**Abstract**

Premalignant conditions of larynx encompass a variety of lesions that have the potential to evolve into malignant changes. The dysplastic premalignant epithelial changes of larynx have significantly increased Risk of developing in cancer than the hyperplastic stage of epithelial changes and this transformation significantly depends on the grade of dysplasia. Therefore, early diagnosis & prompt treatment should thus prevent the development of invasive carcinoma requiring more debilitating surgical resection. The histopathological examination is diagnostic & the evolution of advanced laryngoscopic surgical procedures including CO2 laser and newer treatment methods such as photodynamic therapy has shown promising results in their management.
