| Intervention | No. of Patients | ||||
|---|---|---|---|---|---|
| Painless | Mild Pain | Moderate Pain | Severe Pain | Total | |
| Preoperative | 6 | 2 | 16 | 14 | 38 |
| Postoperative | 21 | 10 | 5 | 2 | 38 |
a Recovery was assessed by the VAS (VAS of 0, painless; 1–3, mild pain; 4–6, moderate pain; and 7–10, severe pain). Paired-samples t test showed a significant difference between the preoperative and postoperative periods (P <.001), suggesting that the fibrin glue therapy could significantly improve the symptoms of pain.
