Effectiveness of iliac cancellous bone grafting in alveolar cleft repair and analysis of factors affecting it / 华西口腔医学杂志

OBJECTIVES@#To review the effectiveness of secondary alveolar bone grafting using iliac cancellous bone in patients with unilateral complete alveolar cleft and to investigate the factors influencing it.@*METHODS@#A retrospective study of 160 patients with unilateral complete alveolar clefts who underwent iliac cancellous bone graft repair at the Department of Cleft Lip and Palate Surgery, West China Hospital of Stomatology, Sichuan University, was conducted. Eighty patients in the young age group (6-12 years) and 80 in the old age group (≥13 years) were included. Bone bridge formation was determined using Mimics software, and the volume was measured to calculate the iliac implantation rate, residual bone filling rate, and resorption rate. The factors that affected bone grafting in both subgroups were investigated.@*RESULTS@#Using bone bridge formation as the clinical success criterion, the success rate for the entire population was 71.25%, with a significant difference of 78.75% and 63.75% for the young and old age groups, respectively (P=0.036). The gap volume in the latter was significantly larger than that in the former (P<0.001). The factors that influenced bone grafting in the young group were the palatal bone wall (P=0.006) and history of cleft palate surgery (P=0.012), but only the palatal bone wall affected the outcome in the old age group (P=0.036).@*CONCLUSIONS@#The results of alveolar bone grafting for the old age group were worse than those for the young age group. The palatal bone wall was an important factor that affected alveolar bone grafting, and alveolar bone grafting in the young patients was influenced by the history of cleft palate surgery.

Two-stage alveolar bone grafting for nasal floor reconstruction in adult cleft patients / 华西口腔医学杂志

Alveolar cleft is one of the key links of cleft lip and palate reconstruction due to its close relationship with tooth and jaw coordination and nasolabial deformity. The alveolar bone graft repairs the hole in the gum ridge and stabilizes the bone arch, providing better support for the base of the nose and new bone for the roots of the developing teeth to grow into. Unfortunately, bone graft failure in the traditional way, even among minor clefts, bony hypoplasia, or absence that affects the nasal base and piriform rim, is common. Two-stage alveolar bone grafting, which has advantages in addressing the underlying skeleton and deficiency, could be an optional surgical procedure for nasal floor reconstruction in adult patients with a broad alveolar cleft.

Modificación de Mulliken en la reparación de la fisura labial unilateral incompleta en Matanzas, 2016-2018 / Mulliken modification in the repair of incomplete unilateral cleft lip in Matanzas, 2016-2018

RESUMEN El impacto biológico, social, económico y psicológico que acarrea la fisura labial conlleva a aplicar nuevas modificaciones en la corrección quirúrgica de sus técnicas de tratamiento. El objetivo de esta investigación fue evaluar los resultados de la técnica quirúrgica de Rotación y Avance de Millard modificada por Mulliken en la corrección de la fisura labial unilateral incompleta en Matanzas. Se realizó un estudio de casos, longitudinal, prospectivo en el Hospital Docente Pediátrico «Eliseo Noel Caamaño¼ de Matanzas, entre 2016 y 2018. El universo estuvo constituido por menores de un año diagnosticados de fisura labial unilateral incompleta, que asistieron a la consulta de Cirugía Maxilofacial de dicho hospital, en el período en que se realizó la investigación y en los que para su tratamiento se empleó la técnica de Rotación y Avance de Millard modificada por Mulliken. Se trabajó con la totalidad del universo. Se utilizó estadística descriptiva. Los pacientes fueron intervenidos entre los 5 y 9 meses, predominó el color de piel blanca (75 %) y el sexo masculino (75 %). La altura labial y el ancho heminasal aumentaron más en el lado sano que en el fisurado. Al año de la intervención en el lado fisurado creció más el ancho transversal que en el sano en dos de los casos y también existió una diferencia mayor de 1 mm en la altura del bermellón. Se logró alcanzar simetría nasolabial en espejo del lado sano en todas las variables, excepto en la altura del bermellón en dos casos.

ABSTRACT The biological, social, economic and psychological impact caused by cleft lip leads to the application of new modifications in the surgical correction of its treatment techniques. The objective of this research was to evaluate the results of the Millard's rotation-advancement surgical technique modified by Mulliken in the correction of incomplete unilateral cleft lip in Matanzas. A longitudinal, prospective study was conducted at "Eliseo Noel Caamaño" Pediatric Teaching Hospital, in Matanzas between 2016 and 2018. The universe was made up of children under one year of age diagnosed with incomplete unilateral cleft lip, who come to the Maxillofacial Surgery consultation of this hospital, in the period in which the investigation was carried out and in whom, Millard 's rotation-advancement surgical technique modified by Mulliken was used for their treatment. We worked with the entire universe. Descriptive statistics was used. The patients underwent surgery between 5 and 9 months, white skin color (75%) and male gender (75%) predominated. Labial height and heminasal width increased more on the healthy side than on the cleft side. One year after the intervention, the transverse width grew more on the cleft side than on the healthy side in two of the cases, and there was also a difference greater than 1 mm in the vermilion height. Mirror-image nasolabial symmetry was achieved on the healthy side in all variables, except for vermilion height in two cases.

Qualitative Assessment of Surgical Repair of Three Types of Unilateral Cleft Lip

Abstract Objective: To assess the effect of the three types of unilateral cleft lip (UCL) [cleft lip only, cleft lip and alveolus, and cleft lip alveolus and palate] on the outcome of the repair. Material and Methods: This study was a case series of effect of types of UCL on the outcome of the repair. Fifteen subjects each were in three UCL phenotypes groups. Evaluation of the scar, lip, and nose was done qualitatively by both parents/guardians and professionals using a modified form of the criteria described by Christofides et al. (2006). Results: In the assessment of the surgical scar, the parents found a difference between the three types of cleft in terms of texture, shape, and width of the scar and presence of columella deviation. The professional assessors, however, only found the three types of cleft to be different in the presence of alar flattening. Conclusion: Differences truly exist in the outcome of surgical repair of the three types of unilateral cleft lip, especially in the aesthetics of the nose and in the width and shape of the residual lip scar. Thus, it is important to consider this in the assessment of UCL repair because putting the subtypes together might have a negative impact on the assessment.

Tratamiento del Fisurado Labio Alvéolo Palatino (FLAP): casos clínicos y tratamiento interdisciplinario / Treatment of the cleft lip and palate (CLP) patient: case reports and interdisciplinary treatment

Objetivo: Describir el plan de tratamiento completo para el manejo de pacientes con fisura labio alvéolo palatina (F.L.A.P.), basado en nuestra experiencia clínica de más de 40 años. Casos clínicos: En nuestro protocolo consideramos fundamental el tratamiento ortopédico, teniendo en cuenta los tiempos de crecimiento y desarrollo del maxilar superior de cada paciente, para luego aplicar las técnicas quirúrgicas en un maxilar armónico, con un éxito más predecible. Se describirá una serie de casos clínicos con seguimiento de pacientes. Conclusión: Con este protocolo que pregonamos desde hace muchos años, nos diferenciamos principalmente de otras propuestas por considerar los tiempos biológicos de cada paciente en cuanto a crecimiento y desarrollo, y no por basarnos en tiempos quirúrgicos preestablecidos. Aplicando este protocolo obtenemos resultados predecibles que entendemos que solo son posibles de evaluar, al realizar el seguimiento del paciente hasta completar su desarrollo (AU)

Objective: To describe the comprehensive treatment plan aimed at managing patients with cleft lip and palate (CLP) on the basis of our more than forty years of clinical experience. Case reports: e orthopedic treatment is deemed fundamental in the present protocol, which takes into account the maxilla growth and development periods of each individual patient, to later perform a surgical technique in a harmonized maxilla, with a more predictable success. Clinical cases with the patient follow-up shall be described. Conclusion: e main difference between the present protocol that has been held for many years and others proposed approaches mainly lies in considering the unique growth and developmental biological stages of each patient and not in drawing on pre-established surgical timing. When applying this protocol, predictable results are achieved and they are only meant possible to be assessed during the thorough patient follow-up (AU)

Innovative method to assess maxillary arch morphology in oral cleft: 3d-3d superimposition technique

Abstract This study aimed to analyze the maxillary growth and development of children with oral clefts using the innovative method of 3D-3D superimposition technique. Children with unilateral complete cleft lip (UCL) and unilateral cleft lip and palate (UCLP) participated in the study. The impressions of the dental arches were executed 1 day before and 1 year after lip repair surgery. A 3D laser scanner digitized the dental models and the stereophotogrammetry system software analyzed the 3D-3D superimpositions in two groups of matches (same child, UCL and UCLP) and one group of mismatches (different individuals). The differences were evaluated by Root Mean Square (RMS) and expressed in millimeters (mm). Kruskal-Wallis test followed by post-hoc Dunn test and Mann-Whitney test were assessed to compare the groups (α=5%). RMS was 1.34 mm (± 0.37) in UCL group, 1.41 mm (± 0.32) in UCLP group, and 3.38 mm (± 1.28) in mismatches group. RMS was significantly greater in mismatches than in matches groups (p<0.0001). No statistically significant differences occurred between genders. The 3D-3D superimposition technique showed the maxillary development after lip repair surgery in the anterior region of the palate. Thus, it is suggested that the cleft amplitude and the palatal segments proportion influenced the morphological heterogeneity and, consequently, the development and maxillary growth of children with orofacial cleft.

Resumo O objetivo deste estudo foi analisar o crescimento e desenvolvimento maxilar de crianças com fissuras orais por meio de um método inovador da técnica de sobreposição 3D-3D. Participaram do estudo crianças com fissura unilateral completa de lábio (FL) e fissura unilateral de lábio e palato (FLP). As moldagens dos arcos dentários foram realizadas 1 dia antes e 1 ano após o reparo cirúrgico labial. Um scanner a laser 3D digitalizou os modelos dentários e o software do sistema de estereofotogrametria analisou as sobreposições 3D-3D em dois grupos correspondentes (mesmo indivíduo, FL e FLP) e um grupo não-correspondente (indivíduos diferentes). As diferenças foram avaliadas pelo Root Mean Square (RMS) e expressas em milímetros (mm). O teste de Kruskal-Wallis seguido do teste post-hoc de Dunn e teste de MannWhitney foram avaliados para comparar os grupos (α=5%). RMS foi de 1.34 mm (± 0.37) no grupo FL, 1.41 mm (± 0.32) no grupo FLP e 3.38 mm (± 1.28) no grupo não-correspondente. RMS foi significativamente maior no grupo não-correspondente (p <0.0001). Não houve diferenças estatisticamente significativas entre os gêneros. A técnica de sobreposição 3D-3D evidenciou o desenvolvimento da maxila após a cirurgia labial na região anterior do palato. Assim, sugere-se que a amplitude da fenda e a proporção dos segmentos palatinos influenciam na heterogeneidade morfológica e, consequentemente, no desenvolvimento e crescimento maxilar de crianças com fissura orofacial

Association between speech and dental occlusion changes in children with cleft lip and palate and time of primary plastic surgeries / Associação entre alterações de fala e dento-oclusais em crianças com fissura labiopalatina e a época das cirurgias plásticas primárias

ABSTRACT Purpose: to describe the changes in speech and dental occlusion in children with cleft lip and palate and verify their association with each other and with the time of primary plastic surgeries. Methods: a cross-sectional study with collected data on the subjects' identification, age at the time of primary surgeries, and clinical assessment of speech and dental occlusion. The chi-square test, Fisher's exact test, and t-test were used to verify the associations between the variables at the 5% significance level (p < 0.05). Results: the sample comprised 11 children aged 6 to 10 years, most of whom were males, self-reported white, with trans-incisive foramen cleft, predominantly on the left side. The mean age at lip repair surgery was 6 months, and 13 months at palatoplasty. Among the main dental occlusion changes, posterior and anterior crossbite stood out. All the subjects presented changed speech, with a prevalence of cases with dentoalveolar and palatine deformities, followed by passive and active changes. Subjects with anterior crossbite tended to have undergone primary lip repair surgery at a mean of four months earlier than the subjects without anterior crossbite. Conclusions: the associations between speech and dental occlusion changes, and between these and the time of primary plastic surgeries were not statistically significant. Even though it is known that early lip repair surgery is ideal to favor oral functions and aesthetics, the results revealed a tendency towards anterior crossbite, in these subjects.

RESUMO Objetivos: descrever alterações de fala e dento-oclusais em crianças com fissuras labiopalatinas, verificar a associação entre si e destas com a época das cirurgias plásticas primárias. Métodos: estudo transversal, com coleta de dados de identificação, idade nas cirurgias primárias, avaliação clínica dento-oclusal e da fala. Utilizou-se o teste Qui-quadrado, teste exato de Fisher e teste t para verificar as associações entre as variáveis, com um nível de significância de 5% (p < 0,05). Resultados: amostra composta por 11 crianças entre seis e dez anos, sendo a maioria do sexo masculino, etnia autodeclarada branca e fissura transforame incisivo (com prevalência de acometimento do lado esquerdo). A média da realização da labioplastia foi aos seis meses e palatoplastia aos treze meses. Dentre as principais alterações dento-oclusais, destacam-se: mordida cruzada posterior e mordida cruzada anterior. Todos os sujeitos apresentaram alteração de fala com prevalência de alterações em casos com deformidades dentoalveolares e palatinas, seguidas pelas alterações passivas e alterações ativas. Houve tendência dos sujeitos que apresentaram mordida cruzada anterior terem sido submetidos à labioplastia primária, em média, quatro meses antes dos sujeitos sem mordida cruzada anterior. Conclusões: as associações entre alterações de fala e dento-oclusais e destas com a época das cirurgias plásticas primárias não foram estatisticamente significantes, e ainda que se saiba que a labioplastia precoce é o ideal para favorecer funções orais e estética, os resultados demonstraram tendência a mordida cruzada anterior nestes sujeitos.

Avanço cirúrgico de maxila e ressonância de fala: comparação entre os tipos de fissura / Surgical maxillary advancement and speech resonance: comparison among cleft types

RESUMO Objetivo Investigar a influência do tipo de fissura sobre o aparecimento da hipernasalidade após o avanço cirúrgico da maxila (AM). Método A nasalidade foi determinada por meio da medida de nasalância (correlato acústico da nasalidade) utilizando-se a nasometria. Foi realizada a análise dos escores de nasalância de 17 indivíduos com fissura isolada de palato (FP), 118 com fissura de lábio e palato unilateral (FLPU) e 69 com fissura de lábio e palato bilateral (FLPB), de ambos os sexos, com idades entre 18 e 28 anos, submetidos ao AM. Apenas indivíduos com escores de nasalância indicativos de ressonância equilibrada previamente ao AM foram incluídos neste estudo. A nasometria foi realizada, em média, três dias antes e 15 meses após o AM. A proporção de pacientes que apresentaram escores de nasalância indicativos de hipernasalidade após o AM foi calculada por meio do teste ANOVA e a comparação entre os diferentes tipos de fissura foi realizada utilizando-se o teste Qui-quadrado (p < 0,05). Resultados Não foi observada diferença significante entre as proporções de indivíduos com hipernasalidade, de acordo com o tipo de fissura. Conclusão A nasometria mostrou que o aparecimento da hipernasalidade após o AM, em indivíduos com fissura de palato envolvendo ou não o lábio, ocorreu em proporções similares independentemente do tipo de fissura.

ABSTRACT Purpose This study investigated the influence of the cleft type on the appearance of hypernasality after surgical maxillary advancement (MA). Methods Nasality was determined by measurement of nasalance (acoustic correlate of nasality) by nasometry. The study involved analysis of the nasalance scores of 17 individuals with isolated cleft palate (CP), 118 with unilateral cleft lip and palate (UCLP) and 69 with bilateral cleft lip and palate (BCLP), of both sexes, aged 18 to 28 years, after MA. Only individuals with normal nasalance scores indicating balanced resonance before MA were included in this study. Nasometry was performed 3 days before and 15 months after MA, on average. The proportion of patients who presented nasalance scores indicating hypernasality after surgery was calculated by the ANOVA test, and comparison among the different cleft types was evaluated by the chi-square test (p < 0.05). Results No significant difference was found in the proportions of individuals with hypernasality among the cleft types. Conclusion Nasometry showed that the appearance of hypernasality after MA in individuals with cleft palate with or without cleft lip occurred in similar proportions, regardless of the cleft type.

Effect of CO₂ fractional laser on the early control of scar post-secondary repair in patients with a cleft lip / 华西口腔医学杂志

OBJECTIVE@#To observe and compare the clinical efficacy of CO₂ fractional laser in the early control of scar post-secondary repair in patients with a cleft lip.@*METHODS@#In the treatment group, 43 patients with secondary repair of cleft lip were treated via CO₂ fractional laser. The control group covered 70 patients post-cheiloplasty. The effect in the two groups after six months was compared. The duration from the beginning of the laser treatment to surgery and patient gender were analyzed to determine if they affected the efficacy of the laser treatment for scars.@*RESULTS@#1) The curative effect in the treatment group was better than that in the control group (P<0.000 1), the total effectiveness rate was 90.7% in the treatment group. 2) No significant statistical difference in efficacy was observed between men and women (P=0.487). Moreover, no significant statistical difference in efficacy (P=0.055) was observed among patients one year after surgery, within the duration of <3 months, and within the duration of ≥3 months.@*CONCLUSIONS@#CO₂ fractional laser had a definite effect on the treatment of scar post-secondary repair in patients with a cleft lip. No significant correlation was observed between treatment effect and patient gender, and no difference was noted among patients one year after surgery. In the beginning of the laser treatment, no difference was observed between the durations of <3 months and ≥3 months after the reconstruction, Therefore, early intervention of scars a year after secondary repair of a cleft lip can achieve good results.

Finite element analysis of the comprehensive impact of scar and maxillary expansion combined with protraction on the development of maxilla with cleft lip and palate after repair operation / 华西口腔医学杂志

OBJECTIVE@#To study the comprehensive impact of scar and maxillary expansion combined with protraction on the development of maxilla with cleft lip and palate after repair operation.@*METHODS@#In the original finite element model of the maxilla with cleft palate, a finite element model of the maxilla with cleft lip and palate was established by using Boolean operation in ANSYS. Scar force after cleft lip and palate repair and maxillary expansion force combined with protraction were added simultaneously to process the stress analysis.@*RESULTS@#Maxillary deformation occurred in the three-dimensional direction. The comparison of displacements was as follows: X-axis>Z-axis>Y-axis.@*CONCLUSIONS@#Maxillary growth is significantly inhibited in the three-dimensional direction under the comprehensive impact of scar and maxillary expansion combined with protraction after repair operation, especially transverse and sagittal growth.
