腮腺浅叶部分切除术与浅叶切除术治疗腮腺浅叶良性肿瘤的回顾性研究

Retrospective study of partial superficial parotidectomy and superficial parotidectomy on superficial parotid benign tumor

目的:评估腮腺浅叶部分切除术(PSP)与浅叶切除术(SP)治疗腮腺浅叶良性肿瘤的疗效,为临床术式选择提供依据。方法:168例腮腺浅叶良性肿瘤手术患者根据术式不同分为PSP与SP两组,对比两组手术情况、并发症、复发率及腺体功能,相关数据采用SPSS 22.0软件进行统计分析。结果:PSP组手术切口长度和时间分别为(6.65±1.17)cm及(82.25±11.56)min,SP组分别为(10.86±1.65)cm及(121.42±17.32)min,PSP组优势明显(P<0.01);PSP组并发症发生率显著低于SP组(P<0.05);PSP组保留腮腺大部分功能,SP组无腮腺分泌功能;两组术后复发率无显著差异(P>0.05)。结论:PSP治疗腮腺浅叶良性肿瘤临床效果好,在复发率未见显著增加的前提下手术切口、范围、时间均显著减小,并发症发生率显著下降,且可有效保留腺体功能,是一种可靠、可行、值得推广的手术方法。

Objective： To compare the clinical effect between partial superficial parotidectomy（PSP） and super- ficial parotidectomy（SP） through a retrospective analysis and to provide evidence for the benign tumor surgical strategy. Method.. According to different surgical strategies performed, 168 patients with superficial parotid benign tumor were reviewed and divided into PSP group and SP group. Clinical data was compared between two groups from different aspects, including operation condition, complications, recurrence rate, as well as parotid function. SPSS 22.0 software was used in statistical analysis. Result： PSP group has an average operative incision length of （6.65±1.17）cm, and average operation time of（82.25±11.56）min, while SP group is（10.86±1.65）cm and （121.42 ± 17.32）min. So, compared with the SP group, PSP has obvious advantages in operation conditions （P〈 0.01）. Furthermore,PSP group also presents an advantage over SP group in occurrence of postoperative complica- tions （P〈0.05）, while there is no significant difference between two groups in palindromia rate（P〉0.05）. As for the maintenance of parotid gland functions, PSP group could retain most of parotid functions, but no function would be retained in SP group. Statistical analysis confirms the significance（P〈0.05）. Conclusion：Compared with SP, in PSP there is declined complication incidence but no increased palindromia recurrence. However, PSP has an apparent advantage on decreased surgical incision length, downsealed operation scope, reduced operation time and retained original functions of gland. All these advantages present the reliability and feasibility of PSP in treating superficial parotid benign tumor.
