“…Another drawback of pure PDS was that degradation may lead to an inflammatory reaction involving the surrounding periorbita [21], with possible scar formation and consecutive functional motility disturbances of the globe, leading to recurrence of diplopia in 3 of 31 patients 6 months after a diplopia-free period [17]. Silicone, hydroxylapatite, poly-L-lactide, Teflon and Medpor are other alloplastic materials that are reported to have late complications such as infection, diplopia and implant migration associated with them [16,[29][30][31][32][33][34][35]. Cortical bone grafts are advised in larger defects of the orbital floor and the medial wall [10,27].…”

“…Contrary to the studies recommending waiting for a certain period of time, there are surgeons who advocate early surgery because of the more flexible nature of the fracture line and the easy-to-release character of the herniating tissue as well as availability of a less traumatic intervention, with low diplopia and enophthalmos incidences during the early period. [9][10][11][12][13][14] In our case series, except for the 6 patients showing an indication for emergency surgery, patients exhibiting an indication for surgery were operated on within a time range of 6 -92 hours (Fig. 2).…”

“…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.

“…Regarding morbidity, complications at donor sites of autographic materials are few, most commonly scars and rarely cutaneous nerve injury. On the other hand, synthetic materials have demonstrated less donor site morbidity and facility in handling: polyethylene, hydroxyapatite, and silicon plates have been adapted for orbital floor reconstruction [8,9]. However; these unabsorbable materials have higher potential for infection and foreign body reaction.…”

Objective This study evaluated and compared the efficacy of mandible and iliac bone as autogenous bone graft for correction of orbital floor fractures. Patients and Methods Twenty patients who suffered orbital floor fractures took part in the study. The subjects enrolled in the study sustained both isolated orbital floor fracture and orbital floor fracture associated with fracture of zygomatico-maxillary complex. Each inferior orbital wall was reconstructed using either a mandible bone graft or an iliac graft. Mandibular symphysis was opted as a donor site for graft harvest from mandible and anterior iliac crest for the iliac group. CT scans were taken before the operation. Inclusion criteria consisted of at least 2 months postsurgical follow-up, pre-and post-surgical photographic documentation, and complete medical records regarding inpatient and outpatient data. To describe the distribution of complications and facilitate statistical analysis, we categorized our findings into diplopia, enophthalmos, and restriction of ocular movements before and after treatment.We also considered the time required for the harvest of the grafts and the donor site complications. A comparative study was carried out using Chi square test and student t test. We considered P value \0.05 to be statistically significant. Results Ten iliac crest grafts and ten mandible bone grafts were placed. The mean age of the patients was 33.1 years. 80 % of the patients were males. The most common complication of orbital floor fracture was diplopia, followed by enophthalmos and restriction of ocular movements. The post operative results were compared after 2 months of the surgery. In iliac crest group, diplopia got corrected in six out of seven patients (85 %), enophthalmos in four out of five patients (80 %) and restricted ocular movement showed 100 % correction. While in mandible group, diplopia and ocular movement showed 100 % correction and enophthalmos got corrected in five out of six patients (83 %). No statistically significant differences were found between the two groups on comparing these variables. On the other hand the mean time required for the harvest of iliac graft and mandible graft was 30.2 ± 3.52 min and 16.8 ± 1.75 min respectively. The difference was statistically significant. Conclusion There is no difference in the ability of mandible and anterior iliac crest bone grafts to correct posttraumatic diplopia, enophthalmos and restricted ocular movements. But the time and ease of harvest of the graft from mandible was comparatively less and easy especially when the treating doctor was an oral and maxillofacial surgeon. Secondly the post-operative morbidity was low and the quality and contour of the bone graft was very adaptable for the reconstruction of the orbital floor.
