Functional outcomes after CO2 laser treatment of early glottic carcinoma

OBJECTIVES: To analyze vocal outcome after endoscopic CO2 laser treatment of early glottic carcinoma by perceptive and objective assessment. STUDY DESIGN: Retrospective study. METHODS: Retrospective analysis of 141 consecutive patients undergoing surgery for previously untreated early glottic carcinoma between October 1993 and July 2003. Five types of laser cordectomies as classified by the European Laryngological Society classification were performed. Comparison of voice results between the different types of cordectomies as well as with a control group was performed. RESULTS: There was no significant difference in the vocal parameters between subepithelial and subligamental cordectomies and controls (P > .05). There was, however, a significant difference between the groups of transmuscular, total, and extended cordectomies and controls (P < .05). CONCLUSIONS: Good oncologic results and vocal outcomes with no difference between controls and subepithelial and subligamental cordectomies support the use of CO2 laser endoscopic surgery as the first line of treatment for early glottic cancer.

CO2-laser treatment of recurrent glottic carcinoma

The records of 23 patients treated by CO₂-laser surgery for recurrent glottic carcinoma after radiotherapy were studied retrospectively to assess treatment results and complications. 15 patients (65%) were cured with one or more laser procedures. The remaining 8 underwent a total laryngectomy for a second or third recurrence. One patient (4%) died of disease. No major complications from C0₂-laser surgery were encountered. It is concluded that C0₂-laser surgery is a safe method of treatment of recurrent glottic carcinoma.     

Treatment of early glottic carcinoma with transoral laser CO2

OBJECTIVE: We present our outcome in the treatment of 125 patients with malignant glottic lesions between 1992 and 2003 in a retrospective study. PATIENT AND METHODS: We analyze 125 cases of patients, with previously untreated carcinoma of the larynx with histological diagnosis, treated with Transoral Laser Microresection. We will pay special attention to those tumors involving the Anterior Commissure. We will also analyze several parameters related to the post and intraoperatory histopathological report, in order to decide adjuvant therapies. We will also analyze the technique indications, complications, hospital length of stay, oncologic and functional outcomes, survival and follow up of recurrences. OUTCOMES AND CONCLUSION: Transoral laser microresection is an effective and functional preserving procedure, and nowadays the base of the treatment of early glottic carcinoma. Anterior Commissure involvement is a prognostic factor. Sometimes complementary therapies are needed based on by the histopathological report.     

Our experience in CO2 laser surgery for early glottic carcinoma

In the years 1990-2002 187 patients were treated laser microsurgery due to T1, T2 laryngeal cancer. One of the purposes of this work was analysis of resurgery cases due to recurrence of neoplasmatic process after laser cordectomy, therefore a group of 93 patients, treated in the years 1990-1997 was controlled. The local recurrence of neoplasmatic process was observed in 13 persons. The changes were once more removed in laser microsurgery in 5 patients. In 8 persons total laryngectomy was performed with subsequent radiological treatment. The best results of treatment were observed in patients in whom changes were limited to medial part of vocal cord while recurrences were the most often in patients with anterior commissure lesion. In case of recurrences after laser microsurgery all other kinds of possible treatment can be applied as, partial conventional surgery, total laryngectomy, X-ray therapy or repeated laser microsurgery. Functional evaluation of voice in 64 patients, who due to early stage of carcinoma were submitted unilateral CO2 laser cordectomy, was performed. The appearance and mobility of larynx were registered and evaluated in particular periods post surgery, the patients voices were registered and acoustic analysis submitted. Gradual voice improvement following the wound healing were observed in subjective patients evaluation as in objective one. In many cases very good functional results were obtained, which made possible for patients after CO2 laser cordectomy to continue work requiring good function of larynx. In 43 patients the psychological aspect of laser microsurgery influence was analyzed by use of anonymous questionnaires. It proofed, that in the majority of cases, the laser surgery had no influence for the social and company life of people submitted laser cordectomy. In 7 patients the views of larynx were very specific on the free edge of scar after removed vocal cord--spherical structure of 3-5 mm diameter has appeared in 2 to 6 months after laser cordectomy. In pathological examination--laryngitis chronica, granulatio--was stated. In further observation of patients no recurrences were observed. The described changes resemble granulomas and the most probably are caused by laser ray. Higher power lasers are useful, even when used at the same wattage as older models as they produce less carbonization of tissue during use.
