〔Abstract〕 Objective To analyze the value of Microsupport laryngoscopy in the treatment of vocal cord polyps and vocal cord nodules. Methods 30 patients with vocal cord polyps and vocal cord nodules treated in Dongguan Chashan Hospital from July 2018 to may 2019 were selected as the research objects. They were divided into control group with 16 cases and observation group with 14 cases. The control group underwent removal under electronic laryngoscope and the observation group underwent removal under micro-support laryngoscope. The clinical efficacy, various voice indexes (fundamental frequency perturbation, amplitude perturbation, standardized noise energy) and the improvement of quality of life before and after treatment were compared between the two groups. Results The clinical efficacy of the observation group was 92.8%, which was higher than 62.5% of the control group (P < 0.05). After treatment, the fundamental frequency perturbation and amplitude perturbation in the observation group were lower than those in the control group, and the standardized noise energy was higher than that in the control group (P < 0.05). After treatment, the scores of quality of life in the observation group were higher than those in the control group (P < 0.05). Conclusion Microsupport laryngectomy is effective in the treatment of vocal cord polyps and vocal cord nodules, and can effectively protect the postoperative recovery of vocal cord function.
