A retrospective survey over one year of a hospital emergency room population, seen at an oral and maxillofacial surgery clinic, found 271 patients (4.6% of the total population) with dentoalveolar injuries. A very large number of injuries occurred to children between the ages of 0 and 5 years (42.1%), and there was a significant number of injured patients in the adult population (19.1%). The ratio of male to female was 1.9:1. The leading cause of injury was falls (59.8%). The largest number of injuries was seen during summer. The diagnoses were lateral luxation (27.3%), concussion (17.3%), exarticulation (14.3%), tooth fracture (12.5%), intrusive luxation (11.1%), fracture of alveolar process (7.4%), extrusive luxation (3.7%), and cases with more than one diagnosis (6.3%). Most of the involved teeth were maxillary central incisors, in both dentitions.
The purpose of this retrospective study was to evaluate contributing factors in patients requiring surgical retreatment of mandibular fractures. Of all the patients with mandibular fractures who were treated using internal fixation at a trauma hospital over a seven-year period, 20 patients (4.7%) required a second surgery and thus composed the "reoperated" group. The control group comprised 42 consecutive patients with mandibular fractures who were treated at the same clinic and who healed without complications. Medical charts were reviewed for gender, age, substance abuse history, dental condition, etiology, location of fracture, degree of fragmentation, fracture exposure, teeth in the fracture line, associated facial fractures, polytrauma, time elapsed between trauma and initial treatment, surgical approach and fixation system. Statistical analyses were performed using the Statistical Package for Social Sciences (SPSS) version 20.0; descriptive statistics and the chi-squared test were used to determine differences between groups. Significant differences in substance abuse (p = 0.006), dental condition (p < 0.001), location of fracture (p = 0.010), degree of fragmentation (p = 0.003) and fracture exposure (p < 0.001) were found. With regard to age and time elapsed between trauma and initial treatment, older patients (31.4 years, SD = 11.1) and a delay in fracture repair (19.1 days, SD = 18.7) were more likely to be associated with reoperation. It was concluded that substance abuse, age, dental condition, location of fracture, degree of fragmentation, fracture exposure and the time between trauma and initial treatment should be considered contributing factors to the occurrence of complications that require surgical retreatment of mandibular fractures.
RESUMOTema: ferimentos causados por projéteis de arma de fogo apresentam alta incidência na região da cabeça e face. A articulação temporomandibular pode estar envolvida, além de estruturas anatômi-cas importantes como o nervo facial, necessitando de equipe multidisciplinar para efetuar tratamento adequado. Procedimentos: apresentação de caso clínico de fratura condilar cominutiva causada por projétil de arma de fogo tratado de forma não-cirúrgica associado à terapia miofuncional orofacial. Paciente encaminhado para avaliação e procedimentos fonoaudiológicos após conduta da equipe de cirurgia bucomaxilofacial, sem remoção do projétil, alojado superficialmente, próximo da origem do músculo esternocleidomastóideo à direita, com fratura condilar cominutiva e lesão do nervo facial. Foram aspectos observados em avaliação: mordida aberta anterior, importante redução da amplitude dos movimentos mandibulares com desvios para o lado acometido, ausência de lateralidade contralateral, dor muscular, paralisia e parestesia em terço médio e superior da hemiface direita. Realizadas sessões de terapia miofuncional seguindo protocolo específico para traumas de face constando de: drenagem de edema; manipulações na musculatura levantadora da mandíbula ipsilateral; ampliação e correção dos movimentos mandibulares; procedimentos específicos referentes à paralisia facial e reorganização funcional direcionada. Resultados: após oito semanas de terapia os resultados obtidos mostram restabelecimento de amplitude e da simetria dos movimentos mandibulares, reorganização da mastigação, adequação da deglutição e fala, remissão da sintomatologia dolorosa e remissão da paralisia do terço médio. Conclusão: o tratamento conservador da fratura por meio da terapia miofuncional orofacial resultou na reabilitação funcional da mandíbula e face dirigindo os movimentos e estimulando a adequação das funções estomatognáticas.
Cervical necrotizing fasciitis (CNF) is an uncommon, potentially fatal soft tissue infection with rapid progression characterized by necrosis in the subcutaneous tissue and fascia. A case of CNF of odontogenic origin in a diabetic patient, complicated by alcohol dependence and tobacco abuse, is presented with a literature review. The emergency procedure comprised hydration, colloid administration, glycemic control and broad spectrum antibiotic therapy, followed by aggressive surgical debridement. Necrosis in the platysma muscle was verified by histopathologic analysis. Reconstructive surgery was performed after suppressing the infection, and the wound was closed with an autologous skin graft. The patient had a long hospital stay, in part because the substance abuse led to a difficult recovery. The principles of early diagnosis, aggressive surgical debridement, broad-spectrum antibiotic therapy and intensive supportive care in the treatment of CNF were confirmed in the present case. It was concluded that given the occurrence of CNF in the presence of diabetes mellitus and abuse of substances such as alcohol and tobacco, the health care professional should consider a stronger response to treatment and longer hospitalization.
