Conservative Treatment versus Surgery for Laryngeal Contact Granuloma: A Prospective Study

Aims: To confirm the efficacy of conservative treatment for laryngeal contact granuloma and identify factors influencing treatment outcome. Methods: In this prospective study, patients with laryngeal contact granuloma were divided into a group receiving conservative treatment and a group undergoing surgery. Efficacy was assessed by analyzing the complete response after a 48-week follow-up. The association of treatment outcome with clinical factors was then evaluated. Results: In total, 61 patients, 43 in the group receiving conservative treatment and 18 in the group undergoing surgery, were analyzed, and the complete response rate was 72.1% and 38.9%, respectively. Both univariate analysis and multivariate analysis revealed that treatment modality (p₁ = 0.015, p₂ = 0.043), voice abuse (p₁ = 0.010, p₂ = 0.010), and the size of the granuloma (p₁ = 0.031, p₂ = 0.020) were significantly associated with the complete response of laryngeal contact granuloma. Kaplan-Meier curves showed that alcohol consumption (p = 0.031), voice abuse (p #x3c; 0.001), and granuloma size (p = 0.025) were significantly related to the complete response of conservative treatment. Conclusions: This prospective study strengthens the argument for conservative treatment (instead of surgery) as the first choice for laryngeal contact granuloma. The results also suggest that voice abuse, alcohol consumption, and the size of the granuloma may predict treatment outcome.
