Abstract
To evaluate the safety and clinical effectiveness of transoral laser microsurgery (TLM) with potassium-titanyl-phosphate (KTP) laser ablation for glottic neoplasms. MEDLINE via PubMed, SCOPUS, Web of Science, and Cochrane Library. A systematic review and meta-analysis of studies assessing the safety and efficacy of KTP laser therapy in patients with early-stage glottic neoplasms. Eight studies were included. After an average follow-up of 3.3 years, the overall survival and disease-free survival for patients who underwent KTP were 90.7% (95% CI 85%-96.5%) and 98.5% (95% CI 97.3%-99.8%), respectively. In the single-arm meta-analysis, the pooled estimate of recurrence was 7.7% (95% CI 3.4%-12%). The overall voice handicap index (VHI) estimate attributed to KTP in the single-arm meta-analysis was 6.76 (95% CI [3.05, 10.48]) and 5.21 (95% CI [2.86, 7.56]) within 6 months and after a one-year follow-up, respectively. KTP laser ablation is a safe and effective method for treating patients with early glottic neoplasms. Laryngoscope, 133:1806-1814, 2023.
