Treatments for congenital and acquired craniofacial (CF) bone abnormalities are limited and expensive. Current reconstructive methods include surgical correction of injuries, short-term bone stabilization, and long-term use of bone grafting solutions, including implantation of (i) allografts which are prone to implant failure or infection, (ii) autografts which are limited in supply. Current bone regenerative approaches have consistently relied on BMP2 application with or without addition of stem cells. BMP2 treatment can lead to severe bony overgrowth or uncontrolled inflammation, which can accelerate further bone loss. Bone marrow-derived mesenchymal stem cell-based treatments, which do not have the side effects of BMP2, are not currently FDA approved, and are time and resource intensive. There is a critical need for novel bone regenerative therapies to treat CF bone loss that have minimal side effects, are easily available, and are affordable. In this study we investigated novel bone regenerative therapies downstream of JAGGED1 (JAG1). We previously demonstrated that JAG1 induces murine cranial neural crest (CNC) cells towards osteoblast commitment via a NOTCH non-canonical pathway involving JAK2-STAT5 (1) and that JAG1 delivery with CNC cells elicits bone regeneration in vivo. In this study, we hypothesize that delivery of JAG1 and induction of its downstream NOTCH non-canonical signaling in pediatric human osteoblasts constitute an effective bone regenerative treatment in an in vivo murine bone loss model of a critically-sized cranial defect. Using this CF defect model in vivo, we delivered JAG1 with pediatric human bone-derived osteoblast-like (HBO) cells to demonstrate the osteo-inductive properties of JAG1 in human cells and in vitro we utilized the HBO cells to identify the downstream non-canonical JAG1 signaling intermediates as effective bone regenerative treatments. In vitro, we identified an important mechanism by which JAG1 induces pediatric osteoblast commitment and bone formation involving the phosphorylation of p70 S6K. This discovery enables potential new treatment avenues involving the delivery of tethered JAG1 and the downstream activators of p70 S6K as powerful bone regenerative therapies in pediatric CF bone loss.

Purpose: During coronavirus disease-19 (COVID-19) pandemic, hospitals faced challenges which were different than previous years. The purpose this study was to report frequency of firearm injuries (FI) to head and neck during the COVID-19 pandemic. Materials and Methods: This cross-sectional study reviewed patients in the Trauma Registry at Grady Memorial Hospital (GMH) in Atlanta, GA. Patients were included if they sustained FI to head and neck, were listed in TR, and were treated at GMH. Patients were stratified according to date of injury into 1) before COVID-19 pandemic, (BC19) or 2) during initial 5 months of COVID-19 pandemic, (C19). Variables were patient demographics, illegal substance use, etiology, place of injury, distressed communities index, location of injury, Glasgow Coma scale on arrival, cardiopulmonary resuscitation in Emergency Department (ED), shock on admission, disposition from ED, length of stay, days on mechanical ventilation and discharge status. Descriptive, univariate, and bivariate analysis were completed. Chi square test was used for categorical variables. Statistical significance was P < .05. Results: There were 215 patients who met inclusion criteria. There were 96 patients (78 males) with a mean age of 31.5 years old during BC19. There were 119 patients (101 males) with a mean age 32.7 years old during C19. There was a 10.4% increase in FI to head and neck during COVID-19. Our data showed that alcohol use was associated with FI during C19 (P≤ .0001). FI to base of skull occurred 34.5% more often during C19 (P = .002). Cranial injuries occurred 26% more often during BC19 (P = .03). During BC19, 85.4% of the patients arrived alive to GMH, but only 16% arrived alive during C19 (P ≤ .0001). Conclusions: There were more FI to head and neck during COVID-10 pandemic than during the previous time period.

Objective: The coronavirus disease 2019 (COVID-19) pandemic caused delays in medical and surgical interventions in most health care systems worldwide. Oral and maxillofacial surgeons (OMSs) delayed operations to protect themselves, patients, and staff. This article (1) presents one institution's experience in the management of pediatric craniomaxillofacial trauma during the COVID-19 pandemic and (2) suggests recommendations to decrease transmission. Methods: This was a retrospective review of children aged 18 years or younger who underwent surgery at Children's Healthcare of Atlanta in Atlanta, GA, between March and August 2020. Patients (1) were aged 18 years old or younger, (2) had one or more maxillofacial fractures, and (3) underwent surgery performed by an OMS, otolaryngologist, or plastic surgeon. Medical records were reviewed regarding (1) fracture location, (2) COVID-19 status, (3) timing, (4) personal protective equipment, and (5) infection status. Descriptive statistics were computed. Results: Fifty-eight children met the inclusion criteria. The most commonly injured maxillofacial location was the nose. Operations were performed 50.9 hours after admission. Specific prevention perioperative guidelines were used with all patients, with no transmission occurring from a patient to a health care worker. Conclusions: With application of our recommendations, there was no transmission to health care workers. We hope that these guidelines will assist OMSs during the COVID-19 pandemic.

Involvement of the temporomandibular joint (TMJ) is common in juvenile idiopathic arthritis (JIA). TMJ arthritis can lead to orofacial symptoms, orofacial dysfunction, and dentofacial deformity with negative impact on quality of life. Management involves interdisciplinary collaboration. No current recommendations exist to guide clinical management. We undertook this study to develop consensus-based interdisciplinary recommendations for management of orofacial manifestations of JIA, and to create a future research agenda related to management of TMJ arthritis in children with JIA. Recommendations were developed using online surveying of relevant stakeholders, systematic literature review, evidence-informed generation of recommendations during 2 consensus meetings, and Delphi study iterations involving external experts. The process included disciplines involved in the care of orofacial manifestations of JIA: pediatric rheumatology, radiology, orthodontics, oral and maxillofacial surgery, orofacial pain specialists, and pediatric dentistry. Recommendations were accepted if agreement was >80% during a final Delphi study. Three overarching management principles and 12 recommendations for interdisciplinary management of orofacial manifestations of JIA were outlined. The 12 recommendations pertained to diagnosis (n = 4), treatment of TMJ arthritis (active TMJ inflammation) (n = 2), treatment of TMJ dysfunction and symptoms (n = 3), treatment of arthritis-related dentofacial deformity (n = 2), and other aspects related to JIA (n = 1). Additionally, a future interdisciplinary research agenda was developed. These are the first interdisciplinary recommendations to guide clinical management of TMJ JIA. The 3 overarching principles and 12 recommendations fill an important gap in current clinical practice. They emphasize the importance of an interdisciplinary approach to diagnosis and management of orofacial manifestations of JIA.

Purpose: Pediatric dog bite injuries are one of the most common nonfatal injuries. During the COVID-19 pandemic, children stayed at home more than pre-pandemic. The effect of the pandemic on severity of dog bites to the face in children has not been examined. The objective of this study was to determine the frequency and severity of dog bite injuries to the face in children during the first year of the COVID-19 pandemic when compared to the previous year. Materials and Methods: A retrospective cohort study was conducted for children with dog bite injuries to the head and neck region who presented to the emergency department at Children's Healthcare of Atlanta from March 2019 to March 2021. The predictor variable was the time of injury, and this was divided into pre-lockdown [control group (March 15, 2019, to March 15, 2020), ie pre-L] and lockdown (March 15, 2019, to March 15, 2020), ie post-L. The outcome variable was severity of dog bite defined as one or more of the following: 1) patient required sedation or general anesthesia for repair, 2) 3 or more regions in the head and neck were involved, and/or 3) surgical consultation took place. The investigators used a two-sample t-test, multivariable linear regression models, and modified analysis of variance and multivariate ANOVA tests to analyze the data (P-value < .05 determined significance). Results: 712 children (370 males) with an average age of 6 years old (range, 7 months–18 years) fit the inclusion criteria. There were 381 cases in the pre-L and 331 in the post-L period. There were more cases on average per month pre-L (31.8 cases/month) than post-L (27.6 cases/month) (P-value = .26). There were 183 pre-L surgical consults compared to 75 post-L (48 vs 22.8% of cases, respectively; P-value ≤ .001). There were 52 pre-L cases that had 3 or more sites in the head and neck compared to 28 during the post-L period (P-value = .032). Conclusions: During the COVID-19 pandemic, there may have been a decrease in the severity of dog bite injuries. This trend may demonstrate a consequence that is not a direct result of the virus.

Contrast-enhanced magnetic resonance imaging (MRI) remains the most comprehensive modality to assess juvenile idiopathic arthritis (JIA)-related inflammation and osteochondral damage in the temporomandibular joints (TMJ). This study tested the reliability of a new JIA MRI scoring system for TMJ (JAMRIS-TMJ) and the impact of variations in calibration and reader specialty. Thirty-one MRI exams of bilateral TMJs were scored independently using the JAMRIS-TMJ by 20 readers consisting of radiologists and non-radiologist clinicians in three reading groups, with or without a calibrating atlas and/or tutorial. The inter-reader reliability in the multidisciplinary cohort assessed by the generalizability coefficient was 0.61–0.67 for the inflammatory and 0.66–0.74 for the damage domain. The atlas and tutorial did not improve agreement within radiologists, but improved the agreement between radiologist and non-radiologist groups. Agreements between different calibration levels were 0.02 to 0.08 lower by the generalizability coefficient compared to agreement within calibration levels; agreement between specialty groups was 0.04 to 0.10 lower than within specialty groups. Averaging two radiologists raised the reliability above 0.8 for both domains. Therefore, the reliability of JAMRIS-TMJ was moderate-to-good depending on the presence of specialty and calibration differences. The atlas and tutorial are necessary to improve reliability when the reader cohort consists of multiple specialties.

The coronavirus disease 2019 (COVID-19) is a pandemic.1 COVID-19 concentrates in the upper airway mucosa2; thus, procedures involving this location are considered high risk. The COVID-19 pandemic has resulted in a significant shortage of personal protective equipment (PPE) worldwide. Professional additive manufacturing providers, makers, and designers in the 3-dimensional (3D) printing community have posted free COVID-19–related 3D printer designs on their websites.1 , 3 Most oral and maxillofacial surgeons (OMSs) are familiar with 3D printing technology. We describe our method of using a 3D printer to print face shields to protect OMSs during the COVID-19 pandemic.

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1–6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1–2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2–3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9–3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality (5.4 (95%CI 4.3–6.7)). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Objective: The purpose of this study was to describe patterns of burns to the head and neck in children during the early COVID-19 pandemic. Study design: This cross-sectional study reviewed pediatric patients in the Burn Care Quality Platform Registry. Patients were included if they were ≤17.9 years old and had sustained burns to the head and neck. Patients were separated into the following groups: March 13 to September 13, 2019 (before COVID-19 pandemic, BC) or March 13 to September 13, 2020 (during the initial 6 months of the COVID-19 pandemic, C19). The study team collected patient-related variables, details regarding burn injury, burn severity, and hospital course. Univariate and bivariate analyses were calculated. The chi-squared test was used for categorical variables. Statistical significance was P < .05. Results: Fifty-five children with head and neck burn injuries were included. There was a 200% increase in burns to the head and neck region in children in April 2021 compared with previous year. Burns to head and neck in White children occurred more often during C19 (P = .03). The study revealed differences in timing of presentation (time of burn injury to emergency department admission) in different racial groups during (White children [P = .05]), and after the pandemic (African American children [P = .02]). Conclusions: There was a transient increase in burns to the head and neck region in children during the early pandemic compared with the historic cohort.

Introduction: Patients with juvenile idiopathic arthritis (JIA) and involvement of the temporomandibular joint (TMJ) often experience abnormal facial growth. Three-dimensional (3D) assessment of dentofacial growth deviation has become more common with advancement and commercialization of imaging technologies. However, no standardized guidelines exist for interpretation of 3D imaging in patients with JIA. The aim of this study was to propose and validate morphometric measures for the 3D radiographic assessment of dentofacial growth deviation in patients with JIA to enhance: 1) Description of dentofacial growth deviation; 2) Treatment planning; 3) Longitudinal follow-up. Methods: The study was conducted in a standardized sequential-phased approach involving: 1) Preliminary decision-making; 2) Item generation; 3) Test of content-validity; 4) Test of reliability; 5) Test of construct validity; 6) Establishment of final recommendations. Results: Twenty-one morphometric measures were evaluated. Based on results of reliability and validity-testing including subjects with JIA (n = 70) and non-JIA controls (n = 19), seven measures received a "high recommendation" score. Those measures were associated with posterior mandibular height, occlusal cant, mandibular asymmetry, mandibular inclination, and anterior/posterior lower face height. Nine other measures were "moderately recommended" and five received a "somewhat recommendation" score. Conclusion: Seven morphometric measures were considered very useful in the 3D assessment of growth deviation in patients with TMJ disease associated with JIA. These variables can be used to standardize the description of dentofacial deformities and to plan corrective interventions.
