目的:探讨CT,MRI对泪腺混合瘤的临床应用价值。方法:对术前行CT或MRI检查,术后经病理证实为泪腺混合瘤17例进行分析。结果:术后随访6mo～10a,14例未复发,3例复发(18%),1例为外院术前未行CT或MRI检查。结论:CT,MRI对泪腺混合瘤具有准确的定位、定性诊断价值,对手术入路选择、手术设计及术前准备也有着重要指导意义,对指导初次手术中连同包膜一次性完整切除病变,减少复发率,具有重要意义。

AIM:To investigate the clinical utility of CT and MRI for lacrimal mixed tumor. METHODS:Seventeen patients with lacrimal mixed tumor identified pathologically,who accepted CT or MRI inspection before the surgery,were analysed. RESULTS:The follow-up periods ranged from 6 months to 10 years.14 cases had no recurrence,and 3(18%) cases had recurrences.Of the cases with recurrences,1 case had not accepted CT or MRI inspection before the surgery in other hospital. CONCLUSION:CT and MRI have the accurate localization and the qualitative diagnosis value to the lacrimal mixed tumor.They also have important guiding meaning in the operative approach choice,the surgery design and the technique preparation.They have important meaning in instructing to completely remove the tumor in its capsule in the initial surgery and reducing the rate of recurrence.
