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.

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.

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.

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.

Brown tumors of the jaw: an atypical manifestation of primary hyperparathyroidism / Tumores pardos de mandíbula: una manifestación atípica de hiperparatiroidismo primario

Abstract Brown tumors represent the terminal stage of bone remodeling processes in primary hyperparathyroidism. Currently they are rare, and typically affect long bones, pelvis and ribs. Brown tumors may be not included in the initial differential diagnosis of bone disease, espe cially when they are present in atypical localizations. We reported two cases of oral brown tumors as the initial presentation of primary hyperparathyroidism. In the first case, a 44-year-old woman presented a painful and sessile lesion of 4x3 cm over the central body of the mandible which progressively increased in 4-month. The second case involved a 23-year-old woman who was referred with a 3-month history of a painful and ulcerated mass of 2 cm arising from left maxilla, episodes of gingival hemorrhage and difficulty of breathing. Both cases were solitary tumors with no evidence of palpable cervical lymphadenopathy. Incisional biopsy of oral tumors resul ted in giant cell and primary hyperparathyroidism was confirmed by laboratory tests. After parathyroidectomy, histology confirmed adenoma in both cases. Although this type of clinical presentation has almost disappeared in the recent decades, brown tumors should be consi dered in the differential diagnosis of bone oral masses.

Resumen Los tumores pardos son raros y, por lo general, afectan huesos largos, pelvis y costillas. Pueden no estar incluidos en el diagnóstico diferencial inicial como manifestación de enfermedad esquelética, es pecialmente cuando se presentan en localizaciones atípicas. Comunicamos dos casos de tumores pardos orales como presentación inicial de hiperparatiroidismo primario. En el primer caso, una mujer de 44 años presentó una lesión dolorosa y sésil de 4 × 3 cm sobre el cuerpo central de la mandíbula que aumentó de tamaño progresivamente en 4 meses. El segundo caso corresponde a una mujer de 23 años que acudió por presentar una masa dolorosa y ul cerada de 2 cm en maxilar izquierdo de 3 meses de evolución, episodios de hemorragia gingival y difi cultad para respirar. Todos fueron tumores solitarios sin evidencia de linfadenopatía cervical palpable. La biopsia incisional de los tumores orales resultó en células gigantes, y las pruebas de laboratorio confirmaron el hiperparatiroidismo primario. Tras la paratiroidectomía, la histología confirmó adenoma en ambos casos. Los tumores pardos representan la etapa terminal de los procesos de remodelación ósea en el hiperparatiroidismo primario. Aunque este tipo de presentación clínica casi ha desaparecido en las últimas décadas, los tumores pardos deben ser considerados en el diagnóstico diferencial de las masas óseas orales.

Pleomorphic Adenoma of the Hard Palate: A Multidisciplinary Approach

Pleomorphic adenoma is the most common salivary gland tumor accounting for 80% of all major salivary gland tumors. It is a benign salivary gland neoplasm that constitutes 3% to 10% of the neoplasms in the head and neck region.1 Salivary gland neoplasms represents less than 1% of all tumors. This article is being showcased as a special case due to the fact it was done at a Taluk Hospital and also because ENT and oromaxillofacial surgeons were involved during the surgery.

Proposal for the Modification of the Method to Evaluate the Midpalatal Suture Maturation Status / Proposta de Modificação do Método para Avaliação do Status da Sutura Palatina Mediana

The objective of present research was to propose a new definition for the midpalatal suture (MPS) maturational stages through reevaluation of intermediate stages B, C and D. The sample was composed by 158 cone-beam computed tomography (CBCT) of individuals between 11 and 20 years of age (±15.4 years, 86 females and 71 males), divided into two groups: 74 individuals aged 11-15 years and 84 individuals aged 16-20 years. The CBCT scans were applied to evaluate midpalatal suture maturation status and comprised stages previously classified as B (29), C (92) and D (37). Each axial image was subdivided into six parts in the anteroposterior direction, and each portion was classified according to MPS maturational evaluation methodology. New definitions of stages were proposed. The reliability of the method was tested by two examiners and the intra- and inter-examiner concordances were defined for each evaluation through weighted kappa coefficients and 95% confidence intervals. The chi-square test was used to compare the groups. In all statistical tests, a significance level of 5% was adopted. Two new maturational stages were defined: sub-stage C- and sub-stage C+, with prevalence of 12% and 8.9%, respectively, in 11 to 20-year-olds. The redefinition and validation of the maturational stages of MPS, considering the sub-stages C- and C+, may allow to elucidate the difference in the prognosis of Rapid Maxillary Expansion among individuals aged 11 to 20 years. This data should be confirmed through a clinical study.(AU)

O objetivo da presente pesquisa foi propor uma nova definição para os estágios maturacionais da sutura palatina média (MPS) por meio da reavaliação dos estágios intermediários B, C e D. A amostra foi composta por 158 tomografias computadorizadas de feixe cônico (TCFC) de indivíduos entre 11 e 20 anos de idade (±15,4 anos, 86 do sexo feminino e 71 do sexo masculino), divididos em dois grupos: 74 indivíduos de 11 a 15 anos e 84 indivíduos de 16 a 20 anos. Os exames de TCFC foram aplicados para avaliar o estado de maturação da sutura palatina média e compreenderam os estágios previamente classificados como B (29), C (92) e D (37). Cada imagem axial foi subdividida em seis partes no sentido anteroposterior, e cada porção foi classificada de acordo com a metodologia de avaliação maturacional MPS. Novas definições de estágios foram propostas. A confiabilidade do método foi testada por dois examinadores e as concordâncias intra e interexaminadores foram definidas para cada avaliação por meio de coeficientes kappa ponderados e intervalos de confiança de 95%. O teste do qui-quadrado foi utilizado para comparar os grupos. Em todos os testes estatísticos adotou-se o nível de significância de 5%. Dois novos estágios maturacionais foram definidos: subestágio C- e subestágio C+, com prevalência de 12% e 8,9%, respectivamente, em jovens de 11 a 20 anos. A redefinição e validação dos estágios maturacionais da MPS, considerando os subestágios C- e C+, podem permitir elucidar a diferença no prognóstico da Expansão Rápida da Maxila entre indivíduos de 11 a 20 anos. Esses dados devem ser confirmados por meio de um estudo clínico.(AU)

Escaneamento intraoral como ferramenta de identificação humana através das rugosidades palatinas / Intraoral scanning as a tool for human identification through palatal roughness

A rugoscopia palatina analisa os padrões das rugas e suas características para cada indivíduo, podendo auxiliar a odontologia forense na identificação humana. Apesar de ser um método descrito na literatura a certo tempo, ainda existem poucos estudos utilizando imagens digitais. O objetivo deste estudo foi verificar a viabilidade da rugoscopia palatina através do método digital. Foram recrutados 30 alunos matriculados no curso de odontologia da Universidade São Francisco, mediante autorização do comitê de ética em pesquisa. A pesquisadora 1 realizou o escaneamento intraoral da arcada superior dos voluntários e o processamento e identificação dos modelos, dividindo-os em grupo A, composto pelo arco superior completo identificado de 1 a 30 e B pelo recorte da região de interesse, anterior e média do palato, enumerado de 1' a 30', os números foram dispostos de forma aleatória e registrados em uma tabela. Por se tratar de um estudo cego, a pesquisadora 2 só participou da segunda fase da pesquisa, exportando os modelos digitais em um software para analisar e classificar as rugas palatinas. A pesquisadora 2 realizou o levantamento total de rugas por indivíduo e correlacionou os modelos do grupo A com os do grupo B, obtendo um resultado de 100% de acertos. A análise do padrão de rugas é confiável, precisa e vantajosa, porém padronizar a classificação facilitaria sua reprodutibilidade. Tendo em vista o aumento do uso de tecnologias na odontologia, sugere-se que o método digital seja a linha de primeira escolha para o processo de identificação

Palatal rugoscopy analyzes the wrinkle patterns and their characteristics for each individual, and can assist forensic odontology in human identification. Despite being a method described in the literature for some time, there are still few studies using digital images. The aim of this study was to verify the feasibility of palatal rugoscopy using the digital method. Thirty students enrolled in the dentistry course at University of São Francisco were recruited, with the consent of the ethics in research committee. Researcher 1 performed the intraoral scanning of the upper arch of the volunteers and the processing and identification of the models, dividing them into group A, composed of the complete upper arch identified from 1 to 30, and B for the region of interest, anterior and midpalate, numbered from 1' to 30', the numbers were randomly arranged and recorded in a table. Since this was a blind study, researcher 2 only participated in the second phase of the research, exporting the digital models in a software to analyze and classify the palatal wrinkles. Researcher 2 performed the total survey of wrinkles per individual and correlated the models from group A with those from group B, obtaining a result of 100% correct. The wrinkle pattern analysis is reliable, precise, and advantageous, but standardizing the classification would facilitate its reproducibility. Given the increased use of technology in dentistry, it is suggested that the digital method be the first choice line for the identification process

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.

Influence of an Intensive Speech Therapy Program on the Speech of Individuals with Cleft Lip and Palate

Abstract Introduction Compensatory articulations are speech disorders due to the attempt of the individual with cleft palate/velopharyngeal dysfunction to generate intraoral pressure to produce high-pressure consonants. Speech therapy is the indicated intervention for their correction, and an intensive speech therapy meets the facilitating conditions for the correction of glottal stop articulation, which is the most common compensatory articulation. Objective To investigate the influence of an intensive speech therapy program (ISTP) to correct glottal stop articulation in the speech of individuals with cleft palate. Methods Speech recordings of 37 operated cleft palate participants of both genders (mean age = 19 years old) were rated by 3 experienced speech/language pathologists. Their task was to rate the presence and absence of glottal stops in the 6 Brazilian Portuguese occlusive consonants (p, b, t, d, k, g) distributed within several places in 6 sentences. Results Out of the 325 pretherapy target consonants rated with glottal stop, 197 (61%) remained with this error, and 128 (39%) no longer presented it. The comparison of the pre- and posttherapy results showed: a) a statical significance for the p1, p2, p3, p4, t1, k1, k2 and d6 consonants (McNemar test; p < 0.05); b) a statistical significance for the p consonant in relation to the k, b, d, g consonants and for the t consonant in relation to the b, d, and g consonants (chi-squared test; p < 0.05) in the comparison of the proportion improvement among the 6 occlusive consonants. Conclusion The ISTP influenced the correction of glottal stops in the speech of individuals with cleft palate.

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.

NECROTIZING SIALOMETAPLASIA OF PALATE A RARE CASE REPORT

Necrotizing sialometaplasia (NS) is a rare benign reactive necrotizing in?ammatory process that affects the minor salivary gland and frequently mimics cancer on both a clinical and histopathological level. Case Study : We report the case of a 21-year-old healthy man who had throat pain and non-healing ulcer over soft palate for the past one month, with pain during swallowing.Histopathological analysis and an incisional biopsy were performed on the patient. Necrotizing sialometaplasia was the histologically determined diagnosis. Necrotizing sialometaplasia is a self-limiting disorder of salivary glands mostly affecting the hard palate.The duration of the healing process is usually related to the size of the lesion.The recurrence rate of Necrotizing Sialometaplasia is low.Even a full thickness palatal lesion heals completely within 6 months.

Preliminary experimental study on the prevention of all-trans retinoic acid induced cleft palate in mice by nicotinamide / 口腔疾病防治

Objective@# To explore the preventive effect of nicotinamide (NAM) on cleft palate induced by all-trans retinoic acid (RA), to provide research evidence for the prevention of cleft palate. @*Methods @#The mouse cleft palate model was induced by intragastric administration of 70 mg/kg all-trans retinoic acid at embryonic day 10.5 (E10.5) in the control group. The mouse cleft palate model was treated by caudal vein injection of 20 mg/kg NAM at E8.5 to E13.5 in the experimental group (1). The cleft palate model was treated by caudal vein injection of 40 mg/kg NAM at E8.5-E13.5 in the experimental group (2). The cleft palate of fetal rats was observed by laparotomy on E16.5 and statistically analyzed. Annexin V-FITC/PI double staining was used to detect the apoptosis of mouse embryonic palatal mesenchyme (MEPM) cells treated with RA 1 μmol/L (RA 1 group), NAM 200 μmol/L (NAM 200 group), and both NAM 200 μmol/L and RA 1 μmol/L (NAM 200+RA 1 group) for 24 hours by flow cytometry and the apoptosis rate in groups were compared. Culture without RA or NAM was used as a control. @*Results @# The cleft palate rate in the control group was 98%. The cleft palate rate in experimental group (1) was 87%. There was no significant difference between groups (P>0.05). The cleft palate rate in the experimental group (2) was 63%, compared with the control group, there was a significant difference (P<0.01). The cell apoptosis rate was 16.53%±2.89% in the CONTROL group. The cell apoptosis rate was 22.9%±1.85% in the RA 1 group, which was a significant increase compared with the CONTROL group (P<0.01). The apoptotic rate of the NAM 200 group was 9.23%±1.39%, which was a significant decrease compared with NA 1 group (P<0.01). The apoptosis rate of the NAM 200+RA 1 group was 14.9%±7.67%, which was a significant decrease compared with the RA 1 group (P<0.01).@*Conclusion@#NAM can prevent cleft palate. 40 mg/kg nicotinamide during pregnancy is an effective concentration for the prevention of RA-induced cleft palate. The mechanism by which NAM prevents cleft palate may be that NAM inhibits RA-induced apoptosis of MEPM cells.

Research progress on early speech interventions for children with cleft lip and palate / 口腔疾病防治

@#Children born with cleft lip and palate (CLP) are at high risk of disorders involving early speech production, and these problems can persist into later childhood, leading to the emergence of compensatory articulation errors. These difficulties in early vocalization directly impact the subsequent development of children's speech and vocabulary. Studies have shown that providing naturalistic interventions, such as milieu teaching and focused stimulation, for children with CLP in the first three years of life have positive impacts on the speech development of children, such as the potential to increase phonemic inventories and the percentage of correct consonants. In addition to speech and language therapists who perform systematic speech therapy, parents can be trained and supervised to deliver early speech intervention. The percentage of correct consonants can be used to assess outcome measures of speech intervention when combined with other measures, such as consonant inventory and speech intelligibility. However, much recent research in the field has focused on older children. Therefore, it must be determined if intervening during the early phase of typical speech development leads to better results. Future research should use more robust methodological designs to determine whether early speech intervention exhibits a positive impact on the speech and future physical and mental development of children with CLP.

3D finite element analysis of the influence of upper lip pressure on the maxilla for patients with unilateral alveolar cleft / 口腔疾病防治

Objective @#To investigate the biomechanical effects of upper lip pressure on the maxilla in patients with a unilateral alveolar cleft and provide evidence for clinical diagnosis and treatment. @*Methods @#A 3D finite element maxillary model was generated based on cone beam CT (CBCT) data from an 11-year-old female patient with a unilateral alveolar cleft. Two different kinds of upper lip pressure, postsurgery pressure and normal pressure, were applied to the model. The displacement and stress of each reference node were compared and analyzed. @*Results @# By loading upper lip pressure, the maxillary alveolar crest rotated toward the defect and was displaced downward and backward. The displacement of the noncleft side was greater than that of the cleft side and it decreased gradually from the anterior to the posterior. The stress was concentrated on the anterior portion of the alveolar crest. The stress on the noncleft side was greater than that on the cleft side and it decreased gradually from the anterior to the posterior. The maximum stress was concentrated on the palate around the defect. The displacement and stress in the postsurgery group were greater than those of the normal group (P<0.05). @*Conclusion @#By loading upper lip pressure, the maxilla demonstrated asymmetry three-dimensionally. The adverse effects on the maxilla could be mitigated by reducing the upper lip pressure.

Clinical application of β-tricalcium phosphate artificial bone material for alveolar cleft repair / 口腔疾病防治

Objective@# To investigate the osteogenic effect of β-tricalcium phosphate (β-TCP) and bone morphogenetic protein-2 (BMP-2) in the repair of the alveolar cleft.@*Methods @# Fifty-nine patients with unilateral alveolar cleft who visited Capital Medical University School of Stomatology from January 2016 to May 2021 were included. They were divided into three groups according to the different bone repair materials: autologous bone, β-TCP and BMP-2 +β-TCP. The preoperative and postoperative CBCT data of the patients were imported into Mimics 21.0 software. The preoperative volume of the bone defect and the new volume of bone formation were calculated by the three-dimensional reconstruction method. The osteogenesis rate was calculated to evaluate the osteogenesis effect@*Results@#The wounds in the three groups healed well after the operation, without implant material discharge, infection, dehiscence, rejection or other symptoms. Twelve months after the operation, CBCT scanning and three⁃dimensional reconstruction images of the three groups of patients showed the formation of new bone bridges in the alveolar ridge fissure area. The image density of the new bone tissue was not significantly different from that of normal bone tissue, and the continuity of the maxilla was re⁃ stored to varying degrees. The bone rate of autogenous bone was 65.00% ± 16.66%, β⁃ TCP group and BMP⁃2+ β⁃ The bone composition rate of TCP was 69.82% ± 17.60%, 71.35% ± 17.51%, respectively, and there was no significant dif⁃ ference compared with the autogenous bone group (P = 0.382, P = 0.244). The β⁃TCP and BMP⁃2+ β⁃TCP groups had no significant differences in bone rate (P = 0.789). @*Conclusion@#β⁃TCP could be used to replace autologous bone for alveolar cleft repair. The addition of BMP⁃2 to β⁃TCP did not significantly improve the osteogenesis rate.

Congenital alveolar synechiae with cleft palate: A case report / 口腔医学

@#An oral synechia is a fibrous or soft tissue adhesion between the maxilla and the mandible. These synechiae can appear at various locations in the oral cavity, with alveolar synechia being one of the manifestations. Alveolar synechia is a rare congenital deformity and often accompanied by additional congenital defects, such as cleft lip or palate, microglossia, micrognathia, or TMJ anomalies. Among these, cleft palate is the most common. A case of congenital alveolar synechiae with cleft palate is reported. The child is in good condition after surgical treatment. The etiology and treatment are discussed.
