The aim of our review is to evaluate the safety and efficiency of transoral laser microsurgery (TLM) with potassium-titanyl-phosphate (KTP) laser ablation for 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. KTP is a safe and effective method for treating patients with early glottic neoplasms.
Objectives
To evaluate the safety and clinical effectiveness of transoral laser microsurgery (TLM) with potassium-titanyl-phosphate (KTP) laser ablation for glottic neoplasms.
Data Source
MEDLINE via PubMed, SCOPUS, Web of Science, and Cochrane Library.
Review Methods
A systematic review and meta-analysis of studies assessing the safety and efficacy of KTP laser therapy in patients with early-stage glottic neoplasms.
Results
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.
Conclusion
KTP laser ablation is a safe and effective method for treating patients with early glottic neoplasms. Laryngoscope, 2023
