Decompression is planned to match the levels where the spinal cord is being compressed. When imaging or intraoperative findings show stenosis spanning from the third cervical vertebra to the seventh, the laminoplasty or laminectomy is performed across that entire span to relieve pressure along all affected levels. In this case, the decompressed segment runs from C3 through C7, which makes sense because it addresses the full extent of the compression seen. Extending higher than C3 would involve levels not compressed, and stopping before C7 would leave residual stenosis, while including levels above C3 or below C7 would unnecessarily increase surgical risk.
