Percentage of Patients with Postoperative Seizures Based on LI Determined Using Coronal Images
| Lobe | LI = 0 | LI < 40* | LI ≥ 40 |
|---|---|---|---|
| Entire temporal | 2/6 (33) | 9/37 (24) | 7/45 (16) |
| Medial temporal | 5/20 (25) | 8/36 (22) | 8/41 (20) |
| Lateral temporal | 4/8 (50) | 10/39 (26) | 6/38 (16) |
| Inferior temporal | 2/10 (20) | 8/31 (26) | 8/46 (17) |
↵* Number of patients includes those with LI = 0.
Values are expressed as number of patients with postoperative seizures over total number of patients with that value of LI; percentage is given in parentheses. For purposes of this analysis, absolute value of LI was calculated to combine patients with right and left temporal lobe epilepsy. The higher the LI, the greater is asymmetry. Value of 40 was used as cutoff point because it corresponds to difference of 1 point on qualitative score between the 2 sides (thus, scores less than 40 represent least degree of asymmetry possible).
