Endoscopic submucosal dissection for a soft-palate lesion with use of a small-bore tracheal tube combined with floss traction

Endoscopic submucosal dissection (ESD) of the middle pharynx is rarely reported, with just one case previously reported by Chen et al. [1]. Several articles have reported that transoral forceps [2] and transnasal endoscopy [3] are convenient for pharyngeal ESD; however, the former method requires two endoscopes, and the ultrathin endoscope has a poor field of view, and small working-channel and scope diameters, which are not conducive to operation.
