Incidência de complicações durante os anos iniciais de formação de um serviço de fissuras labiopalatinas / Incidence of complications during the initial years of formation of a cleft lip and palate service

Introdução: A fissura labiopalatina é a malformação congênita craniofacial mais comum. Dificuldades na alimentação, fala e audição são comuns nestes pacientes, necessitando de tratamento multidisciplinar, o que dificulta a criação e manutenção de serviços especializados. A diversidade de classificações e o grande número de técnicas cirúrgicas utilizadas nas cirurgias primárias (queiloplastia e palatoplastia) dificultam a comparação de dados epidemiológicos e de complicações entre os serviços, existindo carência de estudos avaliando centros especializados em fissuras labiopalatinas recém-criados. Método: Foi realizado estudo do tipo coorte prospectiva com pacientes com diagnóstico de fissura labiopalatina submetidos a procedimentos cirúrgicos primários, no Hospital de Clínicas da Universidade Federal de Uberlândia, entre julho de 2017 e fevereiro de 2023. Foram incluídos pacientes menores de 18 anos com acompanhamento pós-operatório de pelo menos 3 meses. Resultados: Participaram do estudo 79 pacientes, que foram submetidos a 115 cirurgias primárias (54 queiloplastias e 61 palatoplastias). Foram relatadas 11 complicações neste período: 2 deiscências em queiloplastia (3,70%), 1 cicatriz hipertrófica em queiloplastia (1,85%), 6 fístulas em palatoplastia (9,83%) e 2 deiscências em palatoplastia (3,28%). A incidência de complicações foi de 9,56% quando analisado o total de cirurgias, sendo 5,55% nos pacientes submetidos a queiloplastia e 13,11% nos pacientes submetidos a palatoplastia. Conclusão: A incidência de complicações durante os anos iniciais de estruturação do serviço foi semelhante a outros estudos da literatura.

Introduction: Cleft lip and palate is the most common congenital craniofacial malformation. Difficulties in eating, speaking, and hearing are common in these patients, requiring multidisciplinary treatment, which makes it difficult to create and maintain specialized services. The diversity of classifications and the large number of surgical techniques used in primary surgeries (cheiloplasty and palatoplasty) make it difficult to compare epidemiological data and complications between services, and there is a lack of studies evaluating newly created specialized centers for cleft lip and palate. Method: A prospective cohort study was carried out with patients diagnosed with cleft lip and palate who underwent primary surgical procedures at the Hospital de Clínicas of the Universidade Federal de Uberlândia, between July 2017 and February 2023. Patients under 18 years of age with follow-up were included. post-operative period of at least 3 months. Results: 79 patients participated in the study, who underwent 115 primary surgeries (54 cheiloplasties and 61 palatoplasties). 11 complications were reported in this period: 2 dehiscences in cheiloplasty (3.70%), 1 hypertrophic scar in cheiloplasty (1.85%), 6 fistulas in palatoplasty (9.83%) and 2 dehiscences in palatoplasty (3.28%). The incidence of complications was 9.56% when analyzing the total number of surgeries, being 5.55% in patients undergoing cheiloplasty and 13.11% in patients undergoing palatoplasty. Conclusion: The incidence of complications during the initial years of structuring the service was similar to other studies in the literature.

Prevalência de fissuras labiopalatais no Brasil e sua notificação no sistema de informação / Prevalence of cleft lip and palate in Brazil and its notification in the information system

Introdução: A fissura labiopalatina é a deformidade congênita mais comum, com uma incidência de 1,53/1000 nascidos vivos e o tratamento predominantemente realizado no Sistema Único de Saúde (SUS). Em 1999, o Sistema de Informações sobre Nascidos Vivos (SINASC) implantou a lacuna para preenchimento referente a deformidade congênita. Trabalhos vêm demostrando a subnotificação importante da fissura no SINASC. Método: Foi levantado o número de crianças nascidas por ano no Brasil entre 2012 e 2018 nas respectivas regiões, projetando o número de fissurados nascidos por ano usando a proporção 1,53/1000 nascidos vivos. A partir destes dados, observado o número de fissurados notificados no sistema SUS e comparado com a projeção feita observando uma estimativa de notificação por região. Verificada também a evolução dos gastos governamentais por região com cirurgia de fissura labiopalatina no período de 2012 a 2018. Resultados: Houve uma notificação de 54,1% a 36,7% das crianças nascidas com fissura, sendo a Região Sudeste com melhor índice e o Nordeste com o índice mais baixo de notificação. Os gastos federais em cirurgia de fissura labiopalatina diminuíram entre 2012 e 2018, frente ao número de nascimentos com fissuras, que se manteve estável neste período. Conclusão: Apesar do SINASC ser uma ferramenta importante, as subnotificações expressivas desta afecção impactam nas políticas públicas, pois utilizam dados inconsistentes com a realidade. Outra preocupação é a diminuição dos gastos federais com cirurgias de fissurados, o que demostra que mais crianças estão deixando de receber tratamento adequado.

Introduction: Cleft lip and palate is the most common congenital deformity, with an incidence of 1.53/1000 live births, and treatment is predominantly carried out in the Unified Health System (Sistema Único de Saúde SUS). In 1999, the Live Birth Information System (Sistema de Informações sobre Nascidos Vivos SINASC) implemented the gap to be filled in regarding congenital deformities. Studies have demonstrated the significant underreporting of the fissure in SINASC. Method: The number of children born per year in Brazil between 2012 and 2018 was surveyed in the respective regions, projecting the number of cleft children born per year using the proportion 1.53/1000 live births. From these data, the number of cleft patients notified in the SUS system was observed and compared with the projection made by observing an estimate of notification by region. The evolution of government spending by region on cleft lip and palate surgery in the period from 2012 to 2018 was also verified. Results: There was a notification of 54.1% to 36.7% of children born with cleft, with the Southeast Region having the best rate and the Northeast with the lowest notification rate. Federal spending on cleft lip and palate surgery decreased between 2012 and 2018, compared to the number of births with clefts, which remained stable during this period. Conclusion: Although SINASC is an important tool, the significant underreporting of this condition impacts public policies, as it uses data inconsistent with reality. Another concern is the decrease in federal spending on cleft surgery, which shows that more children are failing to receive adequate treatment.

Introduction: Cleft lip and palate (CLP) is a craniofacial alteration of multifactorial etiology. The diet of children with CLP can become deficient, compromising growth and development. Objective: To determine the evolution of the pre- and post-surgical nutritional status and feeding practices in infants between 6 and 24 months of age, with cleft lip and/or palate who attended the "Operation Smile" Foundation Clinic from September 2020 to May 2021. Materials and methods: This was an observational and prospective study with an analytical component. 50 children with a diagnosis of CLP from 6 to 24 months of age were included. Nutritional status was evaluated according to National Health Ministry standards. Results: 50 infants from 6 to 24 months were evaluated, 60% were between 6 -11 months, 64% were males, 54% came from the rural areas. 86% underwent primary lip closure and 12% cleft palate reconstruction. 88% of the children were breastfed. The pre-surgical nutritional status was adequate (94%) by weight for age indicator. Post surgery there was a significant difference of 0.927 kg for weight for height (p < 0.001), the same for weight for age (p < 0.001). For height for age, a difference of 0.8 cm was found (p=ns). Conclusions: The nutritional status of children with cleft lip or palate improves 4 months after reconstructive surgery for the indicators weight for age and weight for height.

Prevalência de anomalias dentárias e outros achados orais em radiografias panorâmicas de brasileiros com fissura labiopalatal: um estudo retrospectivo / Prevalence of dental anomalies and other oral findings on panoramic radiographs of Brazilian with cleft lip and palate: a retrospective study

Objetivo: avaliar a prevalência de anomalias dentárias (AD) e outros achados orais em radiografias panorâmicas de pacientes com fissuras labiopalatais (FLP) nascidos no Nordeste brasileiro. Métodos: a amostra foi composta por 69 pacientes com fissuras labiopalatais unilateral (FLPu) (n = 51) e bilateral (FLPb) (n = 18), não sindrômicos, de ambos os sexos, idade de 6 a 17 anos, nascidos no Nordeste brasileiro. Foram analisados prontuários e radiografias panorâmicas de pacientes atendidos de janeiro/2020 a julho/2022. Os dados categóricos foram expressos em forma de frequência absoluta e percentual e comparados por teste exato de Fisher ou qui-quadrado de Pearson (SPSS, p < 0,05). Resultados: entre os achados orais, destacaram-se as anomalias de número e as ausências dentárias por trauma, cárie ou doença periodontal. As AD foram identificadas em 34 pacientes (49,3%). As anomalias de número apresentaram maior prevalência, com diferença estatística significativa para pacientes FLPb do sexo masculino (p = 0,047). A agenesia foi a AD mais frequente (n = 24; 34,8%). As ausências dentárias por trauma, cárie ou doença periodontal foram observadas em 44 pacientes (n = 63,8%), com uma diferença estatística significativa entre os grupos FLPu e FLPb (p = 0,018). Conclusões: as AD e as ausências dentárias por trauma, cárie ou doença periodontal apresentaram uma alta prevalência entre pacientes brasileiros com FLP e devem ser consideradas durante o planejamento ortodôntico-cirúrgico desses indivíduos.

Aim: this study aimed to assess the prevalence of dental anomalies (DA) and other oral findings in panoramic radiographs of patients with cleft lip and palate (CLP) born in the Northeast region of Brazil. Methods: the sample consisted of 69 patients with unilateral cleft lip and palate (UCLP) (n = 51) and bilateral cleft lip and palate (BCLP) (n = 18), non-syndromic, of both genders, aged 6 to 17 years, born in the Brazilian Northeast. Patient records and panoramic radiographs from those treated between January 2020 and July 2022 were analyzed. Categorical data were expressed as absolute frequency and percentage and compared using Fisher's exact test or Pearson's chi-square test (SPSS, p < 0.05). Results: among oral findings, anomalies in number and tooth absences due to trauma, caries, or periodontal disease stood out. DAs were identified in 34 patients (49.3%). Anomalies in number showed higher prevalence, with a statistically significant difference for male BCLP patients (p = 0.047). Agenesis was the most frequent DA (n = 24; 34.8%). Tooth absences due to trauma, caries, or periodontal disease were observed in 44 patients (63.8%), with a statistically significant difference between the UCLP and BCLP groups (p = 0.018). Conclusions: DAs and tooth absences due to trauma, caries, or periodontal disease showed a high prevalence among Brazilian patients with CLP and should be considered during the orthodontic-surgical planning for these individuals.

Epidemiologic profile and prevalence of live births with orofacial cleft in Brazil: a descriptive study / Perfil epidemiológico e prevalência de nascidos vivos com fissura orofacial no Brasil: um estudo descritivo

ABSTRACT Objective: To describe the epidemiological profile and prevalence of live births with orofacial clefts in Brazil between 1999 and 2020. Methods: Descriptive study. The population corresponded to live births with isolated orofacial clefts in Brazil registered in the Live Birth Information System between 1999 and 2020. Descriptive variables were selected according to their availability and grouped into socioeconomic and demographic, maternal and child health care, and biological variables. Data were submitted to a descriptive analysis using the Software for Statistics and Data Science (STATA). Results: During the period, 33,699 children were born with orofacial clefts, and 82.1% (27,677) of them were isolated clefts. Regarding these cases, the majority were cleft lip and palate (9,619 or 34.7%), followed by cleft palate (9,442 or 34.1%), and by cleft lip (8,616 or 31.3%). Conclusions: Live births with orofacial clefts in Brazil were male, white, with birthweight ≥2,500 g and gestational age ≥37 weeks, born by cesarean section, and with Apgar scores ≥7. The cases were more frequent among mothers who were in their first and single pregnancy and had seven or more prenatal appointments. The mothers were 20 and 29 years old, had eight to ten years of study, and were single. The national prevalence of clefts was 4.24/10,000. The South and Southeast regions of Brazil had the highest prevalence, while the lowest prevalence was recorded in the Northeast and North regions. For the Federative Units, the highest and lowest prevalences were found, respectively, in Paraná and Acre.

Biomechanical behavior of three maxillary expanders in cleft lip and palate: a finite element study

Abstract: This study evaluated the stress distribution in the dentoalveolar and palatal bone structures during maxillary expansion in a 17-year-old male patient with bilateral cleft lip and palate (BCLP) using expanders with dental (HYRAX) and skeletal anchorage (MARPE). For the generation of the specific finite element models, cone-beam computed tomography was used, and the DICOM files were exported to Mimics 3-Matic (Materialise) and Patran (MSC Software) software. Three specific three-dimensional models were generated: A) HYRAX: conventional four-banded hyrax screw (9 mm); B) MARPE-DS: 3 miniscrews (1.8 mm diameter - 5.4 mm length) and four-banded dental anchorage; and C) MARPE-NoDS: 3 miniscrews without dental anchorage. Maxillary expansion was simulated by activating the expanders transversely 1 mm on the "X" axis. HYRAX resulted in higher levels of deformation predominantly in the dentoalveolar region. MARPE-DS showed stress in the dentoalveolar region and mainly in the center of the palatal region, at approximately 4,000 με. MARPE-NoDS exhibited evident stress only in the palatal region. High stress levels in the root anchoring teeth were observed for HYRAX and MARPE-DS. In contrast, MARPE-NoDS cause stress on the tooth structure. The stress distribution from the expanders used in the BLCP showed asymmetric expansive behavior. During the initial activation phase of expansion, the HYRAX and MARPE-DS models produced similarly high strain at the dentoalveolar structures and upper posterior teeth displacement. The MARPE-NoDS model showed restricted strain on the palate.

Exposición a ondansetrón en el primer trimestre de gestación y riesgo de malformaciones congénitas: revisión sistemática y metaanálisis / Exposure to ondansetron in the first trimester of pregnancy and risk of congenital malformations: systematic review and meta-analysis

Resumen OBJETIVO: Determinar si la exposición al ondansetrón en el primer trimestre del embarazo se asocia, en general, con mayor riesgo de malformaciones orofaciales, cardiopatías congénitas, defectos del septo interventricular, de labio o paladar hendidos. MÉTODOLOGÍA: Revisión sistemática y metanálisis de estudios aleatorizados, cohortes y casos y controles publicados en las bases de datos de PubMed, EMBASE y LILACS. RESULTADOS: Se incluyeron 15 estudios: 11 de cohorte y 4 de casos y controles, con 245,679 mujeres expuestas al ondansetrón en el primer trimestre del embarazo. No se encontró una asociación estadísticamente significativa con malformaciones congénitas en general (RM 1.1; IC95%: 0.99-1.22; I2: 72%), con cardiopatías congénitas (RM 1.05; IC95%: 0.95-1.19; I2: 78%) y con comunicación interventricular (RM 1.2; IC95%: 0.97-1.45; I2: 85%). Se encontró un pequeño aumento en el riesgo de defectos orofaciales en general (RM 1.17; IC95%: 1.04-1.32; I2:0%), no se encontró un riesgo mayor de defecto de labio (RM 1.01; IC95%: 0.84-1.21; I2%: 0%) ni de paladar hendido (RM 1.16; IC95%: 0.9-1.5; I2: 31%). CONCLUSIÓN: Los resultados muestran que el tratamiento con ondansetrón en el primer trimestre del embarazo no se asocia con un aumento de malformaciones congénitas en general, ni con un incremento de cardiopatías, labio o paladar hendido, pero sí con incremento leve del riesgo de malformaciones orofaciales.

Abstract OBJECTIVE: To determine whether ondansetron exposure in the first trimester is associated with an increased risk of any congenital malformations. As secondary outcomes, determine if it is associated with a higher overall risk of congenital heart disease, interventricular septal defects, orofacial malformations, cleft lip defect (with or without palate) or cleft palate. METHODOLOGY: A systematic review with meta-analysis was carried out. The search was carried out in the following databases: PUBMED, EMBASE and LILACS, randomized studies, cohorts and cases and controls were chosen. RESULTS: 15 studies were included, 11 cohort studies and four case-control studies, with 245,679 women exposed to ondansetron in the first trimester. No statistically significant association was found with overall congenital malformations (OR, 1.1; 95%, CI 0.99-1.22 I2: 72%), nor with congenital heart diseases (OR, 1.05; 95%, CI 0.95-1.19 I2: 78%) not with ventricular septal defects (OR, 1.2 95% CI 0.97 - 1.45 I2: 85%). A small increased risk was found for overall orofacial defects (OR, 1.17 95% CI 1.04 - 1.32 I2:0%), no increased risk was found for lip defect (with or without palate) (OR, 1.01 CI 95% 0.84 -1.21 I2%: 0%) or cleft palate (OR, 1.16 95% CI 0.9 - 1.5 I2: 31%). CONCLUSION: The results show that the use of ondansetron in the first trimester is not associated with an increase in overall congenital malformations, nor with an increase in heart disease, cleft lip and/or palate, but there is a slight increase in the risk of orofacial malformations.

History of Eugenics in Otorhinolaryngology: Ernst Rüdin and the International Eugenics Network

Abstract Introduction The early geneticist and psychiatrist Ernst Rüdin (1874-1952) became one of the key figures in the eugenics movement and in the German health system of the Nazi era. His connections in the international eugenics network have played an important role in the history of eugenics. Objective To discuss the connections between Ernst Rüdin's scientific group in Munich and Otmar von Verschuer's group in Frankfurt during the Nazi era. Methods Otorhinolaryngological materials from Ernst Rüdin's former private library are presented, and they show Rüdin's deep involvement in the international eugenics network. These materials provide insights into early medical genetics in otorhinolaryngology. Results One result of the present study is that eugenics groups from Munich, Frankfurt, and New York certainly influenced one another in the field of otorhinolaryngology. Karlheinz Idelberger and Josef Mengele were two scientists who performed hereditary research on orofacial clefts. Later, Mengele became deeply involved in Nazi medical crimes. His former work on orofacial clefts clearly had, to some extent, an influence on subsequent studies. Conclusion An international eugenics network already existed before 1933. However, it becomes clear that the weaknesses of many early genetic studies did not enable its authors to draw firm scientific conclusions, suggesting that scientists lacked an accurate concept of the genetic causes of most illnesses.

Adolescents with orofacial clefts: understanding their experiences / Adolescentes com fissura orofacial: compreendendo suas experiências

ABSTRACT Objective: To understand the experience of young people with orofacial clefts regarding life as an adolescent. Methods: Descriptive, qualitative study, developed in a Brazilian public and tertiary hospital, a reference center in the care of patients with craniofacial anomalies and related syndromes, between February and April 2019. The sample was defined by theoretical saturation. The following inclusion criteria were established: age between ten and 19 years old and having previously operated on orofacial cleft (lip and/or palate). Individuals with fissure associated with syndromes or other malformations were excluded. Data collection was performed through semi-structured interviews, which were audio recorded and transcribed in full. The trigger element was: how has it been for you to experience your adolescence? For the construction of the results, content analysis was used in the thematic modality. Results: Seventeen adolescents participated. From the speeches, three categories were revealed: interacting socially, feeling supported, and experiencing and facing prejudice. Conclusions: The biopsychosocial and conflicting complexity that adolescents with orofacial clefts experience was noticed, as well as the importance of receiving support and establishing modalities of situational coping.

RESUMO Objetivo: Compreender a experiência de jovens com fissura orofacial quanto à vivência da adolescência. Métodos: Estudo descritivo, qualitativo, desenvolvido em um hospital público e terciário brasileiro, referência no atendimento de pacientes com anomalias craniofaciais e síndromes relacionadas, entre fevereiro e abril de 2019. A amostra foi definida por saturação teórica. Estabeleceram-se como critérios de inclusão: idade compreendida entre dez e 19 anos completos e apresentação de fissura orofacial (lábio e/ou palato) previamente operada. Excluíram-se aqueles que apresentavam a fissura associada a síndromes ou outras malformações. A coleta de dados foi realizada por meio de entrevista semiestruturada, que foi gravada em áudio e transcrita na íntegra. O elemento disparador foi: como tem sido para você vivenciar sua adolescência? Para a construção dos resultados, utilizou-se a análise de conteúdo na modalidade temática. Resultados: Participaram 17 adolescentes. Com base nos discursos, desvelaram-se três categorias: interagindo socialmente; sentindo-se apoiado; e vivenciando e enfrentando o preconceito. Conclusões: Percebeu-se a complexidade biopsicossocial e conflituosa que adolescentes com fissura de orofacial vivenciam, assim como a importância de eles receberem apoio e de se estabelecerem modalidades de enfrentamento situacional.

ENAM gene polymorphisms associated with dental anomalies in individuals with cleft lip and palate

Aim: This study aimed to investigate the occurrence of enamelin gene (ENAM) single nucleotide polymorphisms (SNP) and ENAM polymorphism association with dental anomalies (DA) in individuals with unilateral or bilateral cleft lip and palate (CLP). Methods: Saliva samples were collected from 147 individuals aged between 6 and 15 years-old, both genders, and divided into 4 groups: Group 1 (G1) - CLP and DA; Group 2 (G2) - CLP without DA; Group 3 (G3) - without CLP with DA; Group 4 (G4) - without CLP and DA. The genomic DNA was extracted from saliva samples and the following ENAM SNPs markers were genotyped: rs3796703, rs3796704, rs3796705, rs7671281, rs2609428, and rs35951442. Fisher exact and Pearson's Chi-square tests statistically analyzed the results (α=5%). Results: Individuals without CLP with DA (Group 3 - 19.2%) showed statistically higher prevalence of SNP rs2609428 heterozygotes (p=0.006) than individuals with CLP and DA (Group 1 - 0%). Individuals without CLP (10%) exhibited statistically higher prevalence of mutated heterozygotes/homozygous (p=0.028) than in individuals with CLP (1.3%). Conclusion: SNP rs2609428 marker of ENAM gene may be associated with dental anomalies in individuals without cleft lip and palate

Abstract Objective to understand the therapeutic itinerary of children with cleft lip and/or palate. Method a descriptive qualitative study carried out with families of children with cleft lip and palate. Data collection took place between June and July 2022 through semi-structured interviews, and thematic content analysis was applied. Results eight families participated and three categories emerged: I) Facing the unknown: diagnosis of cleft lip and palate in children - feelings of shock, fear and uncertainty were noted that permeate during early or late diagnosis; II) An arduous path: pauses and beginnings during the therapeutic itinerary - it was observed that the families followed different paths due to the specificity of the family configuration and the cleft itself; III) Weaving the support network for care - support from friends, family, professionals and health institutions proved to be extremely necessary. Conclusions and implications for practice the therapeutic itinerary of children with cleft lip and palate is arduous and followed by challenges, which begin at diagnosis and continue after birth. It is hoped that the results of this study will encourage dialogue among health professionals and become familiar with the needs of this population and be able to act at different points of health care.

Evaluation of facial pleasantness in patients with complete and unilateral cleft lip and palate rehabilitated and submitted to orofacial harmonization

ABSTRACT Objective: The objective of the present prospective case control study was to evaluate the facial pleasantness of patients with complete and unilateral cleft lip and palate at the end of interdisciplinary rehabilitation, submitted to facial fillers based on hyaluronic acid. Methods: The study group consisted of 18 individuals with complete unilateral cleft lip and palate, aged between 18 and 40 years (mean age 29 years) of both sexes. The patients presented a concave profile with mild to moderate maxillary deficiency, with completed orthodontic treatment and conducted by means of dentoalveolar compensations without orthognathic surgery. Participants underwent facial filling procedures with hyaluronic acid (HA) in the midface, inserted by a single operator. Standard photographs in frontal norm at rest, right profile at rest, and left profile at rest were obtained from each patient at the following operative times: (T1) pre-filler and (T2) and one-month post-filler. The photographs in T1 and T2 were randomly placed on a page of a virtual album. A 5-point Likert scale was used to assess facial pleasantness. The photographs were evaluated by two groups of evaluators consisting of 18 individuals with cleft lip and palate (CLPG=18) and 18 orthodontists with experience in the treatment of clefts (OG=18). For comparison between phases T1 and T2, and between evaluators with orofacial clefts and orthodontists, the Wilcoxon test was used (p<0,05). Results: People with cleft lip and palate rated their face as more pleasant after the midface filling procedure. In the perception of the orthodontists, on the other hand, the facial pleasantness remained similar after the facial filling procedure. Conclusions: The filling of the middle third of the face in patients with cleft lip and palate treated without orthognathic surgery increased the pleasantness of the face in the opinion of laypeople with cleft lip and palate.

RESUMO Objetivo: O objetivo do presente estudo caso-controle prospectivo foi avaliar a agradabilidade facial de pacientes com fissura labiopalatina completa e unilateral ao final da reabilitação interdisciplinar, submetidos a preenchimentos faciais à base de ácido hialurônico. Métodos: O grupo de estudo foi composto por 18 indivíduos com fissura labiopalatina unilateral completa, com idade entre 18 e 40 anos (média de 29 anos), de ambos os sexos. Os pacientes apresentavam perfil côncavo com deficiência maxilar leve a moderada, com tratamento ortodôntico concluído e realizado por meio de compensações dentoalveolares sem cirurgia ortognática. Os participantes foram submetidos a procedimentos de preenchimento facial com ácido hialurônico (AH) no terço médio da face, implantado por um único operador. Fotografias padrão em norma frontal em repouso, perfil direito em repouso e perfil esquerdo em repouso foram obtidas de cada paciente nos seguintes tempos operatórios: (T1) pré-preenchimento e (T2) um mês pós-preenchimento. As fotografias em T1 e T2 foram inseridas aleatoriamente em uma página de um álbum virtual. Uma escala Likert de 5 pontos foi utilizada para avaliar a agradabilidade facial. As fotografias foram avaliadas por dois grupos de avaliadores formados por 18 indivíduos com fissura labiopalatina (GFLP=18) e 18 ortodontistas com experiência no tratamento de fissuras (GO=18). Para comparação entre as fases T1 e T2, e entre avaliadores com fissura labiopalatina e ortodontistas, foi utilizado o teste de Wilcoxon (p<0,05). Resultados: As pessoas com fissura labiopalatina avaliaram seu rosto como mais agradável após o preenchimento do terço médio da face. Já na percepção do ortodontista, a agradabilidade facial permaneceu semelhante após o procedimento de preenchimento facial. Conclusões: O preenchimento do terço médio da face em pacientes com fissura labiopalatina tratados sem cirurgia ortognática aumentou a agradabilidade da face na opinião dos leigos com fissura labiopalatina.

Exploring the role of the WNT5A rs566926 polymorphism and its interactions in non-syndromic orofacial cleft: a multicenter study in Brazil

Abstract Associations between the WNT5A rs566926 variant and non-syndromic orofacial cleft (NSOC) have been reported in different populations. Objective This study aimed to investigate the role of the rs566926 single nucleotide polymorphism (SNP) in WNT5A and its interactions with SNPs in BMP4, FGFR1, GREM1, MMP2, and WNT3 in the occurrence of NSOC in a Brazilian population. Methodology A case-control genetic association study was carried out involving participants from four regions of Brazil, totaling 801 patients with non-syndromic cleft lip with or without cleft palate (NSCL±P), 273 patients with cleft palate only (NSCPO), and 881 health volunteers without any congenital condition (control). Applying TaqMan allelic discrimination assays, we evaluated WNT5A rs566926 in an ancestry-structured multiple logistic regression analysis, considering sex and genomic ancestry as covariates. Interactions between rs566926 and variants in genes involved in the WNT5A signaling pathway (BMP4, FGFR1, GREM1, MMP2, and WNT3) were also explored. Results WNT5A rs566926 was significantly associated with an increased risk of NSCL±P, particularly due to a strong association with non-syndromic cleft lip only (NSCLO), in which the C allele increased the risk by 32% (OR: 1.32, 95% CI: 1.04-1.67, p=0.01). According to the proportions of European and African genomic ancestry, the association of rs566926 reached significant levels only in patients with European ancestry. Multiple interactions were detected between WNT5A rs566926 and BMP4 rs2071047, GREM1 rs16969681 and rs16969862, and FGFR1 rs7829058. Conclusion The WNT5A rs566926 polymorphism was associated with NSCL±P, particularly in individuals with NSCLO and high European ancestry. Epistatic interactions involving WNT5A rs566926 and variants in BMP4, GREM1, and FGFR1 may contribute to the risk of NSCL±P in the Brazilian population.

Preoperative quality of life of patients with cleft lip and palate in Nigeria: a multicentre cross-sectional pilot study

Introduction: the objective of this study was to determine the quality of life (QOL) of the patient with a cleft lip or palate scheduled for surgery. Methods: this analytic multicenter cross-sectional study involved six participating Smile Train Partner Hospitals from five geopolitical zones of the country and three major ethnic groups. Patients with cleft lip or cleft palate aged between 8 to 29 years scheduled for repair were recruited. The main outcome measure was quality of life scores as measured by cleft Q. Results: thirty-four (females 18, males 16) patients were scheduled for surgery of either cleft lip n=7 (20.6%) or cleft palate n=27 (79.4). Patients scheduled for primary surgeries were more than those for secondary surgeries, 23 (68.7%) vs 10 (30.3%). Of the QOL scales, the speech distress score was the least (56.0 ± 22.6) and the psychological score highest (73.9 ± 15.8). All QOL mean scores except the psychological score fell below normative cleft Q scores. The psychological scores in males (80.9 ± 16.2) were significantly higher than in females (67.7 ± 12.9, p=0.01). Patients for lip repair had lower psychological scores than those for palatal repair (median=59 vs 73, p=0.01). Patients for palate repair demonstrated significantly lower speech function and distress scores than those for lip repair (p=0.01, p<0.01 respectively). Conclusion: most of the QOL measures in patients with cleft lip and palate in this study fell below normative values. Gender and cleft type affect the quality of life. A larger study is recommended to establish national normative data.

Effectiveness of comprehensive rhinoplasty on secondary nasal deformity with saddle nasal deformity after cleft lip surgery / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery.@*METHODS@#The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation.@*RESULTS@#All patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones ( P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied.@*CONCLUSION@#Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.

Evaluation of Anaesthetic Challenges in Primary Cleft Lip and Palate Surgeries in a Single Center Study

Background: One of the most prevalent congenital malformations and the most frequent craniofacial defects in children is cleft lip and palate. The aim of the study was to investigate the anaesthetic procedures employed and to determine the challenges and postoperative complications associated with cleft lip and palate surgery. Material & Methods: A retrospective review of the anaesthetic procedures carried out from January 2022 to December 2022 at the Dhaka Dental College and Hospital. The hospital records were reviewed in order to learn about every occurrence of orofacial cleft surgery. In this study, a total number of 120 cases were reviewed. Results: Among 120 cases, 53 (44.2%) of the patients were female and 67 (55.8%) were male. The bulk of patients came after their first year of life. About 54(45%) of them were younger than five years old. 68(56.67%) underwent cleft lip surgery, 37(30.83%) for cleft palate surgery and rest 15(12.5%) patients under went for combined cleft lip and cleft palate surgeries. Upper Respiratory Tract Infection (URTI) was reported as the most common pre-existing morbidity. Bronchospasm was the main intraoperative complications occurred in 8 (6.67%) of the cases with URTI. After surgey 6(5%) patients experienced bleeding, 3(2.5%) patients needed to be reintubated. In addition, 2 (1.67%) instances had trouble controlling their pain, only 1(0.83%) patient had trouble swallowing and 1(0.83%) recovered slowly. Conclusion: Anaesthesia for surgical repair of cleft lip or palate in children is challenging. After a thorough preoperative evaluation, a trained anaesthesiologist should administer anaesthesia under strict supervision to minimize postoperative complications.

Investigación en fisuras faciales: quo vadis España? / Investigation in facial fissures: quo vadis Spain?

Las fisuras orofaciales representan un grupo heterogéneo de malformaciones congénitas que afectan a distintas estructuras de la cavidad oral y de la cara. Globalmente, los bebés con estos trastornos presentan una mayor morbilidad y mortalidad a lo largo de su vida en comparación con individuos no afectados. Por ello, los avances en la investigación biomédica resultan ineludibles. Así, el objetivo general de este trabajo fue llevar a cabo una revisión bibliográfica para analizar narrativamente los 10 principales estudios primarios sobre fisuras orofaciales llevados a cabo en España, publicados del 2018 hasta la actualidad. Según esto, a nivel institucional, destaca la Universidad Complutense de Madrid (UCM) con cuatro artículos publicados por el grupo de investigación UCM 920202. También sobresale la Universidad Rey Juan Carlos de Madrid, con tres artículos relacionados con diferentes aspectos de la personalidad y la calidad de vida de los pacientes fisurados, así como otras muchas variables cognitivo-emocionales. En relación con la Universidad de Valencia, encontramos dos artículos llevados a cabo en amplias muestras de pacientes con fisuras. Por último, en Barcelona resulta destacable un estudio observacional sobre problemas otorrinolaringológicos en pacientes operados de fisura palatina. En conclusión, si bien en los últimos años se han publicado varios artículos sobre distintos aspectos relacionados con las fisuras, aún queda mucho trabajo por hacer. España debería seguir potenciando proyectos con líneas de trabajo centradas en estas alteraciones del desarrollo craneofacial. Se necesitan estudios amplios, multicéntricos y colaborativos, para ahondar en los mecanismos etiológicos y, en última instancia, en las posibles herramientas para su prevención. Del mismo modo, se necesitan ayudas para dilucidar mejor las cuestiones relacionadas con los tratamientos en todas las dimensiones de la salud, preferentemente a partir de ensayos clínicos controlados aleatorizados, que faciliten la traslación de conocimientos y su accesibilidad universal dentro del sistema sanitario público español.

SUMMARY: Orofacial clefts represent a heterogeneous group of congenital malformations affecting different structures of the oral cavity and face. Overall, infants with these disorders have a higher lifetime morbidity and mortality compared to unaffected individuals. Therefore, advances in biomedical research are unavoidable. Thus, the overall objective of this work was to conduct a literature review to narratively analyse the 10 main primary studies on orofacial clefts carried out in Spain, published from 2018 to date. According to this review, at an institutional level, the Complutense University of Madrid (UCM) is notable with 4 articles published by the UCM 920202 research group. The Rey Juan Carlos University of Madrid also stands out, with three papers related to different aspects of the personality and quality of life of cleft patients, as well as many other cognitive-emotional variables. In relation to the University of Valencia, we found two studies carried out on large samples of cleft patients. Finally, in Barcelona, an observational study on otorhinolaryngological problems in cleft palate patients is noteworthy. In conclusion, although several studies have been published in recent years on different aspects related to clefts, there is still much work to be done. Spain should craniofacial development. Large, multicenter and collaborative studies are needed to delve deeper into the aetiological mechanisms and, ultimately, into the possible tools for their prevention. Similarly, support is needed to better elucidate questions related to treatments in all dimensions of health, preferably randomised controlled clinical trials, which facilitate the transfer of knowledge and its universal accessibility within the Spanish public health system.

Application of data mining to extract knowledge about the occurrence of fistulas after palatoplasty / Aplicação de mineração de dados para extração de conhecimento sobre ocorrência de fístulas após palatoplastia

Introduction: Data mining techniques expand access to important information for the decision-making process during health care. The objective the study proposes using data mining techniques to identify variables (surgical treatment protocols, patient characteristics, post-surgical complications) associated with fistulas after primary palatoplasty in patients with unilateral transforamen incisor cleft (UTIC). Method: A data set of 222 patients with UTIC without syndromes, operated by four surgeons with Furlow's or von Langenbeck's primary palatoplasty techniques, was analyzed for this study. Two models for detecting the outcome of surgery were induced using data mining techniques (Decision Tree and Apriori). Results: Five rules were selected from a decision tree pointing to some variables as predictors of fistulas associated with primary palatoplasty: infection, cough, hypernasality, and surgeon. Analysis of the model indicates that it correctly classifies 95.9% of occurrences between the absence and presence of fistulas. The second model indicates that the absence of post-surgical complications (infection and fever) and normal speech results (absent hypernasality, without suggestive of velopharyngeal dysfunction) are related to the absence of fistulas. Regarding surgical procedures, the Furlow technique and the Vomer flap were more frequent in patients with fistulas. Conclusion: Data mining techniques, as applied in the present study, pointed to infection and cough, hypernasality, and surgeon and surgical techniques as predictors of fistulas related to primary palatoplasty.

Introdução: As técnicas de mineração de dados ampliam o acesso a informações importantes para o processo de tomada de decisão durante os cuidados com a saúde. O objetivo do estudo propõe a utilização de técnicas de mineração de dados para identificar variáveis (protocolos de tratamento cirúrgico, características do paciente, intercorrências pós-cirúrgicas) associadas à ocorrência de fístulas após palatoplastia primária em pacientes com fissura transforame incisivo unilateral (FTIU). Método: Um conjunto de dados de 222 pacientes com FTIU sem síndromes, operados por quatro cirurgiões com as técnicas de palatoplastia primária de Furlow ou von Langenbeck, foi analisado para este estudo. Dois modelos para detecção do resultado da cirurgia foram induzidos usando técnicas de mineração de dados (Árvore de Decisão e Apriori). Resultados: Cinco regras foram selecionadas de uma árvore de decisão apontando para algumas variáveis como preditivas de fístulas associadas à palatoplastia primária: infecção, tosse, hipernasalidade, cirurgião. A análise do modelo indica que ele classifica corretamente 95,9% das ocorrências entre ausência e presença de fístulas. O segundo modelo indica que a ausência de intercorrências pós-cirúrgicas (infecção e febre) e resultado de fala normal (hipernasalidade ausente, sem sugestivo de disfunção velofaríngea) estão relacionados à ausência de fístulas. Em relação aos procedimentos cirúrgicos, o uso da técnica de Furlow e retalho de Vomer foram mais frequentes nos pacientes com fístulas. Conclusão: Técnicas de mineração de dados, conforme aplicadas no presente estudo, apontaram para infecção e tosse, presença de hipernasalidade, cirurgião e técnica cirúrgica como preditores de fístulas relacionadas à palatoplastia primária.
