【摘要】 目的:评价腮腺良性肿瘤的包膜外切除手术的临床效果。方法:对32例腮腺良性肿瘤采取包外膜切除治疗。腮腺良性肿瘤主要包括多形性腺瘤、肌上皮瘤、腺淋巴瘤等。肿瘤一般小于4cm,主要位于腮腺浅叶及后下部位。肿瘤切除在肿瘤包膜外约0.5cm正常腮腺组进行,一般不主动解剖面神经。结果:术后随访约10%患者出现暂时性面瘫,但均在短时间内恢复。经最长5年的观察未见肿瘤复发。患者的面部外形和腮腺功能保存良好。结论:腮腺良性肿瘤包膜外切除是不同于腮腺肿瘤区域切除或腮腺部分切除,保留更多腮腺组织,没有增加肿瘤的复发。该术式应由有腮腺手术经验的外科医生进行,并经长期临床观察后做出最终评价。更多还原

【Abstract】 Objective:To assess the clinical effect of extracapusular dissection of parotid benign tumors.Methods:32 patients with parotid benign tumors underwent extracapusular dissection(ECD).Parotid benign tumors in this study included pleomorphic adenoma, myoepithelioma,Adenolymphoma,et al.Tumors are less than 4 cm,which were located parotid superfical lobe and its anterior-posterior sites.Extracapusular dissection with a about 0.5 cm margin of normal parotid tissue for Tumor resection.The facial nerve was generally not dissected if the tumor was not in contact with the facial nerve.Results:Transient paresis of facial nerve was observed in the about 10%patients,but they recovered in short time.No local recurrence was observed during the longest follow-up period of 5 years. The facial shape and parotid function of the patients preserved well.Conclusion:ECD of parotid benign tumors is different from local region parotidecomy or partial parotidecomy,preserving more parotid tissue and without increase of tumor recurrence.ECD is should undertaken by the surgeon with experience parotidecomy.Final assessment is also made after long-term clincal observation.更多还原
