Nasopharyngeal Endoscopic Submucosal Dissection (NESD) for Stage I Nasopharyngeal Carcinoma.

This study introduces nasopharyngeal endoscopic submucosal dissection (NESD), a new, standardized surgical technique for treating early-stage nasopharyngeal carcinoma by removing the entire nasopharyngeal mucosa and preserving key anatomical structures. NESD was successfully performed in the stage I nasopharyngeal carcinoma patient with minimal blood loss and no complications, showing promising results for safety and efficacy over a 2-year follow-up.
