The posterior ledge (PL) is a vital structure that supports the implant posteriorly during orbital floor reconstruction. This study describes a technique for mapping the PL in relation to the infraorbital margin (IM) in patients with orbital floor blowout fractures. This study establishes the location of the optic foramen in relation to the PL. Facial computed tomography (FCT) scans of 67 consecutive patients with isolated orbital floor blowout fractures were analyzed using Osirix. Planes of reference for orbital fractures, a standardized technique for performing measurements on FCT, was used. Viewed coronally, the orbit was divided into seven equal sagittal slices (L1 laterally to L7 medially) with reference to the midorbital plane. The distances of PL from IM and location of optic foramen were determined. The greatest distance to PL is found at L5 (median: 30.1 mm, range: 13.5-37.1 mm). The median and ranges for each slice are as follows: L1 (median: 0.0 mm, range: 0.0-19.9 mm), L2 (median: 0.0 mm, range: 0.0-21.5 mm), L3 (median: 15.8 mm, range: 0.0-31.7 mm), L4 (median: 26.1 mm, range: 0.0-34.0 mm), L5 (median: 30.1 mm, range: 13.5-37.1 mm), L6 (median: 29.0 mm, range: 0.0-36.3 mm), L7 (median: 20.8 mm, range: 0.0-39.2 mm). The median distance of the optic foramen from IM is 43.7 mm (range: 37.0- 49.1) at L7. Distance to PL from IM increases medially until the L5 before decreasing. A reference map of the PL in relation to the IM and optic foramen is generated. The optic foramen is located in close proximity to the PL at the medial orbital floor. This aids in preoperative planning and intraoperative dissection.

Craniomaxillofacial Trauma &... Dec 2023Retrospective study.
STUDY DESIGN
Retrospective study.
OBJECTIVE
To evaluate patient demographics, surgical management, and complications of orbital and orbitozygomaticomaxillary complex (OZMC) fractures treated at a district hospital in Norway.
METHODS
The medical records of patients with orbital fractures treated at Aalesund hospital between January 2002 and July 2017 were reviewed. Data on demographics, signs and symptoms, cause of injury, fracture type, associated fractures, surgical management, and complications were collected.
RESULTS
A total of 36 patients were reviewed. Males predominated (1:4.1), and fractures occurred mostly in patients 40-59 years (mean 41.8 years). Interpersonal violence was the leading cause of injury, followed by falls. Alcohol was significantly associated with assault caused fractures ( .001). Orbitozygomaticomaxillary fractures were the most frequent, followed by pure orbital fractures. Clinical findings included periorbital ecchymosis (72%), swelling (56%), sensory nerve dysfunction (53%), diplopia (22%), and restricted eye motility (22%). Commotio cerebri was observed in more than half of our sample and 47% had other facial bone fractures. Referral to tertiary hospitals was done in 19% of the cases. The main treatment done was open reduction and internal fixation (ORIF) (45%). Infection was diagnosed in 17% and managed with antibiotics.
CONCLUSIONS
The incidence of orbital and OZMC fractures in Moere and Romsdal county in western Norway was low, occurring mainly in males over 40 years. The mechanism of injury was predominantly interpersonal violence and falls. A high proportion of the sample had minor traumatic brain injury (mTBI).

Seminars in Ophthalmology Aug 2023We describe the clinical settings and the factors predicting outcomes in open globe injuries with concurrent orbital fractures.
AIM
We describe the clinical settings and the factors predicting outcomes in open globe injuries with concurrent orbital fractures.
METHODS
Retrospective, consecutive, non-comparative study. All eyes from January 2014 to January 2021 with concurrent open globe injuries with orbital fractures that underwent management were included. The clinical data of each patient who underwent a comprehensive ophthalmic examination was entered into a browser-based electronic medical records system (eyeSmart EMR) by uniformly trained ophthalmic personnel and supervised by an ophthalmologist using a standardized template. Favorable functional outcome was defined as the final best corrected visual acuity of >20/200 as per the World Health Organization (WHO) definitions of severe visual impairment and blindness. A favorable anatomic outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. Multivariate logistic regression analysis was done to assess the effect of various demographic and clinical factors and the type of orbital fracture on the final anatomic and functional outcome.
RESULTS
Ninety-one eyes of 91 patients were included in the study. Females accounted for 74/91 (81.3%) of the eyes. Modes of trauma was rupture in 67%, perforating in 5.5% and penetrating in 27.5% of the cases. Orbital rim involvement was seen in 79.1%. The most common isolated fracture seen was a medial wall (19.78%), which was followed by the orbital floor (15.38%). Favorable functional outcome was seen in 10 eyes (11%), while a favorable anatomic outcome was achieved in 45 (49.5%). Odds of a favorable functional outcome were 6.12 (95% CI 1.22 to 30.71), p = .02 for an open globe injury with orbital fracture in the absence of a concurrent retinal detachment. Odds of a favorable anatomic outcome were 55.55 (95% CI 2.43 to 1250), p = .01 when the injury did not involve zone 3, 9.94 (95% CI 2.05 to 48), p = .004 when concurrent retinal detachment was absent, 16.3 (95% CI 1.42 to 187.19), p = .02 when the orbital rim was intact and 7.83 (95% CI 1.09 to 56.19), p = .04 when only one orbital wall was involved.
CONCLUSIONS
Open globe injuries with concurrent orbital fractures result in a very poor functional outcome. Concurrent retinal detachment is a negative predictive factor. Associated fractures involving the orbital rim increase the risk of eyeball loss.

Orbital floor fractures are routinely encountered in facial trauma. Many factors influence the final outcome of the orbital floor surgery, time interval and the extent of other facial bone fractures are the two factors which can significantly influence the postoperative outcome following orbital floor reconstruction. Our study aims to find the ideal time for intervention and the association of other factors in the final outcome of orbital floor reconstruction. A retrospective and prospective cohort study of patients who were operated at Pondicherry Institute of Medical Sciences for orbital floor fractures, between 2011 January and 2017 July. All the data were entered on an Excel work sheet and statistically analyzed. In our study 8 patients (8/29, 27.58%) had diplopia prior to surgery, 5 patients (5/29, 17.24%) had complete recovery following surgery and 3 patients (3/29, 10.34%) had persistence of diplopia postoperatively. Patients with diplopia operated prior to 7 days were found to have significant improvement in postoperative diplopia. Patients with 5 or more facial fractures were found to have persistence of diplopia, infraorbital numbness, and enophthalmos postoperatively. Our study suggests that early intervention, before 7 days improves the outcome in patients with diplopia and provides a better result postoperatively. In our study preoperative diplopia and infraorbital numbness and postoperative persistence of enophthalmos, diplopia, and paresthesia were found more in patients with 5 or more facial bone fractures. Our study suggests a poor postoperative outcome when 5 or more facial bones are fractured.

BACKGROUND
Superior orbital rim fractures are challenging fractures as they often concomitantly occur with additional calvaria fractures. Virtual surgical planning (VSP) has been underutilized in this area of craniomaxillofacial trauma for reconstruction.
PURPOSE
The purpose of this study is to qualitatively describe the use of VSP and anatomically perfected stereolithic models in treatment of superior orbital rim fractures in combined neurosurgery/oral and maxillofacial surgery cases.
STUDY DESIGN, SETTING, SAMPLE
This study is a retrospective case series of subjects who were treated at the Massachusetts General Hospital (July 2022 to November 2022). Inclusion criteria include subjects who had both calvaria and maxillofacial injuries requiring concurrent operative intervention on their superior orbital rim fractures and the use of VSP.
PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE
Not applicable.
MAIN OUTCOME VARIABLE
The outcome variable of interest is the difference in the planned position of the orbital rim repair compared to the actual position achieved.
COVARIATES
None.
ANALYSES
Heat map analysis was used to compare the difference in the planned position versus the actual position achieved.
RESULTS
There were six orbits (five subjects, mean age 33.8 ± 21.49 years) that met the criteria. The mean difference in planned versus actual orbital volume achieved was 2.52 ± 2.48 cm. The superimposition of the postoperative scan to the planned simulation revealed 84% ± 3.27% of the voxel surface was within +2 and -2 millimeters of its planned position.
CONCLUSION AND RELEVANCE
This study has demonstrated the use of VSP in combined neurosurgery and oral and maxillofacial surgery procedures in the fixation of superior orbital rim fractures. This case series highlights that the postoperative position achieved in the six orbits was within 84% of the planned position.

BACKGROUND
We aimed to retrospectively measure the incidence of missed orbital blowout fracture diagnosis in primary examinations of patients with surgically treated fractures, to identify the causes of the diagnostic oversight, and to describe the clinical manifestations of the fractures.
MATERIAL AND METHODS
A retrospective cohort of all patients with unilateral orbital blowout fractures who underwent subsequent surgical fracture reduction at the Department of Oral and Maxillofacial Diseases, Helsinki University Hospital, from January 2011 to July 2021, was gathered. Demographics, fracture type, associated injuries, clinical manifestations, reconstruction indication, diagnostic delay, and causes of fractures were analysed. For statistical analysis, Fisher's exact test, unpaired t-test, and the Wilcoxon Rank Sum were used. Significance was set at P˂0.05.
RESULTS
Fracture diagnosis was missed in 26 (13%) of 207 patients: in 40% of patients aged under 18 years and in 10% of patients aged 18 years or over (P=0.005). Suboptimal eye examination was found in 62% of patients with missed fracture and in 13% of those with timely diagnosis (P<0.001). Adjusted odds ratios for missed diagnosis in patients aged under 18 years versus patients aged 18 years and over was 9.3 (95% CI 2.4-35) and in patients with suboptimal versus sufficient eye examination 13.6 (95% CI 5.1-37). More common clinical manifestations in patients aged under 18 years were diplopia or restricted eye movements (P=0.005), pain in eye movements (P=0.010), nausea and/or vomiting (P<0.001), and bradycardia (P=0.014); periorbital haematoma was rarer (P<0.001). Suboptimal eye examination was involved in 62% and misinterpretation of computed tomography images in 50% of missed fractures, together explaining 85% of cases.
CONCLUSIONS
Orbital blowout fractures are often missed in primary examination, especially in children and adolescents, who also present with subtler clinical manifestations. While the diagnosis can be difficult, appropriate clinical and radiological examination will reveal most cases.

BACKGROUND
The aim of this study was to examine the incidence and demographic characteristics of patients with orbital walls fractures who were treated in the department of oral and maxillofacial surgery of a tertiary hospital in Jordan.
MATERIAL AND METHODS
A retrospective cohort study of patients with a diagnosis of with selected orbital walls fracture was designed and implemented, during a two-year period between January 2020 and December 2021. Information on patients treated for orbital walls fractures were retrieved and analyzed regarding age, sex, etiology, anatomical site, and treatment modality. Descriptive data presented as simple frequencies and percentages.
RESULTS
A total of 76 patients with 100 orbital wall fractures, age range was 4-68 years old with a mean age 28 (SD±12), of whom were 53 (69.7%) were male and 23(30.3%) were female, with male:female ratio was 2:1. The most common etiology of all orbital walls fractures was RTA in 47 patients (61.8%; ≤0.021), followed by violence in male patients. The most prevalent age-group was 21-30 years old with 16 patients (21.05%; ≤0.235), and single orbital wall fractures 56 (56%) were more common than combined orbital wall fractures.
CONCLUSIONS
In conclusion, this study will contribute to identifying the best clinical therapy and protective techniques for individuals with orbital fractures. Orbital fracture, Etiology, Orbital trauma, Road traffic accidents, Trauma.
