Objective
To review the literature and conduct a meta-analysis to determine the effectiveness and safety of the combined endoscopic–transfacial approach for parotid sialolith management.
Data Sources
PubMed 1946–, Embase 1947–, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Database of Systematic Reviews, Cochrane Database of Abstracts of Review Effects, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, Proquest Dissertations and Theses, and FirstSearch Proceedings to March 2015.
Review Methods
Published prospective or retrospective English-language studies with reported outcomes of more than one patient undergoing the combined endoscopic-transfacial procedure for parotid sialolithiasis were included. Two independent authors screened all eligible studies and reviewed and extracted data from relevant publications. Weighted pooled proportions for stone removal, symptom improvement, gland preservation, and complications were calculated.
Results
Ten studies, primarily retrospective single-institution studies, were included in the final analysis, with a total of 184 patients. Overall, the procedure was noted to be successful with low risk; the weighted pooled proportions were 0.99 (95% confidence interval [CI]: 0.97 to 1.00) for stone removal, 0.97 (95% CI: 0.93 to 0.99) for symptom improvement, 1 (95% CI: 0.99 to 1.00) for gland preservation, and 0.06 (95% CI: 0.01 to 0.15) for complications.
Conclusions
Although our analysis is primarily based on retrospective data, the evidence shown here suggests that the combined endoscopic–transfacial technique is an effective treatment for parotid gland sialolithiasis not amenable to intraoral or purely endoscopic removal. This approach results in high rates of symptom improvement and gland preservation. The complication rates are low, further supporting the use of this technique. Laryngoscope, 2017
