The effect of surgical resection on the treatment of idiopathic laryngeal contact granuloma

Abstract

Objective:The aim of this study is to investigate the effect of surgical resection of idiopathic laryngeal contact granuloma on the follow-up treatment. Methods:From April 2014 to December 2019, the clinical data of 390 male patients with idiopathic laryngeal granuloma treated were analyzed retrospectively. The patients were divided into the group with history of surgical resection （172 patients） and the group without surgical resection history （218 patients）, and then both received the combined therapy. The treatment efficacy of the two groups were compared. Results:By the end of 6 months after beginning the combined therapy, the total efficacy rate of the patients with a history of surgery was 71.5%（123/172）, and that in patients without a history of surgery was 97.7% （213/218）. The difference between the two groups was statistically significant（Z=-7.828, P=0.0001）. Among the cured patients, the cure time of patients without the surgery history was shorter than patients with surgery history（Z=-4.441, P=0.0001）. Conclusion:Surgical treatment of laryngeal contact granuloma increases the difficulty of follow-up treatment, so surgical treatment is not recommended for newly diagnosed patients with laryngeal contact granuloma.
