ENDOSCOPIC APPROACH FOR LARYNGEAL AND HYPOPHARYNGEAL MALIGNANCIES WITH THE WEERDA DIVERTICULOSCOPE

Abstract

Introduction: The aim of the present work is to present our preliminary results for the use of the Weerda distending diverticuloscope (W DD) for diagnostic and surgical interventions in patients with upper airways and digestive system disorders, especially of malignant origin.Material and methods: For the 2-years period 2008-2009 the W DD was used in 21 patients. Under general anesthesia and protection of the front teeth the W DD is introduced, following the course of the endotracheal tubus. By adjusting the blades of the instrument very good exposition of the whole larynx and partially of the hypopharynx are achieved.Results: In 15 of the 21 cases the W DD allowed for optimal visualization of the region of interest. In 12/15 patients exploratory examinations with biopsies were performed. In 2/15 cases complete resection of carcinoma of the posterior pharyngeal wall was performed. In 1/15 cases arytenoidecomy was performed. In 6/21 cases we were unable to introduce the instrument because of anatomical factors.Conclusion: The W DD presents a versatile tool for better exposing the laryngeal and hypopharyngeal regions. It is a valuable complement to the standard surgical armament of the ENT H&N surgeon, which gives new promissing diagnostic and treatment options.
