목적: Gaining adequate exposure for salvage nasopharyngectomy is challenging issue because of the limited and difficult access to the nasopharynx. We evaluate the feasibility, safety and functional preservation of transoral robotic nasopharyngectomy via novel approach(lateral palatal flap approach) in locally recurred nasopharyngeal cancer. 방법:From the right side, the relaxing incision was started from the pterygomandibular raphe area, curving it around the maxillary tuberosity and continued forward to the alveolus at the 1st premolar level and the bihalving incision was made. After elevating lateral palatal flap for exposure of the nasopharynx, the resection was performed with da Vinci surgical robotic system transorally. An adequate surgical view was obtainedusing a 30- degree face-up endoscope. The entire posterior nasopharyngeal wall, bilateral Eustachian tubeand Rosenmullerfossacan be visualized. Anteriorly the lower portion of posterior choana could be well visualized. The cancerous lesion was resected en- bloc. After surgery, we evaluated the oncologic result and the functions of swallowing and voice. 결과:The tumor was removed with clear resection margin through an en-bloc resection of right post-sup wall, rosenmuller fossa and Torustubarius. The patient was favorably recovered and had no morbidity from the operation. An oral diet was tolerable 6 days after surgery and the patient was discharged on 9th postoperative day. No recurrent lesion has been noted for 6 months of postoperative period on follow-up nasopharyngoscopy and MRI. There were no other serious difficulties such as velopharyngeal insufficiency, aspiration or delayed swallowing in videopharyngography. The acoustic analysis results showed the normal range of paremeters. 결론:For salvage resection of recurrent nasopharyngeal carcinoma, transoral robotic surgery(TORS)could be a promising option considering advantages such as improved resection and better functional outcomes.
