Patients who presented with a focal neurological deficit (hemiparesis, monoparesis, and cranial nerve palsy) have an increased average change from pre- to postoperative serum concentration of the pro-inflammatory TNF-α by −0.64 units, of the pro-inflammatory IL-6 by 1.75 units, and by the anti-inflammatory IL-4 by −1.04 units compared to those who did not present with a focal neurological deficit{TNF-α (aCoef, −0.64; 95%CI, −1.25: -0.04), IL-6, (aCoef, −1.75; 95%CI, −3.32: −0.18), and IL-4 (aCoef, −1.04, 95%CI, −2.00: −1.08), p = 0.05} (Table 8). This evidence concerns the gene IL6 and cranial nerve palsy.
