[Effect of denervating duration on the surgical outcome of laryngeal reinnervation in XXXX with unilateral vocal fold paralysis].

@entity1 @entity128
OBJECTIVE: To study the effect of denervating duration on the surgical outcome of laryngeal reinnervation in @entity1 with unilateral vocal fold paralysis (UVFP). METHODS: The charts of 467 consecutive @entity1 with UVFP were reviewed retrospectively. Preoperative and postoperative data, including videostroboscopy, perceptual evaluation of voice (GRBAS scale), acoustic analysis, maximum phonation time (MPT) and laryngeal reinnervation were collected. Multivariable logistic regression analysis was used to identify possible influential factors including the age of @entity1 , gender, degree of @entity128 and duration of @entity128 . Then stratification analysis was performed on the variable-duration of @entity128 , to study how the duration of @entity128 could affect the surgical outcome of laryngeal reinnervation. RESULTS: Multivariable logistic regression analysis showed that the age of @entity1 , degree of @entity128 and duration of @entity128 were significant variables. Stratification analysis on duration of @entity128 demonstrated that in each subgroup postoperative data were significantly improved. When compared among the three subgroups, postoperative data in group with a duration of 6-12 months and group with a duration 12-24 months were significantly better than group with a duration more than 24 months. However, there were no significant differences between group with a duration of 6-12 months and 12-24 months. CONCLUSION: Surgical outcome of laryngeal reinnervation is better in @entity1 those with a duration of @entity128 less than 2 years than in those with a duration of @entity128 more than 2 years.
