ABSTRACT
Objective:
To investigate the risk factors for recurrence of benign vocal cord lesions after microsurgery.Methods:
The clinical data of 2 214 patients with benign vocal cord lesions who underwent laryngeal microsurgery at the Department of Otolaryngology-Head and Neck Surgery, Affiliated Hospital of Yangzhou University from April 2013 to April 2022 were collected. The data, including sex, age, drinking history, smoking history, unilateral and bilateral lesions, and diagnosis, were recorded. These patients were divided into six groups according to admission diagnosis polyps, Reinke's edema, leukoplakia, granulomas, cysts, and other benign lesions. All patients were followed up for 0-115 months, with a median follow-up time of 55 months. The Kaplan-Meier curve was used to determine whether there was any difference in the recurrence rate of benign vocal cord lesions among groups after surgical treatment. The Cox regression model was used to analyze the risk factors for the recurrence of benign vocal cord lesions after surgical treatment.Results:
Out of the 2 214 patients, there were 1 953 cases of polyps (88.21%), 41 cases of granulomas (1.85%), 67 cases of cysts (3.03%), 87 cases of leukoplakia (3.93%), 34 cases of Reinke's edema (1.54%), and 32 cases of other benign lesions (1.45%). The recurrence rate for benign vocal cord lesions was 4.86% (95/1 953) in the polyp group, 31.70% (13/41) in the granuloma group, 14.94% (13/87) in the leukoplakia group, 2.98% (2/67) in the cysts group, 8.82% (3/34) in the Reinke's edema group, and 9.37% (3/32) in the other benign lesions group. Univariate analysis showed that bilateral lesions (95% CI 6.899-17.289, P < 0.001), smoking history (95% CI 1.282-2.564, P = 0.001), and alcohol consumption (95% CI 1.173-2.346, P = 0.001) were significantly associated with the recurrence of benign vocal cord lesions. The recurrence rate for benign vocal cord lesions in the leukoplakia group (95% CI 1.375-27.011, P = 0.017) and granuloma group (95% CI 3.053-60.980, P = 0.001) was significantly higher than that in the cysts group. Multivariate analysis of the risk factors for postoperative recurrence of benign vocal cord lesions showed that patients who had bilateral lesions (95% CI 6.680-16.900, P < 0.001) and a history of smoking (95% CI 1.572-16.157, P = 0.007) had a higher risk of recurrence of benign vocal cord lesions compared with those without bilateral lesions and a history of smoking. Granulomas were found to be significantly associated with postoperative recurrence of benign vocal cord lesions (95% CI 4.691-97.667, P < 0.05).Conclusion:
Bilateral lesions and smoking are independent risk factors for the recurrence of benign vocal cord lesions after microsurgery. Granuloma is strongly associated with the postoperative recurrence of benign vocal cord lesions.
