Abstract

OBJECTIVES

The aim of the study was to compare multifocal extracapsular dissection with complete parotidectomy in the treatment of unilateral multifocal cystadenolymphomas of the parotid gland.

MATERIALS AND METHODS

The records from all patients treated for unilateral multifocal cystadenolymphomas of the parotid gland at a tertiary referral center between 2000 and 2016 were retrospectively analyzed.

RESULTS

203 patients were included in the study. 96 patients were managed by multifocal extracapsular dissection, 107 patients underwent complete parotidectomy. Metachronous tumors were detected in 7 cases (3.4%) with a significant difference in the occurrence rate between multifocal extracapsular dissection (7/96, 7.3%) and complete parotidectomy (0/107, 0%) (p = 0.004). Permanent facial palsy was significantly more common after complete parotidectomy (21/107, 19.6%) than multifocal extracapsular dissection (2/96, 2.1%) (p = 0.000).

CONCLUSIONS

The functional benefit of multifocal extracapsular dissection was counterbalanced by the advantage of complete parotidectomy, in terms of recurrences. Extracapsular dissection is at its limit in cases of multifocal cystadenolymphomas and the indication for it should be thoroughly verified in each and every case.

摘要

目的

本研究旨在比较多灶性囊外解剖与腮腺全切除术治疗单侧多灶性囊性腺淋巴瘤的疗效。

材料与方法

回顾性分析 2000 年至 2016 年间，一家三级转诊中心收治的单侧多灶性囊性腺淋巴瘤患者的资料。

结果

共纳入 203 例患者，96 例行多灶性囊外解剖，107 例行腮腺全切除术。7 例（3.4%）患者发生了异时性肿瘤，多灶性囊外解剖（7/96，7.3%）与腮腺全切除术（0/107，0%）的发生率存在显著差异（p=0.004）。完全切除术后发生永久性面瘫的比例明显高于多灶性囊外解剖（21/107，19.6%）（p=0.000）。
