Abstract

Purpose The authors assess the role of flexible hollow core CO2 laser system (Omniguide system) in resection of intraspinal lipomas. Methods Eight patients with intraspinal lipomas were operated using an Omniguide laser system over a 22-month period. The age range varied between 6 months and 16 years. All of them had lipoma of the conus medullaris associated with lumbar subcutaneous lipoma. Two of these had previous surgery with resection of the subcutaneous part of the lipoma; in one of them, a partial resection of the conus medullaris lipoma had also been performed. In six, there were no obvious motor or sensory deficits whereas two had gross neurologic deficits, with the deficits occurring in one after the previous decompression. Resection of the conus lipoma, untethering of the spinal cord, and reconstruction of the decompressed conus was performed in all aided with Omniguide laser system. The power settings of the laser system ranged from 4 to 8 W. Results Subtotal to near-total resection was achieved in all. None of the patients developed any new motor or sensory deficits. Three had postoperative CSF leaks which initially required reoperation with graft resuturing and subsequently placement of lumboperitoneal shunt. One child with preexisting neurologic deficits improved in power over the next 12 months. Conclusion Flexible CO2 laser system was precise and convenient in decompressing the conus lipomas and untethering of the cord in lumbar spinal lipomas.
