Diseno del estudio: Estudio retrospectivo de una serie de casos. Entre 2006 y 2009, se revisaron las historias clinicas de 293.090 pacientes. Los datos de los pacientes con lesiones de traumatismo en la cara que fueron recogidos y evaluados fueron: la edad, el sexo, el dia y el mes del ingreso hospitalario, la causa de la lesion, la localizacion anatomica, el tipo de lesion y la presencia de lesiones asociadas. Resultados: Se recogieron un total de 7.617 pacientes con 8.944 heridas. La relacion hombre:mujer fue 1,7:1. Se observo la afectacion con mayor frecuencia de los ninos en edad preescolar. La causa principal de la lesion fueron las caidas, siendo las lesiones de los tejidos blandos el tipo mas comun de lesion. Las lesiones asociadas ocurrieron en el 11% de los casos. Conclusiones: El traumatismo facial presenta una frecuencia significativa en el grupo de ninos chilenos estudiados. Los ninos en edad preescolar eran propensos a presentar un traumatismo facial de severidad leve asociada a las caidas.

Usamos telerradiografias de perfil tomadas en posicion habitual de cabeza, utilizando los analisis cefalometricos de Delaire y Solow. Los resultados obtenidos permitieron concluir que existe una relacion directa entre la posicion retruida mandibular que presentan los pacientes con dismorfosis dentoesqueletal clase II y la postura cervical, determinando que entre mas posterior es la posicion mandibular, mayor es la extension anterior de la columna cervical (AU)

Cómo determinar la posición correcta de los maxilares, y 2. Etipoatogenia. Se revisan los criterios que aplica el análisis del Prof. J. delaire, para determinar la correcta ubicación de las bases esqueletales en el tratamiento ortopédico y/o quirúrgico, basado en la evolución filogenética y ontogenética del macizo cráneo-facial

Se reviso las historias clinicas de 146 pacientes operados de fisura labio/maxilo/palatina entre los anos 1997 y 2002. Despues de excluir los pacientes sindromicos y de reconstruccion secundaria quedaron 50 casos de reconstruccion primaria que fueron analizados para este estudio. Se estudio la edad del paciente en el momento de la operacion, tipo de cirugia realizada, duracion de la intervencion, tiempo de estancia postoperatoria y morbilidad a corto plazo. La estancia hospitalaria promedio fue de 26,4 horas (1,10 dias), con un rango de 24-72 horas. El 90,47% (76 intervenciones) tuvieron un periodo postoperatorio hospitalario de 24 horas, el 8,33% (7 intervenciones) de 48 horas y el 1,19% (1 intervencion) de 72 horas. La tasa de complicaciones fue de 10,18%, la cual incluyo 4 dehiscencias totales y 3 dehiscencias parciales velopalatinas y 4 dehiscencias parciales en paladar duro. No se requirieron transfusiones sanguineas ni se produjeron infecciones en el postoperatorio. Los pacientes no debieron ser reingresados por sangrado, compromiso respiratorio o inadecuada alimentacion por via bucal. Los autores sostienen que un postoperatorio de 24 horas permite optimizar los recursos existentes en las instituciones de salud sin olvidar el bienestar y seguridad del paciente. La decision del alta hospitalaria debe permanecer a criterio del cirujano tratante. EnglishThe pediatric surgery service at Dr. Felix Bulnes Cerda Hospital from Santiago, Chile uses same-day admission with 24 hours observation postoperatively. The records of 146 patient with cleft lip/palate repair from 1997 through 2002 were studied. After excluding syndromic patients and secondary surgical cases 50 patients remained in this study. Age at the time of operation, operation performed, length of stay, length of operations and short-time morbidity were studied. Mean hospital stay was 26.4 hours, with a range of 24-72 hours. The 90.74% (76 operations) of patients stayed 24 hours postoperatively, 8.33% (7 operations) stayed 48 hours and 1.19% (1 operation) stayed 72 hours. The overall complication rate was 10.18%, which included 4 total and 3 partial velar dehiscences and 4 partial palate dehiscences. No blood transfussions were needed, and no infections were noted postoperatively. No patients required readmission postoperatively for bleeding, respiratory compromise or inadequate oral intake. The authors advocate a 24 hours observation postoperatively for improving the resources but taking account patients wealthy. The decision to discharge a patient must always be left to the treating surgeon.

Methods: The lateral cephalograms of 76 subjects, comprising patients with operated unilateral cleft lip and palate (OpC) and a group matched for sex and age without cleft, were used. Thirteen landmarks were used as variables in geometric morphometric tests quantifying and describing overall shape variation, differences between group means, allometry, and upperlower face covariation. Results: The OpC group showed broader shape variations including noncleft group characteristics, but mainly a retrognathic maxilla, a vertically elongated face, a more open mandibular angle, and a more closed basicranial angle. Group means differed mainly in the maxillomandibular relationships. Allometry differed between groups, with the smallest OpC patients showing the most altered morphology. Upper and lower face covariation was stronger in the OpC group, showing mainly vertical changes in the anterior face. Conclusions: Operated patients affected by clefts achieve a broad range of morphologies; the most altered were found in those with skeletal Class III and small size. Furthermore, their strongest upper and lower face shape covariation suggests that a harmonic dental occlusion could be a key factor in achieving "normal" craniofacial morphology. (Am J Orthod Dentofacial Orthop 2014;146:346-54) C lefts of the lip and palate (CLP) are common congenital anomalies. The incidence is highly variable among populations. The highest incidence is found in Asians and Native Americans, with 1 in 500 live births, and the lowest in Africans, with 1 in 2500 births; white, Hispanic, and Latin populations (among these, Chileans) have intermediate incidence of 1 in 1000 live births. 1-4 Cleft etiology is multifactorial, comprising both genetic and environmental factors acting during intrauterine development. 5-7 Unilateral CLP (UCLP) is the most common cleft type. 5,8 Morphologic alterations of operated patients with UCLP have been widely reported in the literature, of which changes in maxillomandibular relationship are the most prevalent, as described below. Since unoperated subjects have the potential to develop a "normal" (ie, skeletal Class I) maxillomandibular relationship, 9,10 it has been proposed that altered maxillomandibular relationships are caused by the effect of surgery, particularly lip closure, on the developing bone and sutures. 11-13 This has led to the proposal of different protocols for the surgical management of CLP that concur in the importance of reconstructing the muscular anatomy of the lip and the soft palate after the third month of age. 12,14-16 Despite the differences in surgical approaches and treatment protocols, the morphologic features in operated patients with UCLP tend to be uniform. In general,

An important part of the cranial and cervical tegument is innerved by superficial branches of the cervical plexus, which can be blocked by infiltration of anesthetic in a unique point locatable in the lateral region of the neck. An anesthetic technique was executed for blockage of tegumentary branches of the cervical plexus in a test series conformed by 15 healthy adults. The anesthesia was verified by means of tactile, pain and temperature tests, in five points over the dermatomes of the cervical plexus. Complete anesthesia was verified in 14 of the 15 patients. In all cases the anesthesia lasted at least 90 minutes, and there were no accidents or major complications associated to the execution of the technique. The notable anesthetic effect and adequate working time, summed with the low risk of accidents and complications, make this technique a good alternative for sensitive blockage of part of thecranial and cervical regions. Regional blockage of superficial branches of the cervical plexus is an effective and safe procedure, and can be used in some procedures in the estomatological ambit.
