Abstract

OBJECTIVE: To explore the effect of Diomed-25 semi-conductive laser in treatment of vocal cord leukoplakia. METHOD: From 1997 to 2001, 30 patients with vocal cord leukoplakia were operated in our hospital by Diomed-25 laser, acoustic analysis were compared and studied before and after operation. All the patients were followed up, ranging from 1 to 5 years. RESULT: There were 16 cases of simple leukoplakia and 14 cases with mild, moderate or severe atypical hyperplasia in this study. None of simple leukoplakia and mild atypical hyperplasia had malignant change, but 2 cases had malignant change who were the cases with moderate and severe atypical hyperplasia respectively. Acoustic analysis showed significant difference between preoperation and postoperation group (P < 0.05). CONCLUSION: The Diomed-25 laser was proved valuable in treating patients with vocal cord leukoplakia.
