Table 2 Surgical outcomes and postoperative complications in vestibular schwannoma resection.
| Outcome/complication | More-bleeding Group (n=15) | Less-bleeding Group (n=15) | P-value |
|---|---|---|---|
| Total resection achieved [n, (%)] | 9 (60%) | 12 (80%) | 0.25 |
| Subtotal resection [n, (%)] | 6 (40%) | 3 (20%) | 0.25 |
| Extent of resection (mean% ±SD) | 92.5±5.4 | 97.3±3.2 | 0.05 |
| Operative time (mean minutes ±SD) | 180±45 | 120±40 | 0.02 |
| Estimated blood loss (mean mL ±SD) | 800±150 | 450±120 | 0.01 |
| Intratumoral hemorrhage [n, (%)] | 6 (40%) | 1 (6.7%) | 0.02 |
| Peritumoral edema [n, (%)] | 6 (40%) | 1 (6.7%) | 0.02 |
| Cranial nerve deficits [n, (%)] | 5 (33.3%) | 3 (20%) | 0.4 |
| CSF leak [n, (%)] | 2 (13.3%) | 1 (6.7%) | 0.5 |
| Wound infection (n,%) | 1 (6.7%) | 1 (6.7%) | 1.0 |
| Other complications (hydrocephalus) [n, (%)] | 2 (13.3%) | 1 (6.7%) | 0.5 |
| CSF – cerebrospinal fluid; SD – standard deviation. | |||
