[Clinical observation of radiofrequency coblation therapy in early glottis cancer involving the anterior commissure with endoscope].

Objective: To explore clinical effect of CO₂ laser combined with radiofrequency coblation therapy on early glottis carcinoma involving the anterior commissure with endoscope. Method: The clinical data of 10 patients with early glottis cancer involving the anterior commissure who were underwent CO₂ laser and radiofrequency coblation with angled endoscope was retrospective analyzed.All patients receieved CT scan with contrast to rule out the cases with thyroid cartilage plate involvement. Result: The surgeries were performed successfully on all of the 10 patients. The pathology of the 10 patients were all squamous cell carcinoma. Surgical margins showed no residual tumor cell. There was no recurrence or metastasis with a follow-up of 6 to 48 months. Conclusion: It was an effective treatment for the CO₂ laser and radiofrequency coblation therapy in glottis cancer involving the anterior commissure with endoscope.
