Characteristics and Injury Patterns in Traumatic Brain Injury Related to E-Scooter Use in Riga, Latvia: Multicenter Case Series.

Background and Objectives: In recent years, electronic scooters (e-scooters) have gained popularity, whether for private use or as a publicly available transportation method. With the introduction of these vehicles, reports of e-scooter-related accidents have surged, sparking public debate and concern. The aim of this study was to analyze the epidemiological data, characteristics, and severity of traumatic brain injury (TBI) related to e-scooter accidents. Materials and Methods: This retrospective case series evaluated patients who were admitted to the three largest neurosurgery clinics in Riga, Latvia, from the time period of April to October in two separate years-2022 and 2023-after e-scooter-related accidents. The data were collected on patient demographics, the time of the accident, alcohol consumption, helmet use, the type of TBI, other related injuries, and the treatment and assessment at discharge. Results: A total of 28 patients were admitted with TBI related to e-scooter use, with a median age of 30 years (Q1-Q3, 20.25-37.25), four individuals under the age of 18, and the majority (64%) being male. In 23 cases, the injury mechanism was falling, in 5 cases, collision. None were wearing a helmet at the time of the injury. Alcohol intoxication was evident in over half of the patients (51.5%), with severe intoxication (>1.2 g/L) in 75% of cases among them. Neurological symptoms upon admission were noted in 50% of cases. All patients had intracranial trauma: 50% had brain contusions, 43% traumatic subdural hematoma, and almost 30% epidural hematoma. Craniofacial fractures were evident in 71% of cases, and there were fractures in other parts of body in three patients. Six patients required emergency neurosurgical intervention. Neurological complications were noted in two patients; one patient died. Conclusions: e-scooter-related accidents result in a significant number of brain and other associated injuries, with notable frequency linked to alcohol influence and a lack of helmet use. Prevention campaigns to raise the awareness of potential risks and the implementation of more strict regulations should be conducted.

Minimally invasive keyhole supraorbital craniotomy as treatment option for penetrating foreign body through orbital roof.

Intraorbital foreign body is a rare condition, especially when extending into the intracranial compartment. When facing this scenario in the ER, the neurosurgeon must carefully choose the optimal point of surgical access in order to reduce morbidity. The authors hereby report the case of a 66 year-old male with a penetrating trauma to the orbit reaching the anterior cranial base through the orbital roof and associated with an intracerebral hematoma. The removal of the foreign body was performed by a dual approach: an 'eyebrow' supraorbital keyhole craniotomy and an intra-orbital extra-ocular exploration, with later microsurgical drainage of the hematoma and evisceration of the eye 48 hours later. The patient developed a pseudomeningocele, which was treated with lumbar puncture and compressive dressing. After proper intravenous antibiotic prophylaxis, the patient was discharged 21 days after hospital admission.

Craniofacial injuries related to motorized scooter use: A rising epidemic.

OBJECTIVES: Over the last decade, there has been increased interest in utilizing motorized scooters for transportation. The limited regulation of this modernized vehicle raises numerous safety concerns. This analysis examines a national database to describe the yearly incidence of craniofacial injuries and patterns of injury related to motorized scooter use. METHODS: The Consumer Product Safety Commission's National Electronic Injury Surveillance system was queried for craniofacial injuries associated with motorized scooter use. Patient demographics, injury type, anatomic location, injury pattern, and helmet status were extracted for analysis. RESULTS: From 2008 to 2017, there were 990 recorded events for craniofacial injuries secondary to motorized scooters extrapolating to an estimated 32,001 emergency department (ED) visits. The annual incidence was noted to triple over that 10-year period. The majority of patients were male (62.1%) and the common age groups at presentation were young children 6-12 years old (33.3%), adolescents 13-18 years old (16.1%) and young adults 19-40 years old (18.0%). The most common injury pattern was a closed head injury (36.1%) followed by lacerations (20.5%). Facial fractures were only present in 5.2% of cases. In cases in which helmet use was recorded, 66% of the patients were not helmeted. CONCLUSION: The incidence of motorized scooter related craniofacial trauma is rising, resulting in thousands of ED visits annually. Many patients are experiencing morbid traumatic injuries and may not be wearing appropriate protective equipment. This study highlights the importance of public awareness and policy to improve safety and primarily prevent craniofacial trauma.

Use of 3D printed models in student education of craniofacial traumas.

A low-cost 3D printed model has been introduced into the oral and maxillofacial surgery teaching program of undergraduate students to improve education and mechanical comprehension of craniofacial trauma. Steps of the 3D printed haptic model building process are listed. 3D printed models of facial fractures were obtained from Data Imaging and Communications in Medicine (DICOM) data. Computed Aided Design and Manufacturing (CAD-CAM) freeware was used to create new fractures on the standard tessellation language (STL) file. 3D printed haptic model appears to be an efficient low-cost support for craniofacial trauma education of undergraduate students.

A 32-year-old man with delayed onset post-traumatic proptosis and diplopia.

BACKGROUND: Proptosis and motility deficits are common findings in the setting of craniofacial trauma, but can indicate the presence of vision and even life-threatening pathology. OBJECTIVE: Our aim was to identify presentations consistent with traumatic carotid cavernous fistula (CCF) and to review the appropriate initial work-up and management. CASE REPORT: A 32-year-old man came to our emergency department with proptosis, ocular motility deficits, and decreased vision 1 month after a restrained motor vehicle accident. An orbital bruit was auscultated and four-vessel angiography revealed a CCF. Covered stents and an embolic agent were used to abolish the arteriovenous communication and the patient rapidly returned to his premorbid baseline. CONCLUSIONS: CCF is a relatively rare but important consequence of craniofacial trauma that must be recognized promptly in order to minimize the likelihood of serious sequelae. It should be suspected in patients with antecedent trauma presenting with exophthalmos, arterialized conjunctival vessels, and orbital bruit.

Correlation between Tomography Scan Findings and Clinical Presentation and Treatment Outcomes in Patients with Orbital Floor Fractures.

Background: Orbital floor fractures involve damage to the orbital floor but not the infraorbital margin. Despite intensive research, they remain a controversial topic. The aim of this study was to investigate the relationship between parameters gathered by means of computed tomography (CT), the clinical presentation, and treatment outcomes, in patients suffering from orbital floor fractures. Methods: Forty patients with orbital floor fractures were included in this study. Information regarding diplopia, impaired ocular mobility, asymmetric eyeball placement, and infraorbital paresis was gathered from the medical records. Nine CT-based parameters were assessed. Two parameters were calculated, based on them. The follow-up data of 30 patients were analyzed. The results were statistically evaluated. The significance level was p < 0.05. Results: Statistical evaluation revealed multiple correlations between CT-based findings, symptoms, and treatment results. Among others, the hernia into the maxillary sinus was significantly larger in patients without improvement in infraorbital paresis (p = 0.0031) and without improvement in assymetric eyeball placement (p = 0.0037). There was no correlation between the entrapment of the rectus inferior muscle and impaired ocular mobility (p = 0.664431; p = 0.420289) and between the direct fracture of the infraorbital canal and infraorbital paresis (p = 0.371102). Conclusions: The widely assumed thesis that impaired ocular mobility in orbital fractures is caused by entrapment of the rectus inferior muscle is disproved by CT-based data. CT-based findings, symptoms, and treatment results in patients with orbital floor fractures were significantly correlated. A large hernia may be a negative prognostic factor.

Successful reconstruction of severe traumatic scalp defect with exposed bones in a 6-year-old boy: a case report.

Full-thickness scalp defect reconstruction is considered challenging for the surgeon. The goal of this procedure is to provide coverage of the calvarium. Scalp defect needs thorough and careful planning in reconstruction, not only in choosing the best closure strategy but also in post-operative care. We report a case of successful reconstruction of traumatic severe scalp and bone loss using local scalp flap in a 6-year-old trauma patient. Free flap reconstruction should be considered in such a defect. However, limited resources prevented us to do so. In craniofacial trauma, the plastic surgeon may be involved as an attending physician in facial trauma or assisting in other trauma, especially in defect closure.

Non-perforated Traumatic Pneumoperitoneum in Maxillofacial Trauma: A Compelling Case Report.

Pneumoperitoneum typically results from intraabdominal gas due to gastrointestinal perforation, with exploratory laparotomy serving as the standard management. While non-surgical causes are well established, instances where pneumoperitoneum lacks an identifiable cause even after laparotomy are sparsely documented. Here, we present a case involving a 22-year-old male who, following a high-velocity road traffic injury resulting in a panfacial fracture, exhibited gross subcutaneous emphysema in the neck, pneumomediastinum, and pneumoperitoneum. This report aims to contribute to the growing understanding of such cases, potentially leading to the development of a management protocol that may help avoid unnecessary laparotomies in similar scenarios.

Assessment of Early and Late Management of Submental Gunshot Wounds.

Background: Management of submental gunshot wounds is becoming more common and requires complex surgical decisions. Objective: Compare outcomes of early and definitive reconstructive techniques following submental gunshot wounds. Methods: Retrospective chart review evaluated subjects who sustained a self-inflicted submental gunshot. The incidence of complications requiring unplanned operations was compared for early management techniques of skin/soft tissue, bone, and mucosal lining and definitive reconstructive techniques using Fisher's or Pearson Chi-square exact test with p ≤ 0.05 considered statistically significant. Results: The total of 27 patients were included. Early techniques included skin = primary soft tissue closure (n = 19) versus wound vacuum-assisted closure (n = 8); mandible = open reduction internal fixation (ORIF) (n = 19) versus external fixation (n = 8); and oral mucosal lining = primary mucosal closure (n = 20) versus dermal substitute (n = 7). Definitive management included ORIF (n = 10, 37%), ORIF with bone grafting (n = 8, 30%), and microvascular free-flap (n = 9, 33%). The incidence of complications requiring unplanned operation when using dermal substitutes for mucosal lining management was statistically higher than primary closure (p < 0.001); otherwise the complication rates of surgical techniques were equivalent. Conclusion: Several surgical decisions and techniques can be utilized at the time of early and definitive management of submental gunshot wounds. Only the use of dermal substitutes for mucosal lining is associated with a significantly higher rate of unplanned operation.

Prognostic indicators for feline craniofacial trauma: a retrospective study of 114 cases.

Craniofacial traumatic injuries contribute significantly to the morbidity and mortality of domestic felines. Previous studies focused on feline craniofacial injuries have investigated the origin of injury, injuries sustained, and effectiveness of diagnostic tools. The aim of the study is to identify prognostic indicators for feline craniofacial trauma patients and determine their association with negative and positive outcomes. The Veterinary Committee on Trauma (VetCOT) Trauma Registry and Dentistry and Oral Surgery Case Logs were utilized to identify feline craniofacial trauma cases that were presented to Colorado State University's Veterinary Teaching Hospital between 2014 and 2020. Prognostic indicators evaluated included: etiology of injury, signalment (age and sex), the Modified Glascow Coma Scale (MGCS), Animal Trauma Triage (ATT) scores, craniofacial examination findings, diagnostic imaging technique, and injuries identified via imaging. Outcomes were determined via patient status upon discharge. Outcomes were grouped into the following categories: survival to discharge at initial presentation to CSU Urgent Care (SDIP), survival to discharge after injury treatment/repair by CSU DOSS or another specialty service (SDTX), euthanized due to grave prognosis at initial presentation (EUGP), euthanized due to financial limitations at initial presentation (EUF), and euthanized due to grave prognosis and financial limitations (EUGP + EUF). The continuous data was described using means and standard deviations. To determine the associations of various groupings of clinical signs and imaging findings with outcome a principal component analysis was performed. Patient sex, trauma etiology, cumulative MGCS and ATT scores on initial presentation and clinical signs on initial presentation were identified as prognostic indicators with intact males, vehicular and animal altercations, lower MGCS cumulative scores, higher ATT scores and the presence of altered mentation identified as negative prognostic indicators. Prognostic indicators for feline craniofacial trauma can be associated with outcomes and help guide clinical decision making.

Patterns and Trends of Facial Fractures at a Tertiary Care Trauma Center in India - A 13 years Retrospective Study.

Study Design: Retrospective study. Objective: The purpose of this study was to retrospectively analyze the prevalence, pattern, diagnosis, and treatment of the facial fractures falling under ambit of facial plastic surgery in a multi-specialty hospital at India from the year 2006-2019. Methods: This retrospective study analyzed 1508 patients, having orbital fractures (from 2006 to 2019) for demographic data, cause of trauma, type of fracture, and the treatment given. The data were compiled in excel and analyzed by using SPSS version 21.0. Results: Out of these 1508 patient (1127 (74.73%)-males and 381 (25.27%)-females), the etiology of injuries was Road traffic accident (RTA) (49.20%), assault (26.52%), and sports injuries (11.47%). The most common fracture pattern was Isolated Orbit and/or Orbital Floor fracture in 451 patients (32.08%), followed by Mid-facial fractures (21.93%). Also, 105 patients (6.96%) experienced ocular/retinal trauma along with other fractures. Conclusions: Orbit, peri-ocular, and mid-face trauma comprised a large position of this study. It requires a great deal of expertise to treat such complex trauma, which is not covered in one specialty alone. Hence, a holistic approach of craniofacial fracture management, rather than limiting these skills to water-tight craniofacial compartments becomes necessary. The study highlights the critical need of multidisciplinary approach for predictable and successful management of such complex cases.

Pediatric Nasal and Septal Fractures.

Pediatric nasal bone and septal fractures represent a large number of craniofacial injuries in children each year. Due to their differences in anatomy and potential for growth and development, the management of these injuries varies slightly from that of the adult population. As with most pediatric fractures, there is a bias toward less-invasive management to limit disruption to future growth. Often this includes closed reduction and splinting in the acute setting followed by open septorhinoplasty at skeletal maturity as needed. The overall goal of treatment is to restore the nose to its preinjury shape, structure, and function.

Management of Complications and Secondary Deformity After Fractures of the Midface, Orbit, and Upper Third of the Maxillofacial Skeleton.

Craniomaxillofacial trauma is a challenging entity to manage effectively and often necessitates serial evaluation and treatment. A multidisciplinary team is best served to evaluate and treat these complex injury patterns with the use of necessary adjuncts, such as neuronavigation, intraoperative imaging, custom implant use, and virtual surgical planning. Complications of facial trauma can present at a spectrum of time points and manifest in a variety of manners and as such patients should be observed closely and longitudinally. Although not all complications and secondary deformities can be avoided, this article highlights some common pitfalls and our unique management strategies.

Pediatric Cranial Vault and Skull Base Fractures.

Cranial vault and skull base fractures in children are distinctly different from those seen in adults. Pediatric skull fractures have the benefit of greater capacity to remodel; however, the developing pediatric brain and craniofacial skeleton present unique challenges to diagnosis, natural history, and management. This article discusses the role of surgical treatment of these fractures, its indications, and techniques.

Power Drill Craniostomy for Bedside Intracranial Access in Traumatic Brain Injury Patients.

Invasive neuromonitoring is a bedrock procedure in neurosurgery and neurocritical care. Intracranial hypertension is a recognized emergency that can potentially lead to herniation, ischemia, and neurological decline. Over 50,000 external ventricular drains (EVDs) are performed in the United States annually for traumatic brain injuries (TBI), tumors, cerebrovascular hemorrhaging, and other causes. The technical challenge of a bedside ventriculostomy and/or parenchymal monitor placement may be increased by complex craniofacial trauma or brain swelling, which will decrease the tolerance of brain parenchyma to applied procedural force during a craniostomy. Herein, we report on the implementation and safety of a disposable power drill for bedside neurosurgical practices compared with the manual twist drill that is the current gold standard. Mechanical testing of the drill's stop extension (n = 8) was conducted through a calibrated tensile tester, simulating an axial plunging of 22.68 kilogram (kg) or 50 pounds of force (lbf) and measuring the strength-responsive displacement. The mean displacement following compression was 0.18 ± 0.11 mm (range of 0.03 mm to 0.34 mm). An overall cost analysis was calculated based on the annual institutional pricing, with an estimated $64.90 per unit increase in the cost of the disposable electric drill. Power drill craniostomies were utilized in a total of 34 adult patients, with a median Glasgow Coma Scale (GCS) score of six. Twenty-seven patients were male, with a mean age of 50.7 years old. The two most common injury mechanisms were falls and motor vehicle/motorcycle accidents. EVDs were placed in all subjects, and additional quad-lumen neuromonitoring was applied to 23 patients, with no incidents of plunging events or malfunctions. One patient developed an intracranial infection and another had intraparenchymal tract hemorrhaging. Two illustrative TBI cases with concomitant craniofacial trauma were provided. The disposable power drill was successfully implemented as an option for bedside ventriculostomies and had an acceptable safety profile.

Applications of Preoperative and Intraoperative Technologies for Complex Primary and Secondary Facial Trauma Reconstruction.

This article provides a review of the current technologies available in the preoperative and intraoperative management of complex and secondary maxillofacial trauma reconstruction. These patients present a unique challenge for which the advancement of imaging technologies, patient-specific modeling and implants, and intraoperative imaging and navigation can play an important role to improve their post-treatment outcomes.

Systematic review and meta-analysis of arterial embolization compared with traditional management on outcomes of traumatic massive facial haemorrhage.

BACKGROUND: Maxillofacial trauma accounts for ~10% of trauma presentations to most centres, with massive haemorrhage occurring in 1.2-4.5% of cases. Despite its infrequent presentation, there is significant associated morbidity and mortality. Transcatheter arterial embolization (TAE) is playing an increasingly prominent role in trauma presentations. The aim of this article was to compare outcomes of TAE with more traditional management methods for the treatment of massive facial haemorrhage following maxillofacial trauma. METHODS: A database and Google Scholar search was performed, with articles discussing massive facial haemorrhage secondary to maxillofacial trauma and its management included. RESULTS: Twenty-seven articles were found that met inclusion criteria, encompassing 384 patients. Statistical testing comparing mortality between TAE and non-TAE groups did not find a significant difference, with a mortality rate of 30.2% in the TAE group and 38.9% in the non-TAE group. Assessment of morbidity directly related to interventions was difficult, as many of the included participants had significant associated injuries which contributed an indeterminate degree to morbidity. There was a 10% rate of adverse events associated with TAE, most commonly puncture site haematomas and soft tissue swelling, with more significant adverse events including cerebrovascular accidents and blindness. CONCLUSION: Embolization was correlated with increased rates of haemorrhage control when compared with other interventions. Overall, despite no significant impact on mortality, embolization is recommended in the management of massive haemorrhage following maxillofacial trauma due to improved success rates at haemorrhage control and a low rate of significant adverse events.

Traumatic carotid-cavernous fistula: A case report.

Direct carotid-cavernous fistulas are a rare complication of craniofacial trauma that often presents with proptosis, chemosis, and other visual symptoms. Disruption of blood flow from a carotid-cavernous fistula can cause cortical and cranial nerve ischemia which requires emergent intervention. Upon clinical suspicion of a carotid-cavernous fistula, patients should undergo computed tomography angiography (CTA) or magnetic resonance angiography (MRA), and digital subtraction angiography (DSA) if no other etiology is suspected. We present a case of a middle-aged patient with a gunshot wound in the posterior pharynx that resulted in a direct carotid-cavernous fistula of the left internal carotid artery.

Massive recurrent epistaxis in traumatic pseudoaneurysm of sphenopalatine artery: Report of 2 cases.

Massive recurrent epistaxis because of traumatic pseudoaneurysm of the sphenopalatine artery is rarely diagnosed. It is formed by partial rupture of the endothelium by facial trauma and managed with embolization and maxillofacial reconstruction. Here, we report a case of 2 massive recurrent epistaxes and 1 case of carotid cavernous fistula, which needed embolization to control the recurrent bleeding following trauma. Epistaxis is first managed by tampon, then referred as needed for endovascular intervention by sphenopalatine artery embolization and followed by maxillofacial reconstruction. Recurrent epistaxis was successfully treated with endovascular embolization.

Slippery Slopes: Skiing-Related Facial Trauma in Adults.

Study Design: Retrospective, observational, cross-sectional study. Objective: To determine the incidence of skiing-related facial trauma and to identify their patterns in terms of potential risk factors, mechanism of injury, anatomical location, and degree of severity. Methods: Data was collected using the National Electronic Injury Surveillance System and included snow skiing-related incidents during the years 2009 to 2018. Specifically, injuries limited to the facial region including the head, face, eye(s), mouth, neck or ear(s) were reported. Patients with fractures were further classified by the study variables. Descriptive statistics were used to classify continuous variables while chi-square analysis was used to compare categorical variables. Results: A total of 514 (n = 514) patients met the inclusion criteria within the study period. The majority of injuries were due to concussions (59%), followed by lacerations (18%), fractures (11%), contusions (11%) and dental injuries (1%). Of the fractures seen, the majority were nasal (30%) and cervical spine (30%), followed by midface (27%), mandible (9%) and skull (4%). In our population, head injuries were more common in females (80%) than in males (60%), whereas, mouth injuries were more common in males (8%) than females (1%) [χ2 = 30.2, p < 0.001]. Conclusions: Skiing-related craniofacial trauma remains a significant mechanism of injury. Our data illustrates a need to correlate these injuries to the use of personal protective equipment. Furthermore, this data calls for the strict implementation of such equipment and the development of safety protocols to further prevent deleterious injury.
