Review
INTRODUCTION
Fractures of the orbit are common injuries within the maxillofacial skeleton, and can often result in restrictions to ocular movement, diplopia, and enophthalmous if herniation of globe content occurs. Various studies have demonstrated the use of autologous cartilage grafts in the reconstruction of orbital fractures.
METHODS
A systematic review protocol was registered with PROSPERO, and reported in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses. Comprehensive electronic search strategies of four databases were developed. Studies were screened according to the inclusion and exclusion criteria by two independent reviewers.
RESULTS
Seven thousand one hundred seventy-one articles were identified following a comprehensive literature search. These articles were filtered for relevance and duplication, which reduced the number of articles to 16. A total of 259 patients underwent orbital reconstruction with the use of autologous cartilage. Conchal cartilage was harvested in 148 patients, auricular cartilage in 22 patients, nasoseptal cartilage in 72 patients, and costal cartilage in 17 patients. Thirty, seven, twelve, and four complications were observed in patients where cartilage was harvested from the concha, auricle, nasoseptum and rib, respectively. Most common complications included diplopia (=23), infra-orbital para/anaesthesia (=27), and enophthalmos (=7). No failure of graft or donor site morbidity were observed in the studies.
CONCLUSION
Autogenous materials such as cartilage can be used as an alternative for orbital reconstruction. Cartilage was considered by the authors to provide adequate structural support to the orbital contents, and that it was easy to harvest, shape, and position.

INTRODUCTION
Midface fracture incidence and trauma patterns vary across countries, due to socioeconomic, environmental, and cultural factors. The aim of this retrospective study was to assess the etiology, pattern, and treatment of midface fractures in North of Jordan during 2018-2021.
METHODS
This single-center retrospective study was based on the review of the medical records of patients who had suffered midface fractures and were treated at the Department of Oral and Maxillofacial Surgery at the King Abdullah University Hospital. The dataset for this investigation spanned the 4-year period from January 2018 to December 2021.
RESULTS
During the 4-year period, 267 patients presented with 376 different maxillofacial fractures. Of those, 140 patients had 250 midface fractures, with a mean of 1.79 per patient. Their age ranged from 2 to 68 years (mean [standard deviation] = 25.8 [12.0] years). The most frequent injury cause was road traffic accidents (RTA) ( = 72, 51.3%), followed by falls ( = 27, 19.3%). Among midface fractures, the most frequent were orbit fractures (42.4%), followed by zygomatic fractures (31.6%) and maxillary fractures (26%). The majority of fractures (77.9%) were treated through open reduction and internal fixation (ORIF), while the remaining (15.7%) required closed reduction and conservative treatment was sufficient in 6.43% of fractures.
CONCLUSIONS
Midface fractures were more common among males, and primarily occurred in the orbital floor due to the high incidence of RTAs. Maxillary fractures were mostly of the LeFort I Type and ORIF was the most common treatment modality.

Orbital apex fractures are a debilitating condition that can cause vision problems and are often associated with intracranial injury. Traumatic Optic Neuropathy (TON), which results in vision loss following a traumatic injury to the optic nerve, can be caused by various mechanisms, but most cases involve injuries to the globe, orbit, or adnexa. We are reporting a case of an 18 year old male with a history of an air gun being accidentally discharged into his left eye. He was evaluated and found to have an Orbital apex fracture with left eye TON. Patient was administered high dose steroids. Detailed evaluation by Ophthalmology revealed a left eye traumatic stage I macular hole which was conservatively treated with visual improvement reported during patient follow up.

OBJECTIVES
Many orbital fracture patients are transferred to tertiary care centers for immediate ophthalmology consultation, though few require urgent ophthalmic evaluation or intervention. This overutilizes limited resources and overburdens patients and the health care system with travel and emergency department (ED) expenses. A simple, easy-to-use, clinical decision-making tool is needed to aid local EDs and triage services in effectively identifying orbital fracture patients who need urgent ophthalmic evaluation.
DESIGN
Single center, retrospective cohort study.
SUBJECTS
Orbital fracture patients aged ≥ 18 years who presented to the study institution's emergency department and received an ophthalmology consultation.
METHODS
Ocular injuries that required close monitoring or an intervention within the first few hours after presentation were termed urgent. Two Hawkeye Orbital Fracture Prioritization and Evaluation (HOPE) algorithms were developed to identify orbital fracture patients needing urgent evaluation; including 1 algorithm incorporating computerized tomography (CT) scans interpreted by ophthalmology (HOPE+CT). Algorithms were compared with 3 previously published protocols: the University of Texas Health Science Center at Houston (UTH), the South Texas Orbital Fracture Protocol (STOP), and Massachusetts Eye and Ear (MEE) algorithms.
MAIN OUTCOME MEASURES
Correct triage of patients with orbital fractures who have urgent ocular or orbital conditions.
RESULTS
In the study institution's ED, 134 adult patients (145 orbits) were seen with orbital fractures in 2019. Eighteen (13.4%) had ocular or orbital conditions categorized as urgent. The HOPE tool resulted in 100% sensitivity and 78.4% specificity. The HOPE+CT tool resulted in 100.0% sensitivity and 94.0% specificity. The UTH algorithm was 91.7% sensitive and 76.5% specific. South Texas Orbital Fracture Protocol and MEE were both 100% sensitive but only 35.1% and 32.8% specific, respectively.
CONCLUSIONS
The HOPE and HOPE+CT algorithms were superior or equal to the UTH, STOP, and MEE algorithms in terms of specificity while detecting all urgent cases. Implementation of a triage protocol that uses the HOPE or HOPE+CT algorithms could improve resource utilization and reduce health care costs through identification of orbital fracture patients needing urgent evaluation. An online tool that deploys the HOPE+CT algorithm in a user-friendly interface has been developed and is undergoing prospective validation before public dissemination.

PURPOSE
To investigate the effect of antithrombotics on the occurrence of maxillofacial haemorrhagic symptoms, and to determine if these haemorrhagic symptoms are predictors of maxillofacial fractures.
METHOD
A prospective cohort study was conducted of consecutive patients with maxillofacial trauma who had been admitted to the emergency department of four hospitals in the Netherlands. This study compared five haemorrhagic symptoms (peri-orbital haematoma, raccoon eyes, epistaxis, subconjunctival ecchymosis, and intra-oral haematoma) between patients not-using (NUA) and using (UA) of antithrombotics, and whether these maxillofacial haemorrhagic symptoms served as predictors for maxillofacial fractures.
RESULTS
Out of the 1005 patients, 812 (81%) belonged to the NUA group, and 193 (19%) to the UA group. UA patients exhibited higher frequencies of peri-orbital hematoma (54% vs. 39%, p < 0.001), raccoon eyes (10% vs. 5%, p = 0.01), and subconjunctival ecchymoses (16% vs. 7%, p < 0.001). In NUA, peri-orbital hematoma (OR = 2.5, p < 0.001), epistaxis (OR = 4.1, p < 0.001), subconjunctival ecchymosis (OR = 2.3, p = 0.02), and intra-oral hematoma (OR = 7.1, p < 0.001) were significant fracture predictors. Among UA, peri-orbital hematoma (OR = 2.2, p = 0.04), epistaxis (OR = 5.4, p < 0.001), subconjunctival ecchymosis (OR = 3.7, p = 0.008), and intra-oral hematoma (OR = 22.0, p < 0.001) were significant fracture predictors.
CONCLUSION
Maxillofacial haemorrhagic symptoms were observed more frequently in the UA group than in the NUA group. However, in both groups, maxillofacial haemorrhagic symptoms appear to be predictors of maxillofacial fractures. Caution is warranted in attributing these symptoms solely to antithrombotic use during emergency department assessments.

BACKGROUND
Tertiary hyperparathyroidism describes the autonomous and excessive secretion of parathyroid hormone (PTH) by the parathyroid glands after longstanding secondary hyperparathyroidism in chronic kidney disease. Brown tumors are a sign of uncontrolled hyperparathyroidism. In this case, we have reported a refractory and destructive hyperparathyroidism storm. Also, it presented with atypical onset and unexpected adenoma location.
CASE PRESENTATION
A 37-year-old man was diagnosed with end-stage kidney disease 22 years ago. He has been undergoing dialysis treatment since that time. Recently, he was admitted to the ophthalmology department due to the unilateral anterior bulging of the right eye and drooping of the eyelid. Magnetic resonance imaging exhibited an extraconal mass lesion located in the right orbital posterior superolateral position. Computerized tomography scans considered expansile bone lesion with peripheral calcification and originating from the sphenoid wing. The bone mass lesion was resected via craniotomy due to the compressive effect. The pathological findings were consistent with brown tumors. Plasma intact PTH level was 4557 pg/mL. The patient informed that he underwent parathyroidectomy and two leg fractures operation in a medical query. Parathyroid scintigraphy determined three distinct foci consistent with adenomas and one of them was in mediastenum. Second parathyroidectomy was recommended to the patient but the patient refused surgery. Despite his medication and dialysis regimen being revised, PTH levels were maintained at higher levels in follow-up.
CONCLUSIONS
We presented a hyperparathyroidism case that was resistant to all treatments and exhibited all the severe complications in a long-term dialysis patient. Furthermore, this case has revealed the importance and difficulty of secondary hyperparathyroidism management.

BACKGROUND
One-point fixation was superior to the two and three-points fixation in minimally displaced zygomaticomaxillary complex (ZMC) fracture regarding the cost, invasiveness, scaring, number of wounds, and operation time. Accordingly, this study aimed to predict which one-point fixation is the most stable in managing minimally displaced ZMC fracture.
MATERIAL & METHODS
This study simulated the different one-point fixation approaches on three ZMC models after fracture reduction and application of all forces exerted on the fractured area. The findings were represented as stress impact on the ZMC fracture and plating system as well as the inter-fragments micro-motion.
RESULTS
The von misses stresses of plates for the zygomaticofrontal, infra-orbital rim, and zygomaticomaxillary buttress model were (66.508, 1.285, and1.16 MPa) respectively. While the screws' von misses for the infraorbital rim, zygomaticofrontal, and zygomaticomaxillary buttress models were (13.8, 4.05, and 1.60 MPa) respectively. Whereas, the maximum principles stress at zygomaticofrontal, zygomaticomaxillary buttress, and infraorbital rim models were (37.03, 37.01, and 34.46 MPa) respectively. In addition, the inter-fragment micro-motion for zygomaticomaxillary buttress, infraorbital rim, and zygomaticofrontal models were (0.26, 0.25, and 0.15 mm) respectively.
CONCLUSION
One-point fixation at zygomaticomaxillary buttress is the preferred point because it is exposed to low stresses, and the inter-fragment micro-motion is within the approved limit with the elements in the same direction of fixation which indicates the rigid fixation. In addition, it is less palpable and scarless.

Retrospective radiological analysis to establish anatomical variation in angulation between medial canthus and the middle turbinate, for optimal positioning of Lester Jones Lacrimal bypass tubes in treatment of Epiphora.
PURPOSE
To determine the optimum angle for placement of Lester Jones lacrimal bypass tube using fixed radiological markers on CT scan head with axial and coronal cuts, as well as analysing the anatomical variation and range of angulation between individuals within our local population.
METHODS
A retrospective radiological study conducted on a randomly selected sample of 384 adult patients in a UK Teaching Hospital. The angle between the medial canthus and the middle turbinate was measured on CT scans of the head using fixed radiological anatomical landmarks and analysed using the IMPAX software. Patients with orbital or nasal fractures, as well as those with history of surgical procedures involving the facial bones, were excluded. The accuracy of our measurements was validated using three dimensional (3D) CT head reconstruction technology.
RESULTS
Analysis of the results showed a range of angulation between 28-45 degrees, with a mean angle of 36.99 ± 4.78 SD. There was no significant correlation found when comparing the different age groups using the One Way ANOVA test. Furthermore, a non-significant correlation was found between males and females when their mean angles were compared using the independent t-test.
CONCLUSION
Our study showed that the ideal angle for insertion of Lester Jones tube would be between 30-45 degrees, with a mean of 37 degrees. No significant correlation was found between the age of the patient and the ideal angle of insertion of Lester Jones tube. Moreover, no significant difference was found in the angle measurements between males and females.
