RESUMO
ABSTRACT: A series of skeletal and dentoalveolar/occlusal criteria were proposed for choosing the treatment modality for the management of midface hypoplasia in cleft lip/palate patients, focusing on functional improvement, aesthetics, and minimizing the risk of recurrence and secondary alterations. For which, 42 patients with nonsyndromic cleft lip/palate, all with previous primary lip/palate surgeries and without previous osteotomies, were analyzed. Orthognathic surgery (OS) (nâ=â24) and maxillary distraction osteogenesis (nâ=â18) with anterior segmental osteotomies (segmental distraction osteogenesis [SD]), alveolar transport disc (TD), and midface total distraction osteogenesis (TDO) by modified Le Fort III osteotomy was done.The average of maxillary advancement for OS was 5.58â±â0.83âmm, for SD 9.4â±â0.89âmm, for TD 8.00â±â1.00âmm, and for TDO was 8.13â±â1.55âmm.In the presence of infraorbital and/or zygomatic hypoplasia, TDO was performed using skeletal anchorage, with the requirement of occlusal stability in dental cast in occlusion. In short maxillary arch without dental cast feasibility in occlusion, hypodontia/agenesis or absence of premaxilla, TD and SD was performed. There was only 1âmm of recurrence in 1 patient of each group. Changes in speech were detected in 2 patients in the OS group (8.3%). Orthognathic surgery can be indicated for advancements ≤7âmm not requiring orbito-zygomatic advancement, whereas distraction osteogenesis can be indicated for advances >8âmm with or without the need for orbito-zygomatic advancement, in addition with other dentoalveolar factors and velopharyngeal function.

The objective of this work is to describe a segmental maxillary distraction osteogenesis (SDO) with segmental Lefort I with an inexpensive device.Four patients who presented severe class III and maxillary hypoplasia due to cleft lip and palate sequel were treated. A SDO was performed using a dental-anchored Hyrax device, achieving enlargement of the upper jaw without altering speech, with adequate and stable occlusion. Dental implants in a new formed bone were installed.The authors can conclude that SDO is a good treatment alternative for patients with maxillary hypoplasia. It preserves velopharyngeal function and is a stable treatment, maintaining the overjet achieved with distraction osteogenesis, without changes in posterior occlusion. The open bite generated with tooth-borne devices can be solved with temporary anchorage devices and intermaxillary elastics during consolidation phase. Modified Hyrax device allows expanding and moving forward the maxillary arch, with a low cost.

ABSTRACT: The objective of the study was to describe the epidemiologic profile of patients with non-syndromic cleft palate according to factors that involve the mother. Observational, retrospective and analytical study from data obtained of non-syndromic cleft lip palate cases. The type of cleft lip and palate (CLP) and the variables that involve the mother were classified. In this analysis 236 fulfilled clinical records from patients were evaluated; 56,60 % correspond to male and 43,40 % to female. Most births occurred in 2011 (15,57%), cleft palate is the most prevalent (44,92 %), at the moment of birth mothers were 21-25 years old (26,67 %), most of the mothers consumed alcohol or tobacco during the first trimester of pregnancy (80,50 % and 87,50 %, respectively), and 41,33% worked in agriculture related jobs. In conclusion post natural catastrophe stress, chronic diseases, consumption of drugs, smoking and alcohol habits and exposure to pesticides can be considered as a risk factor for having a child with CLP.
RESUMO
RESUMEN: La fisura labio máxilo palatina (FLMP) es un problema de salud pública en Chile. Consiste en la falta de fusión del labio y/o los procesos palatinos, generando un desequilibrio músculo esqueletal que impide el desarrollo facial normal. Afectando algunas funciones vitales como respiración, succión y deglución pudiendo ocasionar problemas nutricionales. Evaluar el crecimiento estaturo ponderal y acceso a lactancia materna de niños con fisura labio máxilo palatina (FLMP) comparados con niños sin fisura durante el primer año de vida. Estudio de tipo observacional, analítico de cohorte retrospectivo a partir de los datos provenientes de entrevistas a las madres de niños con FLMP no sindrómica atendidos durante el año 2017 y niños sin FLMP perteneciente a la misma región. En niño/as sin FLMP predomina la lactancia materna exclusiva y en niños/as con FLMP lactancia mixta (47,7 %) y uso exclusivo de leche de fórmula (33.3 %). Los niños/ as con FLMP durante el primer año de vida pesan en promedio 0,45 Kg y miden 1,11 cm menos que los niños/as sin fisura. Los niños/as con FLMP reciben menos lactancia materna y tienen un menor crecimiento estaturo ponderal que los niños/sin FLMP durante el primer año de vida, siendo el peso el parámetro de crecimiento más afectado.
ABSTRACT: The maxillary cleft lip and palate fissure (CLPF) is a public health problem in Chile. It involves the lack of fusion of the lip and / or the palatal processes, generating a skeletal muscle imbalance that prevents normal facial development, further affecting vital functions such as breathing, sucking and swallowing. It may also cause nutritional problems. An observational, analytical, retrospective cohort study was carried out, to assess the growth in weight status of breastfeeding infants with maxillary CLPF, and compare it with children without fissure during the first year of life. The study was based on data obtained in 2017, from interviews with mothers of infants with non-syndromic CLPF, and those without CLPF from the same region in Chile. In children without CLPF, exclusive breastfeeding predominated, while children with CLPF received mixed breastfeeding (47.7 %) and exclusive use of formula milk (33.3 %). During the first year of life, infants with CLPF weighed an average of 0.45 kg and measured 1.11 cm less, than children without fissures. Children with CLPF received less breastfeeding and ranked lower in weight and growth than children / without CLPF during the same time period, with weight being the most affected growth parameter.

RESUMEN: Objetivo: Determinar los tipos de dismorfosis dentofaciales (DDF) operados en el Hospital Clínico San Borja Arriarán, Santiago, Chile (HCSBA) entre los años 1993 - 2015 y su distribución por sexo y edad al momento de la intervención quirúrgica. Material y Método: Estudio retrospectivo, el criterio de inclusión fue diagnóstico de DDF (clases II o III esqueletal) no asociado a síndrome. La edad de los pacientes se describió con promedio y desviación estándar y el sexo con porcentajes. Análisis estadístico se realizó mediante test de Proporciones, T de Student, prueba Exacta de Fisher y modelo multivariado. Se consideró un valor p<0,05 como significativo. Resultados: De 1.008 pacientes operados por el equipo de cirugía oral y máxilofacial entre 1993 - 2015, 570 (56,5%) fueron intervenidos por cirugía ortognática para corrección de DDF. 76 (13,3%) por DDF tipo II y 494 (86,7%) por DDF tipo III. El mayor porcentaje fueron 366 mujeres (64,2%), la edad promedio fue 26,9 (DS 10,8) años en clase II y 22,8 (DS 6,8) años en clase III. Todas estas diferencias fueron estadísticamente significativas. El rango de edad con mayor porcentaje de operaciones fue entre los 20 - 30 años (55,6%). Conclusión: La DDF más frecuentemente operada es la DDF III y el mayor porcentaje son mujeres entre los 20 - 30 años.
ABSTRACT: Objective: To determine main characteristics of dentofacial deformities (DDF) patients treated with orthognathic surgery at San Borja Arriarán Clinical Hospital, Santiago, Chile (HCSBA) during the last 23 years. Materials and methods: This is a retrospective study, the cases are registered in the electronic database of the oral and maxillofacial service of the HCSBA between 1993 - 2015. Inclusion criteria were patients with a diagnosis of DDF (skeletal class II or III) - not associated with syndromes- who went under orthognathic surgery since 1993 to 2015. Characteristics analysed included: type of DDF, sex and age. Results were described using percentage, mean and standard deviation. Proportion, Student's Ttest, Exact Fisher Test and a multivariate model were utilized for statistical analysis. A p-value <0.05 was considered significant. Results: A total of 1.008 patients were surgically treated. During this period 570 (56,5%) patients underwent orthognathic surgery to correct DDF, 76 (13.3%) for DDF type II and 494 (86.7%) for DDF type III. Most patients intervened were women 366 (64.2%). The mean age was of 23.3 years; 26.9 (SD 10.8) years in class II and 22.8 SD (6.8) years in class III. All differences were statistically significant. The age range with the highest percentage of operations was between 20 - 30 years (55.6%). Conclusion: The most frequently operated DDF is type III, the highest percentage being women and young adults between 20 - 30 years.

Infant facial fracture incidence is low. Most reported cases affect the jaw and are single fractures. We present a twenty-two-month old patient, who had a high-energy car accident. Among other injures, she suffered a multiple mandibular fracture: bicondylar, left body and right parasymphyseal. Stable internal fixation of parasymphyseal and body mandibular fracture was performed on the third day. Condylar fractures had a functional treatment with switching elastic traction to prevent ankylosis. Computed tomography (CT) showed mandibular condyles remodelling after six months. Clinical examination showed that mandibular movement ranges were preserved without alteration. Successful treatment of paediatric patients is based on the achievement of an adequate anatomic reduction and the stability of the fracture, allowing opportune form and function recovery, in order to assure further development of dental and facial structures...
La incidencia de fracturas faciales en infantes es baja. Los casos reportados muestran que afectan principalmente a la mandíbula y corresponden a fracturas únicas. Presentamos una paciente de 22 meses de edad, que sufre accidente automovilístico. Resulta entre otros, con múltiples frac-turas mandibulares: bicondílea, de cuerpo izquierdo y parasinfisiaria derecha. Al tercer día se realiza fijación interna estable en fractura parasinfisiaria y de cuerpo mandibular y tratamiento funcional de las frac-turas condíleas a través de tracción elástica alterna-da, para prevenir la anquilosis. Tomografía computa-da a los seis meses muestra remodelación de los cóndilos mandibulares. Al examen clínico los rangos de movimiento mandibular están conservados y sin alteración. El éxito del tratamiento en pacientes pediátricos se basa en obtener una adecuada reducción anatómica y estabilidad de la fractura, que permita recuperar oportunamente forma y función, asegurando el futuro desarrollo de las estructuras dentarias y faciales.
