Complications of Endoscopic CO 2 Laser Surgery for Laryngeal Cancer and Concepts of their Management

Endoscopic CO 2 laser surgery (ELS) is a widely accepted treatment modality for early laryngeal cancer. Commonly re- ported advantages of ELS are good oncologic results with low incidence of complications. Although less common if com- pared with open procedures, complications following ELS can be very serious, even with lethal outcome. They can range from intraoperative endotracheal tube fire accidents to early and late postoperative sequels that require intensive medical treatment, blood transfusion, or revision surgery. We present our institutional experience, discuss the possible complica- tions of ELS for laryngeal cancer, and outline the concepts of their treatment, with comprehensive literature review. Com- plications are more frequent following the treatment of supraglottic as compared to glottic cancer. If compared with open surgery, ELS for laryngeal cancer is associated with a lower incidence of complications. Every surgeon performing ELS should comply with particular strategies to avoid complications in the first place, and have a clear concept of their management if they occur
