INTRODUCTION: Transoral laser microsurgery (TLM) has won territory in larynx oncology, establishing itself as an effective option in treatment of glottic, supraglottic, and hypopharynx tumors. Its advantages include limited resections, a reduction in number of tracheostomies, and the use of nasogastric tubes. Moreover, its oncological benefits are similar to those from open surgery in patients with early or advanced stages, when correctly selected. OBJECTIVE: The objective of this study is to review oncologic outcomes obtained with the treatment of a series of glottic tumors, treated by TLM...

Introduction Transoral laser microsurgery (TLM) has established itself as an effective option in the management of malignant tumors of the glottis, supraglottis, and hypopharynx. Nonetheless, TLM is not a harmless technique. Complications such as bleeding, dyspnea, or ignition of the air may appear in this type of surgery. Objective The aim of this study is to describe the complications that occurred in a group of patients treated for glottic and supraglottic carcinomas in all stages by TLM. Methods This study is a retrospective analysis of patients diagnosed with squamous cell carcinoma of the glottis and supraglottis for all stages (T1, T2, T3, T4), N -/ + , M -/+ treated with TLM between January 2009 and March 2012 in a tertiary hospital...

OBJECTIVES/HYPOTHESIS: Transoral laser microsurgery (TLM) for hypopharyngeal cancer results in a lower incidence of complications than conventional open surgery. However, additional knowledge regarding the histoanatomical characteristics of the hypopharynx is necessary to prevent severe complications during TLM. The purpose of this study is to investigate the histoanatomical characteristics of the hypopharynx for TLM. STUDY DESIGN: Histoanatomical study. METHODS: Whole organ serial sections of three hypopharynges and larynges from autopsy cases were subjected to hematoxylin & eosin and Elastica van Gieson staining...

Over the past 5 years, transoral robotic surgery (TORS) has become well established as one of the standard treatment options for T1 and T2 oropharyngeal squamous cell carcinoma. Besides this main indication, TORS can provide with improved access to other subsites of the upper aerodigestive tract as well, such as the supraglottic larynx and the hypopharynx, with superior visibility and maneuverability to that of transoral laser microsurgery (TOLM). Since September 2011, over one hundred TORS procedures have been performed at our institution, predominantly for oropharyngeal cancer...

INTRODUCTION: Within the last years transoral robotic surgery (TORS) with endoscopic visualization and surgery has gained importance in the resection of head and neck tumors and is an alternative to transoral laser microsurgery. The further development of transoral endoscopic systems should enhance the surgical options and reduce the surgery related morbidity. Thus, we evaluated a new flexible endoscopy system in cadaver -dissections. METHODS: In March 2014 we performed all standard procedures of transoral tumor surgery in the oropharynx, hypopharynx and larynx in 3 fresh cadaveric specimens using the Medrobotics Flex(®) System...

The management of Zenker's diverticulum remains controversial, as both external and endoscopic procedures are potentially associated with post-operative complications and risks. The endoscopic approach is based on cricopharyngeal myotomy or myectomy by laser, cautery or stapling. A retrospective chart review has been made from December 1994 to April 2009 of all patients with Zenker's diverticulum treated by endoscopic cricopharyngeal myectomy using CO(2) laser at the Department of Otorhinolaryngology - Head and Neck Surgery of the University of Brescia, Italy...

Histological affected or close margin is an adverse factor in conventional surgery of larynx-hypopharynx cancer. Our objective was to analyze the relevance of the margins in transoral laser microsurgery (TLM). A retrospective study of 357 consecutive patients with cancer of the larynx and hypopharynx (T1-T4) treated with TLM. Three possible margins were considered: tumor free, affected, and uncertain. An affected margin showed marked tumor infiltration. An uncertain margin was defined when the sample was insufficient, when it showed carbonization impeding accurate evaluation, or when tumor cells were less than 2 mm...
