颈部转移是影响喉癌患者预后最重要的因素之一 ,也是此类病人肿瘤复发最常见的类型。因为目前微小的转移灶在术前不能被察觉 ,故选择性颈侧廓清术越来越多地作为治疗颈部无阳性临床体征喉癌患者的标准治疗方法 ,以达到降低癌肿复发率的目的。对于局限性 ,隐匿性淋巴结转移的患者 ,选择性颈侧廓清术与改良颈廓清术有相同的疗效。 Neck metastasis is one of the most important factors affecting the prognosis of patients with laryngeal cancer, but also the most common type of tumor recurrence in these patients. Because microscopic metastases can not be detected preoperatively, selective neck dissection is increasingly used as a standard treatment for patients with laryngeal cancer who have no clinical signs of the neck in order to achieve the goal of reducing the recurrence rate of the cancer . For patients with localized, occult lymph node metastases, selective neck dissection and modified neck dissection have the same effect.
