Background: There is no consensus on the “best” sequencing for open reduction and internal fixation (ORIF) in multiple mandibular fractures involving the condyle. Objective: The objective of this study is to compare the outcomes between a “top-to-bottom” and a “bottom-to-top” ORIF sequence for multifocal mandibular fractures at the author’s institution. Patients and Methods: A retrospective cohort study of adult dentate patients with multifocal mandibular fractures treated with ORIF. Inclusion criteria were the presence of at least one condylar neck or basis fracture and one “non-condylar” mandibular fracture. The authors evaluated the reduction quality using radiological and clinical parameters, including the ramus/condylar neck angle, the presence of a gap at the lingual aspect in the dentate area, dental occlusion, the need for a redo operation, and the need for postoperative occlusal fine-tuning. Results: A total of 31 patients had a bottom-to-top sequence, 4 patients had a substandard outcome, 4 had an acceptable outcome, and 23 achieved an ideal outcome. Ten patients underwent a top-to-bottom sequence; one patient had an acceptable outcome, and nine patients achieved ideal outcomes. There was no significant difference between sequencing and outcome. (p = 0.231). However, the odds ratio for a suboptimal outcome regarding the bottom-to-top surgery as opposed to the top-to-bottom surgery was 4.80 (CI: 0.53–236.07). In other words, the odds of having a suboptimal outcome and a bottom-to-top sequence were 4.80 times higher than having a suboptimal outcome and a top-to-bottom sequence. Conclusions: Based on our results, the top-to-bottom ORIF sequence appeared to be a favorable factor. Full article

Background: This study aims to evaluate the use of the endoscopic transorbital approach for reducing frontal sinus fractures and compare its outcomes with the traditional bicoronal approach. Methods: A retrospective comparative analysis of case studies including all patients with frontal sinus fractures treated at our institution between January 2013 and December 2023 was conducted. Patients were categorized based on treatment approach (through traumatic laceration, bicoronal, or endoscopic transorbital). For the comparative analysis, cases with associated maxillofacial fractures or cerebrospinal fluid (CSF) leakage were excluded. Results: Out of 133 patients, 35 underwent surgery, with 6 patients treated using the endoscopic transorbital approach. This group of patients treated with the transorbital endoscopic approach demonstrated significantly shorter operative times compared to the bicoronal approach (mean 102 vs. 168 min, p = 0.021). They also had only minor complications, including temporary hypoesthesia and one transient ptosis. One patient had a minimal residual defect. The technique has been concluded to require endoscopic expertise. Conclusions: The endoscopic transorbital approach is a safe, minimally invasive alternative to the bicoronal approach for selected anterior wall frontal sinus fractures. Proper patient selection and surgical experience are essential to achieving favorable outcomes. Studies with longer follow-up are required to assess potential late complications, such as the development of mucoceles. Full article

Objectives: The aim of this study was to evaluate the performance of GPT-4o in identifying nine common dental conditions on panoramic radiographs, both overall and at specific tooth sites, and to assess whether the use of different tooth numbering systems (FDI and Universal) in prompts would affect its diagnostic accuracy. Methods: Fifty panoramic radiographs exhibiting various common dental conditions including missing teeth, impacted teeth, caries, endodontically treated teeth, teeth with restorations, periapical lesions, periodontal bone loss, tooth fractures, cracks, retained roots, dental implants, osteolytic lesions, and osteosclerosis were included. Each image was evaluated twice by GPT-4o in May 2025, using structured prompts based on either the FDI or Universal tooth numbering system, to identify the presence of these conditions at specific tooth sites or regions. GPT-4o responses were compared to a consensus reference standard established by an oral-maxillofacial radiology team. GPT-4o’s performance was evaluated using balanced accuracy, sensitivity, specificity, and F1 score both at the patient and tooth levels. Results: A total of 100 GPT-4o responses were generated. At the patient level, balanced accuracy ranged from 46.25% to 98.83% (FDI) and 49.75% to 92.86% (Universal), with the highest accuracies for dental implants (92.86–98.83%). F1-scores and sensitivities were highest for implants, missing, and impacted teeth, but zero for caries, periapical lesions, and fractures. Specificity was generally high across conditions. Notable discrepancies were observed between patient- and tooth-level performance, especially for implants and restorations. GPT-4o’s performance was similar between using the two numbering systems. Conclusions: GPT-4o demonstrated superior performance in detecting dental implants and treated or restored teeth but inferior performance for caries, periapical lesions, and fractures. Diagnostic accuracy was higher at the patient level than at the tooth level, with similar performances for both numbering systems. Future studies with larger, more diverse datasets and multiple models are needed. Full article

Objectives: The increasing popularity of electric scooters (E-scooters) has led to a rise in trauma-related injuries, particularly in the craniofacial region. This study aims to compare dentoalveolar trauma (DT) patterns between E-scooter and bicycle accidents in a German urban area to identify differences in injury characteristics, risk factors, and treatment approaches. Materials and Methods: This retrospective study analyzed 178 patients treated for DT following E-scooter (n = 56) or bicycle (n = 122) accidents between January 2022 and December 2022 at a single oral and maxillofacial surgery department in a German urban area. Demographic, clinical, temporal, and therapeutic data were collected and statistically compared. Results: E-scooter patients were significantly younger (mean age: 33.6 vs. 47.0 years, p < 0.001) and predominantly female (85.7% vs. 26.2%, p < 0.001) compared to bicycle patients. E-scooter accidents more frequently occurred at night (69.6%) and on weekends (62.5%) and were significantly associated with alcohol consumption (55.4%) and low helmet use (8.9%). Clinically, E-scooter accidents resulted in more complex dental injuries, including a higher incidence of root fractures (14.3% vs. 0%, p < 0.001), complicated crown fractures (25.0% vs. 9.0%, p = 0.004), and crown-root fractures (32.1% vs. 9.8%, p < 0.001). Mandibular injuries were more prevalent in the E-scooter group, and concomitant facial fractures (excluding alveolar) were also more common (28.6% vs. 19.7%, p = 0.018). Conclusion: E-scooter accidents are associated with a distinct DT pattern involving younger, often alcohol-intoxicated, and helmetless patients, typically presenting with more severe and complex DT-injuries. These findings highlight the urgent need for targeted prevention strategies, legislative measures on helmet use, and clinician awareness of specific trauma profiles linked to E-scooter use.

Alcohol Use Disorder (AUD) is common among patients with maxillofacial trauma. Conventional perioperative care recommends complete abstinence. However, abrupt cessation can lead to Alcohol Withdrawal Syndrome (AWS), negatively impacting psychological well-being and compliance. This randomized controlled pilot study evaluated the effectiveness of Monitored Therapeutic Alcohol Administration (MTAA) in reducing perioperative stress and enhancing quality of life without impairing fracture healing. Twenty-four adult male patients with AUD and isolated facial fractures requiring surgery were enrolled. They were assigned to either an intervention group (n = 12) receiving MTAA—oral alcohol at 0.5 g/kg/day for two weeks—or a control group (n = 12) undergoing complete abstinence. Outcomes were assessed over six weeks, including stress (Zung Self-Rating Depression Scale), quality of life (Oral Health Impact Profile-14), soft tissue healing (Landry’s Index), and hard tissue healing (Moed’s Scale, serum osteocalcin). The MTAA group showed significantly reduced stress and improved quality of life (p < 0.001). Healing outcomes were comparable between groups, with no significant differences in soft tissue indices, osteocalcin levels, or radiographic scores. MTAA appears to be a safe and effective strategy to manage AWS-related distress and improve postoperative recovery, offering a practical alternative to strict abstinence in the surgical management of patients with AUD.

Background: Bicycles constitute a primary means of transportation, particularly within the scope of urban micromobility. However, the use of this mode of transport is associated with the risk of traffic accidents and subsequent maxillofacial trauma. Cyclists are classified as vulnerable road users, among whom the assessment of injury patterns is a significant issue. This study aimed to identify the most common maxillofacial fractures resulting from bicycle-related traffic accidents. Methods: A retrospective analysis was conducted on the medical records of patients treated at the Clinic of Maxillofacial Surgery at the University Clinical Hospital in Poznan, who sustained maxillofacial injuries as a result of bicycle-related accidents between 2019 and 2023. Results: A total of 99 patients met the inclusion criteria. Most of the study population was males (70.7%), with a median age of 38. Accidents most frequently occurred during the summer months and on Fridays and weekends. The most common fracture site was the mandible (40.4%), with double fractures being the predominant type. Additionally, zygomatic-orbital fractures were frequently observed (30.3%). In terms of treatment, surgical intervention was predominant, and the mean duration of hospitalisation was 6 days. Only 5.1% of patients were under the influence of alcohol at the time of the incident. Furthermore, it was found that isolated mandibular fractures occurred more frequently in younger patients, whereas midface fractures of the Le Fort II and III types were more commonly observed in individuals under the influence of alcohol at the time of the event. Moreover, accidents involving alcohol consumption were associated with a higher incidence of concomitant cranio-cerebral injuries. Conclusions: Defining the profile of maxillofacial fractures resulting from bicycle accidents constitutes a clinically relevant issue. Additionally, identifying the main risk factors and developing preventive measures is of critical importance. Full article

Background and Objectives: Interpersonal violence (IPV) has overtaken road traffic collisions as a leading cause of facial fractures, yet regional data from Southern Europe are limited. Materials and Methods: We retrospectively reviewed all adults (≥18 y) treated between 1 January 2011 and 31 December 2022 for radiologically confirmed IPV-related facial fractures. Recorded variables were demographics, AO-CMF (Arbeitsgemeinschaft für Osteosynthesefragen—Craniomaxillofacial) fracture site, Facial Injury Severity Score (FISS), presence of facial soft-tissue wounds, treatment modality, and length of stay; associations between variables were explored. Results: A total of 224 victims were identified; 94% were men (median age 26 y, IQR 22–34). The mandible was the most frequently involved bone (42%), followed by the orbit (25%); 14% sustained fractures at multiple sites. Facial soft-tissue wounds occurred in 9% of cases, three-quarters of which were associated with mandibular injury (p = 0.005). The median FISS was 2 and was higher in males, patients > 34 y, those with multiple fractures, and those with wounds (all p < 0.05). FISS showed a weak positive correlation with hospital stay (r = 0.23), which averaged 4.1 ± 1.6 days. Open reduction and internal fixation were required in 78% of patients, most often 24–72 h after admission. Annual IPV-related admissions remained stable throughout the 12-year period. Conclusions: IPV in this region consistently injures young men, with the mandible and orbit most at risk. FISS is a practical bedside indicator of resource use. The unchanging incidence—likely underestimated because isolated nasal fractures and minor injuries are often managed outside maxillofacial services or never reported—highlights the urgency of targeted prevention programs, routine screening, and streamlined multidisciplinary pathways.

Background: Midfacial fractures are common outcomes of facial trauma. While younger individuals typically sustain these injuries through high-energy events like assaults and traffic or sports accidents, elderly patients increasingly present with fractures from low-energy mechanisms, primarily falls. Purpose: The aim of this study was to analyze age- and gender-specific patterns in midfacial fractures over a 10-year period, with emphasis on elderly individuals and low-energy trauma. Methods: A retrospective review was performed of proven midfacial fractures between 2013 and 2022 at the Department of Oral and Maxillofacial Surgery (University of Pécs, Hungary). The patients were stratified by age (<65 vs. ≥65 years) and gender. The variables included the injury mechanism, fracture localization, the dental status, hospitalization, and the presence of associated injuries. Bivariate analyses were performed, and the significance level was set to p < 0.05. Results: A total of 957 radiologically confirmed midfacial fracture cases were evaluated, of whom 344 (35.9%) were ≥65 years old. In the elderly group, females had a 19-fold higher risk for midfacial trauma than younger females (OR: 19.1, 95%CI: 9.30–39.21). In the older group, a fall was significantly the most frequent injury mechanism (OR: 14.5; 95%CI: 9.9–21.3), responsible for 89.5% of the cases, while hospitalization (OR: 0.36; 95%CI: 0.23–0.56) was less characteristic. Most of the fractures occurred in the zygomatic bone, in the zygomaticomaxillary complex, or in the anterior wall of the maxilla. Associated injuries in the elderly group included mostly lower limb injuries—particularly pertrochanteric femoral fractures in females—and upper limb injuries, with a slight male dominance. Conclusions: Low-energy falls are the primary cause of midfacial fractures in elderly patients, particularly in women. Tailored prevention and management strategies are essential for improving the outcomes in this growing demographic group. Full article

Background: Foreign bodies (FBs) within the masticatory space are a rare but significant complication of oral and maxillofacial procedures. Despite advancements in orthognathic surgery, instrument breakage and accidental loss can lead to challenging secondary procedures. Clinical experience with retained foreign bodies in the masticatory space following orthognathic surgery and related dental procedures is summarized. Methods: A retrospective search was conducted in the surgical and radiological database of a tertiary referral center for maxillofacial surgery, covering procedures from January 2017 to December 2024. Patients were included if they had undergone orthognathic surgery and presented with a retained FB in the masticatory space confirmed through imaging. Clinical records, operative notes, imaging studies, and follow-up data were reviewed. Results: Out of 2092 procedures, four patients (0.19%) were identified. Two FBs were related to broken surgical instruments during orthognathic surgery (a suture needle and a burr fragment), while two were fractured local anesthesia needles during third molar extraction under local anesthesia. All FBs were located in deep compartments of the masticatory space (paramandibular or pterygopalatine region). Surgical retrieval via transoral approach under general anesthesia was successful in all cases. One patient experienced transient facial nerve dyskinesia; no long-term complications or recurrences were noted. Conclusions: Retained foreign bodies in the masticatory space are infrequent yet warrant prompt recognition and surgical management to mitigate the risk of infection, nerve damage, and repeated procedures. Thorough instrument checks, proper technique, and advanced imaging modalities are crucial for minimizing these complications in orthognathic surgery. Full article

Background: Facial trauma is one of the few surgical conditions that is routinely managed by three distinct disciplines, including Oral and Maxillofacial Surgery (OMS), Plastic and Reconstructive Surgery (PRS), and Otolaryngology (ENT). This study aims to evaluate mandibular trauma management strategies and clinical outcomes among three operating services. Methods: An IRB-approved, retrospective chart review was performed over a ten-year period (2007–2016) at a major, urban, Level I trauma center for all patients treated for an isolated mandibular injury determined by ICD-9 codes. Of the 2299 patients evaluated for traumatic facial injuries, 191 met the inclusion criteria and 137 had longitudinal data. Patient, fracture, and management characteristics and clinical outcomes were compared among three surgical services. Results: Most patients were male (95.3%), and assaults were the most common etiology of injury (79.1%). The angle/ramus was the most common single location (31.4%), and 47.6% of patients had multiple fractures. There was a statistically significant difference between specialties when assessing the use of operative versus non-operative approaches to fracture management (p < 0.001), and within operative management, for the use of open reduction-internal fixation (ORIF) alone versus ORIF with maxillomandibular fixation (MMF) (p = 0.002). There was no significant difference in the overall complications between specialties (p = 0.227). Conclusions: Services differ in their decision to pursue operative versus non-operative management, as well as the decision for postoperative MMF, though these differences in decision-making were not associated with a significant difference in the overall complications.

Background/Objectives: Orbital fractures are common facial injuries that require precise reconstruction to restore both function and esthetics. Heterologous cortical lamina and titanium preformed meshes are widely used for orbital wall reconstruction; however, comparative data on their outcomes remain limited. Methods: This retrospective observational study analyzed 67 patients treated for orbital fractures at Santa Maria Hospital, Terni, between January 2021 and November 2024. Patients underwent orbital reconstruction using either a heterologous cortical lamina or titanium mesh. Clinical data, including demographics, trauma etiology, fracture characteristics, surgical approach, and postoperative complications were collected. Outcomes such as diplopia, enophthalmos, ocular motility, and sensory impairment were assessed preoperatively and postoperatively and compared between groups. Statistical analyses included Chi-square and Mann–Whitney U tests, with logistic regression to identify risk factors for complications. Results: Accidental falls were the leading cause of injury (46.3%), with the orbital floor being the most commonly affected site (83.6%). Postoperative complications occurred in 15% of patients, with diplopia significantly reduced from 47.8% preoperatively to 10.4% postoperatively (p < 0.05). Sensory impairment and motility restrictions also improved significantly. Patients reconstructed using heterologous cortical lamina experienced significantly fewer postoperative complications compared to those treated with titanium mesh (OR = 0.171, 95% CI: 0.023–0.799, p = 0.040). Conclusions: Both heterologous cortical lamina and titanium mesh provide effective orbital reconstruction; however, the heterologous cortical lamina was associated with fewer postoperative complications, particularly diplopia and sensory impairment. Material selection should consider the fracture complexity, patient characteristics, and potential long-term outcomes. Full article

Background: AI has been adopted in dentistry for diagnosis, decision making, and therapy prognosis prediction. This systematic review aimed to identify AI models in dentistry, assess their performance, identify their shortcomings, and discuss their potential for adoption and integration in dental practice in the future. Methodology: The sources of the papers were the following electronic databases: PubMed, Scopus, and Cochrane Library. A total of 20 out of 947 needed further studies, and this was encompassed in the present meta-analysis. It identified diagnostic accuracy, predictive performance, and potential biases. Results: AI models demonstrated an overall diagnostic accuracy of 82%, primarily leveraging artificial neural networks (ANNs) and convolutional neural networks (CNNs). These models have significantly improved the diagnostic precision for dental caries compared with traditional methods. Moreover, they have shown potential in detecting and managing conditions such as bone loss, malignant lesions, vertical root fractures, apical lesions, salivary gland disorders, and maxillofacial cysts, as well as in performing orthodontic assessments. However, the integration of AI systems into dentistry poses challenges, including potential data biases, cost implications, technical requirements, and ethical concerns such as patient data security and informed consent. AI models may also underperform when faced with limited or skewed datasets, thus underscoring the importance of robust training and validation procedures. Conclusions: AI has the potential to revolutionize dentistry by significantly improving diagnostic accuracy and treatment planning. However, before integrating this tool into clinical practice, a critical assessment of its advantages, disadvantages, and utility or ethical issues must be established. Future studies should aim to eradicate existing barriers and enhance the model’s ease of understanding and challenges regarding expense and data protection, to ensure the effective utilization of AI in dental healthcare.

In Maxillofacial Reconstruction Applications (MRA), nonunion is one of the critical complications after the reconstruction process and fracture treatment, including bone grafts and vascularized flap. Nonunion describes the failure of a fractured bone to heal and mend after an extended period. Different systems and methods have been developed to monitor bone regeneration and fracture healing during and after the treatment. However, the developed systems have limitations and are yet to be used in MRA. The proposed smart reconstruction plate is a microdevice that could be used in MRA for wireless monitoring of fracture healing by measuring the forces applied to the reconstruction plate. The device is wireless and can transmit the acquired data to a human–machine interface or an application. The designed system is small and suitable for use in MRA. The results of finite element analysis, as well as experimental verification, showed the functionality of the proposed system in measuring small changes on the surface strain of the reconstruction plate and determining the corresponding load. By using the proposed system, continuous monitoring of bone regeneration and fracture healing in oral and maxillofacial areas is possible. Full article

Background/Objectives: Orbital fractures are a very serious problem due to the close location of the eyeball and a direct path to brain injuries, which is associated with serious consequences. This study aims to assess the usefulness of the Orbital Destruction Intensity (ODI) scale. Additionally, this article includes elements of an epidemiological study. Methods: A retrospective study of 160 patients admitted to the Department of Maxillofacial Surgery in Łódź (Poland) between January 2021 and June 2024 was conducted. In this study, general patient information (gender, age), details about the injuries (cause, affected orbit, accompanying symptoms), diagnosis (ODI scale, pathological classification), and treatment were assessed. Analysis of the distribution of features and regression analysis was performed in the case of quantitative data. To compare the assessment of the impact of a categorical variable on a quantitative variable, the Kruskal–Wallis test was used. A p-value of less than 0.05 was considered statistically significant. Results: The main cause of the accident was assault, which accounted for 39% of cases. An X-ray examination showed that patients had an average ODI score of 2.92 ± 1.69. Patients with low ODI scores mostly had isolated fractures of the orbital floor. As ODI scores increased, zygomaticomaxillary complex (ZMCO) fractures became more common as an additional fracture (p < 0.05). For patients with low ODI scores, treatment generally involves reconstructing the orbital wall with titanium mesh. For those with higher ODI scores, treatment may include microplate osteosynthesis or a combination of both methods (p < 0.05). Conclusions: A correlation was observed between the diagnosis based on ODI, anatomical classification, and the treatment provided. This relationship is related to the nature of the ODI scale, as, when the severity of the injury increases, additional anatomical structures (walls or rims of the orbit) are included. Full article

Background and Objectives: This study aimed to assess the frequency and distribution of facial bone injuries in terms of age, sex, residence, location, and etiology in the north-eastern region of Romania. Materials and Methods: This retrospective study was conducted within the Oral and Maxillofacial Clinics of “Sf. Spiridon” Hospital, Iași. The study group included 701 subjects (mean age 41.02 ± 18.45; sex: 603 males and 98 females) who were diagnosed with an orbital wall disorder. The epidemiological data on orbital wall fractures—including sociodemographic features, etiology, and location—were statistically analyzed. Results: The prevalence of orbital pathology was 1.47% congenital cases, 1.75% tumors, and 96.7% orbital fractures. The distribution of sex, age group, residence, and orbital localization varied significantly among the three diagnostic categories: tumors, congenital conditions, and fractures. Regarding sex, fractures were significantly more frequent in males (87.0%) compared to congenital cases (70.0%) and tumors (41.7%), while tumors showed a female predominance (58.3%) (p < 0.001). Congenital conditions predominantly affected patients under 20 years old (90.0%), whereas fractures were more evenly distributed across age groups, with higher frequencies between 31 and 50 years. In contrast, tumors involving the orbital walls were more frequent in older patients, with 33.3% in the 61–70 age group and 25.0% over 70 years. Regarding orbital localization, fractures were more likely to be bilateral (37.3%) or on the right side (44.3%), whereas congenital orbital defects and orbital tumors were predominantly unilateral and left-sided (70.0% and 66.7%, respectively). Bilateral involvement was rare in congenital cases (10.0%) and absent in tumors. Conclusions: The data support the finding that men are significantly more prone to trauma and orbital fractures, especially as a result of interpersonal violence and accidents, highlighting the need for preventive measures tailored to sex and socio-professional context.
