This study provides the absolute limit of safe internal orbital dissection in respect to the local population. Despite males having larger orbits than females, it is clinically negligible.
This study was aimed to produce a clinically applicable model of composite bone graft capable of treating CSBDs in the mandible with a single surgical procedure. Twelve male white New Zealand rabbits were divided into two groups: control, n=4, consisting of A (untreated) and B (BCP/FS); experimental, n=8, named C (BCP/FS) and D (BCP/FS+VEGF). A circular CSBD (8-mm Ø) was created on both sides of the mandible. Four rabbits were prepared for BCP/FS on one side of the mandible, leaving CSBD on the other side of the mandible untreated. Another set of eight rabbits with CSBDs created on both sides of the mandible was treated with BCP/FS on one side and BCP/FS loaded with 500ng/ml VEGF on the other side. Two rabbits each from the experimental group and one rabbit each from the control group were sacrificed at 14, 30, 45 and 60 days post operatively. All collected samples from CSBDs-site were subjected to micro computed tomography (µCT) and quantitative and semi-quantitative histological examinations. The results showed that the residual composite was significantly lower at 8 weeks in D (BCP/FS loaded with 500ng/ml VEGF) with more new bone formation compared with other groups. Data collected confirmed the applicability of this novel composite matrix for application in bone regeneration in CSBDs.

Objectives: This study aimed to determine the pattern of fractured zygoma, different treatment modalities, and complications of the treatment in our center. It also aimed to determine the association between the treatment modalities and complication of treatment, and association between number of fixation and complication. Methodology: A retrospective review was conducted from January 2008 until December 2011. All patients diagnosed with zygomatic complex fractured that met the inclusion and exclusion criteria were included in the study. Zingg's Classification was used in the study. Results: The median age was 23.5. Type A was the most common fracture type made up 26.6%. About 90.8% of the injury was caused by road traffic accident. Forty-four patients were treated with open reduction and internal fixation and 4 patients were treated with close reduction only. Fifty patients were treated conservatively. Gillies approach in combination with fixation is the most common procedure accounted for 50%. Three-point fixation at infraorbital, maxillary buttress, frontozygomatic suture, and zygomatic arch was the most common site. However, there were no significant associations between the number of fixation and the occurrence of the complication (P = 0.307). About 29.2% in the treatment group and 66% in the conservative group had complications. About 35.7% of patients in treatment group had complications, while 66% had trismus in conservative group. Conclusion: There was a significant association between types of treatment and the occurrence of complication (P = 0.001). However, there were no significant association between number of fixation and the occurrence of complications (P = 0.307).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
