Benign parotid tumor is one of the most common neoplasms in head and neck region.
Its therapeutic methods have been debatable topics over the past 100 years.
Recently, some surgeons suggest that extracapsular dissection (ECD) instead of
superficial parotidectomy (SP) for treatment of benign parotid tumor. This study
aimed to compare ECD with SP in the treatment of benign parotid tumors by a
meta-analysis.We searched Cochrane Library, PubMed, Embase, Ovid, and Web of
Science databases on February 14, 2015 for studies that assessed clinical
outcomes of SP and ECD as surgical techniques for the management of benign
parotid tumors. Outcome data were evaluated by pooled risk ratio (RR) and
corresponding 95% confidence interval (CI).After serious scrutiny, a total of 14
cohort studies with 3194 patients were included in this meta-analysis. The pooled
RR revealed that there were no significant difference in tumor recurrence rate
between ECD and SP (fixed-effect model: RR?=?0.71, 95% CI?=?0.40-1.27, P?=?0.249;
random-effect model: RR?=?0.67, 95% CI?=?0.38-1.23, P?=?0.197). However, there
were significantly lower incidences of transient facial nerve dysfunction (FND),
permanent FND, and Frey's syndrome in patients of ECD group compared with SP
group.ECD might be a good choice in treatment of the benign parotid tumor that
were mobile, small, located in superficial lobe and without adhesion to facial
nerve; ECD should be performed by the experienced surgeons with ability of
dissection facial nerve, who should perform SP if tumor is found adhere to facial
nerve during an operation; and a multicenter randomized control trial study is
necessary to decide the optimal treatment of benign parotid tumor.
