Extracapsular dissection for Warthin tumor in the tail of parotid gland

Abstract

Conclusions: Extracapsular dissection conferred the advantage of reduced operation time and morbidity without any recurrence, and it could be considered as the treatment of choice for Warthin tumors in the tail of the parotid gland.

Objective: The purpose of this study is to confirm the appropriate surgical procedure for Warthin tumor in the tail of the parotid gland, by comparing the results of extracapsular dissection and superficial parotidectomy.

Materials and methods: The medical records of 72 patients with Warthin tumor in the tail of the parotid gland who underwent surgery between January 2006 and December 2016 were retrospectively reviewed.

Results: In the extracapsular dissection group, a total of 44 parotid gland operations were performed in 40 patients. In the superficial parotidectomy group, a total of 34 parotid gland operations were performed in 32 patients. The operation time was significantly shorter in the extracapsular dissection group than in the superficial parotidectomy group (p<.001, Table 1). One patient in the extracapsular dissection group and five patients in the superficial parotidectomy group had postoperative facial nerve palsy. Recurrence of Warthin tumor in the tail portion of the parotid gland was identified in one patient who underwent superficial parotidectomy.

结论：囊外切除术具有减少手术时间和并发症发生率以及无复发的优势, 可考虑作为腮腺尾沃辛瘤的治疗选择。

目的：本研究的目的是, 通过比较囊外切除术和腮腺浅叶切除术的结果, 来确定腮腺尾沃辛瘤合适的治疗方法, 。

材料和方法：对72例患有腮腺尾沃辛瘤, 并在2006年一月和十二月期间接受手术的病人的临床资料进行回顾性分析。

结果：在囊外解剖组中, 40例患者, 共经受了44次腮腺手术。在腮腺浅叶切除术组中, 32例患者共经受了34次腮腺手术。囊外切除术组与腮腺浅叶切除术组相比, 手术时间明显缩短（P＜.001, 表1）。囊外切除术组的一个病人和腮腺浅叶切除术组的五个病人在术后患面部神经麻痹。接受腮腺浅叶切除术的病人中只有一个复发了腮腺尾沃辛瘤。
