Interpersonal Violence and Maxillofacial Injuries: Toward an Active Surveillance Proposal Through the Presentation Profile in Hospital Emergency Services.

To establish a set of variables that define a predictive profile of events of maxillofacial trauma resulting from interpersonal violence, we analyzed sociodemographic variables and clinical characteristics of injuries recorded in three tertiary care hospital centers in Chile. To assess the relation between categories, we applied a multiple correspondence analysis. We identified 567 cases. Two dimensions explained 53.4% of the model. The first dimension was composed of variables related to the severity of the injury: medical-legal prognosis (.574), type of trauma (.511), and the destination of the patient (.332); the second dimension was composed of variables related to the typology of interpersonal violence: type of violence (.398) and sex of the patient (.370). Two profiles were recognized: women, victims of domestic violence, with lesions affecting mainly soft tissues and not requiring hospitalization and men, victims of community violence, with lesions involving fractures associated with greater severity and requiring hospitalization. There are two key dimensions in the diagnosis of maxillofacial trauma resulting from interpersonal violence: severity of the injury and typology of the interpersonal violence. Exploring these predictive profiles can be a useful complement to the current screening tools of violence in clinical practice.

Oral Health-Related Quality of Life Changes in Patients with Dentofacial Deformities Class II and III after Orthognathic Surgery: A Systematic Review and Meta-Analysis.

Our aim was to assess the impact of combined orthodontic-surgical treatment on patients' oral health-related quality of life (OHRQoL) according to type of dentofacial deformities, by synthesizing the available evidence. METHODS: Search was conducted in the PubMed, Embase/MEDLINE, Scopus, and Cochrane databases. The eligibility criteria were studies that measured OHRQoL before-after orthognathic surgery, with results disaggregated by Class II and III. Two researchers independently performed the selection process, data extraction, and methodological quality assessment. Meta-analysis of the standard mean differences (SMD) was performed using random effect models. RESULTS: The search identified 1047 references. Thirteen studies met the inclusion criteria, and four were included in the meta-analysis. The SMD of OHRQL global score showed large improvement 4-7 months after surgery in Class II and III patients (2.09, 95% CI 0.68 to 3.49 and 1.96, 95% CI 1.22 to 2.70, respectively). The sensitivity analyses, excluding studies with weak methodological quality, showed that Class III patients' improvement in functional limitation was significantly higher than in Class II patients (SMD 0.57, 95% CI 0.12-1.02). CONCLUSIONS: There is not enough evidence to support differences between Class II and III patients in the OHRQoL impact after orthognathic surgery, but findings suggest lower improvement of some domains in Class II patients.

Changes in health-related quality of life after orthognathic surgery: a multicenter study.

OBJECTIVE: To evaluate changes in general and oral health-related quality of life (HRQoL) in patients with dentofacial deformity undergoing orthognathic surgery, and whether these changes vary according to type of deformity. MATERIAL AND METHODS: This is a prospective longitudinal multicenter study of patients with dentofacial deformities (n = 90). The Orthognathic Quality of Life Questionnaire (OQLQ), Oral Health Impact Profile (OHIP-14), and Short-Form Health Survey version2 (SF-36v2) were self-completed by patients before surgery, 3 and 6 months after orthognathic surgery. Change was tested using paired t-test, and compared between Class II and Class III of dentofacial deformity by unpaired t-test. The magnitude of change was examined estimating the standardized response mean (SRM). RESULTS: The OQLQ and OHIP-14 showed statistically significant improvements 6 months after surgery, compared with the pre-surgical evaluation, but the SF-36v2 only in the physical component summary. The SRM was large in OQLQ oral function (-1.11) and dentofacial facial aesthetics (-0.76) dimensions, and moderate in most of OHIP-14 dimensions. Differences in mean change between Class II and III were statistically significant for global scores of OQLQ (-10.08 vs -20.30, p = 0.0271) and OHIP-14 (-3.79 vs -10.56, p = 0.0144). CONCLUSIONS: A significant improvement was observed in oral HRQoL and in the physical component of general health in patients with dentofacial deformities Class II and III after orthognathic surgery. Improvement was greater among Class III than in Class II patients. CLINICAL RELEVANCE: These results provide patients, oral health care professionals, and planners with valuable information to make evidence-based decisions and facilitate shared clinical decision-making, taking into account the patients' perspective.

Cross-cultural adaptation and validation of the Spanish version of the Orthognathic Quality of Life Questionnaire for patients with dentofacial deformities.

OBJECTIVE: The aim of this study was to develop a Spanish version of the Orthognathic Quality of Life Questionnaire (OQLQ) that is conceptually equivalent to the original questionnaire, as well as acceptable, reliable, valid, and responsive for use in Chilean patients with dentofacial deformities. MATERIAL AND METHODS: The recommended standard methodology, with direct and back-translation, was used. A prospective longitudinal multicenter study of adult patients diagnosed with dentofacial deformity was carried out, self-administrating OQLQ, OHIP-14 (Oral Health Impact Profile), and SF-36 (Short Form 36 Health Survey) during the presurgery visit in order to examine construct validity. To evaluate reproducibility, questionnaires were re-administered 4 weeks later to subjects with a stable dental condition. Responsiveness was assessed among subjects followed up until 3 months after surgery. RESULTS: Of the 230 patients under presurgical orthodontic treatment included in the study, 216 completed the questionnaire, 142 formed the reliability sub-sample, and 30 were evaluated 3 months after surgery. Cronbach's alpha ranged from 0.78 to 0.94 and test-retest intraclass correlation coefficients ranged from 0.84 to 0.91 (p = 0.001) by dimension. The correlation matrix between OQLQ dimensions and SF-36 and OHIP-14 confirmed most of the associations previously hypothesized as moderate (rs > 0.4). Confirmatory factor analysis supported the same structure as the original instrument, considering four dimensions. Responsiveness was demonstrated by the large improvement observed in the global score 3 months after surgery: mean change ±SD = -15.1 ± 18.05 and standard response mean = -0.84 (p < 0.001). CONCLUSIONS: The Spanish version of OQLQ has demonstrated good levels of reliability, validity, and responsiveness - similar to those of the original questionnaire.

Trends of maxillofacial trauma: An update from the prospective register of a multicenter study in emergency services of Chile

Background: Determine the behavior of the maxillofacial trauma of adults treated in 3 tertiary care centers in the central zone of Chile. Material and Methods: descriptive, cross-sectional, multicenter study, based on the prospective records of maxillofacial trauma cases attended between May 2016 and April 2017 by dental and maxillofacial clinical teams of Adult Emergency Units of hospitals Dr. Sótero del Río (metropolitan region), Carlos Van Buren and Dr. Gustavo Fricke (region V). Age, sex, date of occurrence, type of trauma according to ICD-10, etiology, legal medical prognosis and associated injuries were recorded, stratifying by sex and age. Chi square and unpaired Wilcoxon tests were used to compare by groups. Results: 2.485 cases and 3.285 injuries were investigated. The male: female ratio was 1.7: 1 with age under 30 predominant, followed by older adults. Variability was observed in the yearly, weekly and daily presentation The highest frequencies were in January and September, weekends and at night. The main etiologies were violence (42.3%), falls (13.1%) and road traffic crashes (12.9%) with differences by age and sex (p <0.05). 31,9% of the injuries occurred in hard tissue, being fractures in nasal bones predominant (S02.2). Conclusions: the profile of the maxillofacial trauma in Chile seems to be mixed by age, affecting young people and the elderly. The male sex predominates; the main cause, which varies by age group, is violence. Their surveillance is possible from hospital emergency records
