Base on 37-All-MPM, DTI index analysis of the healthy/affected facial nerves of 19 patients and the healthy nerves (mean ± SD).

| MD | 1.005 ± 0.152 (N1 = 19) | 1.097 ± 0.214 (N3 = 36) | 0.092 (t = − 1.714) |

MD—the unit is 10−3 mm2/s. N1 refers to the number of nerves on the healthy side of the patient. N2 refers to the number of nerves on the affected side of the patient. N3 refers to the number of nerves on both sides of healthy people. N4 refers to the number of nerves on both sides of healthy people plus the number of nerves on the healthy side of patients.
