The First Hybrid International Educational Comprehensive Cleft Care Workshop.

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.

Double-pedicle unaffected split-breast flap for unilateral breast reconstruction.

BACKGROUND: In some breast cancer patients with a contralateral unaffected hypertrophic and ptotic breast, autologous small-breast reconstruction with contralateral breast reduction is a good option. The current study is aimed to assess the efficacy of the double-pedicle unaffected split-breast (USB) flap harvested from the central half of the unaffected breast for unilateral breast reconstruction with contralateral transverse scar reduction mammoplasty. METHODS: Between February 2003 and May 2020, 14 patients underwent breast reconstruction using the USB flap. The mean patient age was 59.1 (range: 48-76) years, and the mean body mass index was 24.2 (range: 19.5-33.3) kg/m2 . This flap comprised half of the contralateral breast tissues with the 3rd or 4th internal mammary perforator (IMAP) and the lateral thoracic vessel (LTA/V). After USB flap elevation and LTA/V resection, flap perfusion from the IMAP was evaluated on indocyanine green (ICG) angiography. The medial pedicle USB flap was rotated 180° and was transferred to the affected site via the midline. The LTA/V was anastomosed to the recipient vessel to supercharge the distal part of the USB flap, which was then used for breast reconstruction. Then, the remaining contralateral upper and lower breast poles were used for transverse scar reduction mammoplasty. RESULTS: The mean flap size was 13.3 × 26.9 (range: 9.5 × 22 to 16 × 29) cm. All flaps and reduced breasts survived without serious complications such as flap necrosis, although there was one patient with hematoma and one patient with hypertrophic scar. ICG revealed poor perfusion in the distal, lateral part of the flap, ranging from 22.0% to 48.5% of the overall flap area. Final aesthetic evaluation was high, with 11 cases (78.6%) being "good" or "excellent" and 3 cases (21.4%) that were either poor or fair. The mean follow-up period for the patients was 53.8 (range: 15-84) months, with none of the patients presenting second primary breast cancer or recurrence in both breasts. CONCLUSION: USB flap breast reconstruction with contralateral reduction mammoplasty is a valuable option in breast cancer patients with a hypertrophic and ptotic breast.

Differences in subtrochanteric and diaphyseal atypical femoral fractures in a super-aging prefectural area: YamaCAFe Study.

INTRODUCTION: Atypical femoral fractures (AFFs) have been correlated with long-term use of bisphosphonates (BPs), glucocorticoids (GCs), and femoral geometry. We investigated the incidence and characteristics of subtrochanteric (ST) and diaphyseal (DP) AFFs in all institutes in a super-aging prefectural area. MATERIALS AND METHODS: We performed a blinded analysis of radiographic data in 87 patients with 98 AFFs in all institutes in Yamagata prefectural area from 2009 to 2014. Among the 98 AFFs, 57 AFFs comprising 11 ST fractures in 9 patients and 46 DP fractures in 41 patients with adequate medical records and X-rays were surveyed for time to bone healing and geometry. RESULTS: Of the 87 patients, 67 received BPs/denosumab (77%) and 10 received GCs (11%). Surgery was performed in 94 AFFs. Among 4 AFFs with conservative therapy, 3 required additional surgery. In univariate regression analyses for ST group versus DP group, male-to-female ratio was 2/7 versus 1/40, mean age at fracture was 58.2 (37-75) versus 78 (60-89) years, rheumatic diseases affected 55.5% (5/9) versus 4.9% (2/41), femoral lateral bowing angle was 1.7 (0-6) versus 11.8 (0.8-24)°, GC usage was 67% (6/9) versus 4.9% (2/41), and bone healing time was 12.1 (6-20) versus 8.1 (3-38) months (p < 0.05). In multivariate analyses, higher male-to-female ratio, younger age, greater proportion affected by rheumatic diseases, and higher GC usage remained significant (p < 0.05). CONCLUSIONS: The incidence of AFFs in our prefectural area was 1.43 cases/100,000 persons/year. This study suggests that the onset of ST AFFs have greater correlation with the worse bone quality, vice versa, the onset of DP AFFs correlated with the bone geometry. The developmental mechanisms of AFFs may differ significantly between ST and DP fractures.

Evaluation of cardiac beat synchronization control for a rotary blood pump on valvular regurgitation with a mathematical model.

We have studied the cardiac beat synchronization (CBS) control for a rotary blood pump (RBP) and revealed that it can promote pulsatility and reduce cardiac load. Besides, patients with LVAD support sometimes suffer from aortic and mitral regurgitation (AR and MR). A control method for the RBP should be validated in wider range of conditions to clarify its benefits and pitfalls prior to clinical application. In this study, we evaluated pulsatility and cardiac load reduction obtained with the CBS control on valvular failure conditions with a mathematical model. Diastolic assist could reduce cardiac load on the left ventricle by decreasing external work of the ventricle even in MR cases while it was not so effective in AR cases. Systolic assist can still promote pulsatility in AR and MR cases; however, aortic valve function should be carefully confirmed since pulse pressure can be wider not due to systolic assist but to AR.

Extended Maxillotomy for Nasopharynx Access in Infantile Immature Teratoma.

Infantile immature teratoma located in the nasopharynx is a rare congenital tumor that is not easily removed. Three surgeries and chemotherapy for recurrence of the tumor have been performed since a male infant with a nasopharyngeal mass was born at a gestational age of 35 weeks. Extended maxillotomy combining Le Fort I osteotomy with midline palatal split was performed at 2 years and 6 months of age. Residual tumor left in the intracranial region had not increased as of 4 years of age. Careful follow-up is needed until the patient reaches adulthood.

Development of a Method for Scaffold-Free Elastic Cartilage Creation.

Microtia is a congenital aplasia of the auricular cartilage. Conventionally, autologous costal cartilage grafts are collected and shaped for transplantation. However, in this method, excessive invasion occurs due to limitations in the costal cartilage collection. Due to deformation over time after transplantation of the shaped graft, problems with long-term morphological maintenance exist. Additionally, the lack of elasticity with costal cartilage grafts is worth mentioning, as costal cartilage is a type of hyaline cartilage. Medical plastic materials have been transplanted as alternatives to costal cartilage, but transplant rejection and deformation over time are inevitable. It is imperative to create tissues for transplantation using cells of biological origin. Hence, cartilage tissues were developed using a biodegradable scaffold material. However, such materials suffer from transplant rejection and biodegradation, causing the transplanted cartilage tissue to deform due to a lack of elasticity. To address this problem, we established a method for creating elastic cartilage tissue for transplantation with autologous cells without using scaffold materials. Chondrocyte progenitor cells were collected from perichondrial tissue of the ear cartilage. By using a multilayer culture and a three-dimensional rotating suspension culture vessel system, we succeeded in creating scaffold-free elastic cartilage from cartilage progenitor cells.

Evaluation of Congenital Maxillary Growth Using Computed Tomography in Patients With Bilateral Cleft Lip and Palate.

OBJECTIVE: To analyze congenital lateral maxillary growth for patients with bilateral cleft lip and palate (BCLP). DESIGN: A retrospective study. SETTING: Kanagawa Children's Medical Center. MATERIALS: Images from computed tomography (CT) of patients with BCLP and control patients that were previously used for treatment. MAIN OUTCOME MEASURES: The following landmarks were used: A, the posterior most point of the piriform aperture; B, the superior most point of the acoustic meatus; C, the point at which line A-B intersects the line drawn perpendicular from line A-B to the maxillary tuberosity; and D, the apical most point of the nasal bone. The following distances were then measured using these landmarks: (1) A-B distance; (2) A-C distance; (3) A-C/A-B; (4) the angle between lines A-B and A-D (∠BAD); and (5) B-D distance. RESULT: Mean A-B and A-C distances and A-C/A-B were significantly smaller in the BCLP group than in the control group (P < .01 each). Mean ∠BAD was significantly larger in the BCLP group than in the control group (P < .01). Mean B-D distance did not differ significantly between groups. CONCLUSIONS: Our results indicated that the lateral maxillary segments of patients with BCLP were more posterior than those of the control group, and segment length was shorter compared to the control group on 3D-CT analysis. The lateral maxillary segments of patients with BCLP were basically suggested to originally be underdeveloped.

Developing and Sustaining an Open Source Electronic Health Record: Evidence from a Field Study in Japan.

Electronic Health Records (EHRs) are at the heart of reforms aimed at improving the efficiency and quality of healthcare services provided to citizens. Although there is still some skepticism, open source (OS) EHR is a growing phenomenon in health informatics. Given the widespread adoption of OS software (OSS) in several domains, including operating systems, and enterprise systems, the repeated shortfalls faced by healthcare organizations with dominant proprietary EHRs create an opportunity for other alternatives, such as OSS to demonstrate their abilities in addressing these well-documented problems, including inflexibility, high costs, and low interoperability. However, scholars have expressed extensive concerns about the sustainability of OS EHR. Recognizing that OSS project sustainability relies on their governance arrangements, this case study reports on the evolution of the governance and sustainability of a Japanese OS EHR project and provides rich insights to other open source EHR initiative stakeholders, including physicians, developers, researchers, and policy-makers.

The Development of Medical Markup Language Version 4 as a Clinical Document Exchange Format for Nationwide EHR Systems.

Medical Markup Language (MML) is a standard format for exchange of healthcare data among healthcare providers. Following the last major update (version 3), we developed new modules and discussed the requirements for the next major updates. Subsequently, in 2016 we released MML version 4 and used it to obtain clinical data from healthcare providers for a nationwide electronic health records (EHR) system. In this article we provide an overview of this major update of MML version 4 and discuss its interoperability for clinical data.

The prevalence and disease burden of severe eosinophilic asthma in Japan.

Background: There are limited data on the prevalence and burden of severe eosinophilic asthma (SEA) both in Japan and globally. This study aimed to assess the prevalence and burden of SEA in Japan. Methods: This study was a retrospective, observational cohort analysis using health records or health insurance claims from patients with severe asthma treated at Kyoto University Hospital. The primary outcome was the prevalence of SEA, defined as a baseline blood eosinophil count ≥300 cells/µL. Secondary outcomes included frequency and risk factors of asthma exacerbations, and asthma-related healthcare resource utilization and costs. Results: Overall, 217 patients with severe asthma were included; 160 (74%) had eosinophil assessments. Of these, 97cases (61%), 54cases (34%), and 33cases (21%) had a blood eosinophil count ≥150, ≥300, and ≥500 cells/µL, respectively. Proportion of SEA was 34%. Blood eosinophil count was not associated with a significantly increased frequency of exacerbations. In the eosinophilic group, lower % forced expiratory volume in 1 second and higher fractional exhaled nitric oxide were predictive risk factors, while the existence of exacerbation history was a predictive risk factor for asthma exacerbations in the non-eosinophilic group. Severe asthma management cost was estimated as ¥357,958/patient-year, and asthma exacerbations as ¥26,124/patient-year. Conclusions: Approximately, one-third of patients with severe asthma in Japan have SEA. While risk factors for exacerbations differed between SEA and severe non-eosinophilic asthma, both subgroups were associated with substantial disease and economic burden. From subgroup analysis, blood eosinophil counts could be an important consideration in severe asthma management.

Mathematical evaluation of cardiac beat synchronization control used for a rotary blood pump.

We studied a control method of rotary blood pumps (RBPs), which is called as the cardiac beat synchronization (CBS) system. Usually, RBPs operate at constant target rotational speed, meanwhile, the CBS system modulates target speed synchronizing with cardiac beat. We built a computer simulation method to evaluate the CBS system. This simulator acquires a mathematical model of a circulatory system including a RBP and can provide us the theoretical hemodynamics when our control method is applied. We compared theoretical results with experimental ones with the model focusing on both pulsatility and aortic valve (AV) opening interval enhanced by the CBS system. Our simulator could reproduce behavior of the circulatory system whether the RBP is connected or not. Comparison among no RBP, constant assist, systolic assist, and diastolic assist modes indicated that pulsatility is enhanced with systolic assist theoretically. While systolic assist decreased AV opening interval, diastolic assist made it longer than the ones in other control strategies.

Perinasal Osteotomy With Distraction Osteogenesis for a Mild Syndromic Craniosynostosis.

Le Fort II and III procedures have generally been performed for syndromic craniosynostosis with midfacial hypoplasia and skeletal class III malocclusion. However, some patients have midfacial hypoplasia without malocclusion. Perinasal osteotomy was performed with distraction osteogenesis to move the midface forward in 2 patients (a 17-year old female patient with Crouzon-like disease and a 15-year-old female patient with Antely-Bixler syndrome) with mild midface hypoplasia without malocclusion. The success of the procedure was assured by 3 features: the intermaxillary sutures were fixed by a mini metal plate to prevent separation during distraction; the distraction wires were fixed through the bone of the piriform aperture with the mini metal plates to prevent the wires from coming off; and the osteotomy line was designed in front of the palatomaxillary suture to avoid suture damage. These were expected to secure the procedure. Perinasal osteotomy with distraction osteogenesis is considered one of the recommended procedures for mild midfacial hypoplasia as seen in mild syndromic craniosynostosis without malocclusion.

Overcorrected Midface Advancement to Improve Airway Problems in Severe Pfeiffer Syndrome Types II and III.

INTRODUCTION: Treatment of patients with severe Pfeiffer syndrome types II and III is difficult. The purpose of this article is to present our method of overcorrecting midface advancement to improve airway problems in such patients. MATERIALS AND METHODS: One boy and two girls with types II and III Pfeiffer syndrome and who underwent Le Fort III midface advancement using our previously described corrected cephalometric analysis and distraction system were included in the study. RESULTS: The authors overcorrected by advancing the midface to make it look as similar as possible to an adult face. While the overcorrected midface advancement widened the upper airway spaces in the 3 patients, the tracheostomy that had already been placed during infancy could not be closed, probably because of an underlying tracheal abnormality or tracheomalacia. DISCUSSION: Overcorrected midface advancement cannot enable tracheostomy closure, probably because of severe tracheal anomalies, such as tracheomalacia, below the tracheostomy. However, with the possibility of gradual improvement of the tracheomalacia with age, closure of the tracheostomy can eventually be expected. Therefore, efforts to close a tracheostomy should be pursued even if the probability of its removal is low. CONCLUSION: Overcorrected midface advancement did not enable tracheostomy closure, probably because of severe tracheal anomalies such as tracheomalacia. However, the severe exophthalmos and angle III malocclusion were improved, and with the possibility of gradual improvement of the tracheomalacia with age, closure of the tracheostomy can eventually be expected. Therefore, efforts to close a tracheostomy should be pursued even if the probability of its removal is low.

Application for lower facial fat reduction and tightening by static type monopolar 1-MHz radio frequency for body contouring.

INTRODUCTION: Liposuction and mesotherapy are popular treatments for fat reduction of lower face, but because these treatments are invasive, a novel non-invasive treatment with similar or better efficacy has been sought. There are various devices such as CoolSculpt, laser, RF, and HIFU that are used as non-invasive treatments for fat reduction and body contouring, but these applications have not been applied to facial fat reduction. In this study, we selected Monopolar 1-MHz RF for body contouring to be applied for fat reduction and tightening of the lower face. MATERIAL AND METHODS: From March through August of 2016, we treated fourteen Asian women (average age: 44.6 years old) for fat reduction and tightening of the lower face using 1-MHz Monopolar RF (truSculpt™, Cutera, Inc., Brisbane, CA). We performed the treatment primarily in the nasolabial fold and buccal area weekly for five consecutive weeks, and evaluated the effects for fat reduction and tightening before each treatment and for 2 months after the treatment using handy VECTRA 3D® (Canfield Scientific, Inc.) for imaging. Three-dimensional (3D) volumetric assessments were performed at pre- and post-two-months after treatment. Patients rated their satisfaction for tightening using a 5-points scale. RESULTS: During the study, more than ninety percent of patients showed volumetric change by fat reduction at the treated area, with an average of 2.7 ml. Sixty percent of patients were either "satisfied" or "very satisfied" with the tightening effects. The treatments were accompanied only by very mild heat pain. Efficacy was maintained for 2 months after the treatments, and three patients showed a higher fat reduction effect at 2 months after the final treatment compared with the final treatment. A mild redness was observed just for few hours after the treatment, but complications such as, swelling, induration, burn, sensory disturbance or facial paralysis, were not observed. CONCLUSION: In this study, we found that Monopolar 1-MHz RF applied with a stationary applicator was effective especially for lower face fat reduction and with a tightening effect in facial contouring. A highly efficacious treatment with satisfactory comfort and safety can be achieved with no downtime, and the device has the potential for becoming one of the standard non-invasive treatments for fat reduction of facial contouring.

The Incidence of Atypical Femoral Fractures in Patients with Rheumatic Disease: Yamagata Prefectural Committee of Atypical Femoral Fractures (YamaCAFe) Study.

Atypical femoral fractures (AFFs) have been reported to occur with minimal or spontaneous subtrochanteric and femoral shaft fractures with a characteristic transverse pattern, compared with typical femoral fractures in young patients with high-energy trauma. AFFs are related to long-term use of bisphosphonates (BPs), glucocorticoids and rheumatic diseases. We have estimated a blind analysis of AFFs in rheumatic patients receiving BPs and glucocorticoids ordinary over a long time in all Yamagata prefectural area through radiographic examination. The 123 AFFs including suspected cases over six years were collected and reviewed by two independent orthopedic surgeons. We found 86 patients with a total of 99 AFFs between 2009 and 2014 (1.43 cases/100,000 person/year). Of these 99 AFFs, 11 were in 8 rheumatic patients including three patients with bilateral AFFs. The incidence of AFFs in rheumatic patients had trend to increase from 2012. The mean age of all 8 patients was 54.9 years. All 8 patients received BPs and 7/8 received prednisolone (PSL). The mean dose of PSL was 14 mg/day. Compared to patients with unilateral AFFs, those with bilateral AFFs in rheumatic patients were on a higher dose of PSL (20 mg/day vs. 7 mg/day) and had less femoral neck-shaft angle (129° vs. 136°, p < 0.05). In conclusion, the incidence of AFFs in rheumatic patients showed a trend to increase from 2012 to 2014 in Yamagata prefecture. Careful management of AFFs is of particular importance in rheumatic patients who have taken high doses of PSL and have small femoral neck-shaft angle.

Immediate breast reconstruction using the free lumbar artery perforator flap and lateral thoracic vein interposition graft for recipient lateral thoracic artery anastomosis.

The lumbar artery perforator (LAP) flap, which contains excess skin and fat tissue, love handles, that extends from the lower back to upper buttock, may provide an alternate tissue source for autologous breast reconstruction. However, LAP flap use during this procedure frequently requires vessel interposition grafts to correct the short flap pedicle length and mismatched recipient vessel calibre. A 46-year-old patient underwent a right nipple-sparing mastectomy using a lateral approach for ductal carcinoma in situ and immediate LAP flap breast reconstruction. The lateral thoracic vessel served as the recipient vessel, and a lateral thoracic vein interposition graft from the distal remnant was performed to adjust the arterial length and size discrepancy between the recipient lateral thoracic artery and pedicle artery. This procedure facilitates microsurgical anastomosis and medialisation of LAP flap to make a natural decollete line and create a cleavage for the reconstructed breast.

Brief report: reconstruction of joint hyaline cartilage by autologous progenitor cells derived from ear elastic cartilage.

In healthy joints, hyaline cartilage covering the joint surfaces of bones provides cushioning due to its unique mechanical properties. However, because of its limited regenerative capacity, age- and sports-related injuries to this tissue may lead to degenerative arthropathies, prompting researchers to investigate a variety of cell sources. We recently succeeded in isolating human cartilage progenitor cells from ear elastic cartilage. Human cartilage progenitor cells have high chondrogenic and proliferative potential to form elastic cartilage with long-term tissue maintenance. However, it is unknown whether ear-derived cartilage progenitor cells can be used to reconstruct hyaline cartilage, which has different mechanical and histological properties from elastic cartilage. In our efforts to develop foundational technologies for joint hyaline cartilage repair and reconstruction, we conducted this study to obtain an answer to this question. We created an experimental canine model of knee joint cartilage damage, transplanted ear-derived autologous cartilage progenitor cells. The reconstructed cartilage was rich in proteoglycans and showed unique histological characteristics similar to joint hyaline cartilage. In addition, mechanical properties of the reconstructed tissues were higher than those of ear cartilage and equal to those of joint hyaline cartilage. This study suggested that joint hyaline cartilage was reconstructed from ear-derived cartilage progenitor cells. It also demonstrated that ear-derived cartilage progenitor cells, which can be harvested by a minimally invasive method, would be useful for reconstructing joint hyaline cartilage in patients with degenerative arthropathies.

A histone lysine methyltransferase activated by non-canonical Wnt signalling suppresses PPAR-gamma transactivation.

Histone modifications induced by activated signalling cascades are crucial to cell-lineage decisions. Osteoblast and adipocyte differentiation from common mesenchymal stem cells is under transcriptional control by numerous factors. Although PPAR-gamma (peroxisome proliferator activated receptor-gamma) has been established as a prime inducer of adipogenesis, cellular signalling factors that determine cell lineage in bone marrow remain generally unknown. Here, we show that the non-canonical Wnt pathway through CaMKII-TAK1-TAB2-NLK transcriptionally represses PPAR-gamma transactivation and induces Runx2 expression, promoting osteoblastogenesis in preference to adipogenesis in bone marrow mesenchymal progenitors. Wnt-5a activates NLK (Nemo-like kinase), which in turn phosphorylates a histone methyltransferase, SETDB1 (SET domain bifurcated 1), leading to the formation of a co-repressor complex that inactivates PPAR-gamma function through histone H3-K9 methylation. These findings suggest that the non-canonical Wnt signalling pathway suppresses PPAR-gamma function through chromatin inactivation triggered by recruitment of a repressing histone methyltransferase, thus leading to an osteoblastic cell lineage from mesenchymal stem cells.

Reconstruction of human elastic cartilage by a CD44+ CD90+ stem cell in the ear perichondrium.

Despite the great demands for treating craniofacial injuries or abnormalities, effective treatments are currently lacking. One promising approach involves human elastic cartilage reconstruction using autologous stem/progenitor populations. Nevertheless, definitive evidence of the presence of stem cells in human auricular cartilage remains to be established. Here, we demonstrate that human auricular perichondrium, which can be obtained via a minimally invasive approach, harbors a unique cell population, termed as cartilage stem/progenitor cells (CSPCs). The clonogenic progeny of a single CD44(+) CD90(+) CSPC displays a number of features characteristic of stem cells. Highly chondrogenic CSPCs were shown to reconstruct large (>2 cm) elastic cartilage after extended expansion and differentiation. CSPC-derived cartilage was encapsulated by a perichondrium layer, which contains a CD44(+) CD90(+) self-renewing stem/progenitor population and was maintained without calcification or tumor formation even after 10 mo. This is a unique report demonstrating the presence of stem cells in auricular cartilage. Utilization of CSPCs will provide a promising reconstructive material for treating craniofacial defects with successful long-term tissue restoration.

Primary vomerine osteotomy with gingivoperiosteoplasty for bilateral cleft lip and palate patients with protrusion and/or torsion of the premaxilla.

In patients with bilateral cleft lip and palate (BCLP) with protrusion and/or torsion of the premaxilla, achieving a favorable outcome with adequate facial and maxillary development remains challenging. In the present study, we report a retrospective cohort of patients with complete BCLP who were treated between 2017 and 2020 at a single center in Japan. We investigated the effects and complications of primary vomerine osteotomy (PVO) with gingivoperiosteoplasty (GPP) following pre-surgical orthodontics (PSO) for premaxillary protrusion and/or torsion. For patients with residual premaxillary protrusion and/or torsion after PSO, PVO, and GPP were performed. The distances and angles of the premaxilla were measured on dental casts before PSO, on the day of PVO, after PVO, and on the day of palatoplasty after cheiloplasty. We further assessed postoperative complications. From a total of 36 patients with complete BCLP after PSO, seven patients underwent PVO with GPP. Proper positioning of the premaxilla was achieved in all seven patients. The distance between the anterior edge of the premaxilla and the anterior edge of the lateral segment and the length of the premaxillary-lateral segment on both sides continued to decrease over time. Loosening of GPP sutures occurred in two cases, although no major complications such as necrosis of the premaxilla or fistula formation occurred. Vomerine osteotomy with GPP before primary cheiloplasty is a potential treatment option in BCLP when the premaxilla still protrudes despite PSO or because PSO cannot be applied.
