Short-Term Efficacy of the Transnasal-Transoral Approach to Endoscopic Nasopharyngectomy for Nasopharyngeal Adenocarcinoma

Objectives: Nasopharyngeal adenocarcinomas (NPACs) are rare malignant tumors. The treatment of NPACs is usually surgery with resection of normal nasal passage tissues.We introduced an innovative double endoscopic surgery for NPACs patients and evaluated the clinical efficacy of this approach. Methods: The clinical data of 4 NPACs patients who underwent radical endoscopic nasopharyngectomy using a combined transnasal and transoral approach were analyzed to determine the efficacy of this surgery. The endpoints were en bloc resection and relief of clinical symptoms. Results: All surgeries were successfully performed without any severe postoperative complications or death. Postoperative MRI revealed that en bloc resection was achieved for all patients with NPACs, and they had high quality of life without postoperative complications. Conclusions: The transnasal-transoral approach to endoscopic nasopharyngectomy for nasopharyngeal adenocarcinoma is safe and effective.
