腮腺肿瘤,以混合瘤发病率最高。此瘤的被膜,有的完整,有的不完整,有时被膜为瘤细胞浸润,肿瘤组织突出被膜,伸向正常组织中。甚至有学者认为:混合瘤的被膜是由腺体组织被肿瘤压缩形成,并非真性纤维性被膜,此膜既薄又不完整。因此,单纯的肿瘤剥离手术,常达不到根治的目的,易将肿瘤遗留于组织中,据统计单纯肿瘤剥离手术,术后复发率可达20—45％我们从63年起、对腮腺混合瘤,经单纯剥离手术,术后复发的病例及近三年来,无论是初发或术后复发病例,均常规采用保存面神经手术切除腮腺及肿瘤的治疗方法,获得良好的治疗效果。现小结如下:
Parotid tumors, the highest incidence of mixed tumors. The tumor capsule, some complete, and some incomplete, and sometimes the membrane for the infiltration of tumor cells, tumor tissue prominent capsule, extending to normal tissue. Some scholars even think: mixed tumor capsule by the gland tumor tissue is compressed to form, not true fibrous capsule, the film is thin and incomplete. Therefore, a simple tumor stripping surgery, often not up to the purpose of cure, easy to leave the tumor in the tissue, according to the statistics of simple tumor stripping surgery, postoperative recurrence rate of up to 20-45% We from 63 onwards, the parotid gland mixed Neoplasms, simple dissection surgery, postoperative recurrence and the past three years, either initial or postoperative recurrence, are routinely used to save facial nerve resection parotid and tumor treatment, access to good treatment. Now summarized as follows:
