Laminotomy is different from a laminectomy in that the surgeon will remove only a portion of the lamina. The lamina is the bony roof of the spinal canal.
Pressure on the nerve roots or the spinal cord can be caused by bony spurs or by a herniated or bulging disc. This pressure is often referred to as spinal stenosis and can cause pain and weakness. The pressure is relieved by removing the lamina as well as any other source of compression such as bone spurs, a herniated disc, or disc bulges. Decompression of the nerve roots and the spinal cord relieves pain and other symptoms.
The patient’s overall health and condition will contribute to the surgeons approach to surgery. Minimally-invasive surgery and open surgery will be considered.
