Abstract
BACKGROUND Gingivoperiosteoplasty (GPP) can avoid secondary alveolar bone graft in up to 60% of patients. The effects of GPP on maxillary growth are a concern. However, palatoplasty can also negatively impact facial growth. This study quantifies the isolated effects of GPP and cleft palate repair on maxillary growth at the age of mixed dentition. METHODS A single-institution, retrospective study of all patients undergoing primary reconstruction for unilateral cleft lip and alveolus (CLA) or cleft lip and palate (CLP) was performed. Study patients had lateral cephalograms at the age of mixed dentition. Patients were stratified into four groups: CLA with GPP (CLA + GPP), CLA without GPP (CLA - GPP), CLP with GPP (CLP + GPP), and CLP without GPP (CLP - GPP). Cephalometric measurements included the following: sella-nasion-point A (SNA), sella-nasion-point B (SNB), and A point-nasion-B point. Landmarks were compared between patient groups and to Eurocleft center D data. RESULTS One hundred ten patients met inclusion criteria: seven CLA - GPP, 16 CLA + GPP, 24 CLP - GPP, and 63 CLP + GPP patients. There were no significant differences in SNA, SNB, and A point-nasion-B point between CLA + GPP and CLA - GPP, or between CLP + GPP and CLP - GPP groups. In patients who did not receive GPP, SNA was significantly lower in patients with a cleft palate compared with patients with an intact palate ( P < 0.05). There were no significant differences in SNA or SNB of CLP - GPP or CLP + GPP groups when compared with Eurocleft data. CONCLUSION When controlling for the effects of cleft palate repair, GPP does not appear to negatively affect midface growth at the age of mixed dentition. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Background: Socio-economic status, living environments, and race have been implicated in the development of different congenital abnormalities. As orofacial clefting is the most common anomaly affecting the face, an understanding of its prevalence in the United States and its relationship with different determinants of health is paramount. Therefore, the purpose of this study is to determine the modern prevalence of oral-facial clefting in the United States and its association with different social determinants of health. Methods: Utilizing Epic Cosmos, data from approximately 180 US institutions were queried. Patients born between November 2012 and November 2022 were included. Eight orofacial clefting (OC) cohorts were identified. The Social Vulnerability Index (SVI) was used to assess social determinants of health. Results: Of the 15,697,366 patients identified, 31,216 were diagnosed with OC, resulting in a prevalence of 19.9 (95% CI: 19.7-20.1) per 10,000 live births. OC prevalence was highest among Asian (27.5 CI: 26.2-28.8) and Native American (32.8 CI: 30.4-35.2) patients and lowest among Black patients (12.96 CI: 12.5-13.4). Male and Hispanic patients exhibited higher OC prevalence than female and non-Hispanic patients. No significant differences were found among metropolitan (20.23/10,000), micropolitan (20.18/10,000), and rural populations (20.02/10,000). SVI data demonstrated that OC prevalence was positively associated with the percentage of the population below the poverty line and negatively associated with the proportion of minority language speakers. Conclusions: This study examined the largest US cohort of OC patients to date to define contemporary US prevalence, reporting a marginally higher rate than previous estimates. Multiple social determinants of health were found to be associated with OC prevalence, underscoring the importance of holistic prenatal care. These data may inform clinicians about screening and counseling of expectant families based on socio-economic factors and direct future research as it identifies potential risk factors and provides prevalence data, both of which are useful in addressing common questions related to screening and counseling.

Abstract
BACKGROUND Pharmacologic agents are often used in the antepartum period, however, studies on their effect on fetal development are limited. Thus, this study aims to examine the effect of commonly prescribed antepartum medications on the development of orofacial clefting. METHODS Utilizing EPIC Cosmos deidentified data from approximately 180 US institutions was queried. Patients born between January 1, 2013, to January 1, 2023, were included. Eight OC cohorts were identified. Gestational medication use was identified by medications prescribed, provider-administered, or reported use by mothers. Medications used in at least 1 in 10,000 pregnancies were included in this analysis. RESULTS A total of 12 098 newborns with available maternal pharmacologic data were born with any type of orofacial clefting. Prevalence for all oral clefts, any cleft palate, and any cleft lip were 20.56, 18.10, and 10.60 per 10 000 individuals, respectively. Notable significant exposures include most anticonvulsants, such as lamotrigine (OR1.33, CI 1.10-1.62), and topiramate (OR1.35, CI 1.13-1.62), as well as nearly all SSRIs/SNRIs, including fluoxetine (OR1.34, CI 1.19-1.51), sertraline (OR1.25, CI 1.16-1.34), and citalopram (OR1.28, CI 1.11-1.47). Corticosteroids were also correlated including dexamethasone (OR1.19, CI 1.12-1.27), and betamethasone (OR1.64, CI 1.55-1.73), as were antibiotics, including amoxicillin (OR1.22, CI 1.14-1.30), doxycycline (OR1.29, CI 1.10-1.52), and nitrofuran derivatives (OR1.10, CI 1.03-1.17). CONCLUSION New associations between commonly prescribed antepartum medications and orofacial clefting were found. These findings should be confirmed as causality is not assessed in this report. Practitioners should be aware of the potential increased risk associated with these medications.

Abstract
OBJECTIVE The aim of this study was to evaluate the outcomes of orthognathic surgery (OGS) in patients with craniofacial microsomia (CFM) who had previously undergone mandibular distraction osteogenesis (MDO). DESIGN A retrospective cohort study was performed including all patients with CFM who were treated with OGS at a single institution between 1996 and 2019. The clinical records, operative reports, and cone beam computed tomography (CBCT) scans were reviewed. CBCT data before OGS (T1), immediately after OGS (T2), and at long-term follow-up (T3) were analyzed using Dolphin three-dimensional software to measure the occlusal cant and chin point deviation. RESULTS The study included 12 patients with CFM who underwent OGS (6 underwent OGS without MDO and 6 underwent OGS after MDO). There was a statistically significant improvement in occlusal cant and chin point deviation in both groups postoperatively. Occlusal cant relapsed by a mean of 0.6° (standard deviation [SD] 1.1°) in the patients who had OGS alone compared with 0.7° (SD 1.2°) in the patients who had OGS after MDO (P = .745) between T2 and T3. There was no statistically significant difference in chin point relapse between patients who had OGS alone compared with those who had OGS after MDO (0.1 mm [SD 2.5mm] vs 0.7mm [SD 2.2mm]; P = .808). CONCLUSIONS Within the limitations of this study, these findings suggest that OGS after MDO in patients with CFM can produce stable results.

Abstract
Nasoalveolar molding (NAM) is an early presurgical intervention to facilitate primary cleft lip repair by reducing cleft severity and improving labial and nasal form. However, it continues to be associated with the burden of care that influences access and completion of therapy. The authors, therefore, aim to determine the burden of care of NAM therapy for families seeking treatment at a high-volume urban cleft center. A retrospective study of all patients undergoing primary cleft repair between 2012 and 2020 was performed. Patients were grouped based on whether or not NAM therapy was offered. Variables including physical, psychosocial, and financial factors were assessed. Two hundred and thirty patients underwent primary cleft repair between 2012 and 2020. Of these, 176 patients were indicated for NAM, with 4% discontinuing, and 54 patients did not undergo NAM. The 169 patients who completed NAM had a mean duration of treatment of 13.6±8.8 wks consisting of 15±6 scheduled NAM adjustment visits and 1±1 unscheduled visit made urgently to assess caregiver concerns. The mean travel distance was 28.6±37.1 miles. Eighty-four percent of caregivers were married, and 16% did not have English as a primary language. Though 57% had private insurance, 43% of patients received charity support for their treatment. NAM is a finite presurgical intervention that requires caregivers to participate in patient care for approximately three months of their early life. The decision to pursue NAM should be considered alongside the burden of care for caregivers to complete treatment.

Abstract
INTRODUCTION The Abbe flap is a standard intervention to treat upper lip deformities in patients with bilateral cleft lip. This two-stage procedure requires a 2 to 3-week period in which the superior and inferior lips remain connected. This study evaluates the safety of Abbe flap division and inset prior to 14 days' time. MATERIALS AND METHODS A single institution, 8-year review of all patients with a bilateral cleft lip who underwent Abbe flap reconstruction was performed. Patients were classified into two groups: those whom division was performed 14 days or later and those with division earlier than 14 days. RESULTS A total of 26 patients were identified. Patients who underwent Abbe flap division in less than 14 days (n = 10) demonstrated an average time to division of 9.7 days (range 7-13 days) with no evidence of flap loss, wound breakdown or infection. Patients who underwent Abbe flap division within 14 days or more (n = 16) demonstrated an average time to division of 15 days with four minor complications and no flap loss. CONCLUSION Dividing the Abbe flap after the first postoperative week appears to be safe and without additional risk to flap loss or wound breakdown. A shorter time to Abbe flap division may decrease the burden of care on patients and their caregivers.

Abstract
BACKGROUND Many cleft centers incorporate NasoAlveolar Molding (NAM) into their presurgical treatment protocols. However, there are limited data on eligible patients who do not receive or complete NAM. This study characterizes the demographics associated with non-utilization or completion of NAM. METHODS A single-institution retrospective review was performed of all patients with cleft lip and alveolus undergoing primary unilateral and bilateral cleft lip repair from 2012-2020. Patients were grouped based on utilization or non-utilization of NAM. Demographic and treatment data were collected, including documented reasons for not pursuing or completing NAM. RESULTS Of 230 eligible patients, 61 patients (27%) did not undergo or complete NAM (no-NAM). In this group, 37 (60.7%) received no presurgical intervention, 12 (19.7%) received presurgical nostril retainers, 3 (4.9%) received lip taping, 1 (1.6%) received a combination of taping/nostril retainers, and 8 (13.1%) discontinued NAM. The most common reasons for not receiving NAM were sufficiently aligned cleft alveolus (21.3%), medical complexity (16.4%), late presentation (16.4%), and alveolar notching (18%). Compared to the NAM group, the no-NAM group had significantly lower rates of prenatal cleft diagnosis/consult, and significantly higher proportion of non-married and non-English speaking caregivers. Multivariable analysis controlling for insurance type, primary language, prenatal consult, marital status, and age at first appointment found that age at first appointment is the only statistically significant predictor of NAM utilization (P < .001). CONCLUSIONS Common reasons for non-utilization of NAM include well-aligned cleft alveolus, medical complexity, and late presentation. Early presentation is an important modifiable factor affecting rates of NAM utilization.

Abstract
Bone tissue has the capacity to regenerate under healthy conditions, but complex cases like critically sized defects hinder natural bone regeneration, necessitating surgery, and use of a grafting material for rehabilitation. The field of bone tissue engineering (BTE) has pioneered ways to address such issues utilizing different biomaterials to create a platform for cell migration and tissue formation, leading to improved bone reconstruction. One such approach involves 3D-printed patient-specific scaffolds designed to aid in regeneration of boney defects. This study aimed to develop and characterize 3D printed scaffolds composed of type I collagen augmented with β-tricalcium phosphate (COL/β-TCP). A custom-built direct inkjet write (DIW) printer was used to fabricate β-TCP, COL, and COL/β-TCP scaffolds using synthesized colloidal gels. After chemical crosslinking, the scaffolds were lyophilized and subjected to several characterization techniques, including light microscopy, scanning electron microscopy, and x-ray diffraction to evaluate morphological and chemical properties. In vitro evaluation was performed using human osteoprogenitor cells to assess cytotoxicity and proliferative capacity of the different scaffold types. Characterization results confirmed the presence of β-TCP in the 3D printed COL/β-TCP scaffolds, which exhibited crystals that were attributed to β-TCP due to the presence of calcium and phosphorus, detected through energy dispersive x-ray spectroscopy. In vitro studies showed that the COL/β-TCP scaffolds yielded more favorable results in terms of cell viability and proliferation compared to β-TCP and COL scaffolds. The novel COL/β-TCP scaffold constructs hold promise for improving BTE applications and may offer a superior environment for bone regeneration compared with conventional COL and β-TCP scaffolds.

Abstract
BACKGROUND This study characterizes the potential loss of velar length in patients with a wide cleft and rescue of this loss of domain by local flap reconstruction, providing anatomic evidence in support of primary lengthening of the soft palate during palatoplasty. METHODS A retrospective review was conducted of all patients with a cleft palate at least 10mm in width, who underwent primary palatoplasty with a buccal flap prior to 18 months of age over a 2-year period. All patients underwent primary palatoplasty with horizontal transection of the nasal mucosa, which was performed after nasal mucosa repair, but prior to muscular reconstruction. The resulting palatal lengthening was measured and the mucosal defect was reconstructed with a buccal flap. RESULTS Of the 22 patients included, 3 (13.6%) had a history of Pierre Robin sequence, and 5 (22.7%) had an associated syndrome. No patients had a Veau I cleft, 7 (31.8%) had a Veau II, 12 (54.5%) had a Veau III, and 3 had (13.6%) a Veau IV cleft. All patients had a right buccal flap during primary palatoplasty. The mean cleft width at the posterior nasal spine was 10.6 ± 2.82mm, and mean lengthening of the velum after horizontal transection of the nasal mucosa closure was 10.5 ± 2.23mm. There were 2 (9.1%) fistulas, 1 (4.5%) wound dehiscence, 1 (4.5%) 30-day readmission, and no bleeding complications. CONCLUSIONS Patients with a wide cleft palate have a potential loss of 1cm velar length. The buccal flap can rescue the loss of domain in palatal length, and potentially improve palatal excursion.

Abstract
OBJECTIVE Primary cleft nasal repair can include septal reconstruction. We hypothesize that primary cleft septoplasty and adult septoplasty have fundamental differences that render these procedures as distinct surgical entities. DESIGN Systematic review of the PubMed, Cochrane, and Embase databases performed on pediatric cleft and general adult septoplasty techniques through December 2021. (PROSPERO ID CRD42022295763). MAIN OUTCOME MEASURES Collected data included information on septal dissection, septal detachment, and management of the bony and cartilaginous septum. RESULTS Twenty-eight pediatric cleft septoplasty and 229 adult septoplasty studies were included. Dissection in primary cleft septoplasty was limited to the anterocaudal septum, while secondary cleft septoplasty and adult septoplasty techniques entailed wide exposures of the cartilaginous septum with or without exposure of the perpendicular plate of the ethmoid. In primary cleft septoplasty, detachment of the septum was mostly limited to the nasal spine and anterior base of the cartilaginous septum, while secondary cleft septoplasty and adult septoplasty included detachment from the vomer, and ethmoid. In the few reports of cartilage excision during primary cleft septoplasty, removal was limited to the anterior inferior border of the septum, while secondary cleft septoplasty and adult septoplasty included excision of the cartilaginous and bony septum. CONCLUSION Primary cleft septoplasty is distinct from septoplasty performed on facially mature patients. More specifically, septal dissection and detachment are limited to the anterior caudal area during primary lip repair, with rare removal of cartilage or bone. Given these differences, the authors suggest the term "septal reset" to describe septoplasty performed during primary cleft nasal repair.

Abstract
BACKGROUND The long-term effects of nasoalveolar molding (NAM) on patients with bilateral cleft lip and palate (BCLP) are unknown. The authors report clinical outcomes of facially mature patients with complete BCLP who underwent NAM and gingivoperiosteoplasty (GPP). METHODS A single-institution retrospective study of nonsyndromic patients with complete BCLP who underwent NAM between 1991 and 2000 was performed. All study patients were followed to skeletal maturity, at which time a lateral cephalogram was obtained. The total number of cleft operations and cephalometric measures was compared with a previously published external cohort of patients with complete and incomplete BCLP in which a minority (16.7%) underwent presurgical orthopedics before cleft lip repair without GPP. RESULTS Twenty-four patients with BCLP comprised the study cohort. All patients underwent GPP, 13 (54.2%) underwent alveolar bone graft, and nine (37.5%) required speech surgery. The median number of operations per patient was five (interquartile range, two), compared with eight (interquartile range, three) in the external cohort ( P < 0.001). Average age at the time of lateral cephalogram was 18.64 years (1.92). There was no significant difference between our cohort and the external cohort with respect to sella-nasion-point A angle (SNA) [73 degrees (6 degrees) versus 75 degrees (11 degrees); P = 0.186] or sella-nasion-point B angle (SNA) [78 degrees (6 degrees) versus 74 degrees (9 degrees); P = 0.574]. Median ANB (SNA - SNB) was -3 degrees (5 degrees) compared with -1 degree (7 degrees; P = 0.024). Twenty patients (83.3%) underwent orthognathic surgery. CONCLUSION Patients with BCLP who underwent NAM and GPP had significantly fewer total cleft operations and mixed midface growth outcomes at facial maturity compared with patients who did not undergo this treatment protocol. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
The current standard of care for an alveolar cleft defect is an autogenous bone graft, typically from the iliac crest. Given the limitations of alveolar bone graft surgery, such as limited supply, donor site morbidity, graft failure, and need for secondary surgery, there has been growing interest in regenerative medicine strategies to supplement and replace traditional alveolar bone grafts. Though there have been preliminary clinical studies investigating bone tissue engineering methods in human subjects, lack of consistent results as well as limitations in study design make it difficult to determine the efficacy of these interventions. As the field of bone tissue engineering is rapidly advancing, reconstructive surgeons should be aware of the preclinical studies informing these regenerative strategies. We review preclinical studies investigating bone tissue engineering strategies in large animal maxillary or mandibular defects and provide an overview of scaffolds, stem cells, and osteogenic agents applicable to tissue engineering of the alveolar cleft. An electronic search conducted in the PubMed database up to December 2021 resulted in 35 studies for inclusion in our review. Most studies showed increased bone growth with a tissue engineering construct compared to negative control. However, heterogeneity in the length of follow up, method of bone growth analysis, and inconsistent use of positive control groups make comparisons across studies difficult. Future studies should incorporate a pediatric study model specific to alveolar cleft with long-term follow up to fully characterize volumetric defect filling, cellular ingrowth, bone strength, tooth movement, and implant support.

Abstract
OBJECTIVE To define "high osteotomy" and determine the feasibility of performing this procedure. DESIGN Single institution, retrospective review. SETTING Academic tertiary referral hospital. PATIENTS, PARTICIPANTS 34 skeletally mature, nonsyndromic patients with unilateral CLP who underwent Le Fort I osteotomy between 2013 and 2020. Patients with cone-beam computed tomography (CBCT) scans completed both pre- (T1) and post-operatively (T2) were included. Patients with bilateral clefts and rhinoplasty prior to post-operative imaging were excluded. INTERVENTIONS Single jaw one-piece Le Fort I advancement surgery. MAIN OUTCOME MEASURES Measurements of the superior ala and inferior turbinates were taken from the post-operative CBCT. RESULTS The sample included 26 males and 8 females, 12 right- and 22 left-sided clefts. The inferior turbinates are above the superior alar crease at a rate of 73.53% and 76.48% on the cleft and non-cleft sides, respectively. One (2.9%) osteotomy cut was above the level of the cleft superior alar crease, and no cuts were above the level of the non-cleft superior ala. On average, the superior ala was 2.63 mm below the inferior turbinates. The average vertical distances from the superior alar crease and the inferior turbinates to the base of the non-cleft side pyriform aperture were 12.17 mm (95% CI 4.00-20.34) and 14.80 mm (95% CI 4.61-24.98), respectively. To complete a "high osteotomy," with 95% confidence, the cut should be 20.36 mm from the base of the pyriform aperture. CONCLUSIONS A "high" osteotomy is not consistently possible due to the relationship between the superior alar crease and the inferior turbinate.

Abstract
OBJECTIVES Cleft lip repair has traditionally been performed as an inpatient procedure. There has been an interest toward outpatient cleft lip repair to reduce healthcare costs and avoid unnecessary hospital stay. We report surgical outcomes following implementation of an ambulatory cleft lip repair protocol and hypothesize that an ambulatory repair results in comparable safety outcomes to inpatient repair. DESIGN/SETTING This is a single-institution, retrospective study. PATIENTS/PARTICIPANTS Patients undergoing primary unilateral (UCL) and bilateral (BCL) cleft lip repair from 2012 to 2021 with a minimum 30-day follow-up. A total of 226 patients with UCL and 58 patients with BCL were included. INTERVENTION Ambulatory surgery protocol in 2016. OUTCOME MEASURES Variables include demographics and surgical data including 30-day readmission, 30-day reoperation, and postoperative complications. RESULTS There were no differences in rates of 30-day readmission, reoperation, wound complications, or postoperative complications between the pre- and post-protocol groups. Following ambulatory protocol implementation, 80% of the UCL group and 56% of the BCL group received ambulatory surgery. Average length of stay dropped from 24 h pre-protocol to 8 h post-protocol. The 20% of the UCL group and 44% of the BCL group chosen for overnight stay had a significantly higher proportion of congenital abnormalities and higher American Society of Anesthesiology (ASA) class. Reasons for overnight stay included cardiac/airway monitoring, prematurity, and monitoring of comorbidities. There were no differences in surgical outcomes between the ambulatory and overnight stay groups. CONCLUSIONS An ambulatory cleft lip repair protocol can significantly reduce average length of stay without adversely affecting surgical outcomes.

Abstract
OBJECTIVE Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN Cross-sectional survey-based evaluation. SETTING International comprehensive cleft care workshop. PARTICIPANTS Total of 489 participants. INTERVENTIONS Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

Abstract
This case presents a facially mature patient with Beckwith-Wiedemann Syndrome (BWS) who presented with severe class III malocclusion. Computed tomography imaging revealed an anterior crossbite of 19 mm and a narrow pharyngeal airway at the level of the tongue base precluding mandibular setback surgery. The patient was indicated for a LeFort III combined with a LeFort I advancement, each of 10 mm, for a 20 mm combined advancement. Stable, functional occlusion was achieved without airway compromise. This novel use of the combined LeFort III/I can restore stable class I occlusion in patients with BWS at risk for tongue base airway compromise.

Abstract
BACKGROUND Commercial payer-negotiated rates for cleft lip and palate surgery have not been evaluated on a national scale. The aim of this study was to characterize commercial rates for cleft care, both in terms of nationwide variation and in relation to Medicaid rates. METHODS A cross-sectional analysis was performed of 2021 hospital pricing data from Turquoise Health, a data service platform that aggregates hospital price disclosures. The data were queried by CPT code to identify 20 cleft surgical services. Within- and across-hospital ratios were calculated per CPT code to quantify commercial rate variation. Generalized linear models were used to assess the relationship between median commercial rate and facility-level variables and between commercial and Medicaid rates. RESULTS There were 80,710 unique commercial rates from 792 hospitals. Within-hospital ratios for commercial rates ranged from 2.0 to 2.9 and across-hospital ratios ranged from 5.4 to 13.7. Median commercial rates per facility were higher than Medicaid rates for primary cleft lip and palate repair ($5492.20 versus $1739.00), secondary cleft lip and palate repair ($5429.10 versus $1917.00), and cleft rhinoplasty ($6001.00 versus $1917.00; P < 0.001). Lower commercial rates were associated with hospitals that were smaller ( P < 0.001), safety-net ( P < 0.001), and nonprofit ( P < 0.001). Medicaid rate was positively associated with commercial rate ( P < 0.001). CONCLUSIONS Commercial rates for cleft surgical care demonstrated marked variation within and across hospitals, and were lower for small, safety-net, or nonprofit hospitals. Lower Medicaid rates were not associated with higher commercial rates, suggesting that hospitals did not use cost-shifting to compensate for budget shortfalls resulting from poor Medicaid reimbursement.

Abstract
Background In October 2012, an open-access, multimedia digital cleft simulator was released. Its purpose was to address global disparities in cleft surgery education, providing an easily accessible surgical atlas for trainees globally. The simulator platform includes a three-dimensional surgical simulation of cleft care procedures, intraoperative videos, and voiceover. This report aims to assess the simulator's demographics and usage in its tenth year since inception. Finally, we also aim to understand the traction of virtual reality in cleft surgical education. Methods Usage data of the simulator over 10 years were retrospectively collected and analyzed. Data parameters included the number of users, sessions, countries reached, and content access. An electronic survey was emailed to registered users to assess the benefits of the simulator. Results The total number of new and active simulator users reached 7687 and 12,042. The simulator was accessed an average of 172.9.0 ± 197.5 times per month. Low- to middle-income regions accounted for 43% of these sessions. The mean session duration was 11.4 ± 6.3 minutes, yielding a total screen time of 3022 hours. A total of 331 individuals responded to the survey, of whom 80.8% found the simulator to be very useful or extremely useful. Of those involved in education, 45.0% implemented the simulator as a teaching tool. Conclusions Global utilization of the simulator has been sustained after 10 years from inception with an increased presence in low- to middle-income nations. Future similar surgical simulators may provide sustainable training platforms to surgeons in low- and high-resource areas.

Abstract
BACKGROUND Three-dimensional printed bioceramic scaffolds composed of 100% β-tricalcium phosphate augmented with dipyridamole (3DPBC-DIPY) can regenerate bone across critically sized defects in skeletally mature and immature animal models. Before human application, safe and effective bone formation should be demonstrated in a large translational animal model. This study evaluated the ability of 3DPBC-DIPY scaffolds to restore critically sized calvarial defects in a skeletally immature, growing minipig. METHODS Unilateral calvarial defects (~1.4 cm) were created in 6-week-old Göttingen minipigs ( n = 12). Four defects were filled with a 1000 μm 3DPBC-DIPY scaffold with a cap (a solid barrier on the ectocortical side of the scaffold to prevent soft-tissue infiltration), four defects were filled with a 1000 μm 3DPBC-DIPY scaffold without a cap, and four defects served as negative controls (no scaffold). Animals were euthanized 12 weeks postoperatively. Calvariae were subjected to micro-computed tomography, 3D reconstruction with volumetric analysis, qualitative histologic analysis, and nanoindentation. RESULTS Scaffold-induced bone growth was statistically greater than in negative controls ( P ≤ 0.001), and the scaffolds with caps produced significantly more bone generation compared with the scaffolds without caps ( P ≤ 0.001). Histologic analysis revealed woven and lamellar bone with haversian canals throughout the regenerated bone. Cranial sutures were observed to be patent, and there was no evidence of ectopic bone formation or excess inflammatory response. Reduced elastic modulus and hardness of scaffold-regenerated bone were found to be statistically equivalent to native bone ( P = 0.148 for reduced elastic modulus of scaffolds with and without caps and P = 0.228 and P = 0.902 for hardness of scaffolds with and without caps, respectively). CONCLUSION 3DPBC-DIPY scaffolds have the capacity to regenerate bone across critically sized calvarial defects in a skeletally immature translational pig model. CLINICAL RELEVANCE STATEMENT This study assessed the bone generative capacity of 3D-printed bioceramic scaffolds composed of 100% β-tricalcium phosphate and augmented with dipyridamole placed within critical-sized calvarial defects in a growing porcine model.

Abstract
Defects characterized as large osseous voids in bone, in certain circumstances, are difficult to treat, requiring extensive treatments which lead to an increased financial burden, pain, and prolonged hospital stays. Grafts exist to aid in bone tissue regeneration (BTR), among which ceramic-based grafts have become increasingly popular due to their biocompatibility and resorbability. BTR using bioceramic materials such as β-tricalcium phosphate has seen tremendous progress and has been extensively used in the fabrication of biomimetic scaffolds through the three-dimensional printing (3DP) workflow. 3DP has hence revolutionized BTR by offering unparalleled potential for the creation of complex, patient, and anatomic location-specific structures. More importantly, it has enabled the production of biomimetic scaffolds with porous structures that mimic the natural extracellular matrix while allowing for cell growth-a critical factor in determining the overall success of the BTR modality. While the concept of 3DP bioceramic bone tissue scaffolds for human applications is nascent, numerous studies have highlighted its potential in restoring both form and function of critically sized defects in a wide variety of translational models. In this review, we summarize these recent advancements and present a review of the engineering principles and methodologies that are vital for using 3DP technology for craniomaxillofacial reconstructive applications. Moreover, we highlight future advances in the field of dynamic 3D printed constructs via shape-memory effect, and comment on pharmacological manipulation and bioactive molecules required to treat a wider range of boney defects.

Abstract
INTRODUCTION Treacher Collins syndrome is a rare congenital disease characterized by the multiple craniofacial malformations. Although the deformities affecting patients with Treacher Collins syndrome have been well characterized, the effects of these malformations to clinical severity of the syndrome are not well understood. OBJECTIVE To determine the association of specific Treacher Collins mandibular malformations with clinical severity. DESIGN A retrospective radiographic observational study. SETTING Study conducted at a single institution, a quaternary craniofacial care center. PATIENTS 54 patients with Treacher Collins syndrome. INTERVENTIONS Computed tomography (CT), clinical photographs and medical history were included in this analysis. Mandibles were isolated from CT data and reconstructed in three dimensions using Mimics software. Cephalometric measurements were performed on CT data. Clinical severity was determined by Teber and Vincent scores. Association of craniofacial dysmorphology to clinical severity was determined by Spearman rank coefficient. MAIN OUTCOME MEASURES The main results obtained were the measurements of the mandibles and the quantification of the malformations of the evaluated patients. RESULTS Among the most frequent findings in the sample are hypoplasia of the zygomatic complex, descending palpebral cleft and mandibular hypoplasia. Patients with a lower ramus/corpus ratio had a higher (more severe) Teber and Vincent classification. CONCLUSION Patients with the most compromised mandible are also the patients with the highest number of malformations, thus, the most severe patients.

Abstract
OBJECTIVE The purpose of this study is to assess cleft rhinoplasty terminology across phases of growth.Design/Setting: A systematic review was performed on cleft rhinoplasty publications over 20 years.Interventions: Studies were categorized by age at surgical intervention: infant (<1 year); immature (1 to 14 years); mature (>15 years).Main Outcome Measures: Collected data included terminology used and surgical techniques. RESULTS The 288 studies included demonstrated a wide range of terminology. In the infant group, 51/54 studies used the term "primary." In the immature group, 7/18 studies used the term "primary," 3/18 used "secondary." In the mature group, 2/33 studies used the term "primary," 16/33 used "secondary," 2/33 used "definitive," 5/33 used terms such as "mature," "adult," and "late," and 8/33 did not use terminology.Surgical technique assessment demonstrated: cleft rhinoplasty at infancy used nostril rim or no nasal incision, immature rhinoplasty used closed and open rhinoplasty incisions; and mature rhinoplasty used a majority of open rhinoplasty. Infant and immature cleft rhinoplasty incorporated septal harvest or spur removal in <10% of cases, whereas these procedures were common in mature rhinoplasty. No studies in infants or immature patients used osteotomies or septal grafts, common techniques in mature rhinoplasty. CONCLUSIONS Current terminology for cleft rhinoplasty is varied and inconsistently applied across stages of facial development. However, cleft rhinoplasty performed at infancy, childhood, and facial maturity are surgically distinct procedures. The authors recommend the terminology "infant," "immature," and "mature" cleft rhinoplasty to accurately describe this procedure within the context of skeletal growth.

Abstract
Lambdoid craniosynostosis (CS) is a congenital anomaly resulting from premature fusion of the cranial suture between the parietal and occipital bones. Predominantly sporadic, it is the rarest form of CS and its genetic etiology is largely unexplored. Exome sequencing of 25 kindreds, including 18 parent-offspring trios with sporadic lambdoid CS, revealed a marked excess of damaging (predominantly missense) de novo mutations that account for ~ 40% of sporadic cases. These mutations clustered in the BMP signaling cascade (P = 1.6 × 10-7), including mutations in genes encoding BMP receptors (ACVRL1 and ACVR2A), transcription factors (SOX11, FOXO1) and a transcriptional co-repressor (IFRD1), none of which have been implicated in other forms of CS. These missense mutations are at residues critical for substrate or target sequence recognition and many are inferred to cause genetic gain-of-function. Additionally, mutations in transcription factor NFIX were implicated in syndromic craniosynostosis affecting diverse sutures. Single cell RNA sequencing analysis of the mouse lambdoid suture identified enrichment of mutations in osteoblast precursors (P = 1.6 × 10-6), implicating perturbations in the balance between proliferation and differentiation of osteoprogenitor cells in lambdoid CS. The results contribute to the growing knowledge of the genetics of CS, have implications for genetic counseling, and further elucidate the molecular etiology of premature suture fusion.

Abstract
BACKGROUND β-Tricalcium phosphate (β-TCP) is one of the most common synthetic bone grafting materials utilized in craniofacial reconstruction; however, it is limited by a slow degradation rate. The aim of this study was to leverage 3-dimensional (3D) printing in an effort to accelerate the degradation kinetics of β-TCP. METHODS Twenty-two 1-month-old New Zealand white rabbits underwent creation of calvarial and alveolar defects, repaired with 3D-printed β-TCP scaffolds coated with 1000 μM of osteogenic agent dipyridamole. Rabbits were euthanized after 2, 6, and 18 months after surgical intervention. Bone regeneration, scaffold degradation, and bone mechanical properties were quantified. RESULTS Histological analysis confirmed the generation of vascularized and organized bone. Microcomputed tomography analysis from 2 to 18 months demonstrated decreased scaffold volume within calvarial (23.6% ± 2.5%, 5.1% ± 2.2%; P < 0.001) and alveolar (21.5% ± 2.2%, 0.2% ± 1.9%; P < 0.001) defects, with degradation rates of 54.6%/year and 90.5%/year, respectively. Scaffold-inducted bone generation within the defect was volumetrically similar to native bone in the calvarium (55.7% ± 6.9% vs 46.7% ± 6.8%; P = 0.064) and alveolus (31.4% ± 7.1% vs 33.8% ± 3.7%; P = 0.337). Mechanical properties between regenerated and native bone were similar. CONCLUSIONS Our study demonstrates an improved degradation profile and replacement of absorbed β-TCP with vascularized, organized bone through 3D printing and addition of an osteogenic agent. This novel additive manufacturing and tissue engineering protocol has implications to the future of craniofacial skeletal reconstruction as a safe and efficacious bone tissue engineering method.

Abstract
Robin sequence (RS) is diagnosed in infants born with micrognathia, glossoptosis and varying degrees of upper airway obstruction (UAO). Due to the variable levels of hypoxia, severe breathing and feeding problems can occur. Treatment is determined by clinical severity, ranging from conservative interventions for mild cases to surgical interventions for severe cases. Mandibular distraction osteogenesis (MDO) is a surgical technique that gradually lengthens the mandible after an osteotomy by using an internal or external distraction device, directly correcting the micrognathia. This review will focus on advantages and disadvantages of mandibular distraction in infants with RS.

Abstract
Skeletal conditions represent a considerable challenge to health systems globally. Barriers to effective therapeutic development include a lack of accurate preclinical tissue and disease models. Most recently, work was attempted to present a novel whole organ approach to modeling human bone and cartilage tissues. These self-assembling skeletal organoids mimic the cellular milieu and extracellular organization present in native tissues. Bone organoids demonstrated osteogenesis and micro vessel formation, and cartilage organoids showed evidence of cartilage development and maturation. Skeletal organoids derived from both bone and cartilage tissues yielded spontaneous polarization of their cartilaginous and bone components. Using these hybrid skeletal organoids, we successfully generated "mini joint" cultures, which we used to model inflammatory disease and test Adenosine (A2A ) receptor agonists as a therapeutic agent. The work and respective results indicated that skeletal organoids can be an effective biological model for tissue development and disease as well as to test therapeutic agents.

Abstract
The double Frost suture is a useful supplement to the reconstruction of ipsilateral upper and lower eyelid defects with full-thickness skin grafts. This technique involves silk traction sutures that overlap the upper and lower eyelids to place them on maximal stretch after placement of 2 full-thickness skin grafts. It has the added benefit of protecting the cornea and compressing both grafts under 1 bolster. The authors illustrate this technique in 2 pediatric cases-a congenital melanocytic kissing eyelid nevus and a periocular burn. Each case resulted in large upper and lower anterior lamellar defects, which were reconstructed with supraclavicular and retroauricular free skin grafts. The double Frost sutures counter vertical cicatricial forces during graft healing, obviating the need for staged procedures. Both described cases resulted in excellent graft survival with minimal contracture.

Abstract
INTRODUCTION We analyzed the perceptions of participants and faculty members in simulation-based comprehensive cleft care workshops regarding comprehensive cleft care delivery in developing countries. METHODS Data were collected from participants and faculty members in 2 simulation-based comprehensive cleft care workshops organized by Global Smile Foundation. We collected demographic data and surveyed what they believed was the most significant barrier to comprehensive cleft care delivery and the most important intervention to deliver comprehensive cleft care in developing countries. We also compared participant and faculty responses. RESULTS The total number of participants and faculty members was 313 from 44 countries. The response rate was 57.8%. The majority reported that the most significant barrier facing the delivery of comprehensive cleft care in developing countries was financial (35.0%), followed by the absence of multidisciplinary cleft teams (30.8%). The majority reported that the most important intervention to deliver comprehensive cleft care was creating multidisciplinary cleft teams (32.2%), followed by providing cleft training (22.6%). We found no significant differences in what participants and faculty perceived as the greatest barrier to comprehensive cleft care delivery (P = 0.46), or most important intervention to deliver comprehensive cleft care in developing countries (P = 0.38). CONCLUSIONS Our study provides an appraisal of barriers facing comprehensive cleft care delivery and interventions required to overcome these barriers in developing countries. Future studies will be critical to validate or refute our findings, as well as determine country-specific roadmaps for delivering comprehensive cleft care to those who need it the most.

Abstract
OBJECTIVE Utilize 3-dimensional (3D) photography to evaluate the nasolabial changes in infants with bilateral cleft lip and palate (BCLP) who underwent nasoalveolar molding (NAM) and primary reconstructive surgery. DESIGN This is a retrospective serial longitudinal study of consecutively enrolled infants from September 2012 to July 2016 with BCLP who underwent NAM before primary lip and nose reconstructive surgery. It included infants who had digital 3dMD stereophotogrammetry records at initial presentation (T1), completion of NAM (T2), and 3 weeks following primary repair (T3). Twelve infants fulfilled the inclusion criteria. 3dMD Vultus software was used to orient images and plot 16 nasolabial points with x, y, z coordinates to obtain the linear and angular measurements. Nasal form changes were measured and analyzed between T1 (0.5 months old), T2 (5 months old), and T3 (6 months old). Intraclass correlation coefficient was performed for intrarater reliability. Averaged data from the 3D images was statistically analyzed from T1 to T2 and T2 to T3 with Wilcoxon tests. Unaffected infant norms from the Farkas publication were used as a control sample. RESULTS After NAM therapy, statistically significant changes in the position of subnasale and labius superius improved nasolabial symmetry. Both retruded after NAM were displaced downward after NAM and surgical correction with respect to soft tissue nasion. The nasal tip's projection was maintained with NAM and surgical correction. The columella lengthened from 1.4 to 4.71 mm following NAM. CONCLUSIONS There was a significant improvement in the nasolabial anatomy after NAM, and this was further enhanced after primary reconstructive surgery.

Abstract
PURPOSE The purpose of this study was to measure the association between the magnitude of advancement and dental and skeletal relapse in patients with cleft lip and palate (CLP). METHODS A single-institution retrospective cohort study of skeletally matured patients with CLP who underwent isolated Le Fort I advancement surgery between 2013 and 2019 was studied. Patients were included if they had lateral cephalograms or cone-beam computed tomography (CBCT) at preoperative (T1), immediately postoperative (T2), and 1-year follow-up (T3). Lateral cephalometric landmarks were digitized and measured. The sample was divided on the basis of the magnitude of skeletal advancement: minor (<5 mm), moderate (≥5 but <10 mm), and major (≥10 mm) advancement groups. The mean advancement and relapse were compared between groups using 1-way ANOVA. Correlation between the amount of surgical advancement and relapse was evaluated. RESULTS Forty-nine patients with nonsyndromic CLP with hypoplastic maxilla met inclusion criteria and the sample consisted of 36 males and 13 females with the mean age of 19.5 years. In the minor, moderate, and major advancement groups, the mean advancement at point A was +4.1 ± 0.4, + 7.5 ± 1.4, and +11.3 ± 1.3 mm, respectively. At 1-year follow-up, the mean relapse at point A was -1.3 ± 1.2, -1.1 ± 1.2, and -1.7 ± 1.5 mm, respectively. There was no significant difference in the relapse amount between all surgical groups. No correlation between the magnitude of advancement and relapse was found. CONCLUSIONS This study demonstrated no statistically significant difference in skeletal stability between a minor (<5 mm), moderate (≥5 but <10 mm), and major (≥10 mm) Le Fort I advancement groups in patients with clefts. Regardless of the degree of advancement, mild skeletal relapse was observed in all 3 groups.

Abstract
The Le Fort III advancement was first described in 1950 and has since become a key technique in the armamentarium of craniofacial surgeons. The application of distraction osteogenesis to the craniofacial skeleton has allowed for large movements to be performed safely in young patients. This technique is valuable for correcting exorbitism, airway obstruction owing to midface retrusion, and class III malocclusion. It can be performed with either an external distractor or internal distractors. Although serious complications have been reported, these occur rarely when performed by experienced providers.

Abstract
Pierre Robin sequence is defined by the clinical triad: mandibular hypoplasia, glossoptosis, and airway obstruction. Mandibular distraction osteogenesis (MDO) is a standard treatment of Robin sequence associated with severe airway obstruction and is the only intervention that directly corrects the underlying anatomic pathologic condition. Compared with tongue-lip adhesion, MDO has demonstrated more success in treating airway obstruction in infants with Pierre Robin sequence, including patients with syndromic diagnoses and concomitant anomalies. This article provides a current, comprehensive review of neonatal mandibular distraction and offers treatment guidelines based on a combined surgical experience of more than 400 patients.

Abstract
STUDY OBJECTIVES Identifying optimal treatment for infants with Robin sequence (RS) is challenging due to substantial variability in the presentation of upper airway obstruction (UAO) in this population. Objective assessments of UAO and treatments are not standardized. A systematic review of objective measures of UAO was conducted as step towards evidence based clinical decision making for RS. METHODS A literature search was performed in Pubmed and Embase databases (1990-2020) following PRISMA-guidelines. Articles reporting on RS and UAO-treatment were included if the following objective measures were studied: oximetry, polysomnography and blood gas. Quality was appraised by methodological index for non-randomized studies (MINORS, range:0-24). RESULTS A total of 91 articles met inclusion criteria. Mean MINORS-score was 7.1 (range:3-14). Polysomnography was most frequently used (76%) followed by oximetry (20%) and blood gas (11%). Sleep position of the infant was reported in 35% of studies, with supine position most frequently, and monitoring time in 42%, including overnight recordings in more than half. Of 71 studies that evaluated UAO-interventions, the majority used polysomnography (90%), of which 61% did not specify the polysomnography technique. Reported polysomnography metrics included oxygen saturation (61%), apnea-hypopnea index (52%), carbon dioxide levels (31%), obstructive-apnea-hypopnea index (27%), and oxygen-desaturation-index (16%). Only 42 studies reported indications for UAO-intervention, with oximetry and polysomnography thresholds used equally (both 40%). In total, 34 distinct indications for treatment were identified. CONCLUSIONS This systematic review demonstrates a lack of standardization, interpretation and reporting of assessment and treatment indications for UAO in RS. An international, multidisciplinary consensus protocol is needed to guide clinicians on optimal UAO assessment in RS.

Abstract
OBJECTIVE This study evaluates skeletal and dental outcomes of LeFort I advancement surgery in patients with cleft lip and palate (CLP) with varying degrees of maxillary skeletal hypoplasia. DESIGN Retrospective study. METHOD Lateral cephalograms were digitized at preoperative (T1), immediately postoperative (T2), and 1-year follow-up (T3) and compared to untreated unaffected controls. Based on the severity of cleft maxillary hypoplasia, the sample was divided into 3 groups using Wits analysis: mild: ≤0 to ≥-5 mm; moderate: <-5 to >-10 mm; and severe: ≤-10 mm. PARTICIPANTS Fifty-one patients with nonsyndromic CLP with hypoplastic maxilla who met inclusion criteria. INTERVENTION LeFort I advancement. MAIN OUTCOME MEASURE Skeletal and dental stability post-LeFort I surgery at a 1-year follow-up. RESULTS At T2, LeFort I surgery produced an average correction of maxillary hypoplasia by 6.4 ± 0.6, 8.1 ± 0.4, and 10.7 ± 0.8 mm in the mild, moderate, and severe groups, respectively. There was a mean relapse of 1 to 1.5 mm observed in all groups. At T3, no statistically significant differences were observed between the surgical groups and controls at angle Sella, Nasion, A point (SNA), A point, Nasion, B point (ANB), and overjet outcome measures. CONCLUSIONS LeFort I advancement produces a stable correction in mild, moderate, and severe skeletal maxillary hypoplasia. Overcorrection is recommended in all patients with CLP to compensate for the expected postsurgical skeletal relapse.

Abstract
INTRODUCTION Nasal duplication is a rare congenital deformity with many subtypes including supernumerary nostril. The challenge of surgical correction is to achieve nasal symmetry and restore nasal airflow. However, there is no defined protocol for treatment, especially with regard to presurgical therapy. METHODS We performed a review of literature of studies reporting on patients with supernumerary nostril to complete this review. We then report on a patient with supernumerary nostril who was treated with nostril expansion therapy prior to surgical intervention. RESULTS We identified 59 cases of nostril duplication. Because of the rarity of the condition, treatment protocols varied greatly. For our patient, preoperative nasal appliance therapy was implemented for 3 months prior to surgical intervention. Patient was followed-up regularly for 1 year. DISCUSSION Although literature on nasal duplication is scarce, there is a general agreement that early intervention has psychological, anatomic, and functional benefits to the patient. In our case report, nostril expansion therapy was easy to implement and facilitated surgical reconstruction, resulting in aesthetic outcome and expanded airway 1 year postoperatively.

Abstract
The basic concepts from the fields of biology and engineering are integrated into tissue engineering to develop constructs for the repair of damaged and/or absent tissues, respectively. The field has grown substantially over the past two decades, with particular interest in bone tissue engineering (BTE). Clinically, there are circumstances in which the quantity of bone that is necessary to restore form and function either exceeds the patient's healing capacity or bone's intrinsic regenerative capabilities. Vascularized osseous or osteocutaneous free flaps are the standard of care with autologous bone remaining the gold standard, but is commonly associated with donor site morbidity, graft resorption, increased operating time, and cost. Regardless of the size of a craniofacial defect, from trauma, pathology, and osteonecrosis, surgeons and engineers involved with reconstruction need to consider the complex three-dimensional (3D) geometry of the defect and its relationship to local structures. Three-dimensional printing has garnered significant attention and presents opportunities to use craniofacial BTE as a technology that offers a personalized approach to bony reconstruction. Clinicians and engineers are able to work together to produce patient-specific space-maintaining scaffolds tailored to site-specific defects, which are osteogenic, osseoconductive, osseoinductive, encourage angiogenesis/vasculogenesis, and mechanically stable upon implantation to prevent immediate failure. In this work, we review biological and engineering principles important in applying 3D printing technology to BTE for craniofacial reconstruction as well as present recent translational advancements in 3D printed bioactive ceramic scaffold technology.

Abstract
BACKGROUND The aim of this study is to assess the effect of nasoalveolar molding (NAM) versus no-NAM on nasal morphology in patients with unilateral cleft lip and palate (UCLP) at the time of nasal maturity. METHODS A retrospective, single-institution review was conducted on all non-syndromic patients with UCLP. Inclusion criteria included age 14 years or above, unilateral cleft repair at the time of infancy, and adequate photography taken at nasal maturity and prior to rhinoplasty. Exclusion criteria included age less than 14 years, syndromic diagnosis, and rhinoplasty prior to nasal maturity. Ten parameters were measured twice from standardized clinical photographs using the Dolphin Imaging Software for establishment of intrarater reliability. Subjective analysis was achieved through completion of the Asher McDade grading scale by 3 expert cleft practitioners. RESULTS Nostril height, columellar angle, alar cant, vertical alar height, alar height angle, nasofacial angle, and nasolabial angle were found to be significantly less severe in patients who had undergone NAM in conjunction with surgical repair when compared with those who had undergone surgical repair alone. Asher McDade grading revealed significant improvement in nasal form, nasal symmetry/deviation, nasal profile, vermillion border, and overall score in patients who underwent NAM compared to no-NAM. CONCLUSION The use of presurgical NAM during infancy can improve nasal symmetry and nasal proportions at the time of nasal maturity.

Abstract
OBJECTIVE Evaluate simulation-based comprehensive cleft care workshops as a reproducible model for education with sustained impact. DESIGN Cross-sectional survey-based evaluation. SETTING Simulation-based comprehensive cleft care workshop. PARTICIPANTS Total of 180 participants. INTERVENTIONS Three-day simulation-based comprehensive cleft care workshop. MAIN OUTCOME MEASURES Number of workshop participants stratified by specialty, satisfaction with the workshop, satisfaction with simulation-based workshops as educational tools, impact on cleft surgery procedural confidence, short-term impact on clinical practice, medium-term impact on clinical practice. RESULTS The workshop included 180 participants from 5 continents. The response rate was 54.5%, with participants reporting high satisfaction with all aspects of the workshop and with simulation-based workshops as educational tools. Participants reported a significant improvement in cleft lip (33.3 ± 5.7 vs 25.7 ± 7.6; P < .001) and palate (32.4 ± 7.1 vs 23.7 ± 6.6; P < .001) surgery procedural confidence following the simulation sessions. Participants also reported a positive short-term and medium-term impact on their clinical practices. CONCLUSION Simulation-based comprehensive cleft care workshops are well received by participants, lead to improved cleft surgery procedural confidence, and have a sustained positive impact on participants' clinical practices. Future efforts should focus on evaluating and quantifying this perceived positive impact, as well reproducing these efforts in other areas of need.

Abstract
OBJECTIVE This systematic review aims to evaluate nasoalveolar molding (NAM) in the context of burden of care defined as physical, psychosocial, or financial burden on caregivers. SEARCH METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 5 databases were searched from inception through December 24, 2019, for keywords and subject headings pertaining to cleft lip and/or palate and NAM. ELIGIBILITY CRITERIA Clinical studies on NAM with reference to physical (access to care, number of visits, distance traveled), psychosocial (caregiver perceptions, family interactions, breast milk feeding), and financial (direct and indirect costs) burden were included. DATA COLLECTION AND ANALYSIS Study selection was performed by 2 independent reviewers. RESULTS The search identified 1107 articles and 114 articles remained for qualitative synthesis. Burden of care domains were discussed but not measured in 43% of articles and only 25% assessed burden of care through a primary outcome. Of these, 20 articles reported on physical, 8 articles on psychosocial, and 12 articles on financial burden. Quality of evidence is limited by study design and risk of bias. CONCLUSION Nasoalveolar molding has been indiscriminately associated with burden of care in the literature. Although NAM may not be the ideal treatment option for all patients and families, the physical considerations are limited when accounting for the observed psychosocial advantages. Financial burden appears to be offset, but further research is required. Teams should directly assess the impact of this early intervention on the well-being of caregivers and advance strategies that improve access to care.

Abstract
This study investigates a comprehensive model of bone regeneration capacity of dypiridamole-loaded 3D-printed bioceramic (DIPY-3DPBC) scaffolds composed of 100% beta-tricalcium phosphate (β -TCP) in an immature rabbit model through the time of facial maturity. The efficacy of this construct was compared to autologous bone graft, the clinical standard of care in pediatric craniofacial reconstruction, with attention paid to volume of regenerated bone by 3D reconstruction, histologic and mechanical properties of regenerated bone, and long-term safety regarding potential craniofacial growth restriction. Additionally, long-term degradation of scaffold constructs was evaluated. At 24 weeks in vivo, DIPY-3DPBC scaffolds demonstrated volumetrically significant osteogenic regeneration of calvarial and alveolar defects comparable to autogenous bone graft with favorable biodegradation of the bioactive ceramic component in vivo. Characterization of regenerated bone reveals osteogenesis of organized, vascularized bone with histologic and mechanical characteristics comparable to native bone. Radiographic and histologic analyses were consistent with patent craniofacial sutures. Lastly, through application of 3D morphometric facial surface analysis, our results support that DIPY-3DPBC scaffolds do not cause premature closure of sutures and preserve normal craniofacial growth. Based on this novel evaluation model, this DIPY-3DPBC scaffold strategy is a promising candidate as a safe, efficacious pediatric bone tissue engineering strategy.

Abstract
A number of digital and haptic simulators have been developed to address challenges facing cleft surgery education. However, to date, a comprehensive review of available simulators has yet to be performed. Our goal is to appraise cleft surgery simulators that have been described to date, their role within a simulation-based educational strategy, the costs associated with their use, and data supporting or refuting their utility.

Abstract
OBJECTIVE Informed decision-making relies on available information, including online resources. We evaluated the content and readability of websites published by American Cleft Palate-Craniofacial Association (ACPA)-approved cleft lip and/or palate (CLP) teams in the United States. DESIGN Team websites were reviewed, and teams with no accessible website or <30 sentences of content were excluded. Website content was scored by presence/absence of 20 variables derived from ACPA approval standards. Readability was evaluated with 8 scales. Readability was then compared to American Medical Association (AMA) recommendations. The relationship between website content and readability was assessed. MAIN OUTCOME MEASURE(S) Content and readability of team websites. RESULTS From 167 reviewed teams, 47 (28.1%) had nonfunctional links, 17 (10.2%) had no accessible website, and 39 (23.4%) had <30 sentences. The average content score for all 111 team websites included was 14.5 (2.6) of 20. The combined average reading level across all scales (10.7 [1.9]) exceeded the AMA-recommended sixth-grade reading level; this finding held true for each individual website. Children's Hospital-affiliated teams (n = 86) had a significantly higher content score (14.8 vs 13.5; P = .03) and better readability as evidenced by lower reading grade level (10.5 vs 11.4; P = .04). On linear regression, a higher content score significantly predicted better readability (β = -0.226; P < .001). CONCLUSIONS Websites published by ACPA-approved CLP teams vary in accessibility and content and exceed the recommended reading level. These findings could inform future efforts to improve patient-oriented resources.

Abstract
OBJECTIVE Assess the weight and contribution of each of the parameters of the Asher-McDade Scale to overall subjective assessment of nasolabial aesthetics following cleft lip repair. DESIGN Retrospective cohort evaluation. SETTING Cleft and craniofacial center. PARTICIPANTS Forty-one patients who underwent unilateral cleft lip repair. INTERVENTIONS Unilateral cleft lip repair. MAIN OUTCOME MEASURES Nasolabial rating using the Asher-McDade scale and overall subjective assessment of nasolabial aesthetics using a rank score following unilateral cleft lip repair. RESULTS Strong interrater reliability was observed between the 3 raters. Significant association was determined on bivariate analysis between nasal form score (β = 27.06; P < .001), nasal symmetry score (β = 26.41; P < .001), nasal profile score (β = 28.75; P < .001), vermilion border score (β = 13.40; P = .012), and the ranking score. Adjusted β coefficients obtained from multivariate regression analysis were used to develop a modified nasolabial appearance score (over 5), that is, weighted for each of the 4 parameters: nasal form (over 8, adjusted β = 14.33), nasal symmetry (over 5, adjusted β = 7.96), nasal profile (over 5, adjusted β = 9.44), and vermilion (over 2, adjusted β = 3.31). Regression analysis between our modified nasolabial appearance score and patient ranking score demonstrated superior goodness of fit when compared to the Asher-McDade overall nasolabial appearance score (R2 = .80; P < .001 vs R2 = .69; P < .001). CONCLUSION The parameters evaluated in the Asher-McDade scale have different weights and contribute differently to overall subjective assessment of nasolabial aesthetic outcomes following cleft lip repair. Adjusting for their weights results in a modified score that demonstrates superior correlation with overall subjective assessment of nasolabial aesthetic outcomes.

Abstract
BACKGROUND Rhinoplasty relies on clear patient communication and precise execution of a three-dimensional (3D) plan to achieve optimal results. As 3D imaging and printing continue to grow in popularity within the medical field, rhinoplasty surgeons have begun to leverage these resources as an aid to preoperative planning, patient communication, and the technical performance of this challenging operation. OBJECTIVES Utilizing departmentally available resources and open-access 3D imaging platforms, we have developed an affordable, reproducible protocol for rapid in-house virtual surgical planning (VSP) and subsequent manufacture of 3D-printed rhinoplasty models. METHODS Preoperative 3D photographic images underwent virtual rhinoplasty using a freely available 3D imaging and sculpting program (BlenderTM [Version 2.78, Amsterdam, The Netherlands]). Once the ideal postoperative result was digitally achieved, scaled, sterilizable, and patient-specific 3D models of the preoperative and ideal postoperative result were manufactured in-house using a departmentally owned 3D printer. RESULTS 3D-printed models have successfully been manufactured and employed for 12 patients undergoing rhinoplasty. The average time to prepare a set of pre- and postoperative models was 3 hours, while the printing process required 18 to 24 hours per model. Each set of surgical models can be manufactured at a total materials cost of approximately $5.00. CONCLUSIONS We describe an affordable means to construct sterilizable, scaled, patient-specific 3D-printed models for rhinoplasty. This technique may become of increasing interest to academic and cosmetic centers as hardware costs of 3D printers continue to fall. LEVEL OF EVIDENCE: 4
