目的：比较腮腺良性肿瘤改良术式结合二次翻瓣法较传统术式对患者耳垂及外耳廓区皮肤感觉恢复的影响。方法选择2005年7月至2014年6月在我院行腮腺良性肿瘤切除术患者22例，随机分为实验组和对照组，每组11例。实验组行保留腮腺咬肌筋膜，二次翻瓣法，解剖并保留耳大神经耳后、耳垂支和腮腺区域性切除术的腮腺良性肿瘤改良手术方式。对照组按常规行腮腺肿瘤及腮腺浅叶或全叶切除术。术后观察、随访6个月。采用SPSS 13．0统计软件包中的检验，对两组患者术后耳垂及外耳廓区皮肤感觉恢复情况进行χ2比较。结果实验组中患者耳垂及外耳廓区感觉恢复情况明显优于对照组，差异具有显著性（P＜0．05）。结论改良术式结合二次翻瓣法比传统手术方式在腮腺良性肿瘤治疗中对保存耳垂及外耳廓皮肤感觉具有明显优势。%Objective To compare the effects of modified operation combined with secondary disc method in benign tumor of parotid gland and traditional surgery on the sensory recovery of the auricular lobule and auricle skin.Methods 22 patients with parotid benign tumor who received parotidectomy in our hospital from2005.7 to 201.6 were randomly divided into experimental group ( n =11 ) and control group ( n =11 ) .In experimental group, the modified operation of benign tumor in parotid gland included regional ectomy of parotid, secondary disc method, reservation of fascia parotidea masseterica and dissection and reservation of the post aurem and auricular lobule branches of great auricular nerve.In the control group, the 11 patients were operated by the conventional technique.After 6 months, the effects of 2 groups on the sensory recovery of the skin of the auricular lobule and auricle region were evaluated.The data were analyzed with SPSS 13.0 software package for x2test. Results The sensory recovery of the skin of the auricular lobule and auricle region in experimental group was better than in control group.The difference was statistically significant (P<0.05).Conclusions The modified operation combined with secondary disc method in benign tumor of parotid gland has obvious advantages in the sensory recovery of the skin of the auricular lobule and auricle region comparing with the traditional operation mode.
