PATTERNS OF FACIAL FRACTURES AND ASSOCIATED SOFT TISSUE INJURIES: A RETROSPECTIVE STUDY ON 1007 PATIENTS.

Background: Knowing the severity of a pathology in a population helps to both establish a rapid diagnosis and to prepare medical staff to provide adequate and complete treatment. The aim of this study was to determine the patterns of maxillofacial fractures and their associated soft tissue injuries in order to identify the specific types of maxillofacial fractures with the highest incidence of associated soft tissue injuries. Methods: A 10-year retrospective evaluation of maxillofacial trauma was performed on 1007 patients. All 1007 patients were clinically and paraclinically confirmed to have facial skeletal injuries. Results: The highest incidence of maxillofacial fractures was found in the mandible (62.16%), the mandibular angle being the most frequently involved (28.84%). Most of the fractures were complete (97.82%), displaced (87.98%) and closed (86.30%). Hematoma was the most common associated soft tissue injury (44.79%). In mandibular trauma, the incidence of hematoma and laceration was the highest in angle and simultaneous multiple fracture lines (p=0.002). In the midface, hematoma was more frequently associated with non-comminuted zygomatic bone fractures (p=0.003), while laceration was associated with multiple underlying fracture lines (p=0.002). Conclusions: Patients presenting with hematomas will most frequently have an underlying single closed fracture line, while patients with lacerations will most frequently present underlying multiple and displaced fractures.

An epidemiological analysis of maxillofacial fractures: a 10-year cross-sectional cohort retrospective study of 1007 patients.

BACKGROUND: Epidemiological data is providing vital indicators for organizing the financial resources related to a particular type of trauma, estimating expenses and training of dental practioners and ambulatory medical staff for collaboration with a certain pattern of patients. Knowing the etiology and epidemiology of a certain pathology is significant for approaching its means of prevention. METHODS: A 10-year retrospective statistical analysis of 1007 patients with maxillofacial fractures treated in a University Clinic of Oral and Maxillofacial Surgery in Romania was performed. The data were extracted from patients' medical records. Statistical analysis was performed. A value of p < 0.05 was considered statistically significant. RESULTS: The incidence of maxillofacial fractures was high among patients in the 20-29 age group (35.9%). Male patients (90.57%, M:F = 9.6:1), having a low level of education (46.60%) and living in urban areas (53.50%) were more affected. The main cause of maxillofacial fractures was interpersonal violence (59.37%), both in the mandibular and midface topographic regions (p = 0.001, p = 0.002). In urban areas, fractures caused by interpersonal violence and road traffic accidents were predominant, while in rural areas, most of the fractures were due to interpersonal violence, domestic accidents, work accidents and animal attacks (p = 0.001). CONCLUSIONS: Interpersonal violence is the main cause of maxillofacial fractures having epidemic proportions. Male patients aged 20-29 years with a low level of education represent the major risk category. Considering the wide area of interpersonal aggression, both the medical staff in the hospital and in the dental offices must be educated in order to collaborate with possible violent patients. Dentists must be prepared to work on a post-traumatic dento-periodontal field. Taking all measures to prevent inter-human aggression is imperative and will lead to a major decrease in maxillofacial fractures and an overall increase of oral health in a population.

The pathogenic microbial flora and its antibiotic susceptibility pattern in odontogenic infections.

Suppurative head and neck infections of odontogenic origin are the most frequent type of head and neck infections. According to the literature, 7-10% of all antibiotics are currently prescribed for their treatment. Since penicillin was invented, the overall antibiotic sensitivity and resistance pattern of the isolated pathogenic microflora has continuously changed. The response of microorganisms to antibiotics and the development of resistance to their action is a purely evolutive process characterized by genetic mutations, acquisition of genetic material or alteration of gene expression and metabolic adaptations. All this makes challenging and difficult the correct choice of empirical antibiotic treatment for head and neck space infections even today. The aim of this paper was to evaluate the literature and to evidence the most frequent locations of odontogenic head and neck infections, the dominant pathogenic microbial flora, the genetic mutations and metabolic changes necessary for bacteria in order to aquire antibiotic resistance and as well its susceptibility and resistance to common antibiotics. We also aimed to highlight the possible changes in bacterial resistance to antibiotics over time, and to assess whether or not there is a need for fundamental changes in the empirical antibiotic treatment of these infections and show which these would be.
