: Nasopharyngeal foreign bodies (FBs), which are generally caused by a strong, external force, are seldomly encountered. Removing these FBs is challenging for otorhinolaryngological surgeons because of the vital structures surrounding the nasopharynx, such as the skull base, cranial nerves, and internal carotid artery. Here, the authors report the case of a 69-year-old man referred to our hospital after accidentally cutting his face while using a grinder. Grinder fragments were deeply embedded in the face, thus becoming nasopharyngeal FBs. The authors evaluated three-dimensional volume rendering images and immediately removed these FBs using an endoscopic endonasal transseptal approach under general anesthesia. The postoperative course was uneventful. Using the endoscopic endonasal transseptal approach after evaluating preoperative three-dimensional volume rendering images may help eliminate nasopharyngeal FBs safely.

Surgical resection is one of the salvage treatment options for local recurrence or residual nasopharyngeal cancer and secondary cancer in the nasopharynx. Because of the anatomical complexity of the nasopharynx, the approach is limited and it is also difficult to secure a sufficient margin. We report a case of radiation-induced sarcoma that occurred 14 years after chemoradiotherapy as the initial treatment for nasopharyngeal cancer. The tumor, which arose from the superior and posterior wall of the nasopharynx, was resected via the transpalatal approach with mandibular swing combined with nasal endoscopy. By inserting instruments from two insertion paths, we obtained a good field of view and operability.Previous reports about salvage surgery for nasopharyngeal malignant tumors have been limited in Japan; this procedure is considered to be a useful approach to the nasopharynx.
