이상의 성적에서 레이저 성대 절제술은 초기 성문암종에 대한 일차 치료법으로 유용하다고 생각되었으며, 일차 절제가 가장 중요하고 그후 성대를 포함한 전체 후두점막에 대하여 주기적으로 현수후두경하에 수술현미경을 이용한 추적관찰과 원격전이 및 이차암의 발생 유무에 대하여 적극적인 추적검사가 필요할 것으로 사료된다.
Early detection of glottic cancer, facilitated by rigid telescopes or flexible fiberoptic laryngoscope in addition to sparse true vocal cord lymphatics, makes this a highly curable tumor in its early stage. Early glottic cancer has a high cure rate with only radiotherapy or conservative surgery. However complications such as mucositis with radiotherapy and voice complications with conservative surgery has raised recent interest in endolaryngeal laser cordectomy. Laser cordectomy can preserve phonatory function and avoid the complications such as mucositis of radiotherapy. To determine the effectiveness of laser cordectomy, the authors made a two year retrospective study of 23 early glottic cancer cases. Fourteen cases(60.9%) who underwent 1 to 3 endoscopic laser cordectomy with KTP-532 laser were cured with this procedure alone. Seven cases needed an additional radiotherapy and three cases needed therapy with salvage operation. We conclude that the endoscopic laser surgery is a good strategy for the properly selected glottic cancer.
