Abstract

Today, head and neck superficial cancer can be diagnosed thanks to improvements in new endoscopic systems such as narrow band imaging (NBI). We treat these superficial cancers by transoral mucosal resection with direct laryngoscope under microscopic view. This method requires adequate view and enough working space to maintain a satisfactory operation field, so it is important to choose an appropriate direct laryngoscope. We investigated the types of direct laryngoscope used in transoral mucosal resections for oropharyngeal and hypopharyngeal superficial cancers. A large-caliber direct laryngoscope enabled us to resect oropharyngeal and hypopharyngeal superficial cancers located at the posterior wall especially, with wide view and satisfactory operability.
