Treacher Collins também chamada de disostose mandibulofacial, é uma alteração genética dominante rara caracterizada pela má-formação dos ossos e tecidos da face. É uma síndrome crânio-facial que apresenta alterações bilaterais e simétricas de estruturas originadas do primeiro e segundo arcos branquiais. A maioria dos casos possui transmissão autossômica dominante e expressividade variável. O objetivo do presente estudo é realizar um relato de caso sobre o impacto do tratamento odontológico na qualidade de vida do paciente portador de Treacher Collins. Paciente, 39 anos, sexo feminino compareceu a uma clínica odontológica em Belo Horizonte, com a queixa principal de falhas dentárias e sensibilidade. Durante a anamnese a paciente relatou ter a STC, durante o exame clínico extraoral verificou a presença de hipoplasia malar e mandibular, malformação dos pavilhões auriculares com perda auditiva, obliquidade e coloboma palpebral inferior. Ao exame intraoral observou ser classe II de Angle, ausência dos dentes 11, 12, 13, 21 e 22 e extrusão do dente 41 e recessão gengival e periodontite estágio I grau A. Após exames de periodontograma e complementares foi realizado uma raspagem nas áreas com profundidade de sondagem maior que 3mm, frenectomia labial inferior, aplicação de laser para sensibilidade, enxerto gengival e colocação de prótese parcial removível. A paciente ao final do tratamento relatou ter se sentido realizada e contente com a sua conclusão, ela foi encaminhada ao Sistema único de Saúde para realizar as cirurgias para corrigir as alterações crânio-faciais. O tratamento odontológico deve ser adaptado a cada indivíduo de acordo com sua necessidade, tendo uma abordagem multidisciplinar, possibilitando uma melhora na qualidade de vida e estética do paciente(AU)
Treacher Collins syndrome is a rare dominant genetic disorder characterized by malformation of the bones and tissues of the face. It is a craniofacial syndrome that presents bilateral and symmetrical alterations of structures originating from the first and second branchial arches. The aim of the present study is to perform a case report on the impact of dental treatment on the quality of life of a patient with CTS. Patient, 39 years old, female, attended a dental clinic in Belo Horizonte, with the main complaint of dental flaws and sensitivity. During the anamnesis the patient reported having CTS, during the extraoral clinical examination she verified the presence of malar and mandibular hypoplasia, malformation of the pinnae with hearing loss, obliquity and lower eyelid coloboma. Intraoral examination revealed Angle class II, missing teeth 11, 12, 13, 21 and 22, extrusion of tooth 41, gingival recession and stage I periodontitis grade A. After periodontogram and complementary exams it was performed a scaling in areas with a probing depth greater than 3mm, lower lip frenectomy, laser application for sensitivity, gingival graft and placement of partial removable prosthesis. The patient at the end of treatment reported feeling fulfilled and happy with its completion, she was referred to the Unique Health System to undergo surgery to correct the craniofacial changes. The current treatment aims at functional and aesthetic correction and the need for psychosocial support, having the joint participation of a multidisciplinary team to achieve this goal(AU)

Los trastornos del desarrollo son aquellos padecimientos que se manifiestan por defectos en la embriogénesis de la región afectada. La cara del ser humano comienza su formación alrededor de la cuarta semana de vida intrauterina y se manifiesta gracias a la fusión de cinco prominencias: dos pares conocidas como maxilar y mandibular, y una impar conocida como frontonasal. Cuando esta fusión no se lleva a cabo de una forma óptima, aparecen numerosas alteraciones del desarrollo como el labio y paladar hendido, y la displasia frontonasal. La displasia frontonasal produce frecuentemente afecciones oculares, nasales y orales. Dentro de las manifestaciones orales destacan una forma atípica de hendidura labial o palatina, afecciones dentales y alteraciones en el crecimiento de la cara. Dada la gran relación que este padecimiento tiene con la cavidad oral resulta importante que el odontólogo conozca la etiología y las características clínicas de este trastorno (AU)
Developmental disorders are those conditions that are manifested by defects in the embryogenesis of the affected region. The human face begins its formation around the fourth week of intrauterine life and is manifested thanks to the fusion of five prominences: two pairs known as maxillary and mandibular and odd one known as frontonasal. When this fusion is not carried out in an optimal way, numerous developmental alterations appear, such as cleft lip and palate and frontonasal dysplasia. Frontonasal dysplasia frequently produces ocular, nasal and oral affections. Among the oral manifestations, and atypical form of clef lip and/or palate, dental affections and alterations in the growth of the face stand out. Given the great relationship that this condition has with the oral cavity, it is important for the dentist to know the etiology and clinical characteristics of this disorder (AU)

A Craniossinostose Coronal bilateral implica em diminuição do Perímetro Craniano (PC) no eixo ântero-posterior (Braquicefalia) e frequentemente se associa ao aumento do eixo céfalo-caudal (vertical-altura) do crânio (Turricefalia), sendo um dos achados mais comuns nas Síndromes de Crouzon e Apert. Objetivo: Identificar, analisar e sintetizar os métodos de avaliação cognitiva apropriados para o acompanhamento da evolução de pacientes com cranioestenoses sindrômicas, em particular as síndromes de Apert e de Crouzon. Método: Trata-se de uma revisão de escopo. Para a formulação da pergunta norteadora da pesquisa e da estratégia de busca, foi utilizada a estratégia Population [((Apert OR Crouzon) AND (Disease OR Syndrom*))], Concept [((cognit* OR neurobehavioral OR neurocognit* OR neuropsyc*) AND (evaluation OR evaluations OR assessment OR "test" OR tests OR status OR development OR disorder OR disorders OR impairment OR impairments OR impaired OR function OR functions))] e Context (em qualquer contexto). Foram inclusos os artigos escritos em inglês, português e espanhol em qualquer período. A busca foi realizada nas bases de dados: Embase, Scopus, PubMed/MEDLINE e rede BVS Salud. Resultados:Inúmeros testes de avaliação cognitiva validados internacionalmente foram aplicados aos pacientes com Apert e Crouzon, mas não se observou uma padronização (protocolo) seguida pelas várias unidades de assistência. Dos 75 tipos de Testes Cognitivos aplicados houve o predomínio da Escala de Inteligência de Wechsler (e seus subtestes), 50%. Na população avaliada predominou duas faixas etárias: escolares e adolescentes. As crianças com Apert e Crouzon obtiveram escores piores nos transtornos de socialização, atenção e internalização quando comparadas com o grupo normativo, sendo os piores resultados encontrados em Apert. Fatores que interferem no desenvolvimento neuropsicomotor: pressão intracraniana, malformações encefálicas, genética, idade na correção cirúrgica (postergação da primeira cirurgia após um ano de idade associou-se a um quociente de inteligência mais baixo), institucionalização, ambiente familiar, escolaridade dos cuidadores e nível socioeconômico. Considerações finais: os resultados obtidos contribuíram para maior conhecimento do perfil cognitivo dos pacientes com estas síndromes. Somente conhecendo as habilidades e dificuldades neuropsicomotoras, cognitivas e psicossociais dos pacientes com Apert e Crouzon é que as equipes de saúde, da escola e de cuidadores poderão entender melhor a capacidade perceptiva destes no processo de aprendizado e estarão mais aptas em atender as necessidades especiais destes pacientes e poderão ofertar os estímulos mais adequados no momento mais oportuno (AU).
Bilateral Coronal Craniosynostosis implies a decrease in the Cranial Perimeter (CP) in the anteroposterior axis (Brachycephaly) and is frequently associated with an increase in the cephalocaudal (vertical height) axis of the skull (Turrycephaly); being one of the most common findings in Crouzon and Apert Syndromes (Syndromic Craniosynostosis). In this Scope Review study, among the Syndromic Craniosynostosis, Apert and Crouzon Syndromes will be of special interest. Objective: This study aimed to identify, analyze, and synthesize the appropriate cognitive assessment methods for monitoring the evolution of patients with syndromic craniosynostosis, in particular Apert's and Crouzon's syndromes. Method: This is a scope review. In order to formulate the research guiding question and the searching strategy, the Population [((Apert OR Crouzon) AND (Disease OR Syndrom*))], Concept [((cognit* OR neurobehavioral OR neurocognit* OR neuropsyc*) AND (evaluation OR evaluations OR assessment OR "test" OR tests OR status OR development OR disorder OR disorders OR impairment OR impairments OR impaired OR function OR functions))] and Context (in any context) strategy was used. The articles written in English, Portuguese, and Spanish in any period were included. The search was performed in the following databases: Embase, Scopus, National Library of Medicine (PubMed/MEDLINE), and in the BVS Salud network (PAHO, WHO, BIREME, LILACS). Results: many internationally validated cognitive assessment tests were applied to patients with Apert and Crouzon, but no standardization (protocol) was followed. Of the 75 types of Cognitive Tests applied, the Wechsler Intelligence Scale predominated, 50%. In the evaluated population, two age groups predominated: school children and adolescents. Children with Apert and Crouzon had worse scores on disorders of socialization, attention, and internalization when compared to the normative group, with the worst results found in Apert. Factors that interfere with cognitive development: intracranial pressure, brain malformations, genetics, age at surgical correction, institutionalization, family environment, caregiver education, and socioeconomic status. Conclusion: the results contributed to a better understanding of the cognitive profile of patients with these syndromes and only by knowing about the neuropsychomotor, cognitive, and psychosocial skills and difficulties of these patients with Apert and Crouzon that health, school, and caregiver teams will be able to understand the perceptive capacity in the learning process of these patients deeply and will be able to offer the most appropriate stimuli at the most opportune time. Keywords: Apert, Crouzon, Neuropsyc, Tests, Development (AU).

ABSTRACT Objective: To characterize patients with syndromic craniosynostosis with respect to their neuropsycholinguistic abilities and to present these findings together with the brain abnormalities. Methods: Eighteen patients with a diagnosis of syndromic craniosynostosis were studied. Eight patients had Apert syndrome and 10 had Crouzon syndrome. They were submitted to phonological evaluation, neuropsychological evaluation and magnetic resonance imaging of the brain. The phonological evaluation was done by behavioral observation of the language, the Peabody test, Token test and a school achievement test. The neuropsychological evaluation included the WISC III and WAIS tests. Results: Abnormalities in language abilities were observed and the school achievement test showed abnormalities in 66.67% of the patients. A normal intelligence quotient was observed in 39.3% of the patients, and congenital abnormalities of the central nervous system were observed in 46.4% of the patients. Conclusion: Abnormalities of language abilities were observed in the majority of patients with syndromic craniosynostosis, and low cognitive performance was also observed.

Craniosynostosis is defined as the premature fusion of one or more of the cranial sutures. It leads not only to secondary distortion of skull shape but to various complications including neurologic, ophthalmic and respiratory dysfunction. Craniosynostosis is very heterogeneous in terms of its causes, presentation, and management. Both environmental factors and genetic factors are associated with development of craniosynostosis. Nonsyndromic craniosynostosis accounts for more than 70% of all cases. Syndromic craniosynostosis with a certain genetic cause is more likely to involve multiple sutures or bilateral coronal sutures. FGFR2, FGFR3, FGFR1, TWIST1 and EFNB1 genes are major causative genes of genetic syndromes associated with craniosynostosis. Although most of syndromic craniosynostosis show autosomal dominant inheritance, approximately half of patients are de novo cases. Apert syndrome, Pfeiffer syndrome, Crouzon syndrome, and Antley-Bixler syndrome are related to mutations in FGFR family (especially in FGFR2), and mutations in FGFRs can be overlapped between different syndromes. Saethre-Chotzen syndrome, Muenke syndrome, and craniofrontonasal syndrome are representative disorders showing isolated coronal suture involvement. Compared to the other types of craniosynostosis, single gene mutations can be more frequently detected, in one-third of coronal synostosis patients. Molecular diagnosis can be helpful to provide adequate genetic counseling and guidance for patients with syndromic craniosynostosis.

Son muchos los síndromes que manifiestan alteraciones dento-esqueletales y, a su vez, manifiestan diferentes complicaciones, no permitiendo tener un protocolo definido para cada síndrome. Para establecer un adecuado protocolo de tratamiento, basado en tratamientos realizados exitosamente y tomando en cuenta los fracasos para no incurrir en el mismo error, se hizo una revisión bibliográfica desdemayo hasta septiembre de 2012, de artículos publicados en los últimos diez (10) años, de revistas internacionales de ortodoncia, ortopedia y cirugía maxilofacial que registraban estudios de investigación y casuística, en buscadores científicos como PubMed, Scielo, Medline. Posteriormente, se tomó la clasificación de Kenneth Lyons Jones, MD, en su obra literaria Patrones Reconocibles de Malformaciones Humanas (2007), tomando en cuenta para la elaboración de este trabajo, los que presentan craneosinostosis, defectos faciales mayores y defectos faciales y de las extremidades como características mayores, que ameritan tratamiento para corregir problemas dento-esqueletales. De los 39 artículos se seleccionaron 11 que tenían relevancia con su tema. Conocer y describir todos los síndromes, mencionando cada característica, es de suma importancia para los profesionales de la salud, ya que de ellos depende no sólo el correcto diagnóstico, sino el tratamiento más adecuado...

Genetic disorders occur by excess or absence of chromosomal material, and the consequence of these changes is reflected in morphological and physiological changes. Autosomal disorders, which have dominant inheritance, as cleidocranial dysostosis, Craniofacial syndrome Apert, Treacher Collins and Achondroplasia have peculiar and similar characteristics. Because of their implications in the dental field, the aim of this review is to report on dysostoses, through exposure of general clinical factors and highlighting the signs in the oral cavity. Articles were selected from Lilacs, PubMed and Bireme databases, included in the year 20072014, and the keywords were: cleidocranial dysplasia, craniofacial dysostosis, mandibulofacial dysostosis, dysostosis and oral. Alterations of maxillofacial bones and craniofacial are well documented in the literature, but studies reporting an association between treatment odontologic and dysostoses are scarce. In conclusion, Oral pathological manifestations developed cause difficulty in speech, chewing, breathing, social involvement, and in a general perspective, psychological impairment and physical limitations.
Las enfermedades genéticas se producen debido a un exceso o ausencia de material cromosómico, y la consecuencia de estos cambios se refleja en los cambios morfológicos y fisiológicos. Trastornos autosómicos dominantes que tienen herencia dominante, como la disostosis cleidocraneal, el síndrome craneofacial de Apert, Treacher Collins y acondroplasia tiene características peculiares y similares. Debido a sus implicaciones en el campo de la odontología, el objetivo de esta revisión es hablar, a través de la exposición de los factores clínicos y generales, destacando los signos en la cavidad oral. Se seleccionaron los artículos de las bases de datos Lilacs, PubMed y BIREME, incluyendo los años 2007-2014, y las palabras clave fueron: displasia cleidocraneal, craneofacial mandibulofacial disostosis, disostosis y oral. Los cambios de huesos maxilofaciales y craneofaciales están bien documentados en la literatura, pero los estudios que informaron una asociación entre el tratamiento dental y disostosis son escasos. En conclusion, las manifestaciones orales son causas de dificultades del habla, masticación, respiración y la participación social.

La Microsomía Hemifacial es una altera - ción congénita que comúnmente se presenta en los tejidos blandos y duros de una mitad de la cara con características específicas que definen su diagnóstico haciendo clara su diferencia con otras patologías similares. El objetivo de esta revisión es reconocer en la clínica las características de la microsomía hemifacial para llevar a cabo un correcto diagnóstico. Se realizó una búsqueda en las bases de datos (Scielo, Medline, Science Direct) con las palabras claves: Microsomía Hemifacial, tejidos Blandos, tejidos Óseos). Se obtuvo de la búsqueda de la literatura 64 artículos, con la que se pretendió encontrar información que evaluara los diagnósticos diferencia - les de microsomía hemifacial en tejidos blandos y tejidos duros. El profesional clínico debe reconocer la asociación con síndromes para el tratamiento de la MHF, de esa forma el proceso terapéutico puede cambiar, y debe establecer la severidad de la patología en sus diferentes tejidos para su futura recuperación y establecimiento del plan de tratamiento. El buen diagnóstico y la caracterización de la misma darán un adecuado plan de tratamiento.
The Hemifacial Microsomía is a congeni - tal disorder that commonly occurs in the hard and soft tissues of half of the face with specific characteristics that define its diagnosis, making clear its difference from other similar diseases. The aim of this review is to recognize the clinical features of Hemifacial Microsomía to perform a correct diagnosis. A search was conducted in the databases (Scielo, Medline, Science Direct) with keywords: Hemifacial Micro- somía, Soft tissue, Bone tissue). Sixty four papers assesed the differential diagnosis of HFM. The clinician must recognize the as- sociation with syndromes to treat the HFM, thus the therapeutic process can change, and establish the severity of the disease in different tissues for future retrieval and treatment plan.

Es una displasia ósea no letal caracterizada por cierre prematuro de las suturas coronales, hipoplasia de la parte media de la cara y proptosis ocular. Son los defectos congénitos del cráneo más frecuentes en humanos. El síndrome de Crouzon tiene una prevalencia de 15 en 1 x 106 nacimientos. Existen varias teorías que intentan explicar su patogenia. Hipótesis más actuales sugieren que el defecto se produce por una mutación del gen que codifica el receptor del factor del crecimiento fibroblástico tipo 2 (FGFR2). Los hallazgos ecográficos incluyen braquicefalia, oxicefalia, hipertelorismo e hipoplasia de la zona media de la cara. La sensibilidad del ultrasonido para detectar anomalías craneofaciales depende mucho del operador. La ecografía 3D no incrementa la tasa de detección de la 2D. Recientes estudios radiográficos revelaron frecuentes malformaciones intrauterinas no diagnosticadas. El diagnóstico prenatal se puede realizar por técnicas moleculares. La evolución posnatal es variable.

PURPOSE: The prevalence of antibiotic-resistant Streptococcus pneumoniae meningitis has increased worldwide. There are some reports about postoperative antibiotic-resistant Streptococcus pneumoniae infection after craniofacial surgery, but, there is no report in Korea. We present a report on the treatment of postoperative multidrug-resistant Streptococcus pneumoniae (MRSP) meningitis and sepsis after craniofacial surgery based on our experience. METHODS: The patient was a 7-year-old boy with Crouzon's disease who was treated by fronto-orbital bar advancement. Intraoperatively, frontal sinus opening was seen during osteotomy which was covered with forehead galeopericranial flap. MRSP meningitis was diagnosed after the surgery, he was treated with intravenous vancomycin, meropenem, and levofloxacin. RESULTS: The patient was treated successfully after 3 weeks of intravenous antibiotics treatement. During the 8 month follow-up period, there was no neurologic sequelae. CONCLUSION: Postoperative infection after craniofacial surgery is an important phenomenon that needs immediate recognition. Prevention, early diagnosis, and treatment immediate after onset are important as countermeasures against postoperative drug-resistant bacterial infection. To prevent adverse outcome and reoperation, proper antibiotics treatment should be performed.

<p><b>OBJECTIVE</b>To discuss the segmental monobloc osteotomy and bi-directional distraction for the treatment of Crouzon syndrome in an infant.</p><p><b>METHODS</b>A 9-month-old female infant underwent monobloc osteotomy through combined intra- and extra-cranial way. The facial skull was divided into frontal, orbital and maxillary segments. The external distractor was used to move the frontal segment, orbital segment and midface forward. The internal distractor was used to move the maxilla downward. The consolidation lasted for 3 months after distraction.</p><p><b>RESULTS</b>The osteotomy and distraction were successfully completed. The distraction distance reached 18 mm, showing by distractor. The real distraction distance of facial bone was 12 mm, documented by 3-D image. The skull deformity and severe depression of midface improved a lot. The exophthalmos and underbite were corrected. The obstructive sleep apnea also improved markedly. However, the downward movement of maxilla was limited.</p><p><b>CONCLUSIONS</b>Monobloc osteotomy with external distractor, as well as maxillary distraction, could be used for Crouzon syndrome in infant. It is safe and effective method which can be performed in an early age for Crouzon syndrome with obstructive sleep apnea.</p>
