Abstract
Transoral surgery assisted by endoscope for locally superficial and early-stage cancers of the head and neck area has been performed. Endoscopic Laryngo-pharyngeal Surgery (ELPS) and Transoral Videolaryngoscopic Surgery (TOVS) have been reported to be safe and useful. We developed a new method called End-flexible-rigidscopic Transoral Surgery (E-TOS) at the Department of Otolaryngology, Head and Neck Surgery, Kyoto Medical Center, and have reported its benefits. The key characteristic is that this surgical procedure uses a flexible-tip rigid endoscope, so we can get a wide working space and choose various types of laryngoscope depending on the tumor location. The author started working at the Department of Otolaryngology, Head and Neck Surgery, Osaka Red Cross Hospital. We report the results of our treatment of 48 oropharyngeal, hypopharyngeal and supraglottic laryngeal cases who underwent E-TOS at our department from July 2013 to March 2016.
