Anteroposterior length difference | 2.5 (−4–5) | .28 | 10.5 (−1–17) | <.001 |
Anteroinferior margin difference | 0 (0–0) | 13.5 (10–16) | <.001 | |

↵a Preoperative and postoperative morphologic features of the transferred SMGs, presented as averaged length and location differences between the SMGs in each patient (transferred gland–contralateral gland) followed by ranges of the differences. Positive values indicate anterior and superior directions, respectively. P values for significance of length differences are derived from paired pre- and post-t tests with a reference value of 0 mm (no difference).
