Martin(1951)处理颈部转移肿瘤经典的颈淋巴结清扫术(NRNS)沿用至今,但对颈上深部病变的清理尚感不足。作者介绍扩大的NRNS暴露颅底的径路,可获在颅底结扎颈内静脉、游离面神经、暴露颈总动脉上至颅底水平。此手术径路能有效地完全切除颈上深部病变。手术方法:在标准NRNS的水平切线向上延至耳后(距耳后沟3cm),经耳上达颧弓根上方3cm呈“C”形切口。切开软组织深达颅骨膜下,向前分离至耳前棘,切断耳道软骨和骨
Martin (1951) has been using classical cervical lymph node dissection (NRNS) for metastatic cervical neoplasms to the present day, but the treatment of deep neck lesions is not yet adequate. The authors describe the expanded NRNS exposure to the skull base approach that allows the ligation of the internal jugular vein at the base of the skull, free facial nerve, and exposure of the common carotid artery to the skull base level. This surgical approach can effectively remove the deep cervical lesions. Surgical methods: In the standard NRNS horizontal tangential extension up to the ear (from the posterior groove of the ear 3cm), the ear up to the top of the zygomatic arch 3cm was “C” incision. Cut deep soft tissue under the skull subperiosteal, forward separation to the ear before spine, cut off the ear canal cartilage and bone
