Abstract: 【Abstract】 Objective To evaluate the clinical effect of the minimal preauricular and retroauricular incisions in parotidectomy of benign tumor. Methods Thirty patients with benign parotid tumor were reviewed in this study. Parotidectomy was designed as follows: a minimal preauricular and retroauricular incision was used, partial-superficial parotideceomy was applied, the preservation of facial nerve as well as great auricular nerve was carried out in parotidectomy of benign tumor. Follow-up study for3 to 24 months included the cosmetic effect of this incision and the clinical effect. Results The minimal preauricular and retroauricular incision healed uneventfully in all patients without salivary fistulae. After a follow-up, all the patients showed results with no obvious scar and sunken deformity left in face and parotid region. Two patients had temporary facial paralysis but recovered in 3 months with the treatment of cortical hormone and neurotrophic drugs. Four patients felt numb in ear lobe and the symptom was disappeared in 3-10 months post-operation. No patient had presented with clinical Frey's syndrome, as well as no tumor recurrence. Conclusion This minimal preauricular and retroauricular incisionsis a feasible technique, providing excellent cosmetic outcome in the treatment of benign parotid neoplasms.

摘要： 【摘要】目的评估耳屏周小切口在腮腺良性肿瘤切除术中应用的临床价值。方法30例腮腺良性肿瘤患者，应用耳屏周小切口行浅叶部分切除、保留面神经和耳大神经的腮腺良性肿瘤切除术。术后随访3～24个月，观察耳屏周小切口的美观度及临床疗效。结果所有患者均临床Ⅰ期愈合，术后腮腺功能良好，无涎瘘发生。随访，患者双侧外形对称，无凹陷等畸形，手术切口隐蔽，患者对耳周切口美学效果满意。本研究中出现术后暂时性面瘫患者2例，皮质激素并配合神经营养药物综合治疗后3个月均恢复正常；出现术后耳垂麻木不适患者4例，手术后3～10个月均逐渐恢复。本研究中所有患者均未出现味觉出汗综合征，无肿瘤复发。结论耳屏周小切口隐蔽、瘢痕小、并发症低，术后美容效果理想。
