ABSTRACT
Objective:To investigate the clinical effect of voice training on the vocal function of patients with early vocal fold polyps. Methods:From May, 2016 to May, 2018, 80 patients with unilateral wide-based vocal fold polyps were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups underwent voice hygiene education, and the experimental group accepted voice training, 40 minutes a week for twelve weeks in addition. They were evaluated with fiber laryngoscope, voice handicap index (VHI) and the computer phonatory detection before and after training. Results:Five in the control group and seven in the experimental group were dropped out. After training, the cure rate and the improvement rate of vocal fold polyps were significantly higher in the experimental group than in the control group (χ2 = 24.608, P < 0.001). The scores of VHI significantly improved in the experimental group (t/Z > 11.701, P < 0.05), and were better than those in the control group (t/Z > 7.027, P < 0.001). The scores of jitter, shimmer, and maximum phonation time improved (|t/Z| >5.012, P < 0.001) after training in the experimental group, and were better than those in the control group (t/Z > 4.596, P < 0.001). Conclusion:Voice training could improve the vocal function of patients with early vocal fold polyps, reduce hoarseness, and improve the voice quality.
ABSTRACT
Objective To study the voice rest treatment after laryngomicrosurgery in patients with vocal fold polyps .Methods Eighty -five patients with vocal fold polyps were divided into two groups randomly :Group A (48 cases) and Group B ( 37 cases) ,receiving 1 or 2 weeks voice rest postoperation ,respectively .Vocal acoustic analy-sis and fiberlaryngoscopy were performed in all patients before the surgery and 1 ,2 ,3 and 4 weeks after surgery . Results When compared with the preoperative data ,there were no significant differences in jitter ,shimmer and NHR 1 week after surgery in patients of two groups (P>0 .05) .Two weeks after surgery ,all the parameters im-proved significantly in Group B(P<0 .05) ,but only jitter improved in Group A (P<0 .05) .All the data in two groups returned to normal 4 weeks after surgery .Laryngoscopic examination showed varying degrees of vocal fold hyperemia and edema one week after surgery ,which then gradually subsided and gone .At 4 weeks after surgery , the appearance of the operative vocal fold completely returned to normal .Conclusion Patients with vocal fold polyps should be treated with complete voice rest for 2 weeks after surgery ,followed by 2 weeks of relative voice rest .This is beneficial to the voice recovering and the wound healing .
