Ocular motility impairment associated with orbital trauma may have several causes and manifest with various clinical symptoms. In some cases orbital reconstructive surgery can be very challenging and the results are often unsatisfactory. The use of modern imaging techniques aids proper diagnosis and surgical planning.
The authors present the case of a 29-year-old male who sustained trauma to the left orbit. Orthoptic examination revealed limited supra- and infraduction of the left eye. The patient reported diplopia in upgaze and downgaze with primary position spared. Dynamic magnetic resonance imaging (dMRI) was performed, which revealed restriction of the left inferior rectus muscle in its central section. A patient-specific anatomical model was prepared on the basis of 3-dimensional computed tomography (CT) study of the intact orbit, which was used to prepare a custom pre-bent titanium mesh implant. The patient underwent reconstructive surgery of the orbital floor.
Modern imaging techniques such as dMRI and 3-dimensional CT reconstruction allow us to better understand the pathophysiology of orbital floor fractures and to precisely plan surgical treatment.
与眼眶外伤相关的眼球运动障碍可能有多种原因，并表现出各种不同的临床症状。在某些情况下，眼眶重建手术极具挑战性，且结果往往不尽人意。现代影像学技术的应用有助于明确诊断和手术规划。
作者报告了一例 29 岁男性患者，其左眼遭受外伤。斜视检查显示左眼上转和下转受限。患者主诉在第一眼位时上视和下视存在复视。行动态磁共振成像（dMRI）检查，结果显示左眼下直肌中段受限。根据完整眼眶的三维 CT 研究，制作了患者特定的解剖模型，用于准备定制的预弯钛网植入物。患者接受了眼眶底重建手术。
现代影像学技术如 dMRI 和三维 CT 重建，使我们能够更好地理解眼眶底骨折的病理生理学，并精确地规划手术治疗。
