Abstract

Transoral surgery assisted by endoscope for superficial cancer and early-stage cancer of the head and neck area has been performed. The safety and usefulness of Endoscopic Laryngo-pharyngeal Surgery (ELPS) and Transoral Videolaryngoscopic Surgery (TOVS) have been reported. We developed a new Endoscopic Transoral Surgery method used a flexible-tip rigid endoscope and have used it. The key point is that this surgical procedure uses a flexible-tip rigid endoscope, so we can choose various types of laryngoscope to match the tumor location. We report a study of 29 laryngeal/ oropharyngeal/hyopharyngeal cases who underwent E-TOS at our institution from March 2010 to December 2012. The age of patients was 45-86 (mean: 65) years old, and the male-to-female ratio was 25:4. The observation period was 20-983 (median: 262) days. Four cases were superficial cancers, 24 cases were invasive cancers, and one case was MALT lymphoma. 24 cases were fresh cases, 3 cases were recurrence after irradiation, and two cases were recurrence after resection by the cervical approach at another hospital. We carried out curative treatment for 28 cases. We were able to perform en-bloc resection for 25 cases (89%) and curative resection for 26 cases (93%), which was equivalent to TOVS. Using this procedure, we can perform wide and safe resection of almost the whole area of the larynx, oropharynx and hypopharynx, so it is a possible choice for minimally invasive and transoral surgery.
