Abstract:
Objective: To summarize the clinical experience and treatment results of endoscopic transoral resection of metastatic retropharyngeal lymph nodes (MRPLN) in nasopharyngeal carcinoma (NPC) via posteroinferior eustachian tube approach. Methods: The clinical data of 37 patients with NPC who underwent endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN in Xuanwu Hospital, Capital Medical University from 2010 to 2020 were analyzed retrospectively. There are 28 males and 9 females, aged from 31 to 72 years. The clinicopathological features such as gender, age, primary tumor stage, stage, side and size of MRPLN were recorded and analyzed. The surgical procedures of endoscopic transoral resection of MRPLN via posteroinferior eustachian tube approach were described. The MRPLN resection, perioperative complications and follow-up results were also summarized. Results: The primary tumors of 37 cases were determined as rT1 stage in 2 cases, rT2 stage in 30 cases and primary T2 stage in 5 cases in this study. There were 33 cases of unilateral MRPLN(89.2%), 4 cases of bilateral ones (10.8%), 36 cases in N1 stage, and 1 case in N3 stage. Single lymph node was detected in 23 cases(62.2%), and 2-5 lymph nodes in 14 cases(37.8%). Endoscopic transoral surgery via posteroinferior eustachian tube approach was completed in all cases. Total MRPLN resection was obtained in 35 cases (94.6%) with one-stage operation, and subtotal resection was achieved in 2 cases whose MRPLN involved the wall of internal carotid artery. No serious complications occurred in the perioperative period. During the follow-up period (median follow-up period 53.1 months), no recurrence of MRPLN was observed in patients who received total resection. And 8 patients (21.6%) died from different causes. Conclusion: Endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN is a practicable and effective surgical option, but the long-term effect still needs longer follow-up and summary of bulk cases.
