 Endoscopic observation of the laryngopharynx is technically challenging due to the gag reflex and the complicated anatomical structure. However, it is possible to determine the size and depth of tumoral invasion using image-enhanced endoscopic techniques such as narrow band imaging and carefully magnified visualization after vocalization with conscious sedation. Further visualization of the larynx under general anesthesia may be important to assess the extent of disease using iodine staining. In this study, we describe endoscopic diagnosis of superficial pharyngeal cancer in three cases treated at our hospital.
