腮腺嚼肌区有腮腺、嚼肌及面神经组织结构,构成该区域较复杂的解剖特点。在临床上,对发生于该部位肿瘤的来源,性质等诊断是学者们长期关注的问题,我们总结自1983年至1989年在本院完成治疗的104例腮腺嚼肌区肿物,就临床特点做一分析。 1 临床资料:本组病例104例,年龄45岁～75岁,平均39.5岁,其中腮腺来源肿物96例,非腮腺来源肿物8例,包括1例鼻咽癌转移至腮腺。男性:良性肿瘤43例,恶性肿瘤15例;女性:良性肿瘤40例,恶性肿瘤6例。腮腺混合瘤具有复发和恶变倾向,本组织腮腺混合瘤和混合瘤恶变者计78例,占腮腺肿物的81.25％,其中二次治疗者18例,良性恶性各9例。18
The parotid gland chewing muscle area has the structure of parotid gland, chewing muscle and facial nerve, which constitutes a more complex anatomical feature of the area. Clinically, the diagnosis of the origin and nature of tumors that occur at this site is a long-term concern for scholars. We have summarized 104 cases of chewing muscle masses in the parotid gland from 1983 to 1989. Do an analysis. 1 Clinical data: There were 104 patients in this group, aged 45 to 75 years with an average of 39.5 years. Among them, 96 were parotid gland tumors and 8 were non-parotid gland tumors, including 1 nasopharyngeal cancer metastasis to parotid gland. Males: 43 cases of benign tumors and 15 cases of malignant tumors; females: 40 cases of benign tumors and 6 cases of malignant tumors. Mixed tumor of parotid gland has the tendency of recurrence and malignant transformation. There are 78 cases of parotid gland mixed tumor and mixed tumor malignant tumor in this tissue, accounting for 81.25% of parotid gland mass, including 18 cases of secondary treatment and 9 cases of benign malignant. 18
