| Surgical Group | Status of Chorda Tympani Nerve (CT) | Status of Glossopharyngeal Nerve (GL) | Final Group Size3 |
|---|---|---|---|
| SHAM | Intact | Intact | N=4 |
| CTx | Transected | Intact | N=5 |
| GLx | Intact | Transected | N=4 |
| CTr + GLr4 | Regenerated to anterior tongue | Regenerated to posterior tongue | N=3 |
| CTr + GLx4 | Regenerated to anterior tongue | Transected | N=4 |
| CTx + GLr (unil) + GLx | Transected | Bilaterally transected, unilaterally regenerated to the posterior tongue | N=4 |
| CT-PostTongue | Regenerated to posterior tongue | Transected | N=4 |
| GL-AntTongue | Transected | Regenerated to anterior tongue | N=5 |
All transections are bilateral unless otherwise noted.
Six rats received a CTx + CTr (unil) + GLx surgery, but only two animals were histologically confirmed so those animals were not included in the paper.
Some animals were discarded due to problems that occurred during testing or because histological analysis indicated inappropriate regeneration or lack of regeneration.
The CTr+GLr group was combined with the CTr+GLx group for statistical analysis to increase power because there was no obvious difference in the postsurgical behavior of these rats.
