Purpose The main aim of our study was to assess and evaluate the efficacy, long standing outcome and infection of porous polyethylene implants in treatment of orbital floor fractures. Patient and methods Twelve patients with fractures of orbital floor were included in the study. The cause of fracture was road traffic accident, self fall and cow hit respectively. They also complained of enophthalmos (n = 9), diplopia (n = 3), restricted eye movement (n = 2), impairment of infraorbital nerve (n = 3) and dystopia (n = 6). All the fractures were reconstructed with thin porous polyethylene sheets. Results No implants were extruded and there were no signs of inflammatory reactions against porous polyethylene implant. In all nine patients with pre-op enophthalmos it was corrected post-operatively with p value = 0.000 and was statistically significant; diplopia in one patient was corrected; persistence of double vision was noted in two patients. Restricted eye movement was corrected in all patients, dystopia was corrected in four patients and in two patients have persisting dystopia. Paresthesia persisted in all three patients. Conclusion Our experience was that reconstruction of orbital floor fracture using porous polyethylene implant is reliable, safe and effective and may be used for reconstruction of the orbital floor fracture with no donor site morbidity.

“…There are many studies showing the superiority of porous polyethylene over other graft materials. [34,35,41] Ng et al [13] performed a study on 30 orbital floor fracture cases treated by porous polyethylene, and none of the patients exhibited a need for removal of the implant within a follow-up period of 9 months. They described the porous polyethylene layer as a strong and easily malleable material preventing donor-site morbidity.…”

AMAÇİzole orbita taban kırıklarının cerrahi endikasyonu, zamanlaması, kullanılacak rekonstrüksiyon materyali hakkında halen görüş birliği yoktur. GEREÇ VE YÖNTEM2002-2010 yılları arasında izole orbita taban kırığı tanısı alarak ameliyat edilen hastalar (41 erkek, 13 kadın) geriye dönük olarak değerlendirildi. BULGULARİzole orbita taban kırığı tanısı alan 54 hastadan, ameliyat edilen 49 hastanın cerrahi endikasyonuna bakıldığında, %20,4'ünde göz hareketlerinde kısıtlılık ve belirgin enoftalmi, %79,6'sında koronal planda çekilen bilgisayarlı tomografi görüntülerinin etkili olduğu görüldü. Hastaların %36,7'si ilk 16 saat içinde %10,2'si en geç 72-96 saat için-de ameliyat edildi. Orbita taban onarımı için ultra ince poröz polyetilen kullanıldı. Bu çalışma nedeniyle kendilerine ulaşılan 12 hastanın enoftalmi-egzoftalmi açısından normal sınırlarda olduğu, hiçbir hastada ektropiyon ya da skleral show bulgusu olmadığı, hastaların skara bağlı herhangi bir şikayetlerinin olmadığı görüldü. SONUÇTedavi edilmediğinde enoftalmi ve çift görme ile sonuç-lanabilecek olan orbita taban kırığında, iyi prognoz doğru cerrahi endikasyon, erken cerrahi girişim ve uygun materyal ile onarıma bağlı olduğunu düşünmekteyiz.Anahtar Sözcükler: Bilgisayarlı tomografi; orbita kırıkları; orbita implantları; X-ışınları.

337Biomateriais para reconstrução da órbita Biomateriais para reconstrução da órbita: revisão da literatura Biomaterials for orbital reconstruction: literature review RESUMO O tratamento de lesões traumáticas da órbita permanece um desafio para o cirurgião maxilofacial. Quando a correção cirúrgica não é realizada ou é feita de maneira inadequada, pode ocorrer enoftalmia, diplopia, distopia ocular, restrição da movimentação ocular e disfunção do nervo infraorbital. A importância da cirurgia consiste em liberar o tecido orbitário herniado pelo foco de fratura, restaurar a arquitetura normal da órbita, objetivando um resultado estético e funcional adequado. Nas últimas décadas, vários avanços ocorreram no tratamento cirúrgico destas fraturas, bem como nos métodos diagnósticos. Com o desenvolvimento de tomografias computadorizadas de múltiplos detectores, tornou-se possível a análise tridimensional da órbita, assim como sua avaliação volumétrica, o que revolucionou o manejo cirúrgico destas fraturas. Outro fator com impacto direto nas reconstruções das órbitas é a disponibilidade de diversos biomateriais, para restauração das paredes orbitárias. Assim, o objetivo desse artigo é revisar os materiais disponíveis para reconstrução nos casos de fraturas do assoalho da órbita, comparar suas aplicabilidades práticas e destacar aqueles mais utilizados no Serviço de Cirurgia Plástica do Hospital de Clínicas da Unicamp, nos últimos anos. Dentre os materiais de escolha, em nosso Serviço, destacamos o osso autó-geno de calota craniana, a cartilagem de concha auricular, a tela de titânio e o polietileno poroso de alta densidade. Cada biomaterial apresenta indicações específicas, de acordo com as características da fratura orbitária, sendo considerados, para a escolha do material, os resultados a longo prazo e a experiência do cirurgião.Descritores: Órbita/lesões.

When surgical correction is not performed or is performed incorrectly, may occur enophthalmos, diplopia, ocular dystopia, restriction of ocular movements and dysfunction of the infraorbital nerve. The importance of surgery is to release the herniated orbital tissue at the fracture site, restoring the normal architecture of the orbit, aiming at an adequate functional and aesthetic results. In recent decades, many advances have occurred in the surgical treatment of these fractures, as well as in diagnostic methods. With the development of multislice CT, it became possible to analyze three-dimensional orbit, as well as its volumetric evaluation, which revolutionized the surgical management of these fractures. Another factor with direct impact on the reconstruction of the orbits, is the availability of various biomaterials for the restoration of the orbital walls. The objective of this paper is to review the materials available for reconstruction in cases of fractures of the orbital floor, its applicabil...

Long-Term Outcomes of Ultra-Thin Porous Polyethylene Implants used for Reconstruction of Orbital Floor Defects

Abstract: We recommend the use of ultra-thin porous polyethylene implants in the reconstruction of the orbital floor defects in facial trauma patients. The implants are durable in the long-term and mimic the anatomy of the thin orbital floor and avoid the morbidity of autogenous bone grafts.
