Combined transoral-transhyoid endoscopic approach for hypopharyngeal cancer.

Endoscopic transoral surgery for hypopharyngeal cancer is an effective treatment option to avoid invasive open surgery or chemoradiation. Here we describe the case of a 66-year-old patient with cT2N0M0 pyriform sinus cancer whom we treated using a transoral-transhyoid endoscopic approach. Using this approach, a transhyoid route was created in addition to the transoral route and used to extirpate the tumor. En bloc resection of the tumor was completed without difficulty. A combined transoral-transhyoid approach is a useful surgical option for treatment of selected patients with hypopharyngeal cancer. This technique is straightforward to perform and can be used as a backup technique in endoscopic transoral surgery. Also, more complicated lesions can be resected by this approach than by a single-route transoral approach.
