“…In this context, the results of this study demonstrate that the mechanism of impaired ocular mobility in orbital floor fractures is different to what is widely claimed. Moreover, increased thickness of the rectus inferior muscle has been observed on the affected side in patients with orbital floor fractures [21]. When viewed in conjunction with our findings, this particular observation hints that the impaired ocular mobility in patients suffering from orbital floor fracture could potentially be a consequence of direct injury to the rectus inferior muscle or ischemia triggered by the swelling of surrounding tissues, rather than physical entrapment of the muscle itself.…”

Background: Orbital floor fractures involve damage to the orbital floor but not the infraorbital margin. Despite intensive research, they remain a controversial topic. The aim of this study was to investigate the relationship between parameters gathered by means of computed tomography (CT), the clinical presentation, and treatment outcomes, in patients suffering from orbital floor fractures. Methods: Forty patients with orbital floor fractures were included in this study. Information regarding diplopia, impaired ocular mobility, asymmetric eyeball placement, and infraorbital paresis was gathered from the medical records. Nine CT-based parameters were assessed. Two parameters were calculated, based on them. The follow-up data of 30 patients were analyzed. The results were statistically evaluated. The significance level was p < 0.05. Results: Statistical evaluation revealed multiple correlations between CT-based findings, symptoms, and treatment results. Among others, the hernia into the maxillary sinus was significantly larger in patients without improvement in infraorbital paresis (p = 0.0031) and without improvement in assymetric eyeball placement (p = 0.0037). There was no correlation between the entrapment of the rectus inferior muscle and impaired ocular mobility (p = 0.664431; p = 0.420289) and between the direct fracture of the infraorbital canal and infraorbital paresis (p = 0.371102). Conclusions: The widely assumed thesis that impaired ocular mobility in orbital fractures is caused by entrapment of the rectus inferior muscle is disproved by CT-based data. CT-based findings, symptoms, and treatment results in patients with orbital floor fractures were significantly correlated. A large hernia may be a negative prognostic factor.

“…On the other hand, Magnetic Resonance Imaging (MRI) has several advantages compared with CT: no radiation, better evaluation of soft tissue, and functional evaluation of orbital contents. 1 , 41 In the algorithm, CT, which has the characteristic of short imaging time, was adopted as the first imaging modality. In this study, all patients were able to undergo urgent CT evaluation of orbital conditions.…”

“…O dano e a união ao tecido circundante dos músculos, posição anormal dos músculos, deficiência óssea orbital e degeneração do tecido adiposo orbital são também causas significativas de diplopia, que estão envolvidos em um modo complexo e resultam em movimentos incomuns do globo ocular 10 .…”

Os traumas de face ocorrem por forças externas lesionando o corpo, podendo eles ser locais, gerais ou concomitantes. A etiologia do traumatismo orbitário é diversificada como: quedas, queimaduras e agressões, sendo considerada uma das principais causas de morte no mundo de acordo com Organização Mundial da Saúde (OMS). As fraturas faciais podem se dividir em fraturas dos terço superior, terço médio e terço inferior. As fraturas do tipo Blow-outmantêm as margens orbitais integra, envolvendo apenas parede orbital inferior e ou média. Diplopia e enoftalmia são complicações bem características de traumas orbitais. O objetivo do artigo é identificar as principais lesões ocasionadas por fraturas orbitárias e apontar o diagnóstico e tratamento das lesões. Trata-se de uma revisão de literatura do tipo descritiva, com os dados colhidos nas bases de dados PubMed, SciElo, Lilacs, Google Acadêmico, selecionando artigos entre o ano de 2008 – 2018, de língua inglesa, portuguesa e espanhola, disponíveis para download nas bases de dados citadas. Os exames de imagem como a Tomografia Computadorizada é de suma importância para o diagnóstico devido seu detalhamento. Alguns sinais clínicos são: diplopia, enoftalmia, hipoftalmia ou mobilidade muscular ocular prejudicada. O tratamento ainda varia muito entre os cirurgiões.Descritores: Diplopia; Fraturas Ósseas; Órbita; Traumatismo do Nervo Abducente; Nervo Óptico.ReferênciasRamos JC, Almeida MLD, Alencar YCG, de Sousa Filho LF, Figueiredo CHMC, Almeida MSC.
