ABSTRACT
BACKGROUND: Antiresorptive targeted cancer therapies, such as denosumab and bisphosphonates, are used in adults, but their application in pediatric cancer is more recent. Side effects such as osteonecrosis of the jaw (ONJ) observed in adults have curtailed use of these medications in the pediatric population. PURPOSE: This study assesses the frequency of ONJ, other side effects, and the indications for use of denosumab versus bisphosphonates in pediatric subjects. STUDY DESIGN, SETTING, SAMPLE: A retrospective cohort study of pediatric subjects who underwent bisphosphonate or denosumab therapy at our institution from 2007-2023 was conducted. Subjects aged ≥ 18 years at therapy initiation were excluded. INDEPENDENT VARIABLE: The independent variable was antiresorptive therapy divided into 2 groups, treatment with intravenous bisphosphonates or denosumab. MAIN OUTCOME VARIABLE(S): Primary outcomes were development of bisphosphonate-related and denosumab-related ONJ. Secondary outcomes included additional side effects. COVARIATES: ONJ risk factors, subject demographics, indications for use, timing, duration, and cumulative dose of antiresorptive therapy were abstracted. ANALYSES: Univariate and bivariate statistics were computed to describe the sample and measure associations between antiresorptive therapy and outcomes. P values < .05 conferred statistical significance. RESULTS: The sample was composed of 178 subjects with a mean age of 11.7 ± 6.1 years. There were 14 (7.9%) and 164 (92.1%) subjects treated with denosumab and bisphosphonate therapies, respectively. There were 0 cases of ONJ across all subjects. The most common indication for treatment was adjuvant targeted therapy for aggressive tumors and malignancy (39.3%) followed by osteoporosis (14.6%). Subjects treated with denosumab had higher frequencies of hypercalcemia and severe bone pain than subjects treated with bisphosphonates, 28.6% versus 1.2% (P < .001) and 14.3% versus 0.00% (P < .001), respectively. CONCLUSION AND RELEVANCE: While invasive dental procedures are ideally performed before antiresorptive treatment, our data suggest that bisphosphonates may be used safely in the pediatric population with low concern for ONJ. Our data also demonstrated bisphosphonates may have a more tolerable side effect profile than denosumab. If the perceived benefits are similar, we recommend using bisphosphonates as first-line therapy in children while reserving denosumab for refractory cases. Future studies will help determine long-term side effects and differences in efficacies of these medications.
ABSTRACT
PURPOSE: Becoming an oral-maxillofacial surgeon is often challenging for young trainees. The purpose of this manuscript is to explore how a student-led group, which emphasizes networking, mentorship, and academic opportunities, may impact one's journey to becoming an oral-maxillofacial surgeon. PATIENTS AND METHODS: This was a cross-sectional descriptive study where a 5-question Likert-type survey was administered to students who matriculated into residency and participated in a student-led group called Passing The Scalpel (PTS). This survey evaluated the value of PTS in providing exposure, career decision-making, networking/mentorship, and camaraderie. The results were analyzed, and statistical outcomes were evaluated. RESULTS: There was an 80.5% response rate (n = 29). Question 1 regarding first exposure to oral-maxillofacial surgery had a mean score of 2.55 (standard deviation [SD] = 1.35; χ2 = 15.39; P < .05). Question 2 regarding choosing oral-maxillofacial surgery as a career had a mean score of 3.66 (SD = 1.11; χ2 = 10.84; P < .05). Question 3 regarding offering mentorship and networking had a mean score of 4.14 (SD = 0.92; χ2 = 27.81; P < .05). Question 4 regarding increasing applicant camaraderie had a mean score of 4.21 (SD = 0.77; χ2 = 36.71; P < .05). Question 5 regarding the importance of PTS within a dental curriculum had a score of 4.48 (SD = 0.68; χ2 = 41.89; P < .05). CONCLUSION: PTS is an effective student-led initiative that emphasizes early exposure, networking, and mentorship opportunities and encourages students in choosing oral-maxillofacial surgery as a specialty. PTS demonstrates that student-led initiatives can fulfill unmet needs in the dental curriculum.

BACKGROUND: Alveolar bone grafting (ABG) using iliac crest bone graft (ICBG) is best practice for children with complete cleft lip and palate. With the advent of recombinant human bone morphogenetic protein (rhBMP-2) and demineralized bone matrix (DBM), excellent results can still be achieved while avoiding donor-site morbidity. This study aims to determine the critical-sized defects by analyzing graft failure rates for ICBG and rhBMP-2/DBM to guide surgeons performing ABG. METHODS: A retrospective review was conducted evaluating patients who underwent ABG from 2016-2022. Patients with preoperative and postoperative cone beam computed tomography (CBCT) imaging were included. Volumetric defect sizes were calculated using preoperative imaging. Graft success criteria were based on both clinical and radiographic outcomes. Logistic regressions analyzed graft failure rates to identify an optimal cutoff, which defined the critical-sized defect. RESULTS: Ninety-three patients were included. Bone graft cohorts included ICBG (n=30) and rhBMP-2/DBM (n=63). The critical-sized defects were calculated to be 810 mm 3 and 885 mm 3 for ICBG and rhBMP-2/DBM, respectively. There were significantly higher graft failure rates beyond the critical size compared to below for both ICBG (71.4% vs. 0.0%; p<0.001) and rhBMP-2/DBM (65.0% vs. 14.0%; p<0.001). CONCLUSION: This study identified critical-sized defects based on alveolar cleft volume for ICBG or rhBMP-2/DBM with higher graft failure rates beyond the predicted thresholds. Distinct ranges in cleft volume were identified where patients might benefit from each select graft option.
ABSTRACT
Severe infections of the neck can lead to life-threatening consequences when not treated promptly and correctly. This case report is the first to illustrate the successful use of an acellular dermal matrix to repair a tracheal defect in the setting of a severe neck infection. Laryngoscope, 133:1961-1963, 2023.
