Abstract
OBJECTIVE: To evaluate the clinical efficacy of high-frequency electrocautery under electronic laryngoscopy combined with acid-suppressing drugs (Proton Pump Inhibitor, PPI) in the treatment of Refractory Laryngeal Contact Granuloma (RLCG). METHODS: A total of 42 patients with RLCG, treated at our hospital from January 2019 to January 2024 were included in this study. The patients underwent high-frequency electrocautery to excise laryngeal granulomas under local anesthesia using electronic laryngoscopy, followed by PPI therapy. Follow-up started one-month post-surgery and lasted for 6-12 months (average of 8.5 months), to assess the cure rate and overall efficacy. RESULTS: The cure rate was 76.19%, and the overall efficacy rate was 92.86%. On average, each patient underwent 1.79 procedures. The combined treatment of high-frequency electrocautery under local anesthesia with electronic laryngoscopy and PPI therapy demonstrated significant therapeutic effects for RLCG. The treatment was simple, well-tolerated by patients, cost-effective, and resulted in rapid symptom improvement, all without the need for general anesthesia or intubation. CONCLUSION: The combined approach of high-frequency electrocautery under local anesthesia with electronic laryngoscopy and PPI therapy is effective in treating refractory laryngeal contact granuloma. This method offers the advantages of a straightforward surgical procedures, high patient tolerance, low cost, quick symptom relief, and no requirement for general anesthesia or intubation.
