Device for paratracheal dissection for a total pharyngolaryngoesophagectomy

Abstract

In a paratracheal dissection for a total pharyngolaryngoesophagectomy, it is important to prevent trachea cartilage necrosis, which becomes a trigger for serious complications and for keeping sufficient blood supplied around the trachea. We tried to keep one of four right and left affiliates of the bloodstream from either the superior thyroid artery or the inferior thyroid artery. This was achieved by a method of safely minimizing the creation of the tracheostoma. Moreover, this method was thought to be useful for the management of the tracheostoma and to prevent postoperative complications and stricture, which contributes to the improvement of QOL after a permanent tracheostomy.
