manifestations and the effect factors of thyroid-associated ophthalmopath (TAO) with optic neuropathy. Methods The clinical data of 62 cases (120 eyes) of TAO with optic neuropathy diagnosed in 1994-2001 were retrospectively analyzed. Results The incidence of TAO with optic neuropathy was 18.3% in all the simultaneous TAO inpatients, and was more frequently found in the male than in the female ones. The incidence of TAO with optic neuropathy was correlated with orbitono-increase, ocular myopathy, hypertension, hyperlipemia, diabetes, and cardiopathy (P＜0.0000), but not with exophthalmos, intraocular pressure, and the disease course of TAO (Pgt;0.05). In 62 patients with the methylprednisolone pulse therapy, the visual acuity improved in 33 (29.0%), improved while the treatment but decreased after stop treating in 29 (24.2%), and no changes in 58 (46.8%). In 63 eyes undergone orbital decompression with methylprednisolone pulse therapy, 59 (93.7%) had better visual acuity. Conclusion The incidence of TAO with optic neuropathy was correlated with orbitono-increase, ocular myopathy, hypertension, hyperlipemia, diabetes, and cardiopathy. Met hylprednisolone pulse therapy and orbital decompression are the effective measures for TAO with optic neuropathy. (Chin J Ocul Fundus Dis，2004，20：142-144)
Objective To provide references for clinical management of patients with orbital blow-out fractures. Methods Evidence was retrieved from The Cochrane Library online (Issue 1, 2009), ACP online, NGC (1998 to March 2009), PubMed (January 1950 to February 2009), and CBM (1994 to February 2009). The collected evidence was then graded. Results After preliminary research, we identified 12 relevant articles: either retrospective studies or comments from specialists. They studied orbital soft tissue entrapment, diplopia, enophthalmos, or severe oculocardiac reflex in the surgical indications of orbital blow-out fractures. Most of the literature suggested less than five days after the injury incursion for children and less than two weeks for adults was the optimal time to undergo operation. However, advanced surgery was still a good option for the patients that could not undergo early surgery. With regard to the use of poly-pdioxanon- foil and titanium-dynamic mesh, two randomized controlled trials suggested that the former was superior to the latter. Conclusion The application of this surgery should be cautious because of low levels of evidence. Individual therapies should be used after close consideration of clinical characteristics.
