Surgical Tray Optimization in the Setting of Cleft Lip and Palate Reconstruction: Implications for Operative Cost and Efficiency.

OBJECTIVES: To assess surgical instrument usage in cleft lip (CL) and cleft palate (CP) surgery and create an optimized surgical tray with an associated cost-savings analysis. DESIGN: Prospective, observational study. SETTING: Single institution, 6-month prospective review. PATIENTS/PARTICIPANTS: A total of 10 primary CL surgeries and 10 primary CP surgeries were included in this study. INTERVENTION: Complete lists of surgical instruments utilized in CL and CP surgeries were collected.Utilization fractions (UFs) were calculated as the percentages of average used instruments to averaged opened instruments per case. New optimized CL and CP surgical trays were idealized by removing instruments not used in at least 20% of cases, and a cost analysis was performed to identify potential savings. Calculation of annual potential savings was also conducted based on institutional caseload. RESULTS: The average instrument UFs were 26.0% for CL and 22.6% for CP. The estimated costs were $33.15 to $290.29 for the original CL surgical tray and $10.20 to $63.80 for the optimized tray. For CP, the original tray's cost was estimated at $38.25 to $319.00, and the optimized tray at $9.18 to $57.42. This demonstrates a cost reduction of $22.95 to $226.49 for CL and $29.07 to 261.58 for CP. CONCLUSIONS: The idealized surgical instrument tray could contribute to reducing healthcare expenditures and promoting operating room efficiency, patient safety, and environmentally friendlier operating theaters.

Combined Whole Eye and Face Transplant: Microsurgical Strategy and 1-Year Clinical Course.

Importance: Catastrophic facial injury with globe loss remains a formidable clinical problem with no previous reports of reconstruction by whole eye or combined whole eye and facial transplant. Objective: To develop a microsurgical strategy for combined whole eye and facial transplant and describe the clinical findings during the first year following transplant. Design, Setting, and Participant: A 46-year-old man who sustained a high-voltage electrical injury with catastrophic tissue loss to his face and left globe underwent combined whole eye and face transplant using personalized surgical devices and a novel microsurgical strategy at a specialized center for vascularized composite allotransplantation. Main Outcomes and Measures: Reperfusion and viability of the whole eye and facial allografts, retinal function, and incidence of acute rejection. Results: The patient underwent a combined whole eye and face transplant from an immunologically compatible donor with primary optic nerve coaptation and conventional postoperative immunosuppression. Globe and retinal perfusion were maintained throughout the immediate postoperative period, evidenced by fluorescein angiography. Optical coherence tomography demonstrated atrophy of inner retinal layers and attenuation and disruption of the ellipsoid zone. Serial electroretinography confirmed retinal responses to light in the transplanted eye. Using structural and functional magnetic resonance imaging, the integrity of the transplanted visual pathways and potential occipital cortical response to light stimulation of the transplanted eye was demonstrated. At 1 year post transplant (postoperative day 366), there was no perception of light in the transplanted eye. Conclusions and Relevance: This is the first report of whole eye transplant combined with facial transplant, demonstrating allograft survival including rejection-free graft survival and electroretinographic measurements indicating retinal response to light stimuli. These data highlight the potential for clinical allotransplantation for globe loss.

Risk Factors for Acute-Level Hospital Course in Pediatric Craniofacial Fractures.

PURPOSE: The pediatric craniofacial trauma literature is limited to single institutions or short study periods. Herein, this study analyzes a national database over 10 years to delineate the epidemiology of pediatric craniofacial fractures and to identify risk factors for acute-level hospital course in the largest series to date. METHODS: Utilizing the National Trauma Data Bank, pediatric craniofacial fractures admitted between 2010 and 2019 were identified. Descriptive analyses and multivariable regression were performed to identify risk factors for acute-level hospital course. RESULTS: A total of 155,136 pediatric craniofacial fracture cases were reviewed, including cranial vault (49.0%), nasal (22.4%), midface (21.0%), mandibular (20.2%), and orbital floor fractures (13.7%). Midface and orbital floor fractures occurred commonly as multicraniofacial fractures. Cranial vault fractures were the most common among all age groups, but frequency declined with age. In contrast, facial fractures increased with age. Despite the inherent complexity of multicraniofacial trauma, isolated fractures remained a concern for acute-level hospital course.Cranial vault and midface fractures had an increased risk of intracranial injury and intensive care unit admission (P<0.001). Mandibular and midface fractures had an increased risk for cervical spine fracture and tracheostomy (P<0.001). Patient and injury-specific risk factors among the fractures with the strongest association for each outcome-cranial vault and mandible-were identified. CONCLUSIONS: The inherent limitations of prior studies-geographical biases, small cohorts, and short-term study periods-were addressed. Describing the independent contribution of each craniofacial fracture to the risk of acute-level hospital course outcomes can be employed to better optimize risk stratification, counseling, and management.

Comparison of the Effects of Postoperative Arm Restraints and Mittens on Cleft Lip Scar Quality after Primary Repair.

Introduction: Postoperative management following primary cleft lip repair varies across institutions, cleft care teams, and individual surgeons. Postoperative precautions employed after cleft lip repair include dietary restrictions, pacifier limitations, and immobilization, with arm restraints long being used. Yet, restraint distress has led to the exploration of other forms of immobilization. Thus, this study aims to assess cleft lip scar quality and complication rates after postoperative immobilization with arm restraints versus hand mittens. Methods: A retrospective review of patients with unilateral cleft who underwent primary repair with the senior surgeon was done. Data on demographics, surgical characteristics, and immobilization utilized were gathered. A survey with pictures of postoperative scars were sent to laypeople who assessed scar quality with Modified Scar-Rating Scale scores for surface appearance, height, and color of the scar tissue. Statistical analysis was carried out for significance. Results: Twenty-eight patients with a unilateral cleft underwent arm restraints after primary lip repair, and twenty-seven utilized mittens. In total, 42 medical students completed the scar assessment. Photographs were taken an average of 23.9 (±5.8) and 28.2 (±11.9) months postoperatively in the restraint and mitten groups, respectively (p = 0.239). There were no statistically significant differences in scores between scar surface, height, color, or overall scar appearance. Complication rates were also similar between groups. Conclusions: Arm restraints appear to have no additional benefit relative to scar quality, as compared to mittens. Considering the arm restraints' burden of care, mittens should be considered as a measure to protect the lip after primary repair.

Quantifying Sagittal Lip Changes in Patients with Bilateral Cleft Lip Post Abbe Flap Reconstruction.

OBJECTIVES: To objectively quantify results of sagittal lip changes following Abbe flap reconstruction in patients with bilateral cleft lip. DESIGN: Retrospective, observational study. SETTING: Single institution, 8-year retrospective review. PATIENTS/PARTICIPANTS: In total, 17 patients with bilateral cleft lip that underwent Abbe flap reconstruction were included in this study. INTERVENTION: Patients had lateral photographs taken prior to Abbe flap reconstruction and at least 8 months post-Abbe flap. MAIN OUTCOME MEASUREMENTS: Vegter's index, Sushner's S2 line and Burstone's B line reference lines were used for evaluation of sagittal lip changes. Wilcoxon signed rank tests were used in analysis. RESULTS: The mean pre-Abbe flap upper to lower lip ratio, defined as Vegter's Lip Index, was 0.906 compared to a mean of 0.946 following Abbe flap reconstruction. The mean upper to lower lip ratio for Sushner's S2 and Burstone's B line exhibited an increase in upper lip sagittal projection from -0.164 to 1.459 and 0.259 to 0.957, respectively (P < 0.001). CONCLUSIONS: This study quantifies sagittal changes to upper and lower lip position after Abbe flap reconstruction. These findings may aid in operative planning and patient/caregiver expectations during counseling.

Contemporary Prevalence of Oral Clefts in the US: Geographic and Socioeconomic Considerations.

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.

Same-day Discharge for Cleft Palate Repair: A Single-Surgeon Retrospective Analysis.

OBJECTIVE: To evaluate the safety of same-day discharge for patients undergoing primary cleft palate repair. DESIGN: Single-surgeon retrospective review. SETTING: Tertiary care institution. PATIENTS/PARTICIPANTS: 40 consecutive patients that underwent primary cleft palate repair by a single surgeon from September 2018 to June 2023. INTERVENTIONS: Same-day discharge versus overnight admission after primary palatoplasty. MAIN OUTCOME MEASURES: 30-day readmission, reoperation, wound and all-cause complication rate and 1-year fistula incidence. RESULTS: Of 40 total cases, 20 patients were discharged on the same calendar day and 20 patients were admitted for overnight stay following primary cleft palate repair. In the same-day discharge group, readmission incidence was 10%(n = 2), wound complication incidence was 5%(n = 1), and postoperative complication incidence was 15%(n = 3). In comparison, patients admitted overnight had a readmission incidence of 5%(n = 1, P = 1.00), wound complication incidence of 10%(n = 2, P = 1.00), and postoperative complications of 20%(n = 4, P = 1.00) No patients had 30-day reoperations or fistulas at 1 year. A higher proportion of admitted patients held a preoperative diagnosis of unilateral cleft palate and alveolus (Veau 3) as compared to patients discharged on the same day (P = .019). During the postoperative hospital course, admitted patients received significantly more oxycodone at median of 2 doses (IQR 1.00-3.75) and acetaminophen at a median of 4 doses (IQR 3.00-5.00) than patients with same-day discharge with a median of 1 dose (IQR 0.00 -1.00, P < .001). CONCLUSIONS: In a low-risk patient population, same-day discharge following primary cleft palate repair may be safely undertaken and result in similar short-term outcomes and 1-year fistula incidence as patients admitted for overnight stay.

Virtual Reality Simulation of Airway Management Post-Cleft Palate Surgery: A Model for Sustainable and Equitable Education.

BACKGROUND: The effectiveness of virtual-reality (VR) simulation-based training in cleft surgery has not been tested. The purpose of this study was to evaluate learners' acceptance of VR simulation in airway management of a pediatric patient post-cleft palate repair. METHODS: This VR simulation was developed through collaboration between BioDigital and Smile Train. 26 medical students from a single institution completed 10 min of standardized VR training and 5 min of standardized discussion about airway management post-cleft palate repair. They spent 4-8 min in the VR simulation with guidance from a cleft surgery expert. Participants completed pre- and post-surveys evaluating confidence in using VR as an educational tool, understanding of airway management, and opinions on VR in surgical education. Satisfaction was evaluated using a modified Student Evaluation of Educational Quality questionnaire and scored on a 5-point Likert scale. Wilcoxon signed-rank tests were performed to evaluate responses. RESULTS: There was a significant increase in respondents' confidence using VR as an educational tool and understanding of airway management post-cleft palate repair after the simulation (P < .001). Respondents' opinions on incorporating VR in surgical education started high and did not change significantly post-simulation. Participants were satisfied with VR-based simulation and reported it was stimulating (4.31 ± 0.88), increased interest (3.77 ± 1.21), enhanced learning (4.12 ± 1.05), was clear (4.15 ± 0.97), was effective in teaching (4.08 ± 0.81), and would recommend the simulation (4.2 ± 1.04). CONCLUSION: VR-based simulation can significantly increase learners' confidence and skills in airway management post-cleft palate repair. Learners find VR to be effective and recommend its incorporation in surgical education.

Association of Commonly Prescribed Antepartum Medications and Incidence of Orofacial Clefting.

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.

Direct inkjet writing type 1 bovine collagen/ß-tricalcium phosphate scaffolds for bone regeneration.

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 ß-tricalcium phosphate (COL/ß-TCP). A custom-built direct inkjet write (DIW) printer was used to fabricate ß-TCP, COL, and COL/ß-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 ß-TCP in the 3D printed COL/ß-TCP scaffolds, which exhibited crystals that were attributed to ß-TCP due to the presence of calcium and phosphorus, detected through energy dispersive x-ray spectroscopy. In vitro studies showed that the COL/ß-TCP scaffolds yielded more favorable results in terms of cell viability and proliferation compared to ß-TCP and COL scaffolds. The novel COL/ß-TCP scaffold constructs hold promise for improving BTE applications and may offer a superior environment for bone regeneration compared with conventional COL and ß-TCP scaffolds.

Abbe Flap Division Before Two Weeks' Time: Harmful or Advantageous?

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.

The Burden of Care of Nasoalveolar Molding: An Institutional Experience.

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.

Anatomical Study of Domain Rescue of Palatal Length in Patients With a Wide Cleft Palate: Buccal Flap Reconstruction in Primary Palatoplasty.

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.

Defining the Treatment Gap in Nasoalveolar Molding: Factors Affecting the Utilization of NAM in an Urban Cleft Center.

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.

Internet-based Digital Simulation for Cleft Surgery Education: A 10-year Assessment of Demographics, Usage, and Future Directions.

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.

LeFort I Horizontal Osteotomy: Defining the Feasibility of the "High Osteotomy".

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.

A novel treatment of pediatric bilateral condylar fractures with lateral dislocation of the temporomandibular joint (TMJ) using transfacial pinning.

A 3-year-old patient sustained a tripartite mandibular fracture, including bilateral condylar fractures with lateral dislocation of the left condyle and symphyseal fracture. Staged lower jaw reconstruction with closed reduction of the laterally dislocated condyle, transfacial pinning between the mandibular angles, MMF using circummandibular wiring and intermaxillary fixation screws was performed.

Three-Dimensional Printing Bioceramic Scaffolds Using Direct-Ink-Writing for Craniomaxillofacial Bone Regeneration.

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 ß-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.

"The Effects of Gingivoperiosteoplasty and Cleft Palate Repair on Facial Growth."

PURPOSE: 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 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: sella-nasion-point A (SNA), sella-nasion-point B (SNB), and A point-nasion-B point (ANB). Landmarks were compared between patient groups and to Eurocleft Center D data. RESULTS: 110 patients met inclusion criteria: 7 CLA-GPP, 16 CLA+GPP, 24 CLP-GPP, and 63 CLP+GPP patients. There were no significant differences in SNA, SNB, and ANB 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 to 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 to 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.

Characterizing Cleft Rhinoplasty Across Skeletal Maturity: A Systematic Review of Terminology and Surgical Techniques.

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.
