Objective: The objective of this paper is to provide insights into modern post-traumatic orbital reconstruction from a surgeon's perspective, with a specific focus on adult patients. It aims to highlight the advancements in computer-aided design and manufacturing techniques, particularly in the field of reconstructive orbital surgery, and to introduce the OA² as a tool for improved decision-making in this context.

Methods: The study conducts a comprehensive review of the evolution of reconstructive orbital surgery, focusing on the integration of 3D technology into surgical practices. It also outlines the development and rationale behind the proposed OA2, emphasizing its potential to enhance the accuracy and efficacy of intraorbital reconstruction procedures for post-traumatic deformities.

Results: The review demonstrates the significant progress made in reconstructive orbital surgery, particularly in leveraging 3D technology for virtual modeling, navigation, and the design and manufacturing of patient-specific implants. The introduction of the OA² provides a structured approach to assessing and addressing post-traumatic orbital deformities, offering potential benefits in decision-making and surgical outcomes.

Conclusions: In conclusion, this paper underscores the pivotal role of computer-aided design and manufacturing in advancing reconstructive orbital surgery. It highlights the importance of integrating innovative design concepts into implant manufacturing processes and emphasizes the potential of the OA² to guide surgeons in the management of post-traumatic orbital deformities, ultimately contributing to improved patient outcomes.

Study design: Single-institution retrospective financial analysis.

Objective: Trauma care is consistently linked to inadequate reimbursement, posing a significant financial burden for large trauma centers. Data show that declining Medicare reimbursement rates have indirectly led to declining payment for all procedures covered by insurance. The goals of this study are to investigate the opportunity cost associated with contemporary surgical management of CMF trauma at our institution and to evaluate longitudinal financial trends.

Methods: Patients with operative facial fractures between 2015 and 2022 at Duke University Medical Center were included and compared to patients undergoing general otolaryngology, plastic surgery and oral surgery operations in the same period. Procedural codes, payor type, charges billed, collections, relative value units (RVUs) and other financial data were obtained and analyzed among the 2 patient populations. Comparative analysis was performed to assess the financial trends in data reported previously from 2007-2015.

Results: The collection rate at Duke University Medical Center for operatively managed CMF fractures remains significantly lower than non-CMF counterparts. Interestingly, the collection rate gap between CMF and non-CMF surgeries has narrowed when comparing to the data from 2007-2013. This is largely due to a decrease in collection rates for non-CMF procedures from 29.61% (2007-2013) to 26.57% (2015-2022) [P = 0.0001] and an increase in collection rates for CMF procedures from 17.25% (2007-2013) to 18.05% (2015-2022) [P = 0.0001].

Conclusions: Despite a slight improvement of the gap in reimbursement rates for CMF and non-CMF surgeries over the last several years, trauma care continues to have a negative financial impact on health care institutions.

Study design: Retrospective with follow-up.

Objective: To evaluate the long-term satisfaction of surgically treated patients with zygomaticomaxillary complex (ZMC) fractures in relation to the use of internal fixation, number of fixation points, and orbital floor (OF) reconstruction. Secondary objectives were to describe the use of antibiotics and post-operative infections.

Methods: Patients with unilateral ZMC fractures between 2007-2018 and treatment with either open reduction and internal fixation (ORIF) or closed reduction (CR) were identified from medical records and invited to follow-ups between 2018-2020. Patients were examined, photographed, and completed a questionnaire. A review panel of 3 experienced surgeons evaluated photographs and computed tomography (CT) scans pre- and post-surgery.

Results: The study sample consisted of 136 patients (108 ORIF, 28 CR) with a median follow-up time of 76 months. Patient satisfaction of surgical outcome was high (97.8%), with no significant differences in relation to the use of internal fixation, number of fixation points, or OF reconstruction. Dissatisfaction was primarily related to hypoesthesia. On post-operative CT scans, malar asymmetry was more often predicted in patients with 1-point fixations. On questionnaires and photographs, malar asymmetry was more common in patients with 3-point fixations. Prophylactic antibiotics had no effect on the rate of post-operative infections.

Conclusions: Patient satisfaction was not influenced by internal fixation, number of fixation points, or OF reconstruction. Selected ZMC fractures can be treated with less invasive approaches. Caution should be observed when predicting long-term malar asymmetry on post-operative CT scans. The findings of this study highlight the importance of a rational and ethical use of surgery.

Study design: Retrospective cohort study.

Objective: A major risk factor for oral squamous cell carcinoma (OSCC) is advanced age. Ablative surgery combined with microvascular reconstruction has become routine for OSCC. Nevertheless, there is an interdisciplinary debate about the appropriateness of surgery combined with prolonged general anesthesia in the elderly. In the present study, the ablative and microvascular strategies in OSCC were evaluated in terms of oncologic safety and surgical morbidity in relation to age.

Methods: A total of 345 patients with primary OSCC who underwent ablative tumor surgery and neck dissection according to the German national guideline for OSCC together with microvascular reconstruction from September 2010 to October 2017 were examined. General clinical data was analyzed descriptively with a special focus on perioperative morbidity of an elderly (≥70y) subgroup of 56 patients. Oncological outcome was estimated using Log Rank testing and Kaplan Meier plotting.

Results: Estimated 5 year overall survival (OS) and disease-free survival (DFS) was 69.6% (≥70y) vs. 76.7% (<70y) and 62.9% (≥70y) vs. 78.2% (<70y) respectively with no significant difference between the 2 age groups. In multivariate cox regression, only initial stage of disease revealed significant impact on OS. Analysis of perioperative death/complications, flap loss, operation time, dependence on tracheostomy and hospitalization revealed no significant differences between the 2 groups.

Conclusions: Tumor surgery including neck dissection in combination with primary microvascular reconstruction is a safe therapy in patients of advanced age. This results in excellent oncological outcome with no significant disadvantages in terms of perioperative morbidity, hospitalization or flap failure.

Study design: Retrospective Cohort Study.

Objective: Reconstruction of maxillary bone defects can be completed with vascularized and non-vascularized autografts. Cellular bone matrix allografts (CBMs), which have lineage committed bone cells, has risen as an alternative. The purpose of this study was to describe our experience and to determine the success of CBM based maxillary reconstruction in a variety of clinical scenarios.

Methods: A retrospective cohort study was designed and implemented using data from subjects who presented to the University of Louisville and were treated with a CBM for maxillary reconstruction from 2019 to 2023. Subjects were excluded if they were not treated with a CBM, data were not complete, or postoperative follow-up time was less than 3 months. Descriptive statistics were calculated for each variable. To measure the associations between the risk factors and graft success, Fisher's exact test was implemented. A P-value of <0.05 was considered significant.

Results: The sample included 48 subjects. The mean age of all subjects was 43 ± 24 years. Overall, 42 (87.5%) cases were successful. The perioperative antibiotic administered (P = 0.02), etiology (P = 0.021), and the addition of platelet rich fibrin or autograft as an adjunct influenced CBM success (P = 0.039).

Conclusions: CBMs are a viable option for reconstruction of maxillary bone defects. CBMs may be an alternative to autografts.

Study design: A retrospective study.

Objective: Facial trauma is a prevalent cause of morbidity and mortality with increasing incidence over recent decades. Few studies have examined the prevalence of mental health and substance abuse disorders at the time of diagnosis. Herein we investigate the psychosocial demographics associated with facial trauma.

Methods: The 2016 State Inpatient Database (SID) was used to identify patients with facial trauma from all hospitals in New York, Florida, and Maryland. A non-trauma control group undergoing elective same-day surgeries at ambulatory surgical centers in Florida, Kentucky, Nevada, North Carolina, New York, and Maryland was identified using the State Ambulatory Surgery and Services Database (SASD) from the Healthcare Cost and Utilization Project (HCUP). 777 patients were identified with facial trauma and compared to 500 patients without facial fractures.

Results: Patients with facial fractures were statistically significantly more likely to have a substance abuse disorder (OR 34.78, P < .001) or mental health disorder (OR 2.75, P < .001) compared to controls. Patients with facial fractures were significantly more likely to be black than white (OR 4.80, P < .001). Patients with facial fractures were significantly more likely to have Medicaid compared to Medicare (OR 2.12, P = .005).

Conclusions: Patients with facial fractures are more likely to have premorbid substance abuse and mental health disorders as compared to controls.

Study design: A retrospective study.

Objective: The Markowitz-Manson classification system categorizes nasoorbitoethmoid (NOE) fractures by severity of injury and remaining integrity of the medial canthal tendon. However, this system does not account for direction of bony displacement (in-fracture vs out-fracture), which can greatly affect symptomatology and management. We hypothesize that NOE fractures will present differently based upon their severity: Type I injuries are likely to present with medial nasal bone displacement (in-fracture), whereas Type III fractures will be more prone to lateral displacement (out-fracture).

Methods: A retrospective review was performed for all patients with NOE fractures who were evaluated by the plastic surgery department at a level 1 trauma center over a 6-year period. Computed tomography data were evaluated to assess for directionality of fracture segment displacement. Frequencies of medial, lateral, and non-displacement across NOE types were compared by Chi-Squared Goodness of Fit and Fisher's Exact Tests.

Results: 111 patients met inclusion criteria. The patient population was 73.9% male and averaged 51.2 years old. When bilateral fractures were counted independently, there were 141 cases in total: 115 Type I, 20 Type II, and 6 Type III. Type I fractures were most commonly in-fractured (48.7%), while Type III injuries were consistently out-fractured (100%) (p < .001).

Conclusions: While Type II and III NOE fractures have dominated clinical focus, this study highlights the prevalence of impaction within Type I fractures. These findings advocate for a more comprehensive approach to the evaluation of Type I NOE fractures and their potential risks, including traumatic hypotelorism and nasal airway obstruction.

Study design: Retrospective chart review.

Objective: Socioeconomic status (SES) greatly impacts one's health status and the type of trauma that a patient experiences due to increased risk of exposure and varying availability of resources to treat emergent conditions. There is a need for large-scale databases of pediatric facial trauma to identify discrepancies in occurrence and identify risk factors.

Methods: This retrospective examination uses a multi-center database to evaluate pediatric facial trauma patients (n = 644) visiting Atrium Heath Wake Forest Baptist (AHWFB) hospital from 2020 to 2022. Data collected included demographic information, past medical and surgical history, trauma history, interventions, and long-term outcomes such as scarring, deformities, and sensory or motor deficits. The number of incidents for each zip code surrounding AHWFB was compared with SES data including unemployment rate, mean household income, and poverty level.

Results: Thirty-five percent of patients sustained a high-energy injury, and 65% sustained a low-energy injury. Within the surrounding counties of AHWFB, there were more incidents of pediatric facial trauma in areas with greater rates of poverty (P = 0.006). Additionally, there were more incidents due to high-energy injuries in areas with lower income (P = 0.044) and more poverty (P = 0.002). Specifically, motor vehicle accidents were more common in areas with lower income (P = 0.017) and more poverty (P = 0.001).

Conclusions: These findings in the central Piedmont region of North Carolina are consistent with previous research of SES's effect on health inequalities and serve as evidence of the need to take steps to prevent pediatric facial trauma in areas of low SES.
