ObjectiveTo observe the clinical effect of voice training combined with boxing for mutional falsetto.MethodsA total of 21 patients with mational falsetto were treated with voice training combined with boxing in our department from Jan 2016 to June 2019. All the patients were male with age ranged from 16 to 35 years old and course of disease ranged from one to 20 years. Their clinical manifestions were higher voice pitch or falsetto during or after mutation with obvious noise and occasional hoarseness and cracking voice. Of them, laryngoscopy confirmed poor closure of vocal cords in 19. According to the immediate effect feedback, the voice training combined with boxing was conducted from 1 to 4 times, each voice training lasted 1 to 2 hours. The above process was guided and tracked by the professional voice trainer. Before and after treatment, strobolaryngoscope and voice analysis system were used to record the laryngoscopic findings and vocal acoustic parameters for comparative analysis to evaluate the therapeutic effect.ResultsPre and posttreatment comparisons revealed that fundamental frequency (F0) was significantly lower with significantly improved dysphonia severity index (DSI) and lengthened maximum pronunciation time (MPT) following treatment in all 21 patients. The differences were statistically significant (all P<0.05). The F0 values of 18 patients recovered to normal adult male values. Posttreatment strobolaryngoscopy confirmed good closure of vocal cords in 19 patients with incomplete closure of vocal cords.ConclusionWith remarkable therapeutic effect, voice training combined with boxing has clinical practical value for the treatment of mutional falsetto.
