Objective To explore the effects of cervical sympathetic block ( CSB ) on facial nerve regeneration in rats and seek the optimal timing of treatment.Methods A total of 72 adult Sprague-Dawley rats were divided randomly into 4 groups of sham-operation (sham), model control (NS), CSB1 and CSB2 ( n=18 each).Except for sham group , the model of peripheral facial paralysis was established for three other groups.After treating facial nerves injury with CSB at different timepoints , the behavioral changes of rats were observed.Electroneurography ( ENoG) of injured nerves was performed and the expressions of glial cell derived neurotrophic factor ( GDNF) of facial nerve nucleus were detected at different stages.Results The facial whisker movement function scores in sham , NS, CSB1 and CSB2 groups were 3.87 ±0.35, 0.50 ± 0.52, 1.07 ±0.62 and 0.81 ±0.42 ( F =2.934, P=0.035) at Day 7, 3.85 ±0.37, 0.91 ±0.52, 1.57 ±0.65 and 1.07 ±0.62 ( F=2.537, P=0.038) at Day 14 and 3.85 ±0.37, 1.71 ±0.47, 3.00 ± 0.68 and 2.36 ±0.49 (F=3.627, P=0.024) at Day 28.At Day 7, LatSD and AmpSD were not detected in NS, CSB1 and CSB2 groups.However, at Day 14, the values of LatSD were (1.26 ±0.19), (6.67 ± 0.36), (4.67 ±0.36) and (6.17 ±0.36) ms, showing a significant difference (F=3.052, P=0.024) and AmpSD (6.42 ±1.93), (2.16 ±1.87), (4.16 ±1.80) and (3.66 ±1.40) mv, also a significance (F=3.634, P=0.021).And at Day 28, LatSD were (1.31 ±0.17), (3.17 ±0.19), (1.93 ±0.12) and (2.60 ±0.22) ms (F=2.729, P=0.032) and AmpSD (6.82 ±2.30), (4.72 ±5.23), (6.22 ± 3.50) and (5.82 ±4.10) mv (F=3.827, P=0.019).The expression quantities of GDNF in 4 groups produced significant differences at Day 7 (4.67 ±0.81, 13.52 ±0.58, 26.17 ±1.01 and 14.86 ±1.03, F=3.637, P=0.028), Day 14 (5.67 ±0.57, 24.41 ±2.86, 26.52 ±1.36 and 25.48 ±1.42, F=2.946, P=0.031) and Day 28 (5.37 ±0.92, 26.64 ±1.68, 27.38 ±1.66 and 25.69 ±1.99, F =4.273, P =0.012 ).Conclusion During early stage of facial nerve injury , the treatment of CSB may increase the expression of GDNF of facial nerve nucleus at early stage and thus accelerate the recovery of facial nerve injury in rats.
