This study compared the complete closure versus the exposure of remnant parotid parenchyma in sialocele formation.
This study included 151 patients with benign parotid lesions who underwent partial parotidectomy plus the complete closure or exposure of remnant parotid parenchyma. Two surgical methods of closed or exposed parenchyma were alternatively allocated to consecutive patients without randomization and blinding processes.
Complete closure and exposure of the remnant parotid parenchyma were performed in 81 and 70 patients. Early postoperative complications occurred with temporary events: transient facial weakness, 24 (16%); hematoma, 9 (6%); wound infection, 1 (0.7%) without statistical difference between the two groups (p > 0.1). Postoperative sialocele was more frequently found in the exposure group (n = 15) than the closure group (n = 4; p = 0.003).
The complete closure of remnant parotid parenchyma is preferred over the exposure of injured parenchymal parenchyma to prevent postparotidectomy sialocele.
本研究比较了涎瘘形成中残余腮腺实质的完全闭合与暴露。
本研究纳入了 151 例接受腮腺部分切除术并完整闭合或暴露残余腮腺实质的良性腮腺病变患者。两种闭合或暴露腮腺实质的手术方法被交替用于连续患者，没有随机化和盲法过程。
81 例患者行完全闭合术，70 例患者行暴露术。早期术后并发症均为暂时性事件：暂时性面瘫 24 例（16%）；血肿 9 例（6%）；伤口感染 1 例（0.7%），两组间无统计学差异（p＞0.1）。暴露组术后涎瘘的发生率（n=15）高于闭合组（n=4；p=0.003）。
与暴露受损的实质组织相比，完整闭合残余腮腺实质更有助于预防腮腺切除术后涎瘘。
