Objective To study the clinica feature of intraparotid neurilemmoma of the facial nerves. 6 cases of neurilemmoma of the facial nerve in the parotids are presented, 4 cases had the numbness and swollen pains. 5 cases had been misdiagnosed for parotid mixed tumor before operative.Result The nerves in two of them had been reserved in the operations, two cases had been excised (one of them had been mistaken for malignant tumor).Conclusion The clinical characteristics, diagnosis, prevention and the...

Objective To study the clinica feature of intraparotid neurilemmoma of the facial nerves. 6 cases of neurilemmoma of the facial nerve in the parotids are presented, 4 cases had the numbness and swollen pains. 5 cases had been misdiagnosed for parotid mixed tumor before operative.Result The nerves in two of them had been reserved in the operations, two cases had been excised (one of them had been mistaken for malignant tumor).Conclusion The clinical characteristics, diagnosis, prevention and the treatment of the complications during operations about the intraparotid neurilemmoma of the facial nevers were also discussed. Neurilemmoma should be suspected when there is functional disturbance or paralysis of facial nerve, specially when benign diagnostic imaging and/or extraparotid neurogenic lesions are present. The tumors come from the trunk and main branches of the facial nerve. Enueleation of the tumor with preservation of the nerve trunks is preferred in benign lesions. In malignant neurilemmoma an extensive resection with immediate nerve grafting is indicated.

目的:探讨腮腺内面神经鞘瘤的临床特点。方法:6例患者均行腮腺浅叶及肿瘤切除术。结果:6例中2例术时神经保存完好,术后无面瘫,2例施行神经切除。结论:腮腺区肿瘤出现面神经功能障碍,应考虑此病。肿瘤起自面神经干式主要分支,手术须保留面神经主干而将肿瘤切除;在恶性肿瘤患者当肿瘤广泛切除后,应立即进行神经修复。

Purpose To explore imaging characteristics of parotid mixed tumor and to study shortage and advantage of EBCT CTS 3D CT Flow scan and MRI in diagnosis of the tumor. Methods 28 cases of parotid mixing tumor were imaged with EBCT CTS 3D CT Flow scan and MRI. The imaging signs were compared with the pathologic findings. Results CTS shows shape and border of the lesions well, and 3D CT shows parotid masses directly and stereoscopicly. Time density dynamic perfusion curve of the tumor...

Purpose To explore imaging characteristics of parotid mixed tumor and to study shortage and advantage of EBCT CTS 3D CT Flow scan and MRI in diagnosis of the tumor. Methods 28 cases of parotid mixing tumor were imaged with EBCT CTS 3D CT Flow scan and MRI. The imaging signs were compared with the pathologic findings. Results CTS shows shape and border of the lesions well, and 3D CT shows parotid masses directly and stereoscopicly. Time density dynamic perfusion curve of the tumor is slow rising and slow descending. MRI is the best in showing composition of the tumor and relation with facial nerve. Conclusion The parotid mixed tumor has some characteristic imaging signs. It could diagnose the tumor correctly with combined these five imaging methods. [

目的 探索腮腺混合瘤影像学征象特点和EBCT、CTS、3D CT、流动扫描和MRI对混合瘤诊断的优缺点。方法 对 2 8例分别进行此五种影像学检查 ,结果与手术病理所见相对照。结果 CTS对病灶边界形态的显示较为有利 ;3D CT可以显示病灶的立体形态及其与腮腺导管等周围结构的关系 ;混合瘤时间 密度曲线呈缓升缓降型 ;MRI对显示病变的成份和其与面神经的关系最为理想。结论 混合瘤影像学上具有一定的特点 ,几种检查互补有利于正确诊断。

Objective To test the expression of VEGF in oral tumors, and to investigate the relationship between VEGF expression and the nature and malignancy of oral tumors. Methods SABC immunohistochemistry was used to investigate the expression of VEGF in 86 cases. Results The gross positive rate of VEGF was 33% (28/86), while the positive rate of VEGF in SCC was 55% (23/42), which was significantly higher than those in papilloma(10% ,2/20) and parotid mixed tumor(13% ,3/24)(P < 0.001) .VEGF expression was negatively...

Results The gross positive rate of VEGF was 33% (28/86), while the positive rate of VEGF in SCC was 55% (23/42), which was significantly higher than those in papilloma(10% ,2/20) and parotid mixed tumor(13% ,3/24)(P < 0.001) .VEGF expression was negatively related to tumor differentiation degree( r = - 0.40, P < 0.05) , but positively related to lymph node metastasis( r = 0.39, P < 0.05) . Conclusion ①The positive rate of VEGF in malignant oral tumors was significantly higher than that in benign tumors, which suggested that VEGF expression might be helpful to distinguish malignant tumors from benign ones.②VEGF expression in SCC was related to differentiation degree of tumors and lymph node metastasis, which suggested that the increase of VEGF expression promoted malignancy of oral SCC.

目的 研究口腔肿瘤组织中血管内皮细胞生长因子(vascular endothelial growth factor,VEGF)的表达情况,探讨其与肿瘤性质及恶性进展的关系。方法 采用免疫组化SABC法检测86例口腔肿瘤组织中VEG蛋白的表达情况。结果 本组VEGF的总表达率为33%(28/86),鳞癌中VEGF的表达率显著高于乳头状瘤和腮腺混合瘤(P<0.001)。VEGF表达与肿瘤分化程度呈负相关(列联系数r=-0.40,P<0.05);与淋巴结转移呈正相关(列联系数r=0.39,P<0.05)。结论 口腔恶性肿瘤较良性肿瘤组织中VEGF的表达率显著增高,VEGF表达可能有助于口腔良恶性肿瘤的鉴别。鳞癌组织中VEGF表达与肿瘤的分化程度和淋巴结转移有关,VEGF表达的增加促进了口腔鳞癌的恶性进展。
