Study phase:

N/A

研究设计:

单臂 

Study design:

Single arm 

研究目的:

1. 以二氧化碳(CO?)激光在口腔黏膜均质型白斑病治疗中的应用为核心,通过单臂研究,系统评估CO?激光治疗该疾病的临床疗效与安全性;观察CO?激光在治疗有效率、复发率等核心临床指标上的差异; 2. 明确CO?激光治疗口腔黏膜均质型白斑病的优势与局限,推动OLK治疗技术的优化升级,为临床中OLK治疗方案的选择提供科学、重要的参考依据。  

Objectives of Study:

1. Focusing on the application of carbon dioxide (CO?) laser in the treatment of homogeneous oral leukoplakia, this study will systematically evaluate the clinical efficacy and safety of CO? laser therapy via a single-arm design, and compare its performance on core clinical indicators including treatment response rate and recurrence rate. 2. This project aims to clarify the advantages and limitations of CO? laser in the treatment of homogeneous oral leukoplakia, promote the optimization and upgrading of OLK treatment technologies, and provide a scientific and important reference for the clinical selection of OLK management strategies.
