发生于腮腺的肿瘤,向后可累及外耳道,向上可侵犯中颅窝底部,向内则可破坏出入颈静脉孔的神经血管。在这些解剖结构复杂的区域,如手术切除范围不当,可导致肿瘤复发。作者自1987～1991年间,采用标准腮腺全切术与颞骨岩部次全切除术(subtotal petrosectomy)治疗27例生长活跃的腮腺肿瘤,其中22例为恶性肿瘤,10例为复发肿瘤。27例患者中,男性15例, Occur in the parotid tumor, the posterior can affect the external auditory meatus, can be infringed at the bottom of the middle of the skull, inward can be destroyed out of the jugular vein neurovascular. In these complex areas of the anatomy, such as surgical removal of inappropriate range, can lead to tumor recurrence. The authors used standard total parotidectomy and subtotal petrosectomy to treat 27 active parotid tumors from 1987 to 1991, of which 22 were malignant and 10 were recurrent tumors. 27 patients, 15 males,
