Neck dissection of levels I and IIB is time consuming and can cause several comorbidities. The aim was to analyze whether levels I and IIB need to be dissected in patients with oropharyngeal cancer and clinical N0 or N+ neck.
A retrospective analysis of 77 patients with oropharyngeal cancer was carried out with evaluation of the incidence of neck node metastasis in levels I and IIB.
None of the patients with cN0 neck had metastases in level I or IIB; 12.8% of the patients with cN+ neck had metastases in level I, 35.1% in level IIA and 25.6% had metastases in level IIB.
Levels I and IIB should be dissected in cN+ neck in order to achieve maximal oncological safety. The preservation of levels I and IIB in cN0 neck seems to be justified in terms of improving functional results and concomitant reduction of operation time.
颈清扫术 I 区和 IIB 区耗时较长，并可能导致多种并发症。本研究旨在分析对于临床 N0 或 N+颈部的口咽癌患者，是否需要清扫 I 区和 IIB 区。
对 77 例口咽癌患者进行回顾性分析，评估 I 区和 IIB 区颈部淋巴结转移的发生率。
无 cN0 颈部的患者在 I 区或 IIB 区发生转移；cN+颈部的患者中有 12.8%在 I 区、35.1%在 IIA 区和 25.6%在 IIB 区发生转移。
为了达到最大的肿瘤安全性，cN+颈部应行 I 区和 IIB 区清扫。在 cN0 颈部保留 I 区和 IIB 区似乎在改善功能结果和同时减少手术时间方面是合理的。
