Table 1.
6-month postop mean laryngeal adductory pressure (LAP) values at 70-100 Hz for model RLN injury study groups. p-values based on comparison with pre-treatment baseline using t-test. NS, not significant; transx, transection; rot, rotation.

| A | Full transx, 0° rot | 8 | 0.56 | 0.11 | <0.001 |
| B | Full transx, 180° rot | 6 | 0.50 | 0.04 | <0.001 |
| C | Full transx, no repair | 5 | 0.00 | 0.00 | <0.001 |
| D | ½ transx | 6 | 1.08 | 0.11 | NS |
| E | Full crush | 7 | 1.05 | 0.10 | NS |
| F | ½ transx, ½ crush | 4 | 0.72 | 0.13 | 0.036 |
| G | Cautery | 6 | 0.61 | 0.15 | 0.001 |
| H | AD/AB divisions, 0° rot | 9 | 0.99 | 0.05 | NS |
| I | AD/AB divisions, 180° rot | 8 | 0.70 | 0.04 | <0.001 |
