Latency of the swallowing reflex before and 3 months after treatment. Asterisks indicate significant differences between before and after treatment. The error bars indicate standard deviation. a Comparison of the latency time of the swallowing reflex before and 3 months after treatment (n = 53, p < 0.05, paired t-test). b Comparison of the percentage of patients with a delayed swallowing reflex before and 3 months after treatment (p < 0.01, Fisher’s exact test). Time over 3 s was defined as a delayed swallowing reflex
