改良腮腺肿瘤切除术的临床研究

目的:探讨改良腮腺肿瘤切除术在腮腺良性肿瘤手术中的临床应用价值。方法:腮腺首发良性肿瘤146例,肿瘤直径≦3.0cm,采用保留腮腺咬肌筋膜、腮腺导管、耳大神经的腮腺部分切除术治疗,距肿瘤边缘0.5～1.0cm正常腺体组织内切除肿瘤。随访2～5年,观察术后并发症及肿瘤复发情况。结果:全部患者术后面部畸形较轻,腮腺功能良好,耳垂无明显麻木,无永久性面神经损伤,肿瘤无复发。出现暂时性面瘫45例,Frey’s综合症23例。结论:改良腮腺肿瘤切除术手术创伤小,术后并发症少,具有很高的临床推广价值。

Clinical Study on Modified Parotidectomy in Benign Tumor of Parotid Gland

Objective: To investigate the clinical value of modified parotidectomy in benign tumor of parotid gland.Methods: One hundred and forty-six patients with benign tumors in parotid gland(the diameter of the tumors was less than 3.0 centimeter) were treated with modified parotidectomy,conserving the master duct and main normal parotid tissue,retaining the sub-superficial musculoaponeurotic system and the great auricular nerve.All patients were followed up for 2-5 years to investigate the rate of postoperative complication and recurrence.Result: There was slight facial deformity in 146 patients.The function of parotid gland was nearly normal.There was no recurrence,no obvious earlobe numb and no permanent facial nerve injury during the followed-up,but there was transient facial nerve palsy in 45 cases,and Frey’s syndrome in 23 cases.Conclusion: Modified parotidectomy can protect the main function of parotid gland,reduce various kinds of postoperative complications.
