RESUMO

Midface hypoplasia (MFH) is a long-term sequela of cleft lip and palate repair, and is poorly understood. No study has examined the aggregate data on sagittal growth restriction of the midface following repair of the lip, but not palate, in these patients.A systematic review of 3780 articles was performed. Twenty-four studies met inclusion criteria and 11 reported cephalometric measurements amenable to meta-analysis. Patients with Veau class I-III palatal clefts were included so long as they had undergone only lip repair. Groups were compared against both noncleft and unrepaired controls.Cephalometrics were reported for 326 patients (31.3% female). Noncleft controls had an average SNA angle of 81.25° ± 3.12°. The only patients demonstrating hypoplastic SNA angles were those with unilateral CLP with isolated lip repair (77.4° ± 4.22°). Patients with repaired CL had SNA angles similar to noncleft controls (81.4° ± 4.02°). Patients with unrepaired CLP and CL tended toward more protruding maxillae, with SNA angles of 83.3° ± 4.04° and 87.9° ± 3.11°, respectively. Notably, when comparing SNA angles between groups, patients with CLP with isolated lip repair had significantly more hypoplastic angles compared to those with repaired CL (P < .0001). Patients with CLP with isolated lip repair were also more hypoplastic than noncleft controls (P < .0001). In contrast, there was no significant difference between the SNA of patients with repaired CL and controls (P = .648).We found that cleft lip repair only appeared to contribute to MFH in the setting of concurrent cleft palate pathology, suggesting that scarring from lip repair itself is unlikely to be the predominant driver of MFH development. However, studies generally suffered from inadequate reporting of timing, technique, follow-up time, and cleft severity.

RESUMO

Cleft palate is among the most common congenital disorders worldwide and is correctable through surgical intervention. Sub-optimal surgical results may cause velopharyngeal insufficiency (VPI). When symptomatic, VPI can cause hypernasal or unintelligible speech. The postoperative risk of VPI varies significantly in the literature but may be attributed to differences in study size, cleft type, surgical technique, and operative age. To identify the potential impact of these factors, a systematic review was conducted to examine the risk of VPI after primary palatoplasty, accounting for operative age and surgical technique. A search of PubMed, Embase, and Web of Science was completed for original studies that examined speech outcomes after primary palatoplasty. The search identified 4740 original articles and included 35 studies that reported mean age at palatoplasty and VPI-related outcomes. The studies included 10,795 patients with a weighted mean operative age of 15.7 months (range: 3.1-182.9 mo), and 20% (n=2186) had signs of postoperative VPI. Because of the heterogeneity in reporting of surgical technique across studies, small sample sizes, and a lack of statistical power, an analysis of the VPI risk per procedure type and timing was not possible. A lack of data and variable consensus limits our understanding of optimal timing and techniques to reduce VPI occurrence. This paper presents a call-to-action to generate: (1) high-quality research from thoughtfully designed studies; (2) greater global representation; and (3) global consensus informed by high-quality data, to make recommendations on optimal technique and timing for primary palatoplasty to reduce VPI.

RESUMO

ABSTRACT: Competing hypotheses for the development of midface hypoplasia in patients with cleft lip and palate include both theories of an intrinsic restricted growth potential of the midface and extrinsic surgical disruption of maxillary growth centers and scar growth restriction secondary to palatoplasty. The following meta-analysis aims to better understand the intrinsic growth potential of the midface in a patient with cleft lip and palate unaffected by surgical correction. A systematic review of studies reporting cephalometric measurements in patients with unoperated and operated unilateral cleft lip and palate (UCLP), bilateral cleft lip and palate (BCLP), and isolated cleft palate (iCP) abstracted SNA and ANB angles, age at cephalometric analysis, syndromic diagnosis, and patient demographics. Age and Region-matched controls without cleft palate were used for comparison. SNA angle for unoperated UCLP (84.5 ±â€Š4.0°), BCLP (85.3 ±â€Š2.8°), and ICP (79.2 ±â€Š4.2°) were statistically different than controls (82.4 ±â€Š3.5°), (all P ≤ 0.001). SNA angles for operated UCLP (76.2 ±â€Š4.2°), BCLP (79.8 ±â€Š3.6°), and ICP (79.0 ±â€Š4.3°) groups were statistically smaller than controls (all P ≤ 0.001). SNA angle in unoperated ICP (n = 143) was equivalent to operated ICP patients (79.2 ±â€Š4.2° versus 79.0 ±â€Š4.3° P = 0.78). No unoperated group mean SNA met criteria for midface hypoplasia (SNA < 80). Unoperated UCLP/BLCP exhibit a more robust growth potential of the maxilla, whereas operated patients demonstrate stunted growth compared to normal phenotype. Unoperated ICP demonstrates restricted growth in both operated and unoperated patients. As such, patients with UCLP/BCLP differ from patients with ICP and the factors affecting midface growth may differ.Level of Evidence: IV.

RESUMO

OBJECTIVE: To identify specific areas for improvement in cleft lip repair teaching. DESIGN: Secondary analysis of prospectively-collected, blinded data. SETTING: Three residency programs rotating at a single academic children's hospital. PARTICIPANTS: Plastic surgery residents, and craniofacial/pediatric plastic surgery fellows. MAIN OUTCOME MEASURES: Mean scores for each skill in an 18-item Unilateral Cleft Lip Repair competency assessment tool (UCLR) (1-3 scale for each item) were rank ordered. Correlation between level of training (PGY) and performance on steps of the procedure was examined using Pearson R. RESULTS: Simulation participants (n = 26) scored highest on skills in the "Marking" subscale (2.38-2.63 mean score). Procedural steps that scored lowest were: closing the nasal floor (2.00), repairing oral mucosa (2.15) and avoiding over/under-dissection (2.19). Interestingly, none of these skills correlated with PGY, suggesting they do not improve with training. CONCLUSIONS: These results suggest that marking cleft lip repair is taught well in our current teaching environment, while steps like closing the nasal floor and repairing the oral mucosa are taught less well. Improved teaching of these steps could be achieved with deliberate instruction, video, digital simulation, and high fidelity simulation.

RESUMO

INTRODUCTION: Increasing numbers of women in medicine could address Morocco's 5.5-fold deficit in surgical providers. Cultural perceptions towards women limit female advancement in healthcare. This study evaluates the impact of an all-female surgical team on Moroccan attitudes. OBJECTIVE: This study aimed to evaluate how attitudes towards female healthcare professionals changed for Moroccan patients after exposure to a unique, all-female medical environment. METHODS: Cleft patients were surveyed after a surgery mission with all-female volunteers in Oujda, Morocco. Analysis included quantitative, qualitative, and mixed-methods approaches. RESULTS: Of 121 respondents (94%), 85% and 77% had prior exposure to a female nurse or doctor, respectively. 94% of respondents strongly agreed to receiving high-quality care. 75% developed increased confidence in female providers. 68% and 69% of respondents, regardless of gender (p = 0.950), felt that having a female nurse or doctor did not impact care. Female patients were more likely than male patients to strongly encourage female relatives to pursue medical careers (p = 0.027). Respondents without prior exposure to female nurses were more likely to: pursue medical careers (p = 0.034), believe female relatives could pursue medical careers (p = 0.006), and encourage them to do so (p = 0.011). CONCLUSIONS: Increased visibility of women improved patient attitudes towards female providers, especially in patients without prior exposure. Initiatives that increase female representation in healthcare may have greater effects in cultures with more gender inequity.

RESUMO

ABSTRACT: Crowd sourcing has been used in multiple disciplines to quickly generate large amounts of diverse data. The objective of this study was to use crowdsourcing to grade preoperative severity of unilateral cleft lip phenotype in a multiethnic cohort with the hypothesis that crowdsourcing could efficiently achieve similar rankings compared to expert surgeons. Deidentified preoperative photos were collected for patients with primary, unilateral cleft lip with or without cleft palate (CL ±â€ŠP). A platform was developed with C-SATS for pairwise comparisons utilizing Elo rankings by crowdsource workers through Amazon Mechanical Turk. Images were independently ranked by 2 senior surgeons for comparison. Seventy-six patients with varying severity of unilateral (CL ±â€ŠP) phenotype were chosen from Operation Smile missions in Bolivia, Madagascar, Vietnam, and Morocco. Patients were an average of 1.2 years' old, ranging from 3 months to 3.3 years. Each image was compared with 10 others, for a total of 380 unique pairwise comparisons. A total of 4627 total raters participated with a median of 12 raters per pair. Data collection was completed in <20 hours. The crowdsourcing ranking and expert surgeon rankings were highly correlated with Pearson correlation coefficient of R = 0.77 (P = 0.0001). Crowdsourcing provides a rapid and convenient method of obtaining preoperative severity ratings, comparable to expert surgeon assessment, across multiple ethnicities. The method serves as a potential solution to the current lack of rating systems for preoperative severity and overcomes the difficulty of acquiring large-scale assessment from expert surgeons.

RESUMO

ABSTRACT: Developing midface hypoplasia is common after palatoplasty and has been hypothesized to be influenced by the timing of hard palate repair. This meta-analysis assesses the risk of developing midface hypoplasia based on age at hard palate repair. A Pubmed PRISMA systematic review and meta-analysis was completed for literature focused on palatoplasty and midface hypoplasia published between 1970 and 2019. Cephalometric data were extracted and categorized by age at hard palate repair: <6, 7 to 12, 13 to 18, 19 to 24, and 25 to 83 months. Analysis of these groups and a control were compared using independent T-tests and Spearman correlation coefficients. SNA angles for each group were 77.9 ±â€Š3.1° (<6 months), 77.7 ±â€Š4.2° (7-12 months), 78.7 ±â€Š4.2° (13-18 months), 75.1 ±â€Š4.2° (19-24 months), 75.5 ±â€Š4.8° (25-83 months), and were statistically different than the control group 82.4 ±â€Š3.5° (P < 0.0001). Hard palate repair at 13 to 18 months had a statistically significant greater SNA angle than all other groups except for the repair at <6 months group (P = 0.074). As age at hard palate closure increased beyond 18 months, the SNA decreased, corresponding to a more hypoplastic maxilla (Spearman's correlation coefficient -0.381, P = 0.015). Analysis suggests that younger age at the time of repair is less likely to create in midface hypoplasia in adulthood. Minimizing midface hypoplasia in cleft palate patients by optimizing algorithms of care is a practical way to decrease the burden of disease on patients, families and medical systems. Further studies are needed to evaluate the role of technique on outcomes.Level of Evidence: IV.

RESUMO

ABSTRACT: Midface hypoplasia is one of the most significant sequelae of cleft lip and/or palate surgery. A complete understanding of the rate of orthognathic surgery across varying cleft phenotypes is a powerful tool for educating patients and families as to the treatment course that the patient will incur during their lifetime. Understanding the average rates of orthognathic intervention also can act to develop metrics for outcome evaluation with different treatment protocols. Attempting to identify the average rates of orthognathic intervention, the authors conducted a systematic review and meta-analysis by combining studies from 1987 to 2016 describing the frequency of orthognathic intervention on the different cleft phenotypes as the primary outcome. Secondary outcomes included identification of surgical protocol, age of patient at orthognathic intervention, and the method by which patients were evaluated for orthognathic intervention. The rate of orthognathic surgery was 38.1% for bilateral cleft lip and palate (BCLP), 30.2% for unilateral cleft lip and palate (UCLP), 4.4% for isolated cleft palate (ICP), and 1.8% for patients with isolated cleft lip (ICL). 71% (n = 10) reported using lateral cephalograms for orthognathic surgery evaluation and only one of those studies reported specific objective cephalometric measurements for orthognathic intervention. Our findings demonstrated that BCLP possessed the highest rate of orthognathic intervention followed by UCLP, ICP, and ICL. ICP and ICL both possessed low rates of orthognathic intervention. By sharing our findings, the authors hope to provide a useful tool for informing patients' families as to their risk of needing orthognathic intervention.

RESUMO

ABSTRACT: The understanding of cleft lip etiology and approaches for surgical repair have evolved over time, allowing for improved ability to restore form and function. The variability of cleft lip presentations has necessitated a nuanced surgical approach with multidisciplinary cleft care. The earliest documentation of unilateral cleft lip repair predates the 19th century, with crude outcomes observed before the advent of curved incisions and advancement flaps. In the 20th century, straight line, quadrilateral flap, and triangular flap repairs were introduced to mitigate post-repair surgical scarring, increase lip length, and restore the symmetry of the Cupid's bow. Towards the latter part of the century, the development of rotation-advancement principles allowed for improved functional and aesthetic outcomes. Future technical improvements will continue to address the goals of lip and nasal symmetry, muscular continuity, precise scar concealment, and improved patient satisfaction in an increasing range of cleft phenotypes and during subsequent years of growth.

RESUMO

INTRODUCTION: The Lancet Commission for Global Surgery identified an adequate surgical workforce as one indicator of surgical care accessibility. Many countries where women in surgery are underrepresented struggle to meet the recommended 20 surgeons per 100,000 population. We evaluated female surgeons' experiences globally to identify strategies to increase surgical capacity through women. METHODS: Three database searches identified original studies examining female surgeon experiences. Countries were grouped using the World Bank income level and Global Gender Gap Index (GGGI). RESULTS: Of 12,914 studies meeting search criteria, 139 studies were included and examined populations from 26 countries. Of the accepted studies, 132 (95%) included populations from high-income countries (HICs) and 125 (90%) exclusively examined populations from the upper 50% of GGGI ranked countries. Country income and GGGI ranking did not independently predict gender equity in surgery. Female surgeons in low GGGI HIC (Japan) were limited by familial support, while those in low income, but high GGGI countries (Rwanda) were constrained by cultural attitudes about female education. Across all populations, lack of mentorship was seen as a career barrier. HIC studies demonstrate that establishing a critical mass of women in surgery encourages female students to enter surgery. In HICs, trainee abilities are reported as equal between genders. Yet, HIC women experience discrimination from male co-workers, strain from pregnancy and childcare commitments, and may suffer more negative health consequences. Female surgeon abilities were seen as inferior in lower income countries, but more child rearing support led to fewer women delaying childbearing during training compared to North Americans and Europeans. CONCLUSION: The relationship between country income and GGGI is complex and neither independently predict gender equity. Cultural norms between geographic regions influence the variability of female surgeons' experiences. More research is needed in lower income and low GGGI ranked countries to understand female surgeons' experiences and promote gender equity in increasing the number of surgical providers.

RESUMO

BACKGROUND: Most people who lack adequate access to surgical care reside in low- and lower-middle-income countries. Few studies have analyzed the barriers that determine the ability to access surgical treatment. We seek to determine which barriers prevent access to cleft care in a resource-limited country to potentially enable barrier mitigation and improve surgical program design. METHODS: A cross-sectional, multi-site study of families accessing care for cleft lip and palate deformities was performed in Vietnam. A survey instrument containing validated demographic, healthcare service accessibility, and medical/surgical components was administered. The main patient outcome of interest was receipt of initial surgical treatment prior to 18 months of age. RESULTS: Among 453 subjects enrolled in the study, 216 (48%) accessed surgical care prior to 18 months of age. In adjusted regression models, education status of the patient's father (OR 1.64; 95% CI 1.1-2.5) and male sex (OR 1.61; 95% CI 1.1-2.4) were both associated with timely access to care. Distance and associated cost of travel, to either the nearest district hospital or to the cleft surgical mission site, were not associated with timing of access. In a sensitivity analysis considering care received prior to 24 months of age, cost to attend the surgical mission was additionally associated with timely access to care. CONCLUSIONS: Half of the Vietnamese children in our cohort were not able to access timely surgical cleft care. Barriers to accessing care appear to be socioeconomic as much as geographical or financial. This has implications for policies aimed at reaching vulnerable patients earlier.

RESUMO

PURPOSE: Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft. METHODS: A retrospective review from 1996 to 2010 was performed on a single senior surgeon's private university-based practice. Patient demographic information and fracture characteristics were obtained to evaluate for influence on success and time to union. RESULTS: There were 32 patients identified for inclusion in this study. Union was achieved in 100% of the patients, including 44% that had proximal pole fractures. The median time from injury to surgery was 41.86 weeks. The median time from surgery to healing was 17.93 weeks. Time to union was not affected by patient age, fracture location, smoking, alcohol use, or time to treatment. CONCLUSION: K-wire fixation and ICBG for treatment of scaphoid nonunion using our technique have equal or superior union rates compared to other techniques in the literature. This paper highlights the keys to success using this method. LEVEL OF EVIDENCE: Therapeutic Level IV.

RESUMO

OBJECTIVE: To present a model for integrated global health fellowships in plastic surgical residency training. BACKGROUND: National surveys have found that North American surgical residents have significant interest in international training. While global health training opportunities exist, less than a third of these are housed within surgical residency programs; even fewer are designed specifically for plastic surgery residents. METHODS: The Tsao Fellowship was created through a partnership between Operation Smile, Children's Hospital Los Angeles, Shriners Hospital for Children, and the University of Southern California. Designed for Accreditation Council for Graduate Medical Education accredited plastic surgery residents between their third and fourth years of residency, the fellowship curriculum is completed over 24 months and divided into 3 areas: clinical research, international reconstructive surgery fieldwork, and the completion of a Master of Science in Clinical and Biomedical Investigations. RESULTS: The Tsao Fellowship has matriculated 4 fellows: 3 have graduated from the program and 1 is in the current cycle. Fellows completed 4 to 7 international missions each cycle and have performed an aggregate total of 684 surgical procedures. Each fellow also conducted 2 to 6 research projects and authored several publications. All fellows continue to assume leadership roles within the field of global reconstructive surgery. CONCLUSIONS: Comprehensive global health fellowships provide invaluable opportunities beyond surgical residency. The Tsao Fellowship is a model for integrating international surgical training with global health research in plastic surgical residency that can be applied to other residency programs and different surgical specialties.

RESUMO

BACKGROUND: Several lifestyle and environmental exposures have been suspected as risk factors for oral clefts, although few have been convincingly demonstrated. Studies across global diverse populations could offer additional insight given varying types and levels of exposures. METHODS: We performed an international case-control study in the Democratic Republic of the Congo (133 cases, 301 controls), Vietnam (75 cases, 158 controls), the Philippines (102 cases, 152 controls), and Honduras (120 cases, 143 controls). Mothers were recruited from hospitals and their exposures were collected from interviewer-administered questionnaires. We used logistic regression modeling to estimate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Family history of clefts was strongly associated with increased risk (maternal: OR = 4.7; 95% CI, 3.0-7.2; paternal: OR = 10.5; 95% CI, 5.9-18.8; siblings: OR = 5.3; 95% CI, 1.4-19.9). Advanced maternal age (5 year OR = 1.2; 95% CI, 1.0-1.3), pregestational hypertension (OR = 2.6; 95% CI, 1.3-5.1), and gestational seizures (OR = 2.9; 95% CI, 1.1-7.4) were statistically significant risk factors. Lower maternal (secondary school OR = 1.6; 95% CI, 1.2-2.2; primary school OR = 2.4, 95% CI, 1.6-2.8) and paternal education (OR = 1.9; 95% CI, 1.4-2.5; and OR = 1.8; 95% CI, 1.1-2.9, respectively) and paternal tobacco smoking (OR = 1.5, 95% CI, 1.1-1.9) were associated with an increased risk. No other significant associations between maternal and paternal factors were found; some environmental factors including rural residency, indoor cooking with wood, chemicals and water source appeared to be associated with an increased risk in adjusted models. CONCLUSION: Our study represents one of the first international studies investigating risk factors for clefts among multiethnic underserved populations. Our findings suggest a multifactorial etiology including both maternal and paternal factors.

RESUMO

BACKGROUND AND OBJECTIVES: While treatment-induced tissue necrosis is a well-documented predictor of patient survival in malignant bone tumors, its prognostic value in soft tissue sarcomas is controversial. A prior study from our institution did not find a prognostic value to tumor necrosis. We analyze a more extensive database of high-grade soft tissue sarcomas treated with neoadjuvant chemotherapy, radiation therapy, or both to re-evaluate if the degree of tumor necrosis alone can be used as a predictive factor for local recurrence, metastasis, and disease-specific survival. METHODS: Two hundred and seven patients with high-grade extremity soft tissue sarcoma received neoadjuvant chemotherapy and/or radiation therapy and wide excision. Tumor treatment response was determined by histopathologic analysis, and patients were followed for local recurrence, metastasis, or death. RESULTS: Tumor necrosis ≥ 90% correlates with improved disease-free survival with univariate analysis, but this does not reach statistical significance on multivariate analysis. Age and tumor volume were found to be the only independent predictors of disease-free survival on multivariate analysis. CONCLUSIONS: There is insufficient evidence to support the use of necrosis to prognosticate survival and alter chemoradiation regimens in high grade soft tissue sarcomas of the extremity. Larger studies are needed to definitively address the prognostic value of necrosis. LEVEL OF EVIDENCE: Level II, Prognostic

RESUMO

BACKGROUND: As three-dimensional technology becomes more ubiquitous, many plastic surgical applications have emerged. The authors investigate a three-dimensional scanning and printing system for facial soft tissue reconstruction in conjunction with an anterolateral thigh dermal adipofascial flap for the treatment of Parry-Romberg syndrome. METHODS: Seven patients with facial atrophy of the zygomatic, buccal, and mandibular areas were included. Three-dimensional scanning of each patient's face in conjunction was analyzed with computer-aided design (CAD) to quantify areas of facial asymmetry. Models were then created using three-dimensional printing to map areas of soft tissue deficiency. Free anterolateral thigh (ALT) dermal adipofascial flaps were designed based on the three-dimensional models of soft tissue deficiency. RESULTS: All flaps survived. One case had a postoperative hematoma. Six patients had restored facial symmetry. One patient required fat injections to obtain symmetry. No patients required revision surgery of their healed flaps for contouring. CONCLUSIONS: Three-dimensional laser scanning and three-dimensional printing in combination with a free ALT dermal adipofascial flap offer surgeons a precise means to reconstruct facial contour deformities.

RESUMO

BACKGROUND: Regional and international cleft care providers are challenged in their ability to deliver reliable, comprehensive care. Our institution utilizes video teleconferencing to facilitate initial evaluation and postoperative cleft care. This study describes our experience using telemedicine, generates a perioperative treatment algorithm using this technology, and compares cost-utility of telemedicine to in-person ambulatory visits when regional practices are involved. METHODS: A 5-year retrospective review of all cleft patients evaluated in an ambulatory setting was conducted. Patient demographics and location, number, and type of telemedicine visits were recorded. Specific treatment algorithms utilizing telemedicine for perioperative care for primary and secondary cleft lip and nasal repair, palatoplasty, and operation for velopharyngeal insufficiency are described. A cost-utility analysis was performed comparing distances between patient homes and primary hub versus telemedicine clinic sites. RESULTS: Five hundred nineteen patients were identified; 18.1% attended at least 1 teleconferencing visit. Postoperative follow-up was 100%. The majority of screening, preoperative, and postoperative care was provided using telemedicine. In-person evaluations were performed when intraoral assessments were necessary. Telemedicine visits were associated with an average savings of 239 miles per visit in the United States and 578 miles per visit in Mexico. CONCLUSIONS: Video teleconferencing can be used to provide comprehensive regional and international cleft care to facilitate initial evaluations and consistent follow-up. This technology can alleviate the travel burden on families and cleft care providers practicing over a large geographic radius.

RESUMO

Genome-wide association studies (GWAS) for orofacial clefts have identified several susceptibility regions, but have largely focused on non-Hispanic White populations in developed countries. We performed a targeted genome-wide study of single nucleotide polymorphisms (SNPs) in exons using the Illumina HumanExome+ array with custom fine mapping of 16 cleft susceptibility regions in three underserved populations: Congolese (87 case-mother, 210 control-mother pairs), Vietnamese (131 case-parent trios), and Filipinos (42 case-mother, 99 control-mother pairs). All cases were children with cleft lip with or without cleft palate. Families were recruited from local hospitals and parental exposures were collected using interviewer-administered questionnaires. We used logistic regression models for case-control analyses, family-based association tests for trios, and fixed-effect meta-analyses to determine individual SNP effects corrected for multiple testing. Of the 16 known susceptibility regions tested, SNPs in four regions reached statistical significance in one or more of these populations: 1q32.2 (IRF6), 10q25.3 (VAX1), and 17q22 (NOG). Due to different linkage disequilibrium patterns, significant SNPs in these regions differed between the Vietnamese and Filipino populations from the index SNP selected from previous GWAS studies. Among Africans, there were no significant associations identified for any of the susceptibility regions. rs10787738 near VAX1 (P = 4.98E-3) and rs7987165 (P = 6.1E-6) were significant in the meta-analysis of all three populations combined. These results confirm several known susceptibility regions and identify novel risk alleles in understudied populations.

RESUMO

BACKGROUND: Humanitarian surgical organizations such as Operation Smile provide global health opportunities for students and medical trainees. Prior studies have shown a positive benefit for medical trainees. This study aimed to determine if the international global health experiences of young student volunteers impact their career choices as adults. METHODS: A survey was sent to adults who were involved with Operation Smile as students. The survey elicited information about their mission trip experience, education, career, and current volunteer and leadership activities. Data were summarized with descriptive statistics and qualitative analysis. RESULTS: 114 prior volunteers responded. The majority participated in leadership conferences (n = 110), mission trips (n = 109), and student clubs (n = 101) while in high school. Many graduated from college (n = 113, 99%) and completed post-graduate degrees (n = 47, 41%). The most highly represented occupational industry was healthcare (n = 30, 26%), including physicians and medical trainees (n = 9), dentists (n = 5), and other healthcare providers (n = 5). Three-fourths reported that their volunteer experience impacted their career choice, and half reported that their experience allowed them to connect with career mentors. Their experience was associated with the development of leadership skills, including public speaking, self-confidence, and empathy, and increased awareness of cleft conditions, health disparities, and other cultures. Ninety-six percent continued to volunteer. Narrative responses revealed that the volunteer experiences impacted their inter- and intrapersonal development into adulthood. CONCLUSIONS: Participation in a global health organization as a student may encourage a long-term commitment to leadership and volunteerism and foster interest in a healthcare career. These opportunities also encourage development of cultural competency and interpersonal skills. LEVEL OF EVIDENCE: III, Cross-Sectional Study.

RESUMO

Orofacial clefting is a common reconstructive surgical condition that often involves the palate. Cleft palate repair has evolved over three centuries from merely achieving anatomical closure to prioritizing speech development and avoiding midface hypoplasia. Despite centuries of advancements, there is still substantial controversy and variable consensus on technique, timing, and sequence of cleft palate repair procedures. Furthermore, evaluating the success of various techniques is hindered by a lack of universal outcome metrics and difficulty maintaining long-term follow-up. This article presents the current controversies of cleft palate repair and details how the history of cleft palate repair has influenced current techniques commonly used worldwide. Our review highlights the need for a global consortium on cleft care to gather expert opinions on current practices and outcomes and to standardize technique classifications. An understanding of global protocols is crucial in an attempt to standardize technique and timing to achieve anatomical closure with optimal velopharyngeal competence, while also minimizing the occurrence of maxillary hypoplasia and palatal fistulae.
