Less invasive procedures such as hemilaminectomy and osteoplastic laminotomy have been described by other authors, but an approach that interferes with spinal stability to an even lesser extent seems desirable.<\/jats:p><jats:p>In an attempt to further reduce the need for bone removal, the authors used interlaminar fenestration (mostly unilateral) at one or more spinal levels to remove intramedullary, extramedullary, or extradural lesions, and even some lesions that extended over several spine segments. The authors present their experiences with this surgical approach in 78 patients harboring different intraspinal lesions. Up to 16 segments were fenestrated in one patient. Complete removal of the lesion was possible in most patients, and no postoperative spinal instabilities were observed in up to 8 years of follow up. Multilevel interlaminar fenestration, also called \u201cmultiple spinal keyhole surgery,\u201d is a feasible, safe, and effective approach to intraspinal lesions.<\/jats:p>","DOI":"10.3171\/spi.2007.6.5.485","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T13:14:13Z","timestamp":1201180453000},"page":"485-492","source":"Crossref","is-referenced-by-count":33,"title":["Unilateral
