[Influence of voice training combined with active breathing and circulation technique on voice recovery after vocal cord polyp surgery].

To explore the influence of voice training combined with active breathing and circulation techniques on voice recovery following vocal cord polyp surgery. A total of 110 patients who underwent vocal cord polyp surgery at our hospital from May 2022 to November 2023 were selected and randomly divided into a control group （=55） and a combination group （=55） using a random number table method. During the recovery period, both groups received dietary control and aerosol treatment. The control group participated in voice training, while the combination group received active breathing and circulation techniques in addition to voice training for 2 months. Morphological changes, voice acoustic indicators （Shimmer, Jitter, Maximum Phonation Time[MPT]）, and the Voice Handicap Index （VHI） were compared between the two groups, and clinical efficacy was evaluated. The combination group demonstrated higher clinical efficacy after training compared to the control group, with a statistically significant difference （<0.05）. The proportion of incomplete closure, abnormal mucosal wave, and supraglottic compensation decreased in both groups after training （<0.05）. However, there was no significant difference in the proportions of incomplete closure and abnormal mucosal wave between the two groups （>0.05）. Notably, the proportion of patients with supraglottic compensation in the combination group was lower than in the control group （<0.05）. After training, the Shimmer and Jitter values decreased in both groups, with the combination group exhibiting lower values （<0.05）. Conversely, the MPT values increased in both groups, again with higher values in the combination group （<0.05）. Additionally, after training, the functional, physiological, and emotional scores of the VHI decreased in both groups, with the scores in the combination group lower than those in the control group, demonstrating statistical significance （<0.05）. Voice training combined with active breathing and circulation techniques has a beneficial effect on recovery following vocal cord polyp surgery. This combined approach significantly improves vocal cord morphology and acoustic indices, alleviates voice disorders, and enhances overall voice recovery.
