喉部分切除术要求达到两个目标 :保存喉的生理功能 ,完全切除肿瘤。喉内窥镜显微外科有时很难达到上述效果 ,而传统的喉部分切除术对于切除喉部小的原位肿瘤显然范围过大。该作者将一种新技术即喉开窗术 (window partial laryngectomy,WPL)应用于 5例声门或声门上癌的患者 ,均 Partial laryngectomy requires two goals: preservation of the larynx’s physiological function and complete removal of the tumor. Laryngeal endoscopic microsurgery is sometimes difficult to achieve the above-mentioned effects, while the traditional partial laryngectomy is obviously too large for resection of a small laryngeal orthotopic tumor. The authors applied a new technique, window partial laryngectomy (WPL), to 5 patients with supraglottic or supraglottic cancer.
