颈廓清术目的在于尽可能彻底地清除来自头颈部癌的转移的淋巴结。经典性手术需要牺牲胸锁乳突肌、颈内静脉和副神经。不少作者的研究结果表明:对于头颈部鳞癌患者,颈部淋巴结临床摸不着或淋巴结大小不超过3cm直径者,采用改良根治性颈廓清术是可取的,即术中保存胸锁乳突肌、颈内静脉和副神经,其术后效果与标准根治性颈廓清术相当,而对其预后无不良影响。作者们自1977年以来为48例各种头颈部鳞癌 The purpose of neck dissection is to remove metastatic lymph nodes from head and neck cancer as thoroughly as possible. Classic surgery requires sacrifice of the sternocleidomastoid muscle, internal jugular vein, and accessory nerves. Many authors’ research results show that: For patients with head and neck squamous cell carcinoma, cervical lymph nodes clinically inexplicable or lymph node size does not exceed 3cm in diameter, the use of modified radical neck dissection is desirable, that is, intraoperative preservation of sternocleidomastoid Muscle, internal jugular vein, and accessory nerves have similar postoperative effects to standard radical neck dissection without adversely affecting their prognosis. The authors have studied 48 head and neck squamous cell carcinomas since 1977
