Biportal Endoscopic Interlaminar Resection of Lumbar Facet Cyst: A Technical Note.
Article in Orthopedic research and reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Facet cysts are degenerative lesions near the facet joints, often seen in older adults with lumbar or radicular pain. They can compress nerves and cause significant morbidity. Treatment options range from conservative care to surgery. This article outlines the Biportal Endoscopic Spine Surgery (BESS) technique using interlaminar ipsilateral or contralateral approaches for symptom relief. Methods: This paper outlines the surgical techniques of Biportal Endoscopic Spine Surgery (BESS), utilizing both ipsilateral and contralateral interlaminar approaches. The choice of approach was determined by the location and characteristics of the synovial cyst. It details the surgical process, including portal placement, visualization, trajectory differences between approaches, and steps for cyst removal. Results: Biportal endoscopic spine surgery is a safe and effective minimally invasive treatment for symptomatic lumbar facet cysts, especially in elderly patients. The contralateral approach offers better visualization, improved dural dissection, and greater facet joint preservation, making it ideal for medial or adherent cysts. It also reduces nerve root manipulation and postoperative instability. In contrast, the ipsilateral approach is more suitable for lateral cysts. Conclusion: The choice between contralateral and ipsilateral approaches in biportal endoscopic facet cyst removal depends on cyst location and anatomical considerations. The contralateral approach is better suited for medial or adherent cysts, offering improved access with less facet disruption. Meanwhile, the ipsilateral approach provides a direct path for lateral cysts but may require more nerve manipulation and facet joint resection. A personalized surgical strategy is essential to optimize access, ensure nerve safety, and maintain spinal stability.
