After operation, the control group received routine treatment, and the study group received voice training on the basis of routine treatment. The results of voice acoustic analysis in the two groups were compared at 8 weeks after operation.RESULTS After 8 weeks, the maximum phonation time(MPT), dysphonia severity index (DSI) and the highest frequency(F0-High) of the study group were significantly higher than that of control group (P0.05).CONCLUSION Voice training in the early postoperative period of vocal cord polyps was helpful to the recovery of the voice.
