[Evaluate the effect of Diomed-25 laser in treatment of early vocal cord carcinoma].
OBJECTIVE
To observe the effect of Diomed-25 laser in treatment of early vocal cord carcinoma.


METHODS
Eighteen cases of early vocal cord carcinoma were treated by laser surgery. Among the cases, 7 were under local anesthesia, and 10 were under general anesthesia, 1 case was operated laryngofissure due to failure of tumor exposure.


RESULTS
The follow up period was from 3 to 5 years. Relapse were detected in 3 out of 18 cases of early vocal cord carcinoma after Diomed laser surgery under fiber or self-retaining laryngoscope. Of the recurrent cases, 2 T1b tumors offended the anterior commissure, another was T2 case, 1 failed to be followed-up (taken into dead), 3 year survival rate was 100.0% (18/18), 5 year survival rate was 90.9% (10/11). Except 2 cases receiving total laryngectomy, the others had their laryngeal function reserved.


CONCLUSIONS
It has clinical value to use Diomed-25 laser in treatment of early vocal cord carcinoma, and its advantages include lower complication rate and laryngeal function well retained.
