In most known cases of lumbar and thoracic laminectomies,  [ dead link ] patients tend to recover slowly, with recurring pain or spinal stenosis persisting for up to 18 months after the procedure. The reason for lamina removal is rarely, if ever, because the lamina itself is diseased; rather, it is done to break the continuity of the rigid ring of the spinal canal to allow the soft tissues within the canal to: The recovery period after a laminectomy depends on the specific operative technique, with minimally invasive procedures having significantly shorter recovery periods than open surgery.
For some people, recovery can take weeks or months and may require long-term occupational and physical therapy. The actual bone removal may be carried out with a variety of surgical tools, including drills, rongeurs and lasers.

It is a major spine operation with residual scar tissue and may result in postlaminectomy syndrome. Most commonly, a laminectomy is performed to treat spinal stenosis. When the disabling symptoms of spinal stenosis are primarily neurogenic claudication and the laminectomy is done without spinal fusion, there is generally a rapid recovery and long term relief.
A laminectomy can treat severe spinal stenosis by relieving pressure on the spinal cord or nerve roots, provide access to a tumor or other mass lying in or around the spinal cord, or help in tailoring the contour of the vertebral column to correct a spinal deformity such as kyphosis.
