近年来,手术切除良性腮腺混合瘤的复发率已经降低。这是由于外科手术改进的结果,单纯切除肿块的方法已被废弃,普遍地采用了腮腺浅叶切除术。良性腮腺混合瘤或多形性腺瘤乃腮腺最常见的肿瘤,术后局部复发的处理,仍为临床上经常遇到的问题。对于这种情况,外科医生必须选择最有效的术式,并要决定是否保留或切除面神经。同时也面临着由于既往手术所致的解剖关系的异常,以及瘢痕组织增多的问题。本文汇集了美国Texas洲癌症中心M.D,Anderson医院及肿瘤研究所二十年的经验,以期对良性
In recent years, the recurrence rate of surgical resection of mixed benign parotid gland tumors has decreased. This is due to the improved surgical results. The method of simple removal of the mass has been abandoned, and the parotid superficial resection has been widely used. Benign parotid mixed tumors or pleomorphic adenomas are the most common tumors of the parotid gland. The treatment of local recurrence after surgery is still a clinical problem. In this case, the surgeon must select the most effective surgical procedure and decide whether to retain or resect the facial nerve. At the same time, it is also faced with the anomaly of the anatomical relationship caused by the previous surgery, as well as the increase of scar tissue. This article brings together twenty years of experience from M.D., Anderson Hospital and Cancer Institute in the Texas Cancer Center in the United States, with a view to benign
