ABSTRACT
Objective:
To analyze the characteristics of vocal fold movement and glottic closure in patients with laryngeal neurogenic injury.Methods:
A total of 185 patients with vocal fold paralysis diagnosed by laryngeal electromyography as neurogenic damage to cricothyroid muscle, thyreoarytenoid muscle and posterior cricoarytenoid muscle were enrolled, they were divided into unilateral vocal fold paralysis group and bilateral vocal fold paralysis group, respectively, and superior laryngeal paralysis group, recurrent laryngeal nerve paralysis group and vagal nerve paralysis group according to nerve injury. The characteristics of vocal fold movement and glottic closure were analyzed under strobe laryngoscope. The qualitative evaluation of vocal fold movement was fixed vocal fold, reduced vocal fold movement and normal vocal fold movement, and the qualitative evaluation of glottic closure was glottic closure and glottic imperfection. The results were analyzed statistically.Results:
The proportion of normal, reduced and fixed vocal fold motion in bilateral vocal fold paralysis group was significantly different from that in unilateral vocal fold paralysis groupï¼P<0.05ï¼, the composition of normal and reduced vocal fold motion in bilateral vocal fold paralysis groupï¼47.70%ï¼ was significantly greater than that in unilateral vocal fold paralysis groupï¼12.27%ï¼. There was no significant difference between the proportion of glottic closure and glottic imperfecta in bilateral vocal fold paralysis group and unilateral vocal fold paralysis groupï¼P<0.05ï¼. The proportion of decreased vocal fold motion in superior laryngeal nerve paralysis groupï¼50.00%ï¼ was higher than that in recurrent laryngeal nerve paralysis groupï¼9.32%ï¼ and vagal nerve paralysis groupï¼9.00%ï¼. The proportion of decreased and fixed vocal fold motion in superior laryngeal nerve paralysis group, recurrent laryngeal nerve paralysis group and vagal nerve paralysis group was statistically significantï¼P<0.05ï¼.There was no significant difference in glottic closure among the three groupsï¼P<0.05ï¼.Conclusion:
Vocal fold movement characteristics of patients with laryngeal neurogenic injury were mainly vocal fold fixation, or normal or weakened vocal fold movement. There may be missed diagnosis of unilateral vocal fold paralysis in clinical practice. In half of the patients with superior laryngeal nerve palsy, vocal fold movement is characterized by vocal fold fixation.Palavras-chave
