Oncologic and functional outcomes of transoral CO2 laser cordectomy for early glottic cancer.

OBJECTIVE

To investigate the oncological and functional outcomes of the patients treated with transoral CO2 laser cordectomy for early glottic cancer.

PATIENTS AND

METHODS

Fifty-five consecutive patients who underwent CO2 laser cordectomy for early glottic cancer were retrospectively reviewed.

RESULTS

Overall survival, larynx preservation, and relapse free local control rates were 96%, 100%, and 91%, respectively. Five patients with local recurrences were salvaged with re-cordectomy and/or radiotherapy. In type I cordectomy, VHI-10 consistently improved during postoperative course and VHI-10 at postoperative 12months was significantly better than preoperative value (2.3 vs. 9.4, p=0.02). Perceptual grading, MPT, MFR and AC/DC also improved and were better than preoperative values. In type III cordectomy, shimmer at 12months after cordectomy was significantly better than preoperative value (14.7 vs. 9.3, p=0.007).

CONCLUSIONS

These results further support the rationale of CO2 cordectomy as initial and salvage surgery for early glottic cancer.
