方法：回顾分析2009-01/2012-12在我院首诊为动眼神经麻痹的患者，通过血糖、头颅计算机断层扫描(computed tomography， CT)、磁共振成像(magnetic resonance imaging， MRI)、磁共振血管造影(magnetic resonance angiography， MRA)、数字减影血管造影(digital subtraction angiography， DSA)等检查，分析动眼神经麻痹的原因及特点。

结果：动眼神经麻痹35例中，头部外伤10例(29%)，颅内炎性8例(23%)，糖尿病6例(17%)，颅内动脉瘤4例(11%)，颅内肿瘤4例(11%)，脑血管梗塞、脑血管出血、原因不明均为1例(3%)。

结论：引起动眼神经麻痹的病因复杂，以头部外伤最常见，其他原因还见于颅内炎性、糖尿病等。各病因在各年龄段分布具有一定特点，有针对性及时准确查明病因极为重要，是正确治疗的基础和关键。

METHODS: The outcomes in a series of 35 patients with oculomotor palsy from January, 2009 to December, 2012 in our hospital were retrospectively evaluated. Blood glucose, computed tomography(CT), magnetic resonance imaging(MRI), magnetic resonance angiography(MRA), and digital subtraction angiography(DSA)were underwent to analyze its causes and characteristics.

RESULTS: In 35 cases, causes were head injury in 10 patients(29%), intracalvarium inflammation in 8 cases(23%), diabetes in 6 cases(17%), intracranial aneurysm in 4 cases(11%), intracranial neoplasm in 4 cases(11%), cerebral infarction, cerebrovascular hemorrhage and unknown in 1 case(3%), respectively.

CONCLUSION: The causes resulting oculomotor palsy were multiplicity, head injury is the most common cause of oculomotor palsy. The other common causes include intracalvarium inflammation and diabetes mellitus. The causes exist some characteristics in different age stages, determine the causes is important extremely for treatment in correct.
