Recent development in endoscopic imaging has led to the detection of superficial laryngopharyngeal carcinomas and the effectiveness of endoscopic resection for superficial pharyngeal squamous cell carcinoma have been reported. However, the en bloc and complete resection rates were not sufficient. To identify the precise incision and dissection lines, ensuring a clear operating view is important. Although underwater condition during dissection is useful, saliva, bleeding, and produced floating matter make the operating view worse as the dissection process continues. We presented new method; continuous water perfusion method (CWPM) may contribute to ensuring a clear operating view during dissection of endoscopic resection for superficial pharyngeal squamous cell carcinomas.
