The degrees of numbness included 4 degrees: severe, moderate, slight, and none. Severe = 7 to 10 scores; moderate = 3 to 6 scores; slight = 1 to 2 scores; none = 0 score. Baseline: before the operation; 1 min: 1 min after alcohol given. 2 h, 24 h, 1-month, and 3-month represented the following time points: 2 h, 24 h, 1-month, and 3-month after the operation.
