[Clinical effect of nasal endoscope combined with supporting laryngoscope surgery in the treatment of polyps of vocal cord and its influence on voice function of patients].

To explore the clinical value of nasal endoscope combined with supporting laryngoscope surgery in the treatment of polyps of vocal cord. Ninety-four patients with vocal cord polyps were randomly divided into the control group (47 cases) and the observation group (47 cases). The patients in the control group were treated with simply supporting laryngoscope surgery while the patients in the observation group were treated with nasal endoscope combined with supporting laryngoscope. The therapeutic effects, voice function changes before and after operation, complications and recurrence of the two groups were observed. The total effective rate was 93.62% in the observation group, compared to 78.72% in the control group, the difference was statistically significant (<0.05). The incidence of postoperative complications in the observation group was 8.51%, compared with 25.53% in the control group, the difference was statistically significant (<0.05). Six months after operation, there was no recurrence in the observation group, but the recurrence rate in the control group was 4.26%. There was no significant difference between the two groups (>0.05). 12 months after operation, the recurrence rate of the observation group was 2.13%, compared with 14.89% of the control group, the difference was statistically significant (<0.05). Nasal endoscope combined with supporting laryngoscope for vocal cord polyps has a definite effect and can significantly improve the voice function of patients with high safety and low recurrence rate, which is worthy of promotion..
