ABSTRACT
Objective:
To investigate the application and effect of capillary fascia preservation between the recurrent laryngeal nerve (RLN) and common carotid artery (fascia preservation method) in nerve protection when dissecting right level â ¥ lymph nodes for patients with papillary thyroid carcinoma.Methods:
A retrospective cohort study enrolling 195 patients with papillary thyroid carcinoma undergoing right level â ¥ lymph node dissection in Beijing Tongren Hospital from March 2021 to August 2022 was carried out. The RLN was dissected by fascia preservation method in study group and by routine method in control group. The intraoperative electrical signal amplitude of the RLN, the number of dissected lymph nodes, and the postoperative complications were recorded and analyzed.Results:
A total of 195 patients (study group 94 cases, control group 101 cases) were collected. There were 71 males and 124 females, with the median age of 32 (39, 51) years. In the study group, the total number of right level â ¥ lymph nodes was significantly larger than the number of right â ¥a level lymph nodes [8 (6, 11) vs 6 (4, 8), P<0.001]. There were no significant differences between the two groups in the number of level â ¥a or level â ¥b lymph nodes [â ¥a 6 (4, 8) vs 5 (3, 7), P=0.373; â ¥b 3 (1, 4) vs 2 (1, 4), P=0.337] and metastasis rate [â ¥a 51.1% (48/94) vs 52.5% (53/101), P=0.844; â ¥b 12.8% (12/94) vs 15.8% (16/101), P=0.541]. The ratio of electromyography (EMG) amplitude R2 in lower level â ¥ and entry into larynx (grouped as>90%, 50%~90%,<50%) in the study group was significantly higher than that in the control group (P<0.001). No significant differences were detected between the two groups in temporary RLN paralysis [1.1% (1/94) vs 2.0% (2/101), P=1.000].Conclusions:
Fascia preservation method can decrease the stimulus and traction to RLN and preserve the capillary network serving RLN. It can thoroughly dissect lymph nodes and decrease the injury of RLN.
