Abstract

Abstract

Objective To assess the microsurgical resection of dumbbell-shape spinal schwannoma through enlarged intervertebral foramen approach.Methods We performed a retrospective review of 16 patients with dumbbell-shape spinal schwannomas who underwent microsurgical treatment by enlarged intervertebral foramen approach from March 2012 to December 2015 in our department.Preoperative imaging revealed the tumor bestriding intra-and extra-spinal canal, and the intervertebral foramen had been enlarged noticeably.Among which 8 were cervical, 3 were thoracic and 5 were lumbar spinal schwannomas.Results All tumors were removed completely.There was no intraoperative death.The average operation time was 3.2 hours, the average perioperative blood loss was 240 ml, the average hospital stay was 7.8 days postoperation.The average follow-up period was 10.7 months (ranged, 3 months to 36 months) .The symptoms and signs were improved and relieved significantly and no obvious complication or spinal deformity was found.Conclusion The dumbbell-shape spinal schwannoma predominantly located in extraintervertebral foramen could be removed via enlarged intervertebral foramen approach.This approach can aviod the destruction of spine bone structure, excessive exposure during operation and obtain maximum maintenance of spine stability.
