Abstract：
Supraglottic laryngectomy has evolved from open to transoral endoscopic approaches with advancements in surgical techniques and instruments such as lasers, endoscopes, ultrasonic devices, and robotics. Transoral laser-assisted microsurgery has emerged as an effective treatment option, offering faster functional recovery and serving as an alternative to partial laryngectomy or non-surgical therapies. Traditional endoscopic supraglottic laryngectomy involves resection of both suprahyoid and infrahyoid supraglottic structures. However, in cases where the tumor is limited to the infrahyoid epiglottis, a new technique known as transoral laser-assisted infrahyoid supraglottic laryngectomy allows for tumor removal while preserving the suprahyoid epiglottis, aryepiglottic folds, and vallecula, ensuring optimal preservation of laryngopharyngeal function. This procedure enables patients to swiftly return to their daily routines with minimal complications. This article discusses the surgical technique, potential indications, and advantages and disadvantages of the new approach for infrahyoid epiglottic cancer.
摘要：
声门上喉切除术已从开放式发展到经口内窥镜入路，随着手术技术和诸如激光等器械的进步，内窥镜,超声波装置,和机器人。经口激光辅助显微手术已成为一种有效的治疗选择，提供更快的功能恢复和作为替代部分喉切除术或非手术疗法。传统的内镜声门上喉切除术涉及切除舌骨上和舌骨下声门上结构。然而,如果肿瘤仅限于舌骨下会厌，一种称为经口激光辅助舌骨下声门上喉切除术的新技术可以在保留舌骨上会厌的同时切除肿瘤，会厌褶皱,和Vallecula,确保咽喉功能的最佳保存。该程序使患者能够以最小的并发症迅速恢复他们的日常生活。本文讨论了手术技术，潜在的适应症,舌骨下会厌癌新方法的优缺点。
