PURPOSE: Symptomatic intraspinal extradural cysts of the cervical subaxial backbone are uncommon, however often require surgical procedure. Typical posterior decompression is the gold customary. Nevertheless, there’s growing expertise with endoscopic surgical strategies. The aim of the examine is to guage the technical implementation and outcomes of a full-endoscopic uniportal method by way of the posterior strategy in sufferers with symptomatic intraspinal extradural cysts of the cervical subaxial backbone.
METHODS: Seven consecutive sufferers with a subaxial location of symptomatic intraspinal extradural cysts had been decompressed in a full-endoscopic uniportal method by way of the posterior strategy between 2009 and 2015. Imaging and medical knowledge had been collected in follow-up examinations for 18 months.
RESULTS: In all instances, the cyst was fully eliminated and sufficient decompression was achieved utilizing the full-endoscopic uniportal method. One affected person developed a dural leak that was sutured and coated intraoperatively. No different issues requiring therapy had been noticed. All sufferers had a superb medical consequence with steady regression of the radicular and central nerve ache or neurological deficits. The imaging follow-up confirmed adequate decompression in all instances. No proof was discovered of accelerating instability throughout the follow-up interval.
CONCLUSION: The total-endoscopic uniportal operation with a posterior strategy permits the resection of the cyst and might decrease trauma and destabilization and has technical advantages and a low complication fee. It’s another surgical technique that may provide benefits and is taken into account by the authors to be the surgical strategy of selection for cervical subaxial intraspinal extradural cysts.
