A relevância da odontologia na Síndrome Treacher Collins: relato de caso / The relevance of dentistry in Treacher Collins Syndrome: case report

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.

TCOF1 Gene variation in Treacher Collins syndrome and evaluation of speech rehabilitation after bone bridge surgery / 临床耳鼻咽喉头颈外科杂志

Objective:By analyzing the clinical phenotypic characteristics and gene sequences of two patients with Treacher Collins syndrome（TCS）, the biological causes of the disease were determined. Then discuss the therapeutic effect of hearing intervention after bone bridge implantation. Methods:All clinical data of the two family members were collected, and the patients signed the informed consent. The peripheral blood of the proband and family members was extracted, DNA was extracted for whole exome sequencing, and Sanger sequencing was performed on the family members for the mutation site.TCOF1genetic mutations analysis was performed on the paitents. Then, the hearing threshold and speech recognition rate of family 2 proband were evaluated and compared under the sound field between bare ear and wearing bone bridge. Results:In the two pedigrees, the probands of both families presented with auricle deformity, zygomatic and mandibular hypoplasia, micrognathia, hypotropia of the eye fissure, and hypoplasia of the medial eyelashes. The proband of Family 1 also presents with specific features including right-sided narrow anterior nasal aperture and dental hypoplasia, which were consistent with the clinical diagnosis of Treacher Collins syndrome. Genetic testing was conducted on both families, and two heterozygous mutations were identified in the TCOF1 gene: c. 1350_1351dupGG（p. A451Gfs*43） and c. 4362_4366del（p. K1457Efs*12）, resulting in frameshift mutations in the amino acid sequence. Sanger sequencing validation of the TCOF1 gene in the parents of the proband in Family 1 did not detect any mutations. Proband 1 TCOF1 c. 1350_1351dupGG heterozygous variants have not been reported previously. The postoperative monosyllabic speech recognition rate of family 2 proband was 76%, the Categories of Auditory Performance（CAP） score was 6, and the Speech Intelligibility Rating（SIR） score was 4. Assessment using the Meaningful Auditory Integration Scale（MAIS） showed notable improvement in the patient's auditory perception, comprehension, and usage of hearing aids. Evaluation using the Glasgow Children's Benefit Inventory and quality of life assessment revealed significant improvements in the child's self care abilities, daily living and learning, social interactions, and psychological well being, as perceived by the parents. Conclusion:This study has elucidated the biological cause of Treacher Collins syndrome, enriched the spectrum of TCOF1 gene mutations in the Chinese population, and demonstrated that bone bridge implantation can improve the auditory and speech recognition rates in TCS patients.

Treacher Collins Syndrome: A Rare and Special Case Report of a 9-Year-Old Boy from Saudi Arabia

Treacher Collins syndrome (TCS) is characterized by downslanting palpebral fissures on both sides, malar hypoplasia, micrognathia, and external ear abnormalities. Hypoplasia of the zygomatic bones and jaw may make it difficult to eat and breathe. TCS, also known as Franceschetti syndrome or mandibulofacial dysostosis, is an autosomal dominant craniofacial condition with a wide range of symptoms. Edward Treacher Collins (1862?1932), an English ophthalmologist, first defined the syndrome’s fundamental characteristics in 1900. This syndrome is approximately affecting 1 in 50,000 live births with equal gender affection. In Saudi Arabia, it follows a similar pattern of prevalence. Antimongoloid slanting palpebral fissures, colobomas of the lower eyelid, hypoplasia of the zygoma and mandible, auditory microtia, conductive hearing loss, obstructive sleep apnea, and a range of orofacial abnormalities are the most prevalent clinical symptoms of TCS. In this case report, the author describes a deep-rooted analysis of the clinical features of TCS in a 9-year-old boy as well as his follow-up case. The study was conducted for a period of 9 years from birth to 9 year-old age, which makes this case report as a special rare 9-year follow-up case report from Saudi Arabia.

Cuando los recién nacidos presentan obstrucción de la vía aérea, requieren un manejo urgente y experto para evitar la mortalidad y la morbilidad. La definición de vía aérea difícil se relaciona con problemas en la intubación endotraqueal o en la ventilación a presión positiva con bolsa y máscara o reanimador de pieza en T. El manejo debe basarse en la comprensión del mecanismo fisiopatológico responsable de la vía aérea difícil. Las causas en el recién nacido pueden ser congénitas y/o adquiridas.Se presenta el caso de una recién nacida con síndrome de Treacher-Collins tipo 1 [OMIM #154500] con una disostosis mandibulofacial, micrognatia, hipoplasia malar, paladar hendido, sin cardiopatía congénita, asociado con intubación extremadamente difícil

f newborns have an airway obstruction, they require urgent and expert management to avoid mortality and morbidity. The definition of difficult airway includes problems in endotracheal intubation or positive pressure ventilation with bag and mask or T-piece resuscitator. Management should be based on an understanding of the pathophysiological mechanism responsible for difficult airway. The causes of difficult airway in the newborn can be congenital or acquired.We present the case of a newborn with Treacher-Collins syndrome Type 1 [OMIM # 154500] with a mandibulofacial dysostosis, micrognathia, malar hypoplasia, cleft palate, without congenital heart disease, associated with extremely difficult intubation

Anestesia en paciente pediátrico con Síndrome de Treacher Collins / Anesthesia in pediatric patient with Treacher Collins Syndrome

El Síndrome de Treacher Collins (STC) constituye un reto para el anestesiólogo por malformaciones craneofaciales que complican el manejo de su vía aérea e intubación. Presentamos el caso de una paciente (8 años) con diagnóstico de STC que debía someterse a una cirugía de colocación de implante de conducción ósea bajo anestesia general. Presentaba un antecedente de intubación difícil, marcada micrognatia y distancia tiromentoniana de 2 cm. Se planteó un esquema de intubación en dos etapas secuenciales. En la primera etapa se realizó una evaluación de la vía aérea (visualización de la glotis) bajo sedación con dexmedetomidina, remifentanilo y propofol. Al visualizar la glotis se pasó a la segunda etapa para realizar la intubación posterior a la inducción anestésica. El manejo exitoso se fundamentó en una sedación adecuada y la utilización de un videolaringoscopio con pala curva para la evaluación previa de la vía aérea y posterior intubación sin complicaciones.

Treacher Collins Syndrome (TCS) constitutes a challenge for the anesthesiologist due to craniofacial malformations that make management of the airway and intubation difficult. We present a case of a patient (8-year-old) diagnosed with TCS who had to undergo surgery for the placement of a bone conduction implant under general anesthesia. She had a history of difficult intubation, marked micrognathia and a thyromental distance of 2 cm. An intubation scheme in two sequential stages was proposed. In the first stage, an evaluation of the airway (visualization of the glottis) was carried out under sedation with dexmedetomidine, remifentanil and propofol. When the glottis was visualized, we proceeded to the second stage to carry out intubation after anesthetic induction. The successful management of this case was based on adequate sedation and the use of a video laryngoscope with a curved blade for prior evaluation of the airway and subsequent intubation without complications.

Narrativas sobre a vida e o início do tratamento de uma paciente com Síndrome de Treacher Collins: um estudo de caso / Stories about life and treatment onset of a patient with Treacher Collins syndrome: case study

Síndrome de Treacher Collins (STC) é uma anomalia do desenvolvimento craniofacial rara de manifestação clínica variável. Este estudo teve por objetivo principal analisar a experiência de uma mulher de 26 anos com STC que iniciou a reabilitação na idade adulta, buscando aprofundar possíveis impactos para o seu desenvolvimento. Com aprovação do Comitê de Ética em Pesquisa (CAAE 00981418.3.0000.5441), realizou-se um estudo de caso clínico por meio da análise documental do prontuário multiprofissional e uma entrevista semiestruturada gravada em áudio, transcrita integralmente e analisada qualitativamente pela técnica de Análise de Conteúdo de Bardin. Evidenciaram-se duas categorias temáticas que sinalizam a experiência de vida da participante dividida em dois momentos: (1)"Desenvolvimento até a fase adulta" que abarcou as subcategorias: "O que eu tenho?"; "Relacionamento com a mãe"; "Eu sofri bullying: desafio da escolarização" (2) "Ser alguém com Síndrome de Treacher Collins", e subcategorias: "Existem outros como eu: conhecendo o diagnóstico"; "Início do tratamento: desafios e expectativas"; "A psicologia e a equipe interdisciplinar"; "Mas hoje eu sou feliz: planos para o futuro". STC, sendo uma malformação facial, pode implicar em conviver com o estigma de não apresentar o rosto dentro dos padrões sociais impostos. No caso analisado, apontou-se sofrimento emocional, sendo este intensificado pelo não pedido de ajuda. Por outro lado, o diagnóstico da síndrome possibilitou o processo de identificação com outros sujeitos acometidos, o início da reabilitação e a vivência de impactos positivos em sua qualidade de vida. A psicologia figurou como espaço de escuta e possibilidade de reflexão sobre o processo de reabilitação.

The Treacher Collins syndrome (TCS) is a rare anomaly of craniofacial development with variable clinical manifestation. The main goal of this study was to analyze the experience of a 26-year-old woman with TCS who initiated her rehabilitation in adulthood, aiming to deepen the possible impacts on her development. After approval by the Institutional Ethics Review Board (CAAE 00981418.3.0000.5441), the case study was conducted by documental analysis of the multiprofessional patient records and a semi-structured interview recorded in audio, transcribed in full and qualitatively analyzed by the Content Analysis technique of Bardin. Two theme categories were evidenced that indicated the life experience of the participant divided in two periods: (1) "Development up to adulthood", which included the subcategories: "What's wrong with me?"; "Relationship with the mother"; "I suffered bullying: challenge of school education" (2) "Being someone with Treacher Collins syndrome", and subcategories: "There are others like me: knowing the diagnosis"; "Treatment onset: challenges and expectations"; "Psychology and the interdisciplinary team"; "But I am happy today: plans for the future". Since TCS is a facial malformation, it may involve living with the stigma of not presenting a face within the imposed social standards. The present case presented emotional suffering, worsened because she did not ask for help. Conversely, the diagnosis of the syndrome allowed the process of identification with other affected individuals, the onset of rehabilitation and experience of positive impacts on her quality of life. Psychology participated as a space for hearing and possibility of reflecting about the rehabilitation process.

Pathogenic genes and clinical therapeutic strategies for Treacher Collins syndrome / 华西口腔医学杂志

Treacher Collins syndrome is a congenital craniofacial malformation with autosomal dominant inheritance as the main genetic pattern. In this condition, the biosynthesis of ribosomes in neural crest cells and neuroepithelial cells is blocked and the number of neural crest cells that migrate to the craniofacial region decreases, causing first and second branchial arch dysplasia. Definite causative genes include treacle ribosome biogenesis factor 1 (tcof1), RNA polymerase Ⅰ and Ⅲ subunit C (polr1c), and RNA polymerase Ⅰ and Ⅲ subunit D (polr1d). This paper provides a review of research of three major patho-genic genes, pathogenesis, phenotypic research, prevention, and treatment of the syndrome.

Progress of diagnosis and treatment of upper respiratory obstruction in patients with Treacher Collins syndrome / 中国修复重建外科杂志

Objective: To summarize the progress of diagnosis and treatment of upper respiratory obstruction in patients with Treacher Collins syndrome (TCS). Methods: The domestic and abroad literature about the diagnosis and treatment of upper respiratory obstruction in patients with TCS was extensively reviewed and analyzed. Results: TCS is an autosomal-dominant craniofacial developmental syndrome. It is often accompanied by midface and/or mandibular hypoplasia, soft tissue hypertrophy, and other respiratory tissue developmental abnormalities, which can lead to different degrees of upper respiratory obstruction symptoms. Respiratory obstruction in patients with TCS is affected by many factors, and the obstructive degree are different. Early detection of the causes and obstructive sites and adopted targeted treatments can relieve the symptoms of respiratory obstruction and avoid severe complications. Conclusion: Due to the low incidence of TCS, there is still a lack of high-quality research evidence to guide clinical treatment. Large-scale and prospective clinical studies are needed to provide new ideas for the treatment and prevention of upper respiratory obstruction.

Traz a deformidade de orelha impacto negativo na qualidadede vida em indivíduos com síndrome de Treacher Collins? / Does an ear deformity bring an adverse impact on quality of life of Treacher Collins syndrome individuals?

Resumo A Síndrome de Treacher Collins (STC) é uma síndrome craniofacial de padrão autossômico dominante e expressão clínica variada, em que a orelha pode ou não estar ausente ou malformada. Indivíduos com STC sofrem estigmas podendo repercutir na interação com pares. Instrumentos de qualidade de vida obtidos por meio de questionários de autopercepção são ferramentas de identificação de estigmas e podem permitir o ajuste social desses indivíduos. Objetiva-se avaliar e mensurar a qualidade de vida em indivíduos com STC, aferindo os impactos da deformidade de orelhas na qualidade de vida. Doze voluntários com diagnóstico clínico e genético de STC responderam ao questionário de qualidade de vida da OMS, divididos em grupos com orelhas normais (n = 6) versus orelhas afetadas (n = 6) e seus resultados foram comparados. A escala de Siviero foi usada para estratificar a qualidade de vida em satisfatória, intermediária e insatisfatória. A pontuação geral do grupo com orelhas normais foi de 73,13; a do grupo com orelhas afetadas de 71,81, ambos classificados como níveis intermediários de qualidade de vida e sem diferença significativa entre si. A deformidade de orelha não representa um ônus na qualidade de vida dos indivíduos que já se apresentam com outras deformidades e com escores de qualidade de vida intermediários.

Abstract Treacher Collins syndrome (TCS) is an autosomal dominant disorder with variable expression in which the ear may or may not be absent or with a malformation. Individuals with TCS suffer social stigma that may affect interaction with their peers. Quality of life instruments obtained through self-perception questionnaires are stigma identification tools and can enable social adjustment of these individuals. This study aims to assess the quality of life of individuals with TCS and to gauge the impacts of ear deformity on the quality of life. Twelve volunteers with a clinical and genetic diagnosis of TCS answered the WHO quality of life questionnaire and were divided into groups with normal ears (n = 6) versus affected ears (n = 6), and their results were compared. Siviero's scale was used to stratify the quality of life scores as satisfactory, intermediate and unsatisfactory. The overall score of the normal ears group was 73.13 and 71.81 for the affected ears group, and both were classified as an intermediate quality of life, with no statistically significant differences between them. Ear deformity is not a burden to the quality of life of these individuals, who already show other deformities and overall intermediate quality of life scores.

Difficult fiberoptic tracheal intubation in 1 month-old infant with Treacher Collins Syndrome / Intubação traqueal difícil com fibra óptica em bebê de um mês de idade com síndrome de Treacher Collins

Abstract Neonates and small infants with craniofacial malformation may be very difficult or impossible to mask ventilate or intubate. We would like to report the fiberoptic intubation of a small infant with Treacher Collins Syndrome using the technique described by Ellis et al. Case report: An one month-old infant with Treacher Collins Syndrome was scheduled for mandibular surgery under general endotracheal anesthesia. Direct laryngoscopy for oral intubation failed to reveal the glottis. Fiberoptic intubation using nasal approach and using oral approach through a 1.5 size laryngeal mask airway were performed; however, both approach failed because the fiberscope loaded with a one 3.5 mm ID uncuffed tube was stuck inside the nasal cavity or inside the laryngeal mask airway respectively. Therefore, the laryngeal mask airway was keep in place and the fiberoptic intubation technique described by Ellis et al. was planned: the tracheal tube with the 15 mm adapter removed was loaded proximally over the fiberscope; the fiberscope was advanced under video-screen visualization into the trachea; the laryngeal mask airway was removed, leaving the fiberscope in place; the tracheal tube was passed completely through the laryngeal mask airway and advanced down over the fiberscope into the trachea; the fiberscope was removed and the 15 mm adapter was reattached to the tracheal tube. Conclusion: The fiberoptic intubation method through a laryngeal mask airway described by Ellis et al. can be successfully used in small infants with Treacher Collins Syndrome.

Resumo Os recém-nascidos e crianças pequenas com malformação craniofacial podem ser muito difíceis ou impossíveis de ventilar por máscara ou de intubar. Gostaríamos de relatar a intubação com fibra óptica de um bebê com síndrome de Treacher Collins usando a técnica descrita por Ellis et al. Relato de caso: Uma criança de um mês de idade com síndrome de Treacher Collins foi programada para cirurgia mandibular sob anestesia geral endotraqueal. A laringoscopia direta para intubação oral não revelou a glote. A intubação com fibra óptica usando as abordagens nasal e oral por meio de máscara laríngea de tamanho 1,5 foi tentada, mas ambas as abordagens falharam porque o fibroscópio portando um tubo sem balonete de 3,5 mm ficou preso no interior da cavidade nasal ou dentro da máscara laríngea, respectivamente. Portanto, a máscara laríngea foi mantida no lugar e a técnica de intubação com fibra óptica descrito por Ellis et al. foi planejada: o tubo traqueal com o adaptador de 15 mm removido foi colocado proximalmente sobre o fibroscópio; o fibroscópio foi avançado na traquéia sob visualização em tela devídeo; a máscara laríngea foi removida, deixando o fibroscópio no lugar; o tubo traqueal foi passado completamente através da máscara laríngea e avançado para baixo sobre o fibroscópiona traquéia; o fibroscópio foi removido e o adaptador de 15 mm foi recolocado no tubo traqueal. Conclusão: O método de intubação com fibra óptica através de uma máscara laríngea descrito por Ellis et al. pode ser usado com sucesso em bebês com síndrome de Treacher Collins.

Contouring of zygomatic soft tissue using bilateral free groin flaps in a Treacher Collins syndrome patient

Treacher Collins syndrome is a congenital disorder that is characterized with a wide range of cranio-facial deformities. Zygomatic hypoplasia or aplasia is one of the key features, and surgical reconstruction of the consequent depression on the zygomatic area is deemed necessary by many patients. Various surgical options are available—injectables, alloplastic materials, autologous grafting, and autogenous tissue transfer. It depends on each patient which technique to use. Here, we present a clinical case, in which bilateral free groin flaps were adopted in attempt to resolve the remnant aesthetic deformity associated with zygomatic depression, despite a series of previous surgical efforts, in a 25-year-old Treacher Collins syndrome male patient.

Management of obstructive sleep apnea in a Treacher Collins syndrome patient using distraction osteogenesis of the mandible

In this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient’s respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.

Síndrome de Treacher-Collins. Presentación de un caso / Treacher-Collin syndrome. Presentation of a case

El síndrome de Treacher Collins es también conocido como síndrome de Berry-Franceschetti-Klein o Franceschetti-Zwahlen-Klein. Disostosis mandibulofacial o síndrome del primer arco, se corresponde con un desorden autosómico dominante del desarrollo craneofacial, y puede mostrar innumerables manifestaciones clínicas. En el caso presentado se pudieron observar múltiples malformaciones craneofaciales así como una severa escoliosis, atresia del conducto auditivo externo, papilomas preauriculares bilaterales y polidactilia preaxial en la mano derecha.

Treacher-Collin syndrome, also known as Berry-Franceschetti-Klein or Franceschetti-Zwahlen-Klein, mandibulo-facial dysostosis or first arc syndrome, is a dominant autosomic disorder of the craniofacial development and may have innumerous clinical manifestations. In the case we present with this syndrome, we observed multiple craniofacial malformations, and also a severe scoliosis, external auditive duct atresia, bilateral preauricular papilomas and right hand pre axial polydactilia.

Usefulness of Videofluoroscopic Swallow Study in Treacher Collins Syndrome With Cleft Palate: A Case Report

A 3-year-old girl had multiple anomalies compatible with Treacher Collins Syndrome (TCS). From the neonatal period, sucking was poor, making tube feeding necessary. Excessive saliva was retained in the oral cavity. Nasal leakage caused by the cleft palate was observed when she spoke. The initial videofluoroscopic swallow study (VFSS) showed a poor posterior bolus transit and nasopharyngeal regurgitation. A delayed swallow reflex and bolus stasis at the vallecular and pyriform sinuses were recognized. Based on the VFSS findings, the patient underwent palatoplasty at 20 months of age. At approximately 23 months of age, a follow-up VFSS was performed; poor posterior bolus transit, nasopharyngeal regurgitation, and delayed swallow reflex were not observed. Finally, the patient was able to eat ground or chopped foods and solid foods orally. We deem VFSS to be helpful in deciding the appropriate management of dysphagia in TCS.

A Novel Insertion in Exon 23 of the TCOF1 Gene in a Newborn Infant with Treacher Collins Syndrome

Treacher Collins syndrome (TCS) is the most common and well known mandibulofacial dysostosis with characteristic clinical features including downward slanting of palpebral fissures, coloboma of the lower eyelid, hypoplastic zygomatic arches, micrognathia, macrostomia, microtia, and other deformities of the ears. TCS is caused by mutations in at least 3 genes involved in pre-rRNA transcription: TCOF1, POLR1D and POLR1C. We experienced a 1-day-old female infant with characteristic clinical features of TCS. A novel, heterozygotic mutation within the TCOF1 gene (c.3874_3875insG, p.Ala1292Glyfs*30) was identified to cause a premature stop codon.
