Introduction Traumatic facial injuries, leading to facial fractures represent a significant subset of traumatic events, with age emerging as a crucial determinant influencing both their etiology and outcomes. Understanding the age-related patterns of traumatic facial fractures is essential for developing targeted prevention and management strategies. In this context, the Appalachian tri-state area stands as an underexplored region concerning this issue, necessitating comprehensive research to elucidate the nuances of age-related traumatic facial fractures within this geographic context. Methods This retrospective study delves into the age-related patterns of traumatic facial fractures within the Appalachian tri-state area, drawing upon patient records from Cabell Huntington Hospital and Saint Mary\'s Medical Center spanning a five-year period. The study cohort encompasses 623 patients categorized into three age groups: individuals aged <22 years, those aged 22-65 years, and individuals over 65 years. Data analysis involves meticulous examination of mechanisms of injury, injury severity scores (ISSs), hospital length of stay, and the prevalence of surgical interventions across different age cohorts. Results Out of 623 patients, 104 (16.7%) were under 22 years old, 367 (58.9%) were between 22 and 65 years old, and 152 (24.4%) were over 65 years old. The majority were male (70%). Falls were the most common cause of facial fractures in patients over 65 (78%), while assaults were predominant in the 22-65 age group (24%), and motor vehicle collisions (MCVs) in those under 22 (34%). The median ISS and hospital stay durations were similar across age groups. 28% of patients underwent surgery, with significant variation among age groups (p<0.001): 38% for <22 years, 33% for 22-65 years, and 11% for >65 years. Mandibular fractures were more prevalent in younger patients, with rates of 12% for <22 years compared to 5.3% for >65 years. Logistic regression analysis revealed that patients aged 22-65 had 4.10 times higher odds (95% CI=2.38, 7.45, p<0.001) of undergoing surgery, while those under 22 had 5.14 times higher odds (95% CI=2.73, 10.0, p<0.001) compared to those over 65. Significant associations were found for mandibular and bilateral mandibular outcomes in patients aged 22-65 years. Discussion These findings underscore the imperative for tailored prevention strategies and age-specific treatment protocols to optimize patient outcomes. Fall prevention initiatives for the elderly and interventions addressing sports-related injuries for younger individuals are paramount. Moreover, the study highlights the necessity of specialized care protocols for elderly patients to minimize hospital stay durations and manage age-related comorbidities effectively. Moving forward, further research should address limitations, validate findings, and explore the efficacy of specific interventions, thereby paving the way for enhanced preventive measures and management strategies tailored to the diverse age cohorts affected by traumatic facial fractures in the Appalachian region.

OBJECTIVE: The orbital floor is frequently involved in head trauma. Current evidence on the use of reconstruction materials for orbital floor repair is inconclusive. Accordingly, this study aimed to compare the impact of polydioxanone (PDS) foil thickness on reconstruction of the orbital geometry after isolated orbital floor fractures.
METHODS: Standardized isolated orbital floor fractures were symmetrically created in 11 cadaver heads that provided 22 orbits. PDS foils with thicknesses of 0.25-0.5 mm were inserted. Computed tomography (CT) scans of the native, fractured, and reconstructed orbits were obtained, and orbital volume, orbital height, and foil bending were measured.
RESULTS: Orbital volume and height significantly (p < 0.01) increased after the creation of isolated orbital floor fractures and significantly (p = 0.001) decreased with overcorrection of the orbital geometry after orbital floor reconstruction with PDS 0.25 mm or PDS 0.5 mm. The orbital geometry reconstruction rate did not differ significantly with respect to foil thickness. However, compared to PDS 0.5 mm, the use of PDS 0.25 mm resulted in quantitatively higher reconstructive accuracy and a restored orbital volume that did not significantly differ from the initial volume.
CONCLUSIONS: Orbital floors subjected to isolated fractures were successfully reconstructed using PDS regardless of foil thickness, with overcorrection of the orbital geometry. Due to its lower flexural stiffness, PDS 0.25 mm appeared to provide more accurate orbital geometry reconstruction than PDS 0.5 mm, although no significant difference in reconstructive accuracy between PDS 0.25 mm and PDS 0.5 mm was observed in this cadaveric study.

BACKGROUND: Effective surgical access to the orbital floor facilitates surgery and mitigates postoperative complications (PC). The aim of this study was to compare PC between the preseptal and retroseptal transconjunctival approaches (PS-TCA/RS-TCA) for isolated orbital floor fracture (OFF).
METHODS: Using a double-blind, non-inferiority, randomized, split-face study design, patients aged ≥ 18 years with bilateral isolated OFF were enrolled. A sample size of 177 eyes per group was determined through power analysis. The primary predictor variable was the surgical approach, and the main outcome was the PC rate at month 6. Statistical analyses were computed with a significance level at 0.05 and the non-inferiority margin at a relative risk (RR) of 0.045.
RESULTS: The final sample included 193 patients (23.3 % female; age, 42.8 ± 18.1 years). Both TCA variants exhibited comparable PC rates (5.2 % for PS-TCA vs. 7.3 % for RS-TCA; P = 0.53; absolute risk, +2.07 % [95 % CI, -2.74 % to 6.89 %]; RR, 1.4 [95 % CI, 0.64 to 3.07]). Approximately one in every 49 patients experiencing PC with RS-TCA (number needed to harm, 48.3).
CONCLUSIONS: Both TCA methods can be used without different PC rates at 6 months postoperatively. Future research should focus on TCA in combination with other surgical approaches for multiple orbital wall reconstruction.

Fractures of the orbit are frequently noted in craniomaxillofacial trauma. The complexity of the anatomy and the proximity to various vital structures often complicates the surgical management of these fractures. The authors have thus attempted to review the literature on anatomy of the bony orbit and its soft tissue envelope in a simplified manner with due emphasis on surgical anatomy and exploration of the orbit with a surgical perspective. The contents of this narrative literature review may be useful for young maxillofacial surgeons and will aid in the process of management of orbital fractures.

BACKGROUND: Traffic trauma can lead to ocular damage. Open globe injuries usually have a poor prognosis, which can be ameliorated by prompt diagnosis and appropriate treatment. Nonetheless, few studies have focused on the visual outcomes of patients following traffic accidents. In this study, we aimed to examine the characteristics and prognosis of ocular complications in patients following traffic accidents at a specialized tertiary eye hospital.
METHODS: We classified 44 patients from traffic accidents (88 eyes) into groups with equal or better (better group) and worse (worse group) corrected-distance visual acuity than a logarithm of the minimum angle of resolution 0 at the initial presentation. Final corrected-distance visual acuity, intraocular pressure, corneal injury, presence of traumatic cataracts, and treatment were compared between the groups. In addition, a multivariate linear regression analysis was performed to identify factors associated with the final visual acuity.
RESULTS: Globe contusion, orbital blowout fracture, traumatic iritis, and trochlear nerve palsy were observed in 14.8%, 3.4%, 2.3%, and 2.3% of the patients, respectively. Topical instillation and ophthalmological treatment/surgery were performed in 17.0% and 9.1% of the patients, respectively. The better group (68 eyes) had significantly better final visual acuity than the worse group (20 eyes) (P < 0.001). However, there was no between-group difference in demographic characteristics. Multivariate analysis demonstrated that there was a significant correlation between the initial and final visual acuities (P < 0.001).
CONCLUSIONS: Assessing visual acuity at the initial presentation is crucial for predicting the final visual acuity. Our findings will help to inform ophthalmologists aiming to improve the prognosis and treatment of ocular trauma in patients following traffic accidents.

Orbital fractures in the pediatric population are rare. A trapdoor fracture is a special anatomic type of orbital fracture associated with herniation of orbital contents and entrapment of extraocular muscles entrapment with no signs of any soft tissue trauma. A delay in diagnosis can lead to a life-threatening condition known as oculocardiac reflex, characterized by nausea, vomiting, bradycardia, and syncope. Many authors recommend early surgical intervention, but some patients may delay for various reasons. We hereby represent three cases of orbital fracture to prevent long-term persistent diplopia. Depending on the case scenario, two cases were operated on in which an autogenous iliac cortical graft was placed in one patient to prevent postoperative herniation of orbital content, and in one patient, only release of entrapped muscles was done. One patient was managed conservatively with a regular follow-up visit.

OBJECTIVE: To determine risk factors for substantial closed-globe injuries in orbital fractures (SCGI) and to develop the best multivariate model for the prediction of SCGI.
METHODS: A retrospective study was performed on patients diagnosed with orbital fractures at Farabi Hospital between 2016 and 2022. Patients with a comprehensive ophthalmologic examination and orbital CT scan were included. Predictive signs or imaging findings for SCGI were identified by logistic regression (LR) analysis. Support vector machine (SVM), random forest regression (RFR), and extreme gradient boosting (XGBoost) were also trained using a fivefold cross-validation method.
RESULTS: A total of 415 eyes from 403 patients were included. Factors associated with an increased risk of SCGI were reduced uncorrected visual acuity (UCVA), increased difference between UCVA of the traumatic eye from the contralateral eye, older age, male sex, grade of periorbital soft tissue trauma, trauma in the occupational setting, conjunctival hemorrhage, extraocular movement restriction, number of fractured walls, presence of medial wall fracture, size of fracture, intraorbital emphysema and retrobulbar hemorrhage. The area under the curve of the receiver operating characteristic for LR, SVM, RFR, and XGBoost for the prediction of SCGI was 57.2%, 68.8%, 63.7%, and 73.1%, respectively.
CONCLUSIONS: Clinical and radiographic findings could be utilized to efficiently predict SCGI. XGBoost outperforms the logistic regression model in the prediction of SCGI and could be incorporated into clinical practice.

OBJECTIVE: To analyze the types and causes of complications following orbital fracture reconstruction and enhance clinicians\' capacity to manage or prevent such complications.
METHODS: We conducted a retrospective case series analysis, retrospectively collecting and analyzing clinical data of patients with orbital fractures who received surgical treatment at the Affiliated Eye Hospital of Nanchang University from May 2012 to May 2022. Descriptive statistics were employed to document common postoperative complications, and we recorded complications persisting after a minimum 6-month follow-up period.
RESULTS: Among the 227 patients who underwent orbital fracture surgery, they were followed up for 6 to 36 months, and complications occurred in 15 cases, resulting in an incidence rate of 6.61%. These complications included implant material infections and rejections (4 cases), persistent diplopia (3 cases), intraorbital hematomas (2 cases), epiphora (2 cases), lower eyelid eversion or retraction (2 cases), and skin scars (2 cases). The primary cause of postoperative infection was chronic inflammation in the paranasal sinuses or closed cavities within the fracture area. Postoperative complications in orbital fractures were associated with various factors, including the timing of surgery, surgical approach, repair materials, surgical skills, and auxiliary techniques.
CONCLUSIONS: Standardizing surgical techniques and implementing precise auxiliary technologies may reduce the incidence of complications and enhance the operation\'s success rate.

OBJECTIVE: This pilot study aims to evaluate the feasibility and effectiveness of computer-assisted surgery protocol with 3D-preformed orbital titanium mesh (3D-POTM), using presurgical virtual planning and intraoperative navigation in primary inferomedial orbital fracture reconstruction.
METHODS: Between March 2021 and March 2023, perioperative data of patients undergoing surgery for unilateral inferomedial orbital fracture treated with 3D-POTM were analyzed. Presurgical virtual planning with a Standard Triangle Language file of preformed mesh was conducted using the mirrored unaffected contralateral side as a reference, and intraoperative navigation was used. The reconstruction accuracy was determined by: correspondence between postoperative reconstruction mesh position with presurgical virtual planning and difference among the reconstructed and the unaffected orbital volume. Pre- and postoperative diplopia and enophthalmos were assessed.
RESULTS: Twenty-six patients were included. Isolated orbital floor fracture was reported in 14 (53.8%) patients, meanwhile medial wall and floor one in 12 (46.1%) cases. The mean difference between final plate position and ideal digital plan was 0.692 mm (95% CI: 0.601-0.783). The mean volume difference between reconstructed and unaffected orbit was 1.02 mL (95% CI: 0.451-1.589). Preoperative diplopia was settled out in all cases and enophthalmos in 19 (76.2%) of 21 patients.
CONCLUSIONS: The proposed protocol is an adaptable and reliable workflow for the early treatment of inferomedial orbital fractures. It enables precise preoperative planning and intraoperative procedures, mitigating pitfalls and complications, and delivering excellent reconstruction, all while maintaining reasonable costs and commitment times.

UNASSIGNED: Foreign body reaction to non-absorbable alloplastic orbital implants utilized for bony reconstruction are infrequently documented in the literature. We present the workup and surgical management of a giant cystic mass encapsulating a patient\'s alloplastic orbital implant, which was ultimately deemed to be a result of foreign body reaction.
UNASSIGNED: A 41-year-old male patient with distant history of a right orbital floor fracture had undergone repair with the placement of a nylon foil implant. The patient presented twenty years later with progressive ipsilateral globe proptosis and was found to have a giant inferior orbital cyst. Surgical exploration and removal of the implant and capsule were performed. Histopathology confirmed a delayed foreign body reaction around the patient\'s alloplastic implant.
UNASSIGNED: Alloplastic implants may result foreign body reaction and cyst encapsulation as a delayed complication.
