Background: Midfacial fractures are among the most frequent facial fractures. Surgery is recommended within 2 weeks of injury, but this time frame is often extended because the fracture is missed on diagnostic imaging in the busy emergency medicine setting. Using deep learning technology, which has progressed markedly in various fields, we attempted to develop a system for the automatic detection of midfacial fractures. The purpose of this study was to use this system to diagnose fractures accurately and rapidly, with the intention of benefiting both patients and emergency room physicians., Methods: One hundred computed tomography images that included midfacial fractures (e.g., maxillary, zygomatic, nasal, and orbital fractures) were prepared. In each axial image, the fracture area was surrounded by a rectangular region to create the annotation data. Eighty images were randomly classified as the training dataset (3736 slices) and 20 as the validation dataset (883 slices). Training and validation were performed using Single Shot MultiBox Detector (SSD) and version 8 of You Only Look Once (YOLOv8), which are object detection algorithms., Results: The performance indicators for SSD and YOLOv8 were respectively: precision, 0.872 and 0.871; recall, 0.823 and 0.775; F1 score, 0.846 and 0.82; average precision, 0.899 and 0.769., Conclusions: The use of deep learning techniques allowed the automatic detection of midfacial fractures with good accuracy and high speed. The system developed in this study is promising for automated detection of midfacial fractures and may provide a quick and accurate solution for emergency medical care and other settings., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Frontal bone fractures are amongst the most common facial fractures and surgical management, which has traditionally involved access via a coronal flap, can result in unsightly scarring, alopecia, paraesthesia, facial nerve weakness and temporal hollowing. Alternative approaches include use of endoscopically-assisted surgery, often through the eyebrow, which minimises the risk of unsightly scarring but may also sacrifice access in the process. In this technical note, we discuss a surgical technique for open reduction and internal fixation of fractures of the bone overlying the frontal sinus and supra-orbital rim, which the authors have not found in the literature, which involves the making of a "zig-zag" incision through the eyebrow in a trichophytic manner which reduces the risk of unsightly scarring whilst simultaneously allowing for sufficient surgical access to the fracture site., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Midface fractures present a clinical challenge in otorhinolaryngology due to their often complex injury pattern and nonspecific symptoms. Precise diagnostics, including differentiated imaging procedures, are required. Interdisciplinary consultation between otorhinolaryngology, maxillofacial surgery, neurosurgery, and ophthalmology is often necessary. When selecting radiographic modalities, radiation hygiene should be taken into account. Sonography provides a radiation-free imaging alternative for fractures of the nasal framework and anterior wall of the frontal sinus. The goal of treatment is to achieve stable and symmetrical reconstruction. Depending on the injury pattern, different osteosynthesis materials, individual access routes, and various surgical procedures can be used. In clinical practice, the management of midface fractures requires a multidisciplinary, flexible, and pragmatic approach based on the fracture pattern and clinical experience., (© 2024.

Background: Patients with traumatic brain injuries (TBIs) often experience concurrent facial bone fractures. In 2021, a prediction model with 10 variables was published and precisely predicted concomitant facial fractures in TBI patients. Herein, external validation and simplification of this model was performed., Methods: Traumatic brain injury patients treated at a major referral trauma center were retrospectively reviewed for 1 year. The original prediction model (published in 2021), which was developed from a rural level II trauma center, was applied for external validation. A new and simplified model from our level I trauma center was developed and backwardly validated by rural level II trauma center data., Results: In total, 313 TBI patients were enrolled; 101 (32.3%) had concomitant facial fractures. When the previous prediction model was applied to the validation cohort, it achieved acceptable discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.713 and good precision, with a Brier score of 0.083. A new and simplified model with 6 variables (age, tooth rupture, epistaxis, facial lesion, eye injury, and intracranial hemorrhage) was created with excellent discrimination (AUC = 0.836) and good precision (Brier score of 0.055). The backward validation of this new model also showed excellent discrimination in the cohort used to develop the original model (AUC = 0.875)., Conclusion: The original model provides an acceptable and reproducible prediction of concomitant facial fractures among TBI patients. A simplified model with fewer variables and the same accuracy could be applied in the emergency department and at higher- and lower-level trauma centers., Competing Interests: Conflicts of interest and sources of funding: No commercial associations with or sources of support from any funding agency., (Copyright © 2024 Wolters Kluwer Health, Inc.

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., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Pediatric panfacial trauma is a rare occurrence with poorly understood implications for the growing child. Treatment algorithms largely mirror adult panfacial protocols with notable exceptions including augmented healing and remodeling capacities that favor nonoperative management, limited exposure to avoid disruption of osseous suture and synchondroses growth centers, and creative fracture fixation techniques in the setting of an immature craniomaxillofacial skeleton. The following article provides a review of our institutional philosophy in the management of these challenges injuries with important anatomic, epidemiologic, examination, sequencing, and postoperative considerations., (Copyright © 2023 Elsevier Inc.

Background: The incidence and causes of facial fractures differ between patients, but patterns arise within populations. These patterns vary by gender, age, and between countries. This study aims to determine variables to identify patients at risk for facial fractures in a United States trauma population., Methods: This is a single-center study of Trauma Registry data, inclusive of years July 1, 2016, to January 31, 2022. Inclusion criteria were based upon all trauma patients. Confirmation of a non-isolated facial fracture (dependent variable) was verified using ICD10 diagnosis codes. A logistic regression was performed in SPSS to ascertain the effects of predictor variables on the likelihood that a trauma patient will experience a facial fracture., Results: 20377 patients were included in the analysis based upon the requirements specified in the methods section; 1575 (7%) had a positive facial fracture. The logistic regression model was statistically significant (N = 18507, P < .01). Significant risk factors for facial fracture identified included helicopter transport (OR = 1.35, P < .01) and increasing injury severity scores (OR = 1.07, P < .01). Modes of injury most likely to predict facial fracture included assault (OR = 6.62, P < .01), moped (OR = 2.02, P < .01), and motorcycle trauma (OR = 1.55, P < .01). The discharge disposition most likely among facial fracture patients included short-term general hospital (OR = 1.71, P < .01) and intermediate care facility (OR = 4.47, P < .01)., Conclusions: Patients with traumatic injuries from assault, moped, and motorcycle accidents were more likely to present with facial fractures. These patients had more severe injuries, seen as increased ISS scores, higher likelihood of transport by helicopter, and the need for additional care after discharge., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organizations that might have an interest in the submitted work.

Traumatic brain injuries (TBIs) associated with maxillofacial fractures (MFFs) are a public health concern worldwide, especially among adult-aged males. There is an urgent need for early detection of associated TBIs in patients with MFFs during the initial assessment and treatment stage to reduce morbidity and mortality. The objective of the present study was to systematically review the literature to determine specific MFF situations associated with TBIs and to identify the factors associated with TBIs in patients with MFFs. The protocol was developed in accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and was registered to the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42020155912. Overall, of 26,774 patients recorded, 13,667 patients (51.04%) sustained MFFs with an associated TBI. The male to female ratio was 4.8:1. RTA was the most common cause. The most common TBIs were concussions, contusions, and closed brain injuries. Within the limits of this study, it was concluded that TBI-related MFFs should be suspected whenever maxillary or mandibular bone fractures occur, especially among adults, males, and people with injuries caused by RTAs and assaults. There is a need to increase the awareness of maxillofacial surgeons on the possible associations of combined maxillofacial trauma and brain injuries., (© 2022.

Objective: Head trauma is the most common cause of death from child abuse, and each encounter for recurrent abuse is associated with greater morbidity. Isolated skull fractures (ISF) are often treated conservatively in the emergency department (ED). We determined patterns of physical abuse screening in a children's hospital ED for children with ISF., Methods: A retrospective review was performed for children aged 3 years and younger who presented to the ED with ISF from January 1, 2015 to December 31, 2019. Children were stratified by age (<12 mo, ≥12 mo) and witnessed versus unwitnessed injury. Primary outcome was social work (SW) assessment to prescreen for abuse. Secondary outcomes were suspicion for abuse based on Child Protective Services (CPS) referral and subsequent ED encounters within 1 year., Results: Sixty-six ISF patients were identified. Of unwitnessed injury patients aged younger than 12 months (n = 17/22), 88.2% (n = 15/17) underwent SW assessment and 47.1% (n = 8/17) required CPS referral. Of witnessed injury patients aged younger than 12 months (n = 23/44), 60.9% (n = 14/23) underwent SW assessment, with no CPS referrals. Overall, 18.2% (n = 4/22) unwitnessed and 20.5% (n = 9/44) witnessed injury patients returned to our ED: 2 were aged younger than 12 months and had recurrent trauma., Conclusions: To decrease risk of missed physical abuse, SW consultation should be considered for all ISF patients., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objectives: This study aimed to describe which infants with a skull fracture (1) receive a child abuse pediatrician (CAP) consultation, (2) receive a skeletal survey, and (3) re-present to medical care before age 3 years with concerns for physical abuse., Methods: We conducted a retrospective chart review of infants younger than 12 months who presented to the emergency department between January 1, 2005, and December 30, 2015, with a skull fracture. Medical records were reviewed for the skull fracture presentation and for all future medical evaluations at the same institution with concerns for physical abuse until 3 years of age., Results: Of 366 infants with a skull fracture, a CAP was contacted for 272 (74%) and 76 (20.8%) infants who received a skeletal survey. Factors associated with skeletal survey acquisition included younger age (<6 months), no history to explain the skull fracture, other injuries on examination, and social risk factors. Six children (1.6%) re-presented to medical care with concerns of physical abuse before age 3 years. Five of these infants did not have a skeletal survey at the time of their skull fracture, and 1 was likely a case of missed physical abuse at the time of the skull fracture., Discussion: Most skull fractures in infancy occur accidentally, and a skeletal survey may not be necessary for every infant. Obtaining a thorough history including social risk factors, performing a complete physical examination, and consulting with a CAP is an effective first step in the evaluation of physical abuse in infants with skull fractures., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: The present study comprises a retrospective analysis of skull, skull base, and midface fractures in children, to provide clinical orientation for their management. To date, only few data are available on these injuries in this patient group., Methods: Data from inpatient cases diagnosed with a midface, skull, or skull base fracture in the Children's Hospital Auf der Bult from 2015 to 2020 were evaluated. Age, gender, fracture mechanism, diagnosis, treatment, and possible complications were analyzed. Data of 224 children were grouped into 107 cases with nose fractures, 104 cases with skull fractures, 9 patients with temporal bone fractures, 4 patients with rhinobasal fractures, and 2 cases with fractures of the orbital floor., Results: Among patients with nose fractures, the average age was 10.9 years (64% males), among patients with skull fractures 1.0 year (64% males), and in children with skull base fractures 6.0 years (85% males). Falls were the most frequent genesis (63%), followed by car accidents, collisions (25%), and violence (10%). Patients with skull fractures underwent sonography in 94% of cases; in 87% the fracture was verified. Patients with nose fractures underwent x‑ray in 92% of cases, or sonography only in 8%; 95% of patients with nose fractures underwent operative repositioning. Typical fracture signs (i.e., hemotympanum, ophthalmic symptoms) or signs of central nervous system involvement (i.e., nausea, amnesia) occurred in 12 of 13 children with skull base fractures, and CT was performed in all these cases (none of whom developed a cerebrospinal fluid leak)., Conclusion: The imaging modality should be selected based on the clinically suspected diagnosis and the course. Most fractures can be sufficiently treated without any permanent sequelae, except for nose fractures, which frequently require operative repositioning., (© 2022.

Importance: Although nasal bones are the most common type of facial fracture given their natural projection and vulnerability to trauma, there is a paucity of data on its trends. Objective: To report on the trends and costs associated with open and closed nasal bone fractures across the United States. Methods: A retrospective analysis from 2006 to 2014 was conducted of the Nationwide Emergency Department Sample by using the International Classification of Disease, Ninth Revision codes for closed and open nasal bone fractures (802.0 and 802.1) presenting to emergency departments (ED). Trend analysis of total number and rate of visits, discharges, admissions, and associated costs were conducted. Results: Data from 1,253,399.741 records were collected. The total number of ED visits decreased by 2.05% for both open and closed nasal fractures from 2006 to 2014 whereas their associated costs increased ( p  < 0.001 and p  < 0.05 for closed and open nasal fractures). Notably, open fractures were consistently costlier whereas closed fractures had a greater percent-increase in costs (76.65%). Conclusions and Relevance: This study identified a significant rise in nasal fracture costs, which can be reduced via use of cheaper diagnostic modalities and cost-effective endoscopic procedures.

Mild traumatic brain injury (mTBI) and concussion, a subtype of mTBI, commonly present to the emergency department (ED) and may present with symptoms identical to those associated with more severe TBI. The development and use of clinical decision rules, increased awareness of the risk of radiation associated with head computed tomography, and the potential for patient observation has allowed emergency clinicians to make well-informed decisions regarding the need for imaging for patients who present with mTBI. For patients who present to the ED with concussion, appropriate diagnosis, management, and education are critical for optimal recovery. This issue reviews the most recent literature on concussion and mTBI and provides recommendations for the evaluation, diagnosis, and treatment of mTBI and concussion in the acute setting.

Orbitorrhea is defined as a leak of cerebrospinal fluid from a cranio-orbital fistula. It is usually related to anterior skull base trauma. Orbitorrhea is an exceptional and life-threatening condition which should be promptly managed. We herein report the case of a right post-traumatic orbitorrhea following anterior skull base trauma. Conservative treatment was initially attempted. At 6 weeks, recurrence was noted, and the patient underwent neurosurgical management. A few months later, a secondary upper lid retraction was diagnosed and treated by full-thickness skin graft with favourable outcome. To our knowledge, fewer than 30 cases have been previously reported. Ophthalmologists should be aware of this life-threatening condition which could be underestimated.

Purpose: The purpose of this study was to stratify fractures associated with child abuse in relation to the child's age., Methods: The Kids' Inpatient Database (1997-2012) was queried for all patients (<18 years old) with a diagnosis of fracture and child abuse. The primary outcome was age-related determinants of fracture distribution. Chi-squared analysis was used for statistical analysis where appropriate, with significance set at p < 0.05., Results: More than 39,000 children were admitted for child abuse, and 26% sustained fractures. Most were infants (median age 0 year [IQR 0-1]). 28% sustained multiple fractures, and 27% had skull fractures. By age, infants had the highest rate of multiple fractures (33% vs 16% 1-4 years), and the highest rate of closed skull fractures (33% vs 21% ages 1-4), while adolescents had more facial fractures (43% vs 11% ages 9-12), all p < 0.001. Multiple rib fractures were more commonly seen in infants (28% vs 8% ages 1-4), while children 5-8 years had the highest rates of clavicular fractures (7% vs 3% in infants), all p < 0.001., Conclusion: Age-related fracture patterns exist and may be due to changing mechanism of abuse as a child grows. These age-related fracture patterns can help aid in healthcare detection of child abuse in hopes to thwart further abuse., Type of Study: Retrospective comparative study., Level of Evidence: Level III., (Copyright © 2020 Elsevier Inc.

Background: Computed tomography of the head (CTH) and maxillofacial bones (CTMF) can be performed concurrently, but CTMF is frequently ordered separately, after facial fractures identified on CTH scans. This study aims to evaluate whether obtaining additional CTMF after CTH changes operative management of patients with facial trauma., Materials and Methods: A retrospective chart review was performed of all patients with facial trauma who presented to our level 1 trauma center between January 2009 and May 2019. CTH and CTMF were reviewed for each patient. Fracture numbers and patterns were compared to determine if CTMF provided additional information that necessitated change in management, based on predetermined criteria., Results: A total of 1215 patients were assessed for facial trauma. Of them, 899 patients underwent both CTH and CTMF scans. CTH identified 22.7% less fractures than CTMF (P < 0.001); specifically, more orbital, nasal, naso-orbito-ethmoid, zygoma, midface, and mandible fractures (P < 0.001). Of all patients 9.2% (n = 83) of patients with nonoperative fractures on CTH were reclassified as operative on CTMF; 0.6% (n = 5) with operative patterns on CTH were reclassified as nonoperative on CTMF, and 18.1% (n = 163) experienced a changed in their operative plan though operative fractures were seen on both imaging modalities. Additional findings seen on CTMF delegated change in the operative plan in 27.9% (n = 251) of cases., Conclusions: CTMF scans are necessary to determine operative intervention. As CTH and CTMF are constructed from the data, physicians should consider ordering both scans simultaneously for all patients with facial trauma to limit radiation exposure, control costs, and avoid delays in care., (Copyright © 2020 Elsevier Inc.

Growing skull fracture (GSF) is an uncommon post-traumatic complication, which accounts for approximately 0.05% to 1% of all skull fractures. Delayed diagnosis of GSF in adulthood is rare and often involved with a variety of neurological symptoms. Here, we reported an adult patient, with an interval of 17 years from initial head trauma to first diagnosis of GSF. The patient complained of short periods of fainting and bilateral visual hallucinations, with a hard palpable bulge around his right occipitomastoid suture region. Computed tomographic imaging demonstrated an arachnoid cyst extending into right mastoid cavity. Consequently, the delayed diagnosis of GSF was confirmed, and the patient was managed with duroplasty and cranioplasty. At the 8-month follow-up, the patient showed an uneventful postoperative recovery. A comprehensive literature review was also conducted, and a total of 70 GSF cases were identified and summarized. According to the literature review, patients with GSF generally have a history of head trauma in their childhood, and delayed diagnosis is a common situation. Diagnosis of GSF should include complete retrospective medical history, physical, and imaging examinations. Once the diagnosis is confirmed, cranioplasty accompanied with duroplasty might be the most effective way to relieve symptoms and prevent further damage.

Background: Nasal fractures constitute the largest proportion of facial trauma each year, however, there is no consensus management. In this study, we investingated the role of the consultant and the functional and aesthetic outcomes of procedures performed to address nasal bone fractures., Methods: A retrospective chart review of patients who sustained nasal bone fractures was conducted from 8/1/14 through 1/23/18. Categorical variables were analyzed using chi-squared testing and Fisher's exact test, where appropriate, while continuous variables were compared using Mann-Whitney U testing., Results: During the study period, 136 patients met inclusion criteria for full analysis. The mean age of this cohort was 47.6 ± 20.2 years with the majority identifying as African-American (53.7%) and male (67.2%). Otolaryngologists were significantly more likely to assess pre-operative nasal obstruction (100%) compared to plastic surgeons (24.1%) ( P  < .001). Otolaryngology elected operative management (53.3%) at a significantly higher rate than plastic surgery (24.1%) ( P  = .005). Additionally, otolaryngology was significantly more likely to manage patients in an outpatient setting (91.2%), whereas plastic surgery more commonly performed inpatient management (57.1%) ( P  = .006). Plastic surgery averaged a significantly shorter amount of time from presentation to operative management (7.3 ± 10.7 days) compared to otolaryngology (20 ± 27.7) ( P  = .019). Consulting service was not associated with a need for revision surgery., Conclusions: Consultants across subspecialties differ in the management of nasal bone trauma. A more standardized approach is warranted by all individuals involved in the care of maxillofacial trauma patients.

Infant skull fractures are common in both accidental and abusive head trauma, but identifying the cause of injury may be challenging without adequate evidence. To better understand the mechanics of infant skull fracture and identify environmental variables that lead to certain skull fracture patterns, we developed an innovative computational framework that utilizes linear elastic fracture mechanics theory to predict skull fracture as a first step to study this problem. The finite element method and adaptive-remeshing technique were employed to simulate high-fidelity, geometrically explicit crack propagation in an infant skull following impact. In the framework, three modes of stress intensity factors are calculated by means of the M-integral using the commercial analysis code, FRANC3D, and are used as measures of crack driving force. The anisotropy of infant skulls is represented by means of a transversely isotropic constitutive model and a direction-dependent fracture-toughness locus. The ability of the framework to predict impact-induced fracture patterns is validated by comparison with experimentally observed fracture patterns from the literature.

Importance: The nasal bone is one of the most commonly fractured bones of the midface. However, the frequency of coincident fractures of adjacent bones such as the frontal process of the maxillary bone, nasal septum, and medial or inferior orbital walls has not been fully evaluated. Objective: The purpose of this study was to investigate the incidence of fractures of adjacent structures in the setting of a nasal bone fracture. Second, we propose a new classification system of nasal bone fractures with involvement of adjacent bony structures. Design, Setting, and Participants: One thousand, one hundred ninety-three patients with midfacial fractures were retrospectively reviewed. The characteristics of fractures of the nasal bone and the incidence of coincident fractures of the frontal process of maxilla, bony nasal septum, medial, or inferior orbital walls were analyzed. Exposure: All patients included in the study presented with nasal trauma. Main Outcomes and Measures: The coincident fractures of adjacent midfacial structures were assessed, and a new classification of midfacial fractures based on computed tomography (CT) scan images was proposed. Results: Among the 1193 cases, bilateral fractures of the nasal bone were most common (69.24%), and coexistent fracture of the frontal process of the maxilla and bony nasal septum was 66.89% and 42.25%, respectively. Coincident fracture of the orbital walls was observed in 16.51% of cases. The major etiology of fracture for the younger and elderly groups was falls, compared with assault as the most common etiology in the adult group. A classification scheme was generated in which fractures of the nasal bone were divided into five types depending on coexisting fractures of adjacent structures. Conclusions and Relevance: External force applied to the nasal bone can also lead to coexistent fracture of adjacent bony structures including the frontal process of the maxilla, nasal septum, and orbital walls. The proposed classification of nasal fracture based on CT imaging helps to incorporate coincident disruption of adjacent structures.

Background: Currently, the pathogenesis of leptomeningeal cysts, also known as growing skull fractures, is still debated. The purpose of this study was to examine the specific skull fracture characteristics that are associated with the development of growing skull fractures and describe the authors' institutional experience managing this rare entity., Methods: A retrospective cohort study was performed that included all patients younger than 5 years presenting to a single institution with skull fractures from 2003 to 2017. Patient demographics, cause of injury, skull fracture characteristics (e.g., amount of diastasis, linear versus comminuted fracture), concomitant neurologic injuries, and management outcomes were recorded. Potential factors contributing to the development of a growing skull fracture and neurologic injuries associated with growing skull fractures were evaluated using univariate logistic regression., Results: A total of 905 patients met the authors' inclusion criteria. Of these, six (0.66 percent) were diagnosed with a growing skull fracture. Growing skull fractures were more likely to be comminuted (83.3 percent versus 40.7 percent; p = 0.082) and to present with diastasis on imaging (100 percent versus 26.1 percent; p < 0.001; mean amount of diastasis, 7.1 mm versus 3.1 mm; p < 0.001). Univariate logistic regression analysis confirmed the role of a comminuted fracture pattern (OR, 7.572) and the degree of diastasis (OR, 2.081 per mm diastasis) as significant risk factors for the development of growing skull fractures., Conclusions: The authors' analysis revealed that fracture comminution and diastasis width are associated with the development of growing skull fractures. The authors recommend dural integrity assessment, close follow-up, and early management in young children who present with these skull fracture characteristics., Clinical Question/level of Evidence: Risk, III.

Background: Nasoorbitoethmoid fractures commonly accompany midface fractures and may be underdiagnosed, resulting in incomplete reconstruction or inadequate treatment following facial trauma. To better understand the nasoorbitoethmoid fracture diagnosis and treatment tendencies, the authors analyzed concomitant nasoorbitoethmoid injuries in the setting of zygoma fractures., Methods: The facial trauma database at a level I trauma center was evaluated. All patients with diagnosed zygoma fractures from June of 2011 to March of 2016 were assessed for a concomitant nasoorbitoethmoid injury. Documentation of these fractures in radiology, plastic surgery, and operative notes was recorded, as was the rate of nasoorbitoethmoid fracture surgical repair., Results: The authors identified 339 eligible patients and completed retrospective analysis of computed tomographic images for their 356 zygoma fractures. The incidence of concomitant nasoorbitoethmoid fractures was 30.6 percent (109 of 356). Documentation rates of nasoorbitoethmoid fractures were 0 percent, 3.7 percent, and 8.3 percent in radiology, plastic surgery, and operative notes, respectively. The rate of surgical correction of nasoorbitoethmoid injuries was 22.9 percent (25 of 109). Of those fractures identified, 44.9 percent (49 of 109) were minimally displaced or nondisplaced. Subset analysis of only significantly displaced fractures yielded an incidence of 16.8 percent (60 of 356). Of significantly displaced fractures, documentation rates were 0 percent, 6.7 percent, and 16.8 percent in radiology, plastic surgery, and operative notes, respectively. The surgical repair rate of significantly displaced fractures was 31.7 percent (19 of 60)., Conclusions: These findings suggest a high concomitance rate of nasoorbitoethmoid fractures with zygoma fractures and identify a tendency to underdocument and undertreat this injury pattern. Clinicians managing patients with midface trauma should have a high suspicion for nasoorbitoethmoid trauma. Plastic surgeons and radiologists should be better trained in identifying the nasoorbitoethmoid fracture pattern.

The objective of our study was to assess the reliability of the estimation of posttraumatic survival time (PTST) in forensic cases based on microCT and histology of putrefied/dry bone samples with comparison of initial macroscopic fracture classification performed during autopsy. Macroscopic morphological patterns of bone fracture are routinely used in forensic pathology and anthropology to distinguish between antemortem, perimortem and postmortem injuries. Based on macroscopic and microscopic analysis of six craniofacial fractures, our study results illustrate the need to complete macroscopical findings and initial fracture classification with microscopic analysis to avoid any inaccuracy. MicroCT has become a powerful technique to identify early bone healing signs but histology remains the gold standard to estimate the PTST and determine vital fracture based on hemorrhage marker. Raman microspectroscopy can identify a blood clot in the fracture line., (Copyright © 2020 Elsevier Masson SAS. All rights reserved.)

Objectives: To assess whether head CT with 3D reconstruction can replace skull radiographs (SXR) in the imaging investigation of suspected physical abuse (SPA)/abusive head trauma (AHT)., Methods: PACS was interrogated for antemortem skeletal surveys performed for SPA, patients younger than 2 years, SXR and CT performed within 4 days of each other. Paired SXR and CT were independently reviewed. One reviewer analysed CT without and (3 months later) with 3D reconstructions. SXR and CT expert consensus review formed the gold standard. Observer reliability was calculated., Results: A total of 104 SXR/CT examination pairs were identified, mean age 6.75 months (range 4 days to 2 years); 21 (20%) had skull fractures; two fractures on CT were missed on SXR. There were no fractures on SXR that were not seen on CT. For SXR and CT, respectively: PPV reviewer 1, 95% confidence interval (CI) 48-82% and 85-100%; reviewer 2, 67-98% and 82-100%; and NPV reviewer 1, 95%, CI 88-98% and 96-100%; reviewer 2, 88-97% and 88-98%. Inter- and intra-observer reliability were respectively the following: SXR, excellent (kappa = 0.831) and good (kappa = 0.694); CT, excellent (kappa = 0.831) and perfect (kappa = 1). All results were statistically significant (p < 0.001)., Conclusions: CT has greater diagnostic accuracy than SXR in detecting skull fractures which is increased on concurrent review of 3D reconstructions and should be performed in every case of SPA/AHT. SXR does not add further diagnostic information and can be omitted from the skeletal survey when CT with 3D reconstruction is going to be, or has been, performed., Key Points: • Head CT with 3D reconstruction is more sensitive and specific for the diagnosis of skull fractures. • Skull radiographs can be safely omitted from the initial skeletal survey performed for suspected physical abuse when head CT with 3D reconstruction is going to be, or has been, performed.

The purpose of this study was to identify factors associated with the risk of closed head injury (CHI) in children under age 2 years with suspected minor head injuries based on age-appropriate, or near age-appropriate, mental status on an exam. The study was a secondary data analysis of a public-use dataset from the largest prospective, multicenter pediatric head injury study found in the current literature. An existing, validated clinical decision rule was examined using a sample of 3,329 children under age 2 to determine whether it, or the individual variables within it, could be utilized alone, or in conjunction with other variables to accurately predict the risk of underlying CHI in this sample. Results indicated that the keys to an accurate triage assessment for children under age 2 with suspected minor head injuries include the ability to identify the specific skull region injured, the ability to assess for the presence and size of any scalp hematoma, the ability to identify signs of altered mental status in this age group, and having access to accurate information regarding the child's age and the details of the injury mechanism. The findings from this study add to the body of knowledge regarding what factors are associated with CHI in children under age 2 with suspected minor head injuries and could be used to inform age-specific recommendations for children under age 2 in triage, educational resources, and national trauma criteria., (© 2019 Wiley Periodicals, Inc.)

Two current approaches to the ergometric evaluation of the impact strength that lead to skull fracture are described. Within each of them, the features of particular techniques, typical expert errors, ways and means of preventing them are analyzed. Quantitative data on the contribution of various initial parameters (fracture type, age, bone thickness, skull radius of curvature, body weight, height, etc.) to the result of computational diagnostics are presented.

Background: Blunt cerebrovascular injury (BCVI) occurs in <1% of pediatric patients. The two principal screening criteria for BCVI in children are the Utah and McGovern Score with motor vehicle accident (MVA) considered to be a predictor for BCVI. We sought to confirm previously reported risk factors and identify novel associations with BCVI in pediatric patients., Methods: The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for patients younger than 16 years presenting after blunt trauma. A multivariable logistic regression was used to determine risk of BCVI., Results: From 69,149 pediatric patients, 109 (<0.2%) had BCVI. The median age was 13 years, and the median Injury Severity Score was 25. More than half the patients were involved in MVAs (53.2%) and had a skull base fracture (53.2%). Factors independently associated with BCVI include skull base fracture (odds ratio [OR], 3.84; 95% confidence interval [CI], 2.40-6.14; p < 0.001), cervical spine fracture (OR, 3.15; 95% CI, 1.91-5.18; p < 0.001), intracranial hemorrhage (OR, 3.11; 95% CI, 1.89-5.14; p < 0.001), Glasgow Coma Scale score of 8 or less (OR, 2.11; 95% CI, 1.33-3.54; p = 0.003), and mandible fracture (OR, 1.99; 95% CI, 1.05-3.84; p = 0.04). Motor vehicle accident was not an independent predictor for BCVI (p = 0.07)., Conclusion: In the largest analysis of pediatric BCVI to date, skull base fracture had the strongest association with BCVI. Other associations to pediatric BCVI included cervical spine and mandible fracture. Motor vehicle accident, previously identified to be associated with BCVI, was not an independent risk factor in our analysis. A future multicenter study incorporating newly identified variables in a scoring system to screen for BCVI is warranted., Level of Evidence: Level IV (Prognostic/Epidemiologic).

Background and Purpose: Differentiating Abusive Head Trauma (AHT) from Non-abusive Head trauma (NAHT) has profound clinical prognostic and legal implications, as certain imaging findings can individually be more suggestive of NAHT, while others are more suggestive of AHT. This study was set out to evaluate for an association between the various imaging findings in AHT with outcome., Material and Methods: Over 7-years, 55 children (age 0-4 years') with head trauma and magnetic resonance imaging (MRI) were included as either: abusive (n = 16), non-abusive (n = 35), or indeterminate (n = 4). Two pediatric neuroradiologists jointly reviewed the imaging. The frequency of imaging findings and their association with ≥6 months' outcome were calculated., Results: Comparing abusive versus non-abusive head trauma, complex subdural hematoma was present in 81% (n = 13/16) and 29% (n = 10/35), hypoxic-ischemic injury in 44% (n = 7/16) and 6% (n = 2/35), and diffuse axonal injury in 12% (n = 2/16) and 26% (n = 9/35), respectively. Susceptibility-weighted imaging (SWI) retinal hemorrhages were absent in non-abusive trauma (0/35), but present in 44% (n = 7/16) of the abusive group. In abuse, simple subdural hematomas were absent. Significant associations were found between the presence of abusive trauma with both hypoxic ischemic insult (OR = 12.83, p = 0.0024) and complex subdural hematoma (OR = 10.83, p = 0.0007). The presence of hypoxic ischemic injury (HII) did correlate significantly with clinical outcome (p = 0.017), while retinal hemorrhages on SWI and complex subdural hematoma did not (p = 0.1696-p = 0.2496)., Conclusion: Neuroimaging findings can be helpful in discriminating these two conditions on presentation, as well as in helping solidify the suspicion of AHT. Regarding eventual outcome in AHT, the most important predictor is clearly HII.

Background: In automotive events, head injuries (skull fractures and/or brain injuries) are associated with head contact loading. While the widely-used head injury criterion is based on frontal bone fracture and linear accelerations, injury risk curves were not developed from original datasets., Objectives: Develop skull fracture-based risk curves for using previously published data and apply resampling techniques to assess their qualities., Methods: Force, deflection, energy, and stiffness data from thirteen human cadaver head impact tests were used to develop risk curves using parametric survival analysis. Injuries occurred to all specimens. Data points were treated as uncensored. Variables were ranked, and the variable best explaining the underlying fracture response was determined using the Brier Score Metric (BSM). The qualities of the risk curves were determined using normalized confidence interval sizes. Statistical resampling methods were used to assess the quality of the risk curves and the impact of the sample size by conducting 2000 simulations. Sample sizes ranged from 13 to 26., Findings: The Weibull distribution was optimal for all the response variables, except deflection (log-logistic). The quality of the risk curves was the highest for deflection. This variable best explained the underlying head injury response, based on BSM. Improvements in the quality of the risk curves were achieved with additional samples of force and deflection (<13), while energy and stiffness variables required more size. Individual risk curves are given., Interpretation: These probability curves from head contact loading add to the understanding skull fractures and can be used to improve safety in injury producing environments., (Published by Elsevier Ltd.)

Purpose: The aim of this study was to evaluate the effect of combining human parathyroid hormone (1-34) (PTH 1-34 ; PTH) and menaquinone-4 (MK-4) on calvarial bone defect repair in osteopenic rats., Methods: Fourteen week olds were subject to craniotomy for the establishment of osteopenic animal models fed through a chronically low-protein diet. After that, critical calvarial defect model was established and all rats were randomly divided into four groups: sham, MK-4, PTH, and PTH + MK-4. The animals received MK-4 (30 mg/kg/day), PTH 1-34 (60 μg/kg, three times a week), or PTH 1-34 (60 μg/kg, three times a week) plus MK-4 (30 mg/kg/day) for 8 weeks, respectively. Serum γ-carboxylated osteocalcin (Gla-OC) levels, histological and immunofluorescent labeling were employed to evaluate the bone formation and mineralization in calvarial bone defect. In addition, Microfil perfusion, immunohistochemical, and micro-CT suggested enhanced angiogenesis and bone formation in calvarial bone healing., Results: In this study, treatment with either PTH 1-34 or MK-4 promoted bone formation and vascular formation in calvarial bone defects compared with the sham group. In addition, combined treatment of PTH 1-34 plus MK-4 increased serum level of Gla-OC, improved vascular number and vascular density, and enhanced bone formation in calvarial bone defect in osteopenic conditions as compared with monotherapy., Conclusions: In summary, this study indicated that PTH 1-34 plus MK-4 combination therapy accelerated bone formation and angiogenesis in calvarial bone defects in presence of osteopenia.

Object : Although contact sport-related head injuries are frequently reported, golf cart accidents may have significant consequences including severe traumatic brain injury (TBI) or head injury. As no standardized regulations exist, this mechanism may be underreported. Methods : A retrospective review of TBI or cranial trauma after a golf cart accident at a level I trauma center over 5 years were performed. Data regarding age, sex, race, initial Glasgow Coma Scale score, alcohol status, type and location of the injury, and outcomes were analyzed and reported in terms of Modified Rankin Scale (MRS). Results : A total of 23 patients with TBI or cranial trauma following golf cart accident were identified. The mean age was 36 years old with the most common injury being skull fracture followed by acute subdural hematoma. Most patients had good outcomes, MRS 0-3, at discharge, but like most forms of TBI, surgical interventions, intracranial pressure monitoring, post-traumatic seizures, hydrocephalus, and death did occur. Conclusions : Head injuries sustained by golf cart accidents are not insignificant and may be underreported. More awareness of these injuries and safety guidelines are needed.

Background: The purpose of this study was to determine if a pediatric neurosurgical consultation for isolated linear skull fractures (ILSF) in pediatric patients with Glasgow Coma Scale (GCS) scores of ≥14 changed their management., Methods: A 10-year retrospective chart review at a Level 1 Pediatric Trauma Center was performed. Exclusion criteria were age > 18 years, open, depressed, or skull base fractures, pneumocephalus, poly-trauma, any hemorrhage (intraparenchymal, epidural, subdural, subarachnoid), cervical spine fractures, penetrating head trauma, and initial GCS scores ≤13. Primary outcomes were neurosurgery recommendations to change acuity of care, obtain additional imaging studies, and perform invasive procedures. Secondary outcomes were patient demographics, injury type, transfer status, admitting service, length of hospital stay, consult location, and clinical course., Results: There were 127 cases of ILSF meeting study criteria with an average age of 2.36 years. Unilateral parietal bone fracture was the most common injury (46.5%). Falls were the most common mechanism (81.1%). All patients received pediatric neurosurgical consultations within 24 h of hospital arrival. There were no neurosurgical recommendations to obtain additional imaging studies, change acuity of care, or perform invasive procedures., Conclusions: Routine neurosurgical consultation in children with ILSF and GCS 14-15 does not appear to alter clinical management., (© 2019 S.

Bilateral skull fractures in infancy may result from accidental or abusive injury. Consultation with a child abuse pediatrician may assist with determining the likelihood of accident or abuse. Diagnostic considerations for the infant with bilateral skull fractures are reviewed, including single impact, double impact, and compression mechanisms of injury, as well as the possibility of accessory sutures as skull fracture mimics. Illustrative cases exemplify the evaluative process, including obtaining a detailed history, assessing for the presence or absence of additional physical or radiographic signs of injury, screening for psychosoical risk, and obtaining three-dimensional reconstruction of CT bone images. An understanding of plausible mechanisms of injury that can result in bilateral skull fractures in infancy can assist with making an accurate determination of likelihood of accident or abuse.

Aim: To identify, report, and raise awareness of the risk factors for television (TV) tip-over., Material and Methods: In total, 86 children who were brought to the emergency service and hospitalized at the neurosurgery clinic because of TV tip-over-related head trauma between August 2011 and August 2016 were included in the study., Results: The 86 patients consisted of 47 males and 39 females. The mean age was 38.8 ± 19.5 (9â€"102) months. Low education level of the mother was a risk factor for this type of accident (p=0.009). In all the patients, injuries were caused by the tip-over of a cathode ray tube (CRT) TV. In 66 patients (77%), only the TV tipped over onto the child, whereas in 20 cases (23%), the TV tipped over with the TV stand. The TVs were not fixed to the stand or the wall in any of the homes. According to computerized tomography findings, 12 patients (13.9%) had intracranial hemorrhage and 19 patients (22%) had skull fractures. Five patients underwent neurosurgical intervention. Eighty-four patients (97.6%) were discharged with a GCS level of 15. One patient was discharged with a GCS level of 9/15 with a tracheostomy and nasogastric tube. One patient died., Conclusion: TV tip-over causes physical injury that may result in serious neurological damage and even death. It is becoming more common and may be prevented by taking simple precautions.

Since the nose is at the center of the face, small changes to it can cause a big overall change. Therefore, a nasal fracture needs to be operated on when deformity is expected. Although many taxonomies have been developed for nasal bone fractures, no study has aimed to predict individual patient satisfaction. Herein, the authors tried to determine any correlation between the existing classifications of nasal bone fractures and subjective patient satisfaction. A retrospective study and telephone survey were conducted in 149 patients who underwent closed reduction for a pure nasal bone fracture. Pretraumatic, prereduction, and postoperative patient satisfactions were measured on a numerical scale from 1 to 5. The difference between pretraumatic and prereduction satisfactions was calculated to confirm the change in short-term satisfaction after trauma. The difference between pretraumatic and preoperative satisfactions was measured to determine change in long-term satisfaction postoperatively. The Stranc Robertson classification, modified Murray classification, and the presence of septal fracture were used to classify fractures. Independent and Jonckheere-Terpstra t tests were used in statistical analysis. Only 86 of 149 were included in the study. There was no significant difference in patient satisfaction among frontal/lateral (P = 0.70, 0.56), frontal I/II (P = 1.00, 0.24), and lateral I/II groups (P = 0.57, 0.67) according to the Stranc Robertson classification. Septal fracture (P = 0.21, 0.44) and the modified Murray classification (P = 0.14, 0.47) also had no effect on satisfaction. Existing classification systems have the advantage of reflecting and distinguishing the characteristics of fractures, but there is a limit in their ability to reflect subjective patient satisfaction.

Purpose: Fracture of the frontal bone can be accompanied by damage to the optic canal. The present study uses finite element analysis to identify fracture patterns, suggesting the involvement of the optic canal., Methods: Ten finite-element skull models were generated from computer tomography data of 10 persons. Then, dynamic analyses simulating collision of a 2-cm-radius brass ball to 6 regions on the frontal bone in the 10 models were performed. Fracture patterns presented by the frontal bone in the 60 experiments were observed, and all those involving the optic canal were selected. Commonalities of the selected fracture patterns were identified., Results: Fracture of the optic canal was observed in 9 of the 60 patients. In all 9 patients, fracture existed on the anterior and posterior walls of the frontal sinus and on the superior orbital wall., Conclusion: When the anterior and posterior walls of the frontal sinus and the superior orbital wall are all broken, the optic canal is highly likely to be involved in the damage. When this pattern is observed in emergency examination, preventive decompression of the optic nerve should be considered to avoid potential occurrence of blindness.

Although vascular complications after head trauma is well recognized, basilar artery entrapment within the longitudinal clivus fracture is rare. A 69-year-old man presented with progressive disturbance of consciousness and right hemiplegia after trauma. Computed tomography scan showed a right-sided acute subdural hematoma and multiple skull fractures, including a longitudinal clivus fracture. Magnetic resonance imaging revealed basilar artery occlusion and a small infarction at the ventral part of the pons. On the assumption of acute arterial occlusion caused by thrombus, endovascular thrombectomy was attempted, but resulted in perforation. After the procedure, basilar artery entrapment within the longitudinal clivus fracture turned out to be the cause of the occlusion. The present case suggests that basilar artery entrapment within the longitudinal clivus fracture is a possible cause of neurological deficits after trauma. In this subset, endovascular intervention without a correct diagnosis of this phenomenon is high risk.

A total of three hundred and fourteen patients with maxillofacial fracture under 14 years old were treated at Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Zhengzhou University from October 2010 to October 2017 were collected and retrospective analysis was conducted. Age, gender, injury factors, type of fracture, associated injuries and treatment has been analysed. There were 196 male and 118 female. The most common injury factor was fall (148 cases), accounting for 47.1% of all patients. The most common fracture type was mandible fracture (221 cases). Children are not very cooperative with clinical examination, which often leading to misdiagnosis. Age, gender, fracture injury factors, comorbidity and treatment were analyzed to provide the reference for the prevention, diagnosis and treatment.

Objectives: Swimming has been reported as the most common recreational activity among American youths, while diving remains a popular youth activity as well. We characterize the most common facial injuries occurring during these activities and evaluate facial fracture mechanisms and demographic trends, as this information may be helpful in preventative counseling as well as diagnosis., Methods: The National Electronic Injury Surveillance System was assessed for swimming- and diving-related facial injuries in children from 2007 to 2016. Estimates of national injury incidence were recorded, and patient diagnoses, demographics, and injury mechanisms were evaluated., Results: In the 10-year period assessed, 789 NEISS entries extrapolated to an estimated 27,709 patients nationwide were analyzed. The yearly incidence fluctuated but steadily rose from 2013 to 2016. Males comprised a majority of injuries (58%), and laceration was the most common diagnosis (65%), followed by abrasion/contusion (22%) and fracture (9%). Facial fractures were most likely to involve the nasal bones (87%). Swimming injuries were more numerous overall (74%), but a greater proportion of diving injuries resulted in fracture (12% vs. 7%). Teenagers were also more likely to suffer fractures than were younger children involved in the same activities., Conclusion: Most analyses of swimming and diving injuries have focused on spinal and orthopedic trauma. Nevertheless, the nature of headfirst diving and swim strokes suggest facial trauma is an underappreciated concern for clinicians. These findings reinforce the need for safer swimming and diving practices and serve as a useful resource for physicians managing pediatric facial injuries., (Copyright © 2018 Elsevier B.V.

Objectives: Nasal bone is prone to injury due of its prominent position on the face. Epidemiologic surveys are necessary to investigate nasal traumas. The aim of the present study is to examine the distribution of trauma etiologies according to age, sex, and seasonality in pediatric patients who present with nasal trauma, and to classify the pathologies according to their etiology as nasal fractures or nasal soft tissue injuries., Methods: A total of 200 pediatric patients aged between 0 and 18 years who were admitted to the emergency room with sustained nasal trauma between September 1, 2015 and August 1, 2016 and who were diagnosed with an either nasal fracture or nasal soft tissue injury were retrospectively analyzed. The relationship between the nasal bone fractures and nasal soft tissue injuries and age, sex, admission date, and trauma etiology were investigated., Results: Of 200 patients, 70.5% were males and 29.5% were females with a mean age of 8.93 ± 5.50 years. Of these patients, 33.0% were in the 0 to 5 years age group, 24.0% were in the 6 to 10 years age group, 18.5% were in the 11 to 14 years age group, and 24.5% were in the 15 to 18 years age group. Of these, 82.5% had a nasal soft tissue injury and 17.5% had a nasal fracture. The etiology of trauma was most commonly fall from a height in 42.5% of the patients. Impact injuries and falls were the most common etiologies in the 0 to 5 age group, falls were the most common etiologies in the 6 to 10 age group, sports injuries were the most common etiologies in the 11 to 14 age group, and physical assault was the most common etiology in the 15 to 18 age group (P = 0.001; P < 0.01). According to the paired comparisons, the rate of nasal fracture in the 0 to 5 age group was significantly higher than the rates in the 11 to 14 (P = 0.001) and 15 to 18 (P = 0.001) age groups (P < 0.05). The rate of nasal soft tissue injuries was significantly higher in the patients presenting to the emergency room with sustained impact injury to the nose or falls. The majority of the patients presenting with physical assault and sports injuries were males. Nasal soft tissue injuries were mostly seen in girls, whereas the rate of nasal fractures was higher in boys, which was directly proportional to the trauma etiology and severity of injury. The patients often presented in the summer season., Conclusion: Our study results suggest that age, sex, time of trauma, and type of trauma guide the diagnosis of specific pathologies in pediatric patients presenting with sustained trauma. These characteristics must be specifically questioned and taken into consideration in the follow-up and treatment.

Acute bilateral post-traumatic facial paralysis is rare in the literature. Post-traumatic facial paralysis is frequently accompanied transverse fractures of temporal more. The incidence of acute bilateral post-traumatic facial paralysis has been reported as 1 to 5 per million in the literature. Trauma and concurrent facial paralysis are usually in the same subsite (right temporal bone fracture and right facial paralysis). There is one pathophysiological pattern for a single temporal bone fracture in a subsite. The authors present a bilateral isolated different pathophysiological pattern sudden onset facial paralysis in a patient herein.

Spontaneous newborn skull fracture is rarely cited in nursing literature as a potential outcome of persistent fetal occiput posterior position. Although most newborns seem unaffected by the condition initially, some may show symptoms several hours after the birth, when nursing assessments are less frequent. This case report illustrates delayed newborn symptoms that led to an unexpected diagnosis of spontaneous skull fracture., (Copyright © 2018 AWHONN. Published by Elsevier Inc. All rights reserved.)

Purpose: Virtual reconstruction of large cranial defects is still a challenging task. The current reconstruction procedures depend on the surgeon's experience and skills in planning the reconstruction based on mirroring and manual adaptation. The aim of this study is to propose and evaluate a computer-based approach employing a statistical shape model (SSM) of the cranial vault., Methods: An SSM was created based on 131 CT scans of pathologically unaffected adult crania. After segmentation, the resulting surface mesh of one patient was established as template and subsequently registered to the entire sample. Using the registered surface meshes, an SSM was generated capturing the shape variability of the cranial vault. The knowledge about this shape variation in healthy patients was used to estimate the missing parts. The accuracy of the reconstruction was evaluated by using 31 CT scans not included in the SSM. Both unilateral and bilateral bony defects were created on each skull. The reconstruction was performed using the current gold standard of mirroring the intact to the affected side, and the result was compared to the outcome of our proposed SSM-driven method. The accuracy of the reconstruction was determined by calculating the distances to the corresponding parts on the intact skull., Results: While unilateral defects could be reconstructed with both methods, the reconstruction of bilateral defects was, for obvious reasons, only possible employing the SSM-based method. Comparing all groups, the analysis shows a significantly higher precision of the SSM group, with a mean error of 0.47 mm compared to the mirroring group which exhibited a mean error of 1.13 mm. Reconstructions of bilateral defects yielded only slightly higher estimation errors than those of unilateral defects., Conclusion: The presented computer-based approach using SSM is a precise and simple tool in the field of computer-assisted surgery. It helps to reconstruct large-size defects of the skull considering the natural asymmetry of the cranium and is not limited to unilateral defects.

Clival fracture is a rare and serious injury, which mostly results in the death of the victim before reaching the hospital. The entity is hardly diagnosed in the early phase because of high mortality rates and deficiencies in completion of radiological imaging. The incidence of diagnoses increased year by year after the usage of computed tomography gained widespread availability. In this article, we aimed to present radiological and clinical characteristics of a 5-year-old patient brought to the emergency department after a motor vehicle accident. The most current recommendations with regard to the management of clival fracture of a pediatric patient are also discussed.

Introduction: The C-3PO rule has been validated for use by emergency physicians to identify young children at risk of skull fracture following head trauma. The use of the rule by triage nurses could improve patient flow in the emergency department., Objectives: To evaluate the interobserver agreement of triage nurses and emergency physicians in the interpretation of the C-3PO rule in a pediatric emergency department., Methods: This was a prospective observational study performed in a consecutive sample of children visiting a single emergency department. Participants were all children younger than 24 months of age who presented at the emergency department for head trauma that had occurred in the previous 24 hours. The primary outcome was the interobserver agreement between nurses and emergency physicians as to whether the child was at high risk of skull fracture according to the interpretation of the C-3PO rule. All study participants were evaluated sequentially by a triage nurse and an emergency physician. Outcome of evaluation was kept blinded between nurses and physicians. The primary analysis was the interrater reliability using the kappa score. The sample size was set to provide lower boundary of 0.70 for a 95% confidence interval (95% CI) for kappa coefficient of at least 0.80., Results: A total of 226 children were evaluated by a physician and a nurse. Among them, 10 had skull fractures. A total of 34 nurses and 42 physicians evaluated between 1 and 21 children. The interrater reliability was excellent, as demonstrated by a kappa score of 0.85 (95% CI: 0.77-0.92). Moreover, all children with skull fractures were categorized at "high risk" by the nurse and the physician., Conclusion: This study demonstrates an almost perfect interrater reliability between triage nurses and emergency physicians in interpreting the C-3PO rule when evaluating children who presented at an emergency department for head trauma.
