This study included 195 patients with parotid lesions who underwent partial or superficial parotidectomy plus closure or non-closure of exposed parotid parenchyma, both with the application of fibrin glue. Two surgical methods of closure and non-closure were allocated to patients without randomization and blinding processes. The primary outcome was FS, and the second outcome was other complication rates.
The closure and non-closure of exposed parotid parenchyma were performed in 102 and 93 patients, respectively. Early postoperative complications occurred with temporary events: transient facial weakness, 32 (16.4%); hematoma, 13 (6.7%); and wound infection, 2 (1.0%), without statistical difference between the two groups (P > 0.1). However, sialocele occurred in the non-closure group (n = 19) more than in the closure group (n = 7) (P = 0.005). In the first postoperative year, decreased sensation and local pain were found in 16 patients (8.2%) and 9 patients (4.6%), respectively, with no statistical difference between the two groups (P > 0.1). FS was found more in the non-closure group (n = 19, 20.4%) than in the closure group (n = 4, 3.9%) (P < 0.001).
The closure of exposed parotid parenchyma and covering fascia is preferred over the non-closure to prevent FS.
方法:这项研究包括195例腮腺病变患者,这些患者接受了部分或浅表腮腺切除术,并封闭或不封闭暴露的腮腺实质,两者都与纤维蛋白胶的应用。将闭合和非闭合的两种手术方法分配给没有随机和盲法过程的患者。主要结果是FS,第二个结果是其他并发症发生率。
结果:分别在102例和93例患者中对暴露的腮腺实质进行了闭合和不闭合,分别。术后早期并发症与暂时性事件一起发生:短暂性面部无力,32(16.4%);血肿,13(6.7%);伤口感染,2(1.0%),两组间无统计学差异(P>0.1)。然而,非闭合组(n=19)比闭合组(n=7)更多(P=0.005)。在术后第一年,16例(8.2%)和9例(4.6%)感觉下降和局部疼痛,分别,两组间无统计学差异(P>0.1)。非闭合组(n=19,20.4%)的FS高于闭合组(n=4,3.9%)(P<0.001)。
结论:对暴露的腮腺实质和覆盖筋膜的闭合比非闭合更可取,以防止FS。
