Objective: The present retrospective study explored the spectrum and characteristics of patients treated with orthognathic surgery at the Universidade Federal do Paraná, Brazil. Materials and method: Over a six-year period from July 2002 to July 2008, the records of 195 patients with dentofacial deformities who underwent orthognathic surgical procedures were followed up. Results: Mean patient age was 25.87 years (range 14 to 65 years) and the female to male ratio was 1.5:1. The predominant racial group was "white". Most patients belonged to the economically productive population. Sixty-two patients had complete dentition. Only 3.59% patients had local anesthesia (rapid palatal expansion). Transverse maxillary deficiency was the most common deformity, followed by maxillary anteroposterior deficiency associated with mandibular anteroposterior excess. Mandibular set-back was the intervention most frequently performed. The surgical procedures took an average of 3 hours 51 minutes and orthodontic treatments took an average of 44.48 months. Complications occurred in 22.57% of patients, the most common of which were permanent paresthesia of the lower lip (7.17%) and inadequate fracture reduction (5.12%). Conclusions: The findings included concepts that were useful for characterizing the profile of patients who undergo orthognathic surgery in southern Brazil. The results also may help to correctly develop protocols for patient care designed to improve the overall results of the procedures.

Objetivo: Este estudio retrospectivo explora el espectro y las características de los pacientes tratados con cirugía ortognática en la Universidade Federal do Paraná. Material y método: A lo largo de 6 años, a partir de julio de 2002 hasta julio de 2008, se efectuó el seguimiento de 195 pacientes con deformidades dentofaciales que se sometieron a procedimientos de cirugía ortognática. Resultados: La edad media de los pacientes fue de 25,87 años (de 14 a 65) y la proporción de mujeres y hombres fue de 1,5:1. El grupo racial predominante fue el "blanco". La mayoría de los pacientes eran parte de la población económicamente productiva. Sesenta y dos pacientes tenían la dentadura completa. Sólo el 3,59% de los pacientes fueron sometidos a anestesia local (expansión rápida de paladar). La deficiencia transversal maxilar fue la deformidad más común, seguida por la deficiencia anteroposterior del maxilar asociado con el exceso anteroposterior del maxilar inferior. La cirugía más realizada fue el retroceso mandibular. El procedimiento de cirugía duró una media de 3 h y 51 min, y el tratamiento de ortodoncia se prolongó 44,48 meses. Hubo complicaciones en el 22,57% de los pacientes, y las más habituales fueron parestesias (7,17%) y reducción inadecuada de la fractura (5,12%). Conclusiones: Los resultados de esta investigación muestran algunos conceptos que pueden caracterizar el perfil ortognático de los pacientes en el sur de Brasil. También tiene como objetivo colaborar en la correcta instauración de protocolos de cuidado de los pacientes a fin de mejorar los resultados de los procedimientos.

OBJECTIVE: The purpose of this study was to perform a clinical retrospective analysis of the etiology, incidence and treatment of selected oral and maxillofacial injuries in Brazilian children and adolescents. MATERIAL AND METHODS: This study was conducted during a 14-year period between 1986 and 2000. All patients were admitted to Hospital XV in the city of Curitiba, State of Paraná. Age, gender, monthly distribution, etiology, soft injuries, associated injuries, site of fractures and methods of treatment were reviewed. RESULTS: Of the total of 350 patients of all ages treated for facial injuries, 29.42% were within the age range of the study (0 to 18 years). Mean age was 10.61. Of the patients, 63.1% were male. The most common cause of injury was accidental falls (37.87%), followed by bicycle and motorcycle accidents (21.36%). Of the 103 patients, 88.34% had single injuries. Mandibular fractures were the most common and the condylar region was particularly affected. CONCLUSIONS: Facial trauma is a relatively common occurrence in children. The study indicates that fractures in children and adolescents differ quite considerably from an adult population.
