目的：比较两种类型的颞叶切除术(TLR)后视野缺陷(VFD)的发生率，并发现VFD的发生率与切除的大小有关。方法：对50例内科难治性癫痫患者手术前后的视野检查结果进行分析。33例患者有典型的TLR，17例TLR有较少的外侧伸展。对34例患者的术后MRI进行了研究，评分方法是对颞叶12个区域的切除大小进行评分。结果：25名患者出现了室性心动过速。在经典TLR组中，33人中有16人发展为VFD，而另一组中17人中有9人发展为VFD。VFD组在所研究的最前面的间隙，在颞上回的切除点较高。结论：在所研究的手术方法之间，VFD的频率没有明显的差异。然而，分区分析揭示了颞上回前部切除的程度与VFD频率之间的关系。
Objectives - The frequency of visual field defects (VFD) after temporal lobe resections (TLR) was compared for two types of TLR and VFD frequency was correlated to resection size. Methods - Pre- and post-operative perimetry results were analysed for 50 patients with TLR for medically intractable epilepsy. Thirty-three patients had a classical TLR and 17 had a TLR with less lateral extension. Post-operative MRIs were studied in 34 patients by scoring resection size in 12 compartments in the temporal lobe. Results - Twenty-five patients developed a VFD. In the classical TLR group, 16 of 33 developed a VFD, compared with nine of 17 in the other group. The resection points were higher for the VFD group in the most anterior compartment studied, in the superior temporal gyrus. Conclusions - There was no clearcut difference in VFD frequency between the surgical methods studied. However, the compartmentalized analysis disclosed a relation between the extent of resection in the anterior part of the superior temporal gyrus and VFD frequency.
