We report our findings in a case of ophthalmoplegia caused by a transorbital penetrating brainstem injury. An 8-year-old boy was accidentally injured by a broken fishing fiberglass pole which penetrated through the right orbit and entered the brainstem. Magnetic resonance imaging showed a linear wound that entered and passed through the pons obliquely and reached the fourth cerebral ventricle and cerebellar vermis. He had a left-sided hemiplegia and left facial nerve palsy and was diagnosed with "one-and-a-half syndrome". His hemiplegia and left facial nerve palsy resolved in 2 weeks leaving only a left abducens nerve palsy. The eye position and eye movements fully recovered within 3 months. These findings suggest a good prognosis for this type of trauma unless life-threatening changes develop.
我们报告了一例经眶穿透性脑干损伤导致眼肌麻痹的病例的研究结果。一名8岁男孩被一根折断的钓鱼玻璃纤维杆意外刺伤，该杆穿过右侧眼眶并进入脑干。磁共振成像显示一条线性伤口，斜向进入并穿过脑桥，到达第四脑室和小脑蚓部。他患有左侧偏瘫和左侧面神经麻痹，被诊断为“一个半综合征”。他的偏瘫和左侧面神经麻痹在2周内消失，仅遗留左侧外展神经麻痹。眼部位置和眼球运动在3个月内完全恢复。这些发现表明，除非出现危及生命的变化，这类创伤的预后良好。
