这项研究的目的是评估使用纤维蛋白密封剂的无引流腮腺切除术对住院时间的影响，术后血清肿和相关并发症。为此,在一个学术中心进行了回顾性配对病例对照系列.所有接受无引流腮腺切除术的患者，包括深叶肿瘤和翻修手术，与插入抽吸排放口的匹配对照进行比较。主要结果是住院时间和术后血清肿。共有123例患者（41例和82例对照）被纳入研究。纤维蛋白密封剂组全腮腺切除术率高于对照组(25.0%vs.10.5%,p=0.054)。纤维蛋白密封剂组的住院时间明显缩短（1.0±0.3天与1.5±0.6天，p分别<0.001)。在术后血清肿方面，纤维蛋白密封剂组与对照组之间无统计学差异（9.8％vs.14.6%,分别为p=0.574)，期望率(7.3%对14.6%,p=0.381),和感染率(0%vs.3.7%，p=0.550）。总之,无引流腮腺切除术不会增加术后血清肿发生率和相关并发症，也可以实施翻修手术。
The aim of this study was to evaluate the impact of drainless parotidectomy using fibrin sealant on length of stay, post-operative seroma and related complications. For this purpose, a retrospective matched
case-control series was held in a single academic center. All patients who underwent drainless parotidectomies, including deep lobe tumors and revision surgeries, were compared to matched controls in which a suction drain was inserted. Main outcomes were length of hospital stay and post-operative seroma. A total of 123 patients (41 cases and 82 controls) were included in the study. Fibrin sealant group had higher rates of total parotidectomy compared with the control group (25.0% vs. 10.5%, p = 0.054). Length of stay was significantly shorter in the fibrin sealant group (1.0 ± 0.3 days vs. 1.5 ± 0.6 days, p < 0.001, respectively). No statistically significant difference was found between the fibrin sealant group and the control regarding post-operative seromas (9.8% vs. 14.6%, p = 0.574, respectively), aspirations rate (7.3% vs. 14.6%, p = 0.381), and infection rates (0% vs.3.7%, p = 0.550). In conclusion, drainless parotidectomy does not increase post operative seroma rates and related complications, and can also be implemented for revision surgery.
