Abstract

Background and Objectives：For the treatment of early glottic cancer, not only complete excision of tumor, but also preservationof laryngeal function is important. Several methods such as open partial laryngectomy, transoral endoscopic CO2 laserpartial laryngectomy, radiation therapy are possible. This study was performed to investigate the utility of laser cordectomy andits oncologic and functional outcomes. Subjects and Method：A retrospective analysis was performed for patients of 31 casesof early glottic cancer who were treated with transoral CO2 laser cordectomy at the Hanyang University Hospital from November1997 to Decemcer 2004. We analyzed oncologic and functional outcomes with the review of medical records. Results：Among31 cases of early glottic cancer, 30 cases were male and 1 case was female. The mean age was 61.4 years (45-77 years), andthe mean follow up period was 34 months (13-97 months). Histopathologically, one case was verrucous carcinoma and theothers were squamous cell carcinoma. According to T stage, 31 cases were classified into 3 Tis, 22 T1a, 4 T1b, and 2 T2. Localrecurrence occurred in 2 cases. One patient was in disease free state after salvage total laryngectomy and 1 patient was alive withdisease state because he denied further treatment. The major complications such as aspiration, respiratory distress were notfound in any of 31 cases. Minor complications such as anterior web, polyp, granulation tissue were found in 8 cases (25.8%).Conclusion：Transoral CO2 laser cordectomy might be the effective treatment modalitiy in early glottic carcinoma becauseof high local control rate, excellent functional outcomes and low complication rate.
