Abstract

Background and Purpose. The effect of temporal lobe transection area, volume of postoperative gliosis, and surgical technique on patients' seizure-free outcome is unknown. The authors studied the effects of these variables on patients' seizure-free outcome. Methods. A retrospective review of magnetic resonance imaging examinations acquired 3 to 18 months after temporal lobe resection was carried out for 18 patients with intractable temporal robeseizures and known postsurgical outcomes for more than 2 years. The total volume of radiologically probable gliosis evident on axial proton-density-weighted images was calculated for each patient using software on an independent console. The total area of temporal robe surface transected by the scalpel was calculated as well. using sagittal T1-weighted images. The total volume of gliosis, the total area of transected temporal lobe, and the specific type of surgery (sparing vs no sparing of the superior temporal gyrus) were then correlated with the postsurgical outcome of the patients. An examiner with no prior knowledge of the patients' postsurgical outcomes carriedout the above calculations and measurements. The patients' postoperative outcome was defined using Engel classifications, and patients were divided into 2 groups: group A with Engel class 1 (n = 9) and group B with Engel classes 2-4 (n = 9). Results. The mean volumes of postoperative gliosis were not significantly different between group A (3592.3 mm(3)) and group B (4270mm(3)). The mean area of transected temporal robe was also similar betweengroup A (1865.2 mm(2)) and group B (1930 mm(2)). With regard to surgical technique, there were 5 patients who had the superior temporal gyrus resected and 13 who did not. Eighty percent of patients with the superior temporalgyrus resected were Engel class 1 or 2, whereas only 20% were of Engel class 3 or 4. Conclusions. The authors found no clear association between postoperative outcome and residual temporal lobe gliosis, the surgical technique, or the total area of temporal lobe transected by the scalpel.
