腮腺区域切除术对动、静态唾液总流率的影响

Effect of partial superficial parotidectomy on rest and stimulated full salivary flow rate

目的探讨腮腺区域性切除术对动、静态唾液总流率的影响及在保留残余腺体功能方面的作用。方法对行腮腺区域性切除术的腮腺良性肿瘤患者30人,分别于手术前和术后3个月收集静态混合唾液、酸刺激动态混合唾液及双侧腮腺液,计算各组唾液流率,并进行统计学分析。结果术前患侧腮腺流率明显低于健侧。所有病例手术后患侧腮腺均能收集到唾液,但流率明显降低;而静态及动态唾液总流率与术前相比没有明显降低。结论腮腺良性肿瘤的发生明显影响腮腺唾液分泌功能。腮腺区域性切除术后患侧腮腺仍能够保留部分分泌功能。腮腺区域性切除术虽未能引起对侧腺体代偿,但对患者口腔内唾液分泌总量的影响较小。

Objective To evaluate the effect of the partial superficial parotidectomy on rest and stimulated full salivary flow rate. Methods Thirty patients with benign tumors of parotid gland, treated by partial superficial parotideetomy were included. Resting whole saliva, stimulated whole saliva and bilateral parotid saliva were collected before and three months after partial superficial parotidectomy. Flow rates were calculated. Results The parotid salivary flow rates in the affected side before operation were significantly lower than that in the normal side. The parotid saliva in the affected side of all patients after operation could be collected, but significantly reduced. Compared to preoperation, resting and stimulated whole salivary flow rate had no significant change. Conclusion Parotid gland benign tumor affects the parotid saliva quantity. Parotid gland remained partial secretion function after partial superficial parotidectomy. Partial superficial parotidectomy has little influence on whole saliva secretion.
