Abstract:
ObjectiveThis study aims to explore the therapeutic effect of voice therapy combined with neuromuscular electrical stimulation （voice-physical therapy） on patients with postoperative vocal cord paralysis. MethodsTotally 42 patients diagnosed with postoperative vocal cord paralysis from November 1， 2018 to December 31， 2019 in our center were included in this study. These patients were divided into different sub-groups according to their age， sex， surgical procedure， preservation of recurrent laryngeal nerve and intervention timing. Voice handicap index （VHI）， maximum phonation time （MPT） and vocal cord mobility were investigated before and after one-month voice-physical therapy. T-test was used to evaluate the variation of these factors， with SPSS 22.0. The correlation between the effect of this therapy and age， gender， surgical procedure， preservation of recurrent laryngeal nerve and intervention timing was further investigated with subgroup analyses. ResultsVoice-physical therapy could significantly reduce the scores of functional （11.78±3.06， P<0.001） ， physical （9.9±2.8， P<0.001） and emotional sections （9.7±3.13， P<0.001） in the VHI scale. It could also prolong the MPT （5.62±3.88， P<0.001）， and significantly improve vocal cord closure （Z =5.62， P<0.001）. No significant differences of therapeutic effect were found among different subgroups of age， gender， surgical procedure， preservation of recurrent laryngeal nerve and intervention timing. ConclusionsVoice-physical therapy promotes the recovery of postoperative vocal cord paralysis. This effect exists regardless of different intervention timing， age， gender， surgical procedures and status of preservation of recurrent laryngeal nerve.
