Although in recent years there have been a tendency to choose partial hypopharyngectomy with laryngeal preservation in some cases of early stage hypopharyngeal cancer, the standard operation for advanced stage is still considered to consist primarily of total pharyngolaryngectomy. In this article, we report a case of an advanced T3 hypopharyngeal cancer with laryngeal preservation. The field of resection ranged from most of the piriform sinus to the epiglottis, aryepiglottic fold, paraglottic space, false vocal cord, and a part of the arytenoids. Although the resected area encompassed such a large area as described above, we succeeded in the reconstruction with several devices and attained good swallowing function by making the bulky rectus abdominal myocutaneous flap over-hang the supraglottic space and occupying the piriform sinus of the affected side with it. In conclusion, we believe that there is a possibility to perform partial hypopharyngectomy with laryngeal preservation even in T3 cases when movement of bilateral arytenoids and vocal cords are both intact.
