功能性腮腺切除术在腮腺浅叶良性肿瘤手术中的应用

Clinical application of functional parotidectomy in benign tumor of superficial lobe of parotid gland

目的探讨功能性腮腺切除术在腮腺浅叶良性肿瘤手术中的临床应用价值。方法首诊腮腺浅叶单发良性肿瘤病例51例,肿瘤直径均≤3.0 cm,采用保留耳大神经、腮腺导管及部分腮腺、重建腮腺咬肌筋膜的功能性腮腺切除术治疗,距肿瘤边缘0.5～1.0 cm处的正常腺体组织内切除肿瘤,随访2个月～2年,观察术后并发症的发生及肿瘤复发情况。结果所有病例术后面部畸形较轻,腮腺功能良好,耳垂无明显麻木,无涎瘘及味觉出汗综合征,无永久性面瘫,其中5例出现暂时性面瘫。随访期间肿瘤无复发。结论功能性腮腺切除术手术创伤小,术后并发症少,在体积较小(≤3.0 cm)的腮腺浅叶良性肿瘤手术中具有很高的临床应用价值。

Objective To investigate the clinical value of functional parotidectomy in benign tumor of superficial lobe of parotid gland. Methods Fifty - one patients with benign tumors in superficial lobe of parotid gland（≤3.0cm） were treated with functional parotid- ectomy, preserving the great auricular nerve, conserving the master duct and main normal parotid tissue, reconstructing the parotidmasseter fascia, reseeting the tumor in the 0.5 - 1.0 cm away from the edge of the tumor within the normal glandular tissue. All patients were followed up for 2 months to 2 years to investigate the rate of postoperative complications and recurrence. Results There was slight facial deformity in 51 patients. The function of parotid gland was nearly normal. There was no obvious earlobe numb, no salivary fistula and gustatory sweating syndrome, no permanent facial nerve injury, but there was transient facial nerve palsy in 5 cases. There was no recurrence during the fol- lowed - up. Conclusion Functional parotideetomy has a high clinical value with small surgical trauma and less postoperative complications in smaller benign tumor（ ≤ 3.0 cm） of superficial lobe of parotid gland.
