Endoscopic versus open microvascular decompression for trigeminal neuralgia: a systematic review and comparative meta-analysis (original) (raw)

OBJECTIVEMicrovascular decompression (MVD) is commonly used in the treatment of trigeminal neuralgia (TN) with positive clinical outcomes. Fully endoscopic MVD (E-MVD) has been proposed as an effective minimally invasive alternative, but a comparative review of the two approaches has not been conducted. The authors performed a meta-analysis of studies, comparing patient outcome rates and complications for the open versus the endoscopic technique.METHODSThe PubMed/MEDLINE and Ovid databases were searched for studies published from database inception to 2017. The search terms used included, but were not limited to, “open microvascular decompression,” “microvascular decompression for trigeminal neuralgia,” and “endoscopic decompression for trigeminal neuralgia.” Criteria for inclusion of studies in the meta-analysis were established as follows: adult patients, clinical studies with ≥ 10 patients (excluding case studies to obtain a higher volume of outcome rates), utilization of open MV...
