Comparative outcomes of extracapsular dissection and superficial parotidectomy

Abstract

Background: Retrospective analysis of extracapsular dissection (ECD) and superficial parotidectomy (SP).

Aims/objectives: Comparing the outcomes of ECD and SP in surgery of benign parotid masses.

Material and methods: Total of 136 patients included in the study. The inclusion criteria were pathologically proven benign FNA biopsy, lack of deep lobe invasion and single tumour diameter lower than 4 cm, absence of radiologically and clinically malignant lesion and facial paralysis at the time of diagnosis.

Objectives: Drain volumes and seroma presence, clinical evaluation of face nerve function; signs of infective complications were collected from patients’ clinic chart. Complications and recurrence rates were obtained from follow-up forms.

Results: The mean follow-up period was 42.53 ± 14.88 months. In SP group, three patients with disease recurrence were found, 8 (10.2%) had early facial nerve paralysis (grade 2 and 3) and 11 (14.1%) had Frey’s syndrome. No postoperative complication, early facial paralysis and recurrence were observed in ECD group.

Conclusion and significance: ECD procedure was found to be as successful as SP in the selected patient group in approach to the pathologically proven and single benign parotid masses with similar recurrence and lower complication rates compared to the SP.

背景：回顾性分析囊外剥离术（ECD）和浅表腮腺切除术（SP）。

目的：比较良性腮腺肿块手术中ECD和SP的结果。

材料和方法：共136名患者被纳入研究。入选标准为经病理证实的良性FNA活检, 缺乏深叶浸润和单个肿瘤直径低于4 cm, 诊断时无放射学和临床恶性病变以及面部麻痹。

目的：排液量和血肿的存在, 面神经功能的临床评估；从患者的临床图表中收集了感染并发症的迹象。并发症和复发率得自随访表。

结果：平均随访期为42.53±14.88个月。在SP组中, 发现3例复发患者, 8例（10.2％）患有早期面神经麻痹（2和3级）, 11例（14.1％）患有Frey综合征。 ECD组未观察到术后并发症、早期面瘫和复发。

结论和意义：在治疗经病理证实和单一良性腮腺肿块方面, 与SP相比, ECD手术在选定的患者组中一样成功, 具有相似的复发率且较低的并发症率。
